Figure 42 This is a flowchart showing an example of the workpiece processing method in the first embodiment. Figure 43 This is a flowchart showing an example of a method for repairing chuck jaws in the first embodiment.

[0018] like Figure 1 As illustrated, the chuck jaws 1 in the first embodiment are components supported by the chuck body 31. More specifically, the chuck jaws 1 are supported by the chuck body 31 so as to be movable in a first direction DR1 away from the first axis AX (in other words, the rotation axis of the chuck body 31) and a second direction DR2 closer to the rotation axis. Figure 1 In the example described, the first direction DR1 corresponds to a radial direction away from the rotation axis of the chuck body 31. In addition, the second direction DR2 corresponds to a direction opposite to the first direction DR1.

[0019] exist Figure 1 In the example described, the chuck body 31 supports a plurality of chuck jaws 1. In the following description, the first chuck jaw 1A among the plurality of chuck jaws 1 will be described as a representative.

[0020] exist Figure 1 and Figure 2In the example described, the chuck body 31 includes a movable portion 32 and a base portion 33 that movably supports the movable portion 32. Furthermore, the first chuck jaw 1A is movable together with the movable portion 32 of the chuck body 31 in a first direction DR1 away from the first axis AX (in other words, the rotational axis of the chuck body 31). Furthermore, the first chuck jaw 1A is movable together with the movable portion 32 of the chuck body 31 in a second direction DR2 toward the first axis AX.

[0021] like Figure 2 As illustrated, the first chuck jaw 1A includes a base 11 attached to a chuck body 31 , a jaw body 13 , and a metal layer 15 .

[0022] The metal layer 15 is attached to the claw body 13 and contacts the workpiece W. The first metal material constituting the metal layer 15 has lower thermal conductivity than the second metal material constituting the claw body 13 . The metal layer 15 is formed by solidifying molten metal on the claw body 13 , for example.

[0023] Next, a method for manufacturing the first chuck jaw 1A in the first embodiment will be described.

[0024] like Figure 3 As shown in the example, in the first step ST1, the first block BL1 having the base 11 and the jaw body 13 is mounted on the chuck body 31, which is rotatable about the first axis AX. The first step ST1 is the first mounting process. Alternatively, the base 11 and the jaw body 13 may be integrally formed in the first block BL1. Alternatively, the base 11 may be fixed to the jaw body 13 via a fixing member.

[0025] The first mounting process (first step ST1 ) includes mounting the base portion 11 of the first block BL1 to the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31 ).

[0026] like Figure 4 As shown in the example, in the second step ST2, the claw body 13 is cut. The second step ST2 is the first cutting step. The first cutting step (second step ST2) includes cutting the claw body 13 with the base 11 of the first block BL1 attached to the chuck body 31 to form a base surface 130 on the claw body 13.

[0027] In addition, when the base surface 130 is previously formed on the jaw body 13 before the first block BL1 is attached to the chuck body 31 , the second step ST2 is omitted.

[0028] like Figure 5As shown in the example, in the third step ST3, the metal layer 15 is added to the jaw body 13. The third step ST3 is the first adding step. The first adding step (third step ST3) includes adding the metal layer 15 for contacting the workpiece W to the jaw body 13 while the base 11 is attached to the chuck body 31.

[0029] The first metal material G1 constituting the metal layer 15 has lower thermal conductivity than the second metal material constituting the claw body 13 .

[0030] like Figure 6 As shown in the example, it is assumed that the preheated workpiece W held by the chuck jaws 1 ' in the comparative example is subjected to additive manufacturing. Figure 6 In the example described, during additive manufacturing, heat is dissipated from the workpiece W to the chuck jaws 1 ′, causing the temperature of the workpiece W to drop. This drop in the workpiece W temperature can cause material addition failure to the workpiece W (more specifically, damage to the material added to the workpiece W).

[0031] In contrast, in the chuck jaws 1 of the first embodiment, the metal layer 15 having low thermal conductivity is added to the jaw body 13 . Furthermore, in the method for manufacturing the chuck jaws of the first embodiment, the metal layer 15 having low thermal conductivity is added to the jaw body 13 .

[0032] In the first embodiment, when the workpiece W is gripped by the plurality of chuck jaws 1 including the first chuck jaw 1A, the metal layer 15 having low thermal conductivity comes into contact with the workpiece W. Therefore, in the additive manufacturing process of adding material to the workpiece W (see Figure 2 ), heat dissipation from the workpiece W to the first chuck jaw 1A can be suppressed, thereby suppressing a drop in the temperature of the workpiece W. In this way, poor addition of material to the workpiece W (more specifically, breakage of the material added to the workpiece W) can be prevented or suppressed.

[0033] In the chuck jaws 1 of the first embodiment, the metal layer 15 is attached to the jaw body 13 without using a fixing member. In this case, there is no need to prepare a fixing member to fix the metal layer 15 to the jaw body 13. Therefore, a technology for suppressing heat conduction from the workpiece W to the first chuck jaw 1A can be provided at low cost.

[0034] Consider a case where a first member having low thermal conductivity is fixed to the claw body 13 by a fixing member. In this case, the shape of the claw body 13 cannot be flexibly changed according to the shape of the workpiece W. For example, if the shape of the claw body 13 is changed according to the shape of the workpiece W, there is a possibility that the shape of the first member will no longer match the shape of the claw body 13.

[0035] In contrast, in the method for manufacturing the chuck jaws of the first embodiment, the shape of the jaw body 13 can be flexibly changed according to the shape of the workpiece W to be gripped. Furthermore, the position where the metal layer 15 is to be provided, the range where the metal layer 15 is to be provided, the thickness of the metal layer 15, and the like can be easily set according to the shape of the workpiece W.

[0036] (Optional additional structure) Next, refer to Figures 1 to 43 An optional additional structure that can be adopted in the first chuck jaws 1A, the chuck jaw manufacturing method, the workpiece processing method, and the chuck jaw repair method in the first embodiment will be described.

[0037] (First Metal Material Constituting the Metal Layer 15 and Second Metal Material Constituting the Claw Body 13) The claw body 13 is formed, for example, from steel (more specifically, medium carbon steel). In other words, the second metal material constituting the claw body 13 is, for example, steel (more specifically, medium carbon steel). In this specification, medium carbon steel refers to carbon steel having a carbon content of 0.25% by weight or greater and 0.6% by weight or less. The second metal material constituting the claw body 13 is not limited to medium carbon steel or steel and may be any material.

[0038] The metal layer 15 is formed of, for example, stainless steel. Alternatively, the metal layer 15 may be formed of a nickel alloy having nickel as a main component (for example, a nickel-chromium alloy containing nickel as a main component and chromium as a second component). Further alternatively, the metal layer 15 may be formed of a cobalt alloy having cobalt as a main component (for example, a cobalt-chromium alloy containing cobalt as a main component and chromium as a second component). Further alternatively, the metal layer 15 may be formed of mold steel with low thermal conductivity or high-speed steel with low thermal conductivity. In other words, the first metal material constituting the metal layer 15 is, for example, stainless steel, a nickel alloy (more specifically, a nickel-chromium alloy), a cobalt alloy (more specifically, a cobalt-chromium alloy), a mold steel with low thermal conductivity, and high-speed steel with low thermal conductivity. In addition, the first metal material constituting the metal layer 15 is not limited to the above-mentioned examples.

[0039] The thermal conductivity of the first metal material constituting the metal layer 15 is, for example, 0.5 times or less, more preferably 0.4 times or less, and even more preferably 0.3 times or less, the thermal conductivity of the second metal material constituting the claw body 13. Furthermore, to facilitate comparison between the thermal conductivity of the first metal material constituting the metal layer 15 and the thermal conductivity of the second metal material constituting the claw body 13, the term "thermal conductivity" in this specification refers to thermal conductivity at room temperature.

[0040] In the first embodiment, the portion of the first chuck jaw 1A that contacts the workpiece W is preferably entirely composed of the metal layer 15. In this case, the jaw body 13, which has a relatively high thermal conductivity, does not contact the workpiece W. Therefore, heat conduction from the workpiece W to the first chuck jaw 1A can be effectively suppressed, effectively preventing a decrease in the temperature of the workpiece W.

[0041] exist Figure 8 In the example described, the metal layer 15 includes a first portion 15a that contacts the outer peripheral surface Wa of the workpiece W, and a second portion 15b that contacts the end surface of the workpiece W (more specifically, the end surface of the workpiece W in the third direction DR3). This configuration suppresses heat dissipation from the outer peripheral surface Wa of the workpiece W to the first chuck jaw 1A, and also suppresses heat dissipation from the end surface of the workpiece W to the first chuck jaw 1A. Therefore, when the outer peripheral surface Wa of the workpiece W is gripped by the plurality of chuck jaws 1, including the first chuck jaw 1A, a decrease in the temperature of the workpiece W can be effectively suppressed. In this specification, the end surface of the workpiece W in the third direction DR3 is referred to as the "first end surface Wb," and the end surface of the workpiece W in the fourth direction DR4 is referred to as the "second end surface Wd."

[0042] Alternatively, in the first chuck jaw 1A, the first portion 15a that contacts the outer peripheral surface Wa of the workpiece W may be formed of the metal layer 15 of the first metal material, while the second portion 15b that contacts the first end surface Wb of the workpiece W may be formed of the jaw body 13 of the second metal material. Further alternatively, in the first chuck jaw 1A, the first portion 15a that contacts the outer peripheral surface Wa of the workpiece W may be formed of the jaw body 13 of the second metal material, while the second portion 15b that contacts the first end surface Wb of the workpiece W may be formed of the metal layer 15 of the first metal material. In these cases, the temperature drop of the workpiece W can be suppressed compared to a case where the metal layer 15 is not added at all.

[0043] exist Figure 2 In the example described, the metal layer 15 includes a third portion 15c that contacts the inner circumferential surface Wc of the workpiece W, and a second portion 15b that contacts the first end surface Wb of the workpiece W. In this case, heat dissipation from the inner circumferential surface Wc of the workpiece W to the first chuck jaw 1A can be suppressed, and heat dissipation from the first end surface Wb of the workpiece W to the first chuck jaw 1A can also be suppressed. Therefore, when the inner circumferential surface Wc of the workpiece W is gripped by the plurality of chuck jaws 1, including the first chuck jaw 1A, a decrease in the temperature of the workpiece W can be effectively suppressed.

[0044] Alternatively, in the first chuck jaw 1A, the third portion 15c that contacts the inner circumferential surface Wc of the workpiece W may be formed of the metal layer 15 made of the first metal material, while the second portion 15b that contacts the first end surface Wb of the workpiece W may be formed of the jaw body 13 made of the second metal material. Further alternatively, in the first chuck jaw 1A, the third portion 15c that contacts the inner circumferential surface Wc of the workpiece W may be formed of the jaw body 13 made of the second metal material, while the second portion 15b that contacts the first end surface Wb of the workpiece W may be formed of the metal layer 15 made of the first metal material. In these cases, the temperature drop of the workpiece W can be suppressed compared to cases where the metal layer 15 is not added.

[0045] like Figure 9 As shown in the example, the metal layer 15 may include a first portion 15a that contacts the outer peripheral surface Wa of the workpiece W, a second portion 15b that contacts the first end surface Wb of the workpiece W, and a third portion 15c that contacts the inner peripheral surface of another workpiece W2. In this case, the first chuck jaw 1A can be used to grip a variety of workpieces.

[0046] like Figure 10 、 Figure 11 As shown in the example, the metal layer 15 may be an additively manufactured layer 151. In other words, the metal layer 15 may be a layer added to the jaw body 13 by additive manufacturing. In the case where the metal layer 15 is the additively manufactured layer 151, the thickness of the metal layer 15 can be easily increased. In the case where the metal layer 15 has a sufficient thickness, heat conduction from the workpiece W to the chuck jaw 1 can be effectively suppressed. In addition, in the case where the metal layer 15 has a sufficient thickness, the groove 161 can be easily formed on the surface 16 of the metal layer 15 (see Figure 13 ).

[0047] The thickness of the metal layer 15 is, for example, not less than 0.5 mm and not more than 5 mm. Figure 10 In the example described, the thickness H1 of the first portion 15a of the metal layer 15 and the thickness H2 of the second portion 15b of the metal layer 15 are both 0.5 mm or more and 5 mm or less. Figure 11 In the example described, the thickness H2 of the second portion 15b of the metal layer 15 and the thickness H2 of the third portion 15c of the metal layer 15 are both 0.5 mm or more and 5 mm or less. Figure 10 In the example described, the thickness H2 of the second portion 15b may be greater than the thickness H1 of the first portion 15a, may be less than the thickness H1 of the first portion 15a, or may be equal to the thickness H1 of the first portion 15a. Figure 11In the example described above, the thickness H2 of the second portion 15b may be greater than, less than, or equal to the thickness H3 of the third portion 15c. The thickness of the metal layer 15 is not limited to the above example.

[0048] When the metal layer 15 is the additively manufactured layer 151, it is easy to regenerate the metal layer 15. For example, when the metal layer 15 is worn out by using the chuck jaws 1, the metal layer 15 can be regenerated by adding the metal layer 15 again.

[0049] In the case where the metal layer 15 is an additively manufactured layer 151, it is easy to add the metal layer 15 only to the surface of the first chuck jaw 1A that is used to contact the workpiece W. Figure 10 In the example described, among the multiple surfaces of the first chuck jaw 1A, the first surface 16-1 for contacting the outer peripheral surface Wa of the workpiece W and the second surface 16-2 for contacting the first end surface Wb of the workpiece W are formed of the metal layer 15. Figure 11 In the example described, among the multiple surfaces of the chuck jaws 1, the third surface 16-3 for contacting the inner circumferential surface Wc of the workpiece W and the second surface 16-2 for contacting the first end surface Wb of the workpiece W are formed of the metal layer 15. By omitting the addition of the metal layer 15 to the surfaces of the chuck jaws 1 that do not contact the workpiece W, the increase in machining cost and the increase in machining time associated with the addition of the metal layer 15 can be suppressed.

[0050] When the metal layer 15 is an additively manufactured layer 151, the metal layer 15 can be added to the jaw body 13 of the first chuck jaw 1A holding the workpiece W using the additive manufacturing apparatus 50 that performs additive manufacturing on the workpiece W. In other words, a single additive manufacturing apparatus 50 can be used to perform both machining of the first chuck jaw 1A and machining of the workpiece W.

[0051] exist Figure 12 In the example described, in the metal layer 15, the first surface 16-1 that contacts the outer peripheral surface Wa of the workpiece W is an arc-shaped surface. The arc-shaped surface preferably has a curvature radius substantially equal to the radius of the outer peripheral surface Wa of the workpiece W. In addition, when the chuck jaws 1 are mounted on the chuck body 31, the center line of the arc-shaped surface is preferably substantially coaxial with the first axis AX. Alternatively, the first surface 16-1 that contacts the outer peripheral surface Wa of the workpiece W may also be a flat surface. Figure 12 In the described example, the first surface 16 - 1 is a surface extending in a direction parallel to the first axis AX.

[0052] exist Figure 12 In the example described, the second surface 16-2 of the metal layer 15 that contacts the first end surface Wb of the workpiece W is a flat surface. Figure 12 In the described example, the second surface 16 - 2 is a surface perpendicular to the first axis AX.

[0053] In the metal layer 15, the third surface 16-3 (see Figure 11 ) can be an arcuate surface or a flat surface. When the third surface 16-3 is an arcuate surface, the arcuate surface preferably has a curvature radius substantially equal to the radius of the inner circumferential surface Wc of the workpiece W. The third surface 16-3 is a surface extending in a direction parallel to the rotation axis of the chuck body 31 (in other words, the first axis AX).

[0054] exist Figure 11 In the example described, the second surface 16-2 for contacting the first end surface Wb of the workpiece W is a flat surface. Figure 11 In the example described, the second surface 16 - 2 is a surface perpendicular to the rotation axis of the chuck body 31 (in other words, the first axis AX).

[0055] exist Figure 10 In the example described, the surface 16 of the metal layer 15 (more specifically, the first surface 16-1 and the second surface 16-2) is a cut surface 16s (in other words, a surface formed by cutting). Figure 11 In the described example, the surface 16 of the metal layer 15 (more specifically, the third surface 16 - 3 and the second surface 16 - 2 ) is a cut surface 16 s (in other words, a surface formed by cutting).

[0056] When the surface 16 of the metal layer 15 is formed by cutting, the surface 16 can be made smooth. In this case, damage to the workpiece W in contact with the metal layer 15 can be prevented. Furthermore, grinding may be performed after cutting. In this specification, the surface formed by grinding after cutting is considered one embodiment of the cut surface 16s.

[0057] exist Figure 10 、 Figure 11 In the described example, the surface 16 of the metal layer 15 (more specifically, the first surface 16 - 1 and the second surface 16 - 2 , or the third surface 16 - 3 and the second surface 16 - 2 ) is a smooth surface without grooves or protrusions.

[0058] Alternatively, if Figure 13 、 Figure 14As illustrated, the surface 16 of the metal layer 15 may also be a smooth surface having grooves 161. More specifically, the first surface 16-1 of the metal layer 15 may also be a smooth surface having grooves 161-1. The second surface 16-2 of the metal layer 15 may also be a smooth surface having grooves 161-2. Furthermore, the third surface 16-3 of the metal layer 15 may also be a smooth surface having grooves 161-3. A grooved smooth surface refers to a surface having grooves formed therein. Therefore, in a grooved smooth surface, the portion other than the grooves is smooth.

[0059] When the surface 16 of the metal layer 15 has the grooves 161 , the contact area between the metal layer 15 and the workpiece W is reduced. Therefore, heat dissipation from the workpiece W to the first chuck jaw 1A can be further suppressed.

[0060] exist Figures 8 to 14 In the example described, a portion of the surface of the jaw body 13 of the first chuck jaw 1A is covered with the first metal material constituting the metal layer 15. Furthermore, in another portion of the surface of the jaw body 13 of the first chuck jaw 1A, the second metal material constituting the jaw body 13 is exposed, uncovered by the first metal material. By covering the portion of the jaw body 13 surface that contacts the workpiece W with the first metal material, while leaving the portion of the jaw body 13 surface that does not contact the workpiece W exposed, the amount of first metal material added to the jaw body 13 can be reduced. Furthermore, the time required to attach the first metal material to the jaw body 13 can be shortened.

[0061] (Base 11 of First Chuck Jaw 1A) exist Figure 2 、 Figure 8 In the example described above, the first chuck jaw 1A includes a base 11 mounted on the chuck body 31. The base 11 may include a first engaging portion 112 that engages with an engaging portion 312 formed on the chuck body 31. Figure 2 、 Figure 8 In the described example, the attachment position of the first chuck jaw 1A with respect to the movable portion 32 of the chuck body 31 can be adjusted by adjusting the relative position of the first engaging portion 112 with respect to the engaging portion 312 .

[0062] (held portion 12) The first chuck jaw 1A may also have a held portion 12 held by a jaw replacement device. The held portion 12 is provided on the base 11 or the jaw body 13. Figure 15 In the example described, the held portion 12 is provided on the base portion 11. Figure 15 In the example described, the held portion 12 includes a second engaging portion 122 that can engage with the claw replacement device. Figure 17As shown in the example, it is preferable that the held portion 12 (more specifically, the second engaging portion 122 ) is exposed to the outside of the chuck body 31 when the first chuck jaw 1A is attached to the chuck body 31 . In this case, the jaw replacing device 102 can easily access the held portion 12 .

[0063] (Base surface 130 of claw body 13) The claw body 13 has a base surface 130 to which the metal layer 15 is attached. Figure 4 In the example described above, the base surface 130 is a cut surface. When the base surface 130 is a cut surface, impurities are removed from the base surface 130, and the base surface 130 becomes a smooth surface.

[0064] (Method for manufacturing chuck jaws) The chuck jaws formed by the manufacturing method of the chuck jaws in the first embodiment may be Figures 1 to 15 Any of the first chuck jaws 1A exemplified in the drawings may be other chuck jaws.

[0065] like Figure 16 and Figure 17 As illustrated, in the first step ST1, the first block BL1 having the base 11 and the jaw body 13 is mounted on the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31) rotatable about the first axis AX. The first step ST1 is the first mounting process. Alternatively, the base 11 and the jaw body 13 may be integrally formed in the first block BL1. Alternatively, the base 11 may be secured to the jaw body 13 via a securing member.

[0066] In the first block BL1, the outer shape of the claw body 13 can also be a roughly rectangular parallelepiped shape. In this case, the degree of freedom of the shape of the manufactured chuck claw 1 becomes greater. In other words, by cutting the roughly rectangular parallelepiped claw body 13, it is possible to form a claw body 13 of any shape. Figure 16 In the described example, the first block BL1 is a new block.

[0067] Alternatively, the outer shape of the jaw body 13 in the first block BL1 can be similar to the outer shape of the final jaw body. In this case, the volume of the portion to be removed from the first block BL1 is reduced, and the time required to cut the jaw body 13 can be shortened. The first block BL1 can be new or old. For example, the first block BL1 can also be a used chuck jaw.

[0068] exist Figure 16In the example described, the base 11 of the first block BL1 has a first engaging portion 112 that engages with the chuck body 31. Furthermore, the first block BL1 has a held portion 12 held by the jaw changing device 102. The held portion 12 may also include a second engaging portion 122 that can engage with the jaw changing device 102.

[0069] exist Figure 16 and Figure 17 In the example described, the first mounting step includes the jaw changing device 102 transferring the first block BL1 to the chuck body 31 and the jaw changing device 102 mounting the first block BL1 on the chuck body 31. In this case, the jaw changing device 102 automatically mounts the first block BL1 on the chuck body 31.

[0070] Alternatively, the first mounting step may be performed manually. In this case, the held portion 12 (more specifically, the second engaging portion 122) may be omitted.

[0071] like Figure 18 As illustrated, in the second step ST2, the jaw body 13 is cut. The second step ST2 is a first cutting step. The first cutting step includes cutting the jaw body 13 while the base portion 11 of the first block BL1 is attached to the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31) to form a base surface 130 on the jaw body 13. The first cutting step (second step ST2) includes cutting the first block BL1 to form a base surface 130 having a shape that substantially corresponds to a portion of the surface of the workpiece W.

[0072] exist Figure 18 In the example described, the first cutting process (second step ST2) includes cutting the claw body 13 to form a first base surface 131 extending in a direction parallel to the first axis AX (in other words, the rotation axis of the chuck body 31) and a second base surface 132 perpendicular to the first axis AX on the claw body 13.

[0073] exist Figure 18 In the described example, the first cutting step (second step ST2 ) includes cutting the pawl body 13 with the cutting tool T to form the first base surface 131 and / or the second base surface 132 on the pawl body 13 .

[0074] like Figure 18 As illustrated, the first cutting step (second step ST2) may include forming the first base surface 131 and / or the second base surface 132 on the jaw body 13 by turning. More specifically, the first cutting step (second step ST2) may include repeatedly bringing the cutting tool T into contact with the jaw body 13 while the chuck body 31 to which the base 11 is attached is rotated about the first axis AX (see arrow R1).

[0075] In addition, when the base surface 130 is previously formed on the jaw body 13 before the first block BL1 is attached to the chuck body 31 , the second step ST2 is omitted.

[0076] like Figure 19 As illustrated, in the third step ST3, the metal layer 15 is added to the claw body 13. The third step ST3 is a first adding process.

[0077] The first adding step (third step ST3) includes adding a metal layer 15, which is intended to contact the workpiece W, to the jaw body 13 while the base 11 is attached to the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31). The first metal material G1 constituting the metal layer 15 has a lower thermal conductivity than the second metal material constituting the jaw body 13.

[0078] exist Figure 19 In the example described, the first adding process (third step ST3) is performed using the metal adding device 5. Figure 19 In the described example, the metal adding device 5 is an additive manufacturing device 50. The additive manufacturing device 50 is sometimes also referred to as a build-up welding device.

[0079] exist Figure 19 In the example described, the additive manufacturing apparatus 50 supplies the first metal material G1 (more specifically, the metal powder g1 of the first metal material) to the claw body 13 (more specifically, the base surface 130), and irradiates the claw body 13 (more specifically, the base surface 130) with laser light LB. As a result, the first metal material heated by the energy of the laser light LB melts, and the molten metal adheres to the claw body 13 (more specifically, the base surface 130). In this way, the metal layer 15 is formed in such a way that the first metal material adheres to the claw body 13 (more specifically, the base surface 130) and covers the base surface 130. Figure 19 In the example described above, a portion of the second metal material constituting the base surface 130 is also melted by the laser beam LB. Therefore, the second metal material constituting the base surface 130 is firmly bonded to the first metal material supplied to the base surface 130 .

[0080] Alternatively, the metal adding device 5 may be a spraying device that adds the first metal material to the claw body 13 (more specifically, the base surface 130). The spraying device adds the first metal material to the claw body 13 (more specifically, the base surface 130) by high-velocity flame spraying, gas flame spraying, plasma spraying, arc spraying, cold spraying, or the like.

[0081] like Figure 19As illustrated, the first attaching step (third step ST3) may also include rotating the claw body 13 about the first axis AX (see arrow R2) and attaching the metal layer 15 to the claw body 13 rotated about the first axis AX. Rotating the claw body 13 about the first axis AX eliminates the need to change the position of the metal attaching device 5 during the first attaching step, or minimizes the change in the position of the metal attaching device 5. Minimizing the change in the position of the metal attaching device 5 improves the accuracy of forming the metal layer 15.

[0082] exist Figure 19 and Figure 20 In the example described, the first adding step (third step ST3) includes adding the metal layer 15 to both the first base surface 131 and the second base surface 132. More specifically, Figure 19 In the described example, the first adding step (third step ST3) involves adding a first metal material to the second base surface 132 of the claw body 13 using the additive manufacturing apparatus 50. The additive manufacturing apparatus 50 supplies the first metal material to the second base surface 132 and irradiates the second base surface 132 with laser light LB. As a result, the first metal material, heated by the energy of the laser light LB, melts, and the molten metal adheres to the second base surface 132. In this manner, the metal layer 15 is formed to cover the second base surface 132.

[0083] exist Figure 20 In the described example, the first adding step (third step ST3) involves adding a first metal material to the first base surface 131 of the claw body 13 using the additive manufacturing apparatus 50. The additive manufacturing apparatus 50 supplies the first metal material to the first base surface 131 and irradiates the first base surface 131 with laser light LB. As a result, the first metal material, heated by the energy of the laser light LB, melts, and the molten metal adheres to the first base surface 131. In this manner, the metal layer 15 is formed to cover the first base surface 131.

[0084] exist Figure 19 and Figure 20 In the example described, the first metal material is added to the first base surface 131 after being added to the second base surface 132. Alternatively, the first metal material may be added to the second base surface 132 after being added to the first base surface 131.

[0085] like Figure 21As illustrated, in the fourth step ST4, the metal layer 15 is cut. The fourth step ST4 is a second cutting step. The second cutting step (fourth step ST4) includes cutting the metal layer 15 while the base 11 is attached to the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31) to smooth the surface of the metal layer 15. The second cutting step (fourth step ST4) includes cutting the metal layer 15 to form a cut surface 16s having a shape corresponding to a portion of the surface of the workpiece W.

[0086] exist Figure 21 and Figure 22 In the recorded example, the second cutting process (fourth step ST4) includes cutting the metal layer 15 to form a first cutting surface 16s-1 extending in a direction parallel to the first axis AX (in other words, the rotation axis of the chuck body 31) and a second cutting surface 16s-2 perpendicular to the first axis AX on the metal layer 15.

[0087] exist Figure 21 and Figure 22 In the described example, the second cutting step (fourth step ST4) includes cutting the metal layer 15 with a cutting tool T to form a first cutting surface 16s-1 and / or a second cutting surface 16s-2 in the metal layer 15. The cutting tool used to cut the metal layer 15 may be the same as or different from the cutting tool used to cut the cutting claw body 13.

[0088] like Figure 21 and Figure 22 As illustrated, the second cutting step (fourth step ST4) may also include forming the first cutting surface 16s-1 and / or the second cutting surface 16s-2 on the metal layer 15 by turning. More specifically, the second cutting step (fourth step ST4) may also include repeatedly bringing the cutting tool T into contact with the metal layer 15 while the chuck body 31 to which the base 11 is attached is rotated about the first axis AX (see arrow R3).

[0089] In addition, if Figure 23 As illustrated, the second cutting process (fourth step ST4) may also include forming a groove 161 on the surface of the metal layer 15. For example, the second cutting process (fourth step ST4) may also include forming a groove 161-1 on the first surface 16-1 of the metal layer 15 by bringing a tool such as the grooving tool T3 into contact with the metal layer 15 rotating around the first axis AX (see arrow R4). In addition, the second cutting process (fourth step ST4) may also include forming a groove 161-2 on the second surface 16-2 of the metal layer 15 by bringing a tool such as the grooving tool T3 into contact with the metal layer 15 rotating around the first axis AX. In addition, the process of forming the groove 161 on the surface 16 of the metal layer 15 may be omitted.

[0090] Through the above-described multiple steps, the chuck jaws 1 (for example, the first chuck jaws 1A) are formed.

[0091] The manufacturing method of the chuck jaws may also include a disassembly step (fifth step ST5 ). The disassembly step is a step of removing the formed first chuck jaws 1A (in other words, the first chuck jaws 1A having the base 11 , the jaw body 13 , and the metal layer 15 attached to the jaw body 13 ) from the chuck body 31 .

[0092] exist Figure 24 In the example described, the disassembly process includes the jaw replacement device 102 operating the operating portion 39 to release the engagement between the chuck body 31 and the first engaging portion 112 of the base 11. Figure 24 In the described example, the jaw changing device 102 presses the operating portion 39 provided on the chuck body 31 to release the engagement between the engaging portion 312 of the chuck body 31 and the first engaging portion 112 of the base 11 .

[0093] exist Figure 25 In the described example, the disassembly step includes the jaw changing device 102 pulling out the first chuck jaw 1A in a direction away from the first axis AX.

[0094] exist Figure 24 and Figure 25 In the described example, the disassembly process is automatically performed using the claw replacement device 102. Alternatively, the disassembly process may be performed manually.

[0095] The method for manufacturing the chuck jaws may include a first transfer step (sixth step ST6 ). The first transfer step includes transferring the first chuck jaws 1A removed from the chuck body 31 to the stocker 101 .

[0096] exist Figure 26 In the example described, the transfer step includes the jaw changing device 102 transferring the first chuck jaw 1A to the stocker 101. The jaw changing device 102 may include a first unit 102a for removing the first chuck jaw 1A from the chuck body 31 and a second unit 102b for transferring the first chuck jaw 1A to the stocker 101.

[0097] The first chuck jaws 1A transferred to the stocker 101 may be held by the jaw holders 101 a .

[0098] exist Figure 26 In the described example, the first transfer step is automatically performed using the claw replacement device 102. Alternatively, the first transfer step may be performed manually.

[0099] (Second chuck jaw 1B and third chuck jaw 1C) The second chuck jaw 1B has the same structure as the first chuck jaw 1A. In the above description of the first chuck jaw 1A, by replacing "first chuck jaw 1A," "base 11," "jaw body 13," and "metal layer 15" with "second chuck jaw 1B," "second base 11B," "second jaw body 13B," and "second metal layer 15B," respectively, the above description of the first chuck jaw 1A can be considered as the description of the second chuck jaw 1B, and any duplicate description of the second chuck jaw 1B will be omitted.

[0100] The third chuck jaw 1C has the same structure as the first chuck jaw 1A. In the above description of the first chuck jaw 1A, by replacing "first chuck jaw 1A," "base 11," "jaw body 13," and "metal layer 15" with "third chuck jaw 1C," "third base 11C," "third jaw body 13C," and "third metal layer 15C," respectively, the above description of the first chuck jaw 1A can be considered as a description of the third chuck jaw 1C, and any duplicate description of the third chuck jaw 1C will be omitted.

[0101] (Method for Manufacturing Second Chuck Jaw 1B and Method for Manufacturing Third Chuck Jaw 1C) The method for manufacturing the second chuck jaw 1B includes the same steps as the method for manufacturing the first chuck jaw 1A. In the description of the method for manufacturing the first chuck jaw 1A, by replacing "first chuck jaw 1A," "base 11," "jaw body 13," "metal layer 15," and "first block BL1" with "second chuck jaw 1B," "second base 11B," "second jaw body 13B," "second metal layer 15B," and "second block BL2," respectively, the description of the method for manufacturing the first chuck jaw 1A can be considered the description of the method for manufacturing the second chuck jaw 1B, and any repetitive description of the method for manufacturing the second chuck jaw 1B will be omitted.

[0102] The method for manufacturing the third chuck jaw 1C includes the same steps as the method for manufacturing the first chuck jaw 1A. In the description of the method for manufacturing the first chuck jaw 1A, by replacing "first chuck jaw 1A," "base 11," "jaw body 13," "metal layer 15," and "first block BL1" with "third chuck jaw 1C," "third base 11C," "third jaw body 13C," "third metal layer 15C," and "third block," respectively, the description of the method for manufacturing the first chuck jaw 1A can be considered the description of the method for manufacturing the third chuck jaw 1C, and any repetitive description of the method for manufacturing the third chuck jaw 1C will be omitted.

[0103] (Manufacturing of Multiple Chuck Jaws 1) The method for manufacturing the chuck jaws in the first embodiment may include manufacturing a plurality of chuck jaws including the first chuck jaw 1A and the second chuck jaw 1B.

[0104] like Figure 16 As illustrated, the manufacturing method of the chuck jaw in the first embodiment may also include installing the base 11 of the first block BL1 having the base 11 and the jaw body 13 to the chuck body 31 rotatable around the first axis AX, and installing the second base 11B of the second block BL2 having the second base 11B and the second jaw body 13B to the chuck body 31.

[0105] like Figure 18 As illustrated, the method for manufacturing the chuck jaws in the first embodiment may include cutting the jaw body 13 and cutting the second jaw body 13B. Figure 18 In the described example, the jaw body 13 and the second jaw body 13B are both cut with the base 11 of the first block BL1 and the second base 11B of the second block BL2 mounted on the chuck body 31 .

[0106] like Figure 18 As illustrated, the manufacturing method of the chuck jaws in the first embodiment may also include rotating the chuck body 31 to which the first block BL1 and the second block BL2 are mounted about the first axis AX, and repeatedly bringing the cutting tool T into contact with the first block BL1 and the second block BL2 rotating about the first axis AX. Figure 18 In the example described, the base surface 130 of the first block BL1 and the base surface 130B of the second block BL2 are formed in parallel using the turning tool T1. In other words, the first block BL1 and the second block BL2 are turned substantially simultaneously using the turning tool T1.

[0107] like Figure 19 and Figure 20 As illustrated, the method for manufacturing the chuck jaws in the first embodiment may also include adding the metal layer 15 to the jaw body 13 and adding the second metal layer 15B to the second jaw body 13B. The material constituting the second metal layer 15B is the same as the material constituting the metal layer 15 (i.e., the first metal material G1). Figure 19 and Figure 20 In the described example, the metal layer 15 is attached to the jaw body 13 and the second metal layer 15B is attached to the second jaw body 13B while both the base 11 and the second base 11B are mounted on the chuck body 31 .

[0108] like Figure 19 and Figure 20As illustrated, the method for manufacturing the chuck jaws of the first embodiment may also include rotating the jaw body 13 and the second jaw body 13B along with the chuck body 31 about the first axis AX, attaching the metal layer 15 to the jaw body 13 while it is rotated about the first axis AX, and attaching the second metal layer 15B to the second jaw body 13B while it is rotated about the first axis AX. Rotating the jaw body 13 and the second jaw body 13B about the first axis AX eliminates the need to change the position of the metal adding device 5 during the first attaching step, or only requires minimal change in the position of the metal adding device 5.

[0109] like Figure 21 As illustrated, the method for manufacturing the chuck jaws in the first embodiment may include cutting the metal layer 15 to smooth the surface of the metal layer 15 and cutting the second metal layer 15B to smooth the surface of the second metal layer 15B. Figure 21 In the described example, both the cutting of the metal layer 15 and the cutting of the second metal layer 15B are performed in a state where both the base portion 11 and the second base portion 11B are attached to the chuck body 31 .

[0110] like Figure 21 As illustrated, the method for manufacturing the chuck jaws in the first embodiment may also include rotating the metal layer 15 and the second metal layer 15B together with the chuck body 31 around the first axis AX, and repeatedly bringing the cutting tool T into contact with the metal layer 15 and the second metal layer 15B rotating around the first axis AX. Figure 21 In the example described, the surface of the metal layer 15 and the surface of the second metal layer 15B are smoothed in parallel using the turning tool T1. In other words, the metal layer 15 and the second metal layer 15B are turned substantially simultaneously using the turning tool T1.

[0111] In addition, if Figure 23 As illustrated, the method for manufacturing the chuck jaws in the first embodiment may include forming the grooves 161 on the surface of the metal layer 15 and forming the grooves 161 on the surface of the second metal layer 15B. Figure 23 In the described example, the grooves 161 are formed on the surface of the metal layer 15 and the grooves 161 are formed on the surface of the second metal layer 15B while both the base 11 and the second base 11B are attached to the chuck body 31 .

[0112] (Workpiece processing method) The workpiece machining method of the first embodiment includes a step of manufacturing the first chuck jaws 1A, a step of attaching the workpiece W to the plurality of chuck jaws 1, and a step of machining the workpiece. The workpiece machining step includes, for example, at least one of a third cutting step (described later), an additive manufacturing step (described later), a fourth cutting step (described later), a second additive manufacturing step (described later), and a fifth cutting step (described later).

[0113] The process of manufacturing the first chuck jaw 1A includes: (1) Figure 16 and Figure 17 As illustrated, the base 11 of the first block BL1 having the base 11 and the claw body 13 is mounted to the chuck body 31 rotatable about the first axis AX; and (2) as Figure 19 and Figure 20 As illustrated, the metal layer 15 is added to the claw body 13 in a state where the base 11 is attached to the chuck body 31 .

[0114] The first metal material G1 constituting the metal layer 15 has a lower thermal conductivity than the second metal material constituting the jaw body 13. The process for manufacturing the first chuck jaw 1A may include the first mounting step (first step ST1), the first cutting step (second step ST2), the first attaching step (third step ST3), the second cutting step (fourth step ST4), the disassembly step (fifth step ST5), and the first transfer step (sixth step ST6). Since steps 1 to 6 ST6 have already been described, their repeated description will be omitted.

[0115] Additionally, the workpiece machining method of the first embodiment may also include a step of manufacturing the second chuck jaw 1B and / or a step of manufacturing the third chuck jaw 1C. The steps of manufacturing the second chuck jaw 1B and the third chuck jaw 1C are the same as the steps of manufacturing the first chuck jaw 1A, and therefore, descriptions of the steps of manufacturing the second chuck jaw 1B and the third chuck jaw 1C are omitted.

[0116] After the process of manufacturing the first chuck jaw 1A (more specifically, after the process of manufacturing the first chuck jaw 1A, the process of manufacturing the second chuck jaw 1B, and the process of manufacturing the third chuck jaw 1C) is performed, in the seventh step ST7, the first chuck jaw 1A is transferred from the stocker 101 to the chuck body 31. The seventh step ST7 is a second transfer process.

[0117] exist Figure 27 In the example described above, the second transfer step (seventh step ST7) includes transferring the first chuck jaws 1A from the stocker 101 to the chuck body 31. Figure 27 In the described example, the second transfer step is automatically performed using the claw replacement device 102. Alternatively, the second transfer step may be performed manually.

[0118] like Figure 28As shown in the example, in the eighth step ST8, the first chuck jaw 1A (more specifically, the base 11 of the first chuck jaw 1A) is mounted to the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31). The eighth step ST8 is the second mounting process. Figure 28 In the described example, the second mounting step is automatically performed using the claw replacement device 102. Alternatively, the second mounting step may be performed manually.

[0119] Furthermore, if the above-described disassembly step (fifth step ST5) and the above-described first transfer step (sixth step ST6) are omitted, the second transfer step (seventh step ST7) and the second mounting step (eighth step ST8) are omitted. In this case, after the first chuck jaw 1A is manufactured, the first chuck jaw 1A is constantly held by the chuck body 31 until the workpiece W is gripped by the plurality of chuck jaws 1 including the first chuck jaw 1A.

[0120] Additionally, the workpiece machining method in the first embodiment may also include mounting the second base portion 11B of the second chuck jaw 1B to the chuck body 31 , and mounting the third base portion 11C of the third chuck jaw 1C to the chuck body 31 .

[0121] In the ninth step ST9, the workpiece W is mounted on the plurality of chuck jaws 1 including the first chuck jaw 1A. The ninth step ST9 is a workpiece mounting step.

[0122] like Figure 29 As illustrated, the workpiece mounting step (ninth step ST9 ) includes relatively moving the plurality of chuck jaws 1 relative to the base portion 33 of the chuck body 31 so that the workpiece W contacts the metal layer 15 (see arrow AR1 ). This relative movement is performed using the jaw driving device 34 .

[0123] like Figure 30 As illustrated, in the tenth step ST10, the workpiece W gripped by the plurality of chuck jaws 1 is cut. The tenth step ST10 is a cutting step (hereinafter referred to as a "third cutting step").

[0124] like Figure 30 As illustrated, the third cutting step (the tenth step ST10) may also include cutting the outer peripheral surface Wa of the workpiece W. Alternatively or additionally, the third cutting step (the tenth step ST10) may also include cutting the second end surface Wd of the workpiece W. If the workpiece W has a cylindrical shape, the third cutting step (the tenth step ST10) may also include cutting the inner peripheral surface of the workpiece W.

[0125] The third cutting step (the tenth step ST10 ) may include turning the workpiece W, or may include milling the workpiece W.

[0126] The third cutting step is a cutting step performed before the additive manufacturing step (the twelfth step ST12 ) described later. The third cutting step (the tenth step ST10 ) may be omitted.

[0127] like Figure 31 As illustrated, in the eleventh step ST11, the workpiece W gripped by the plurality of chuck jaws 1 is preheated. The eleventh step ST11 is a preheating step.

[0128] exist Figure 31 In the described example, the preheating step (eleventh step ST11) includes heating the workpiece W by irradiating the workpiece W with the laser beam LB. Alternatively or additionally, the preheating step (eleventh step ST11) may include heating the workpiece W by passing an induced current through the workpiece W, heating the workpiece W by radiating a flame toward the workpiece W, or heating the workpiece W using a heater.

[0129] The preheating step (eleventh step ST11) is performed while the metal layer 15 of the first chuck jaw 1A is in contact with the workpiece W. Because the thermal conductivity of the metal layer 15 is lower than that of the jaw body 13, the heat dissipation from the workpiece W to the first chuck jaw 1A during the preheating step can be minimized. Consequently, the energy required to preheat the workpiece W is reduced, reducing the environmental impact.

[0130] When the preheating step (eleventh step ST11) is performed by irradiation with laser light LB, the workpiece W may be irradiated with laser light LB so that the spot diameter of the laser light LB on the workpiece surface during the preheating step is larger than the spot diameter of the laser light LB on the workpiece surface during the additive manufacturing step (twelfth step ST12) described later. By making the spot diameter of the laser light LB during preheating relatively large, local melting of the workpiece W during preheating can be prevented or suppressed.

[0131] The preheating step (eleventh step ST11) may be omitted if the workpiece W is preheated before being held by the plurality of chuck jaws 1. Furthermore, if the preheating step (eleventh step ST11) is deemed unnecessary based on the size, shape, and material of the workpiece W, as well as the material of the material added to the workpiece W in the twelfth step ST12 described later, the preheating step (eleventh step ST11) may be omitted.

[0132] like Figure 32 As illustrated, in the twelfth step ST12 , the third material G3 is added to the workpiece W gripped by the plurality of chuck jaws 1 . The twelfth step ST12 is an additive manufacturing process, which is performed using the additive manufacturing apparatus 50 .

[0133] The additive manufacturing process (twelfth step ST12) is performed while the metal layer 15 of the first chuck jaw 1A is in contact with the workpiece W. Because the thermal conductivity of the metal layer 15 is lower than that of the jaw body 13, heat dissipation from the workpiece W to the first chuck jaw 1A can be suppressed during the additive manufacturing process, thereby minimizing a decrease in the temperature of the workpiece W. This prevents or minimizes material attachment defects (more specifically, damage to the material attached to the workpiece W). During the additive manufacturing process (twelfth step ST12), the entire portion of the first chuck jaw 1A in contact with the workpiece W is preferably composed of the metal layer 15. By preventing portions of the first chuck jaw 1A excluding the metal layer 15 from contacting the workpiece W, heat dissipation from the workpiece W to the first chuck jaw 1A can be more effectively suppressed.

[0134] exist Figure 32 In the example described, the additive manufacturing apparatus 50 supplies the third material G3 (more specifically, a powder of the third material g3) to the workpiece W and irradiates the workpiece W with laser light LB. As a result, the third material, heated by the energy of the laser light LB, melts, and the molten material adheres to the workpiece W. In this manner, the third material G3 is added to the workpiece W.

[0135] The third material G3 may be the same material as the first metal material G1 constituting the metal layer 15. In this case, there is no need to change the settings of the material supply system of the additive manufacturing apparatus 50 between the steps of manufacturing the chuck jaws and machining the workpiece.

[0136] Alternatively, the third material G3 may be a material different from the first metal material G1 constituting the metal layer 15. In this case, the options for the third material G3 increase. The third material G3 may be a metal material or a non-metal material.

[0137] like Figure 33 As illustrated, in the thirteenth step ST13, the workpiece W gripped by the plurality of chuck jaws 1 is cut. The thirteenth step ST13 is a cutting step (hereinafter referred to as a "fourth cutting step").

[0138] The fourth cutting step (the thirteenth step ST13) may also include cutting the outer peripheral surface Wa of the workpiece W. Alternatively or additionally, the fourth cutting step (the thirteenth step ST13) may also include cutting the second end surface Wd of the workpiece W. When the workpiece W has a cylindrical shape, the fourth cutting step (the thirteenth step ST13) may also include cutting the inner peripheral surface of the workpiece W.

[0139] The fourth cutting process (the thirteenth step ST13) may include turning the workpiece W, or may include milling the workpiece W. The fourth cutting process (the thirteenth step ST13) may also include cutting the original portion Wp of the workpiece W. Alternatively or additionally, Figure 33 As illustrated, the fourth cutting step (the thirteenth step ST13 ) may include cutting the additional portion Wq added to the original portion Wp of the workpiece by performing the additive manufacturing step.

[0140] The fourth cutting step is a cutting step performed after the aforementioned additive manufacturing step (the twelfth step ST12 ). The fourth cutting step (the thirteenth step ST13 ) may be omitted.

[0141] exist Figure 34 In the example described, the hybrid machine tool has a first support device 3 and a second support device 4. The first support device 3 includes a chuck body 31 to which multiple chuck jaws 1 are mounted. The second support device 4 includes a second chuck body 41 to which multiple chuck jaws are mounted. To distinguish the multiple chuck jaws mounted on the second chuck body 41 from the multiple chuck jaws 1 mounted on the chuck body 31, the former are referred to as the second set of chuck jaws 1S. In other words, the second set of chuck jaws 1S is mounted on the second chuck body 41.

[0142] like Figure 34 As illustrated, in step 14 ST14, the workpiece W is transferred from the first support device 3 to the second support device 4. Step 14 ST14 is a transfer process. The transfer process can also be automatically performed using the first support device 3 and the second support device 4. Alternatively, part of the transfer process can be performed using a transfer device other than the first support device 3 and the second support device 4 (e.g., a gantry loader, a workpiece changer, etc.), or can be performed manually.

[0143] exist Figure 34 In the example described, the transfer process (the fourteenth step ST14) includes moving the second set of chuck jaws 1S in a direction close to the workpiece W (see arrow AR2). By this movement, the workpiece W is gripped by the second set of chuck jaws 1S. Figure 34 In the example described, the transfer step (fourteenth step ST14 ) includes moving the plurality of chuck jaws 1 , including the first chuck jaw 1A, away from the workpiece W (see arrow AR3 ). This movement releases the grip of the plurality of chuck jaws 1 on the workpiece W.

[0144] exist Figure 34 In the described example, the transfer step (fourteenth step ST14 ) includes moving the second support device 4 relative to the first support device 3 in a direction parallel to the first axis AX (see arrow AR4 ) so as to increase the distance between the workpiece W and the first support device 3 .

[0145] like Figure 35As illustrated, in step 15 ST15, a fourth material G4 is added to the workpiece W gripped by the second set of chuck jaws 1S. Step 15 ST15 is a second additive manufacturing process. The second additive manufacturing process is performed using the additive manufacturing apparatus 50. The fourth material G4 may be the same as or different from the third material G3.

[0146] The second additive manufacturing process is performed with the workpiece W being gripped by the second set of chuck jaws 1S (fifteenth step ST15). Figure 35 In the example described, each chuck jaw of the second set of chuck jaws 1S includes a base 11s attached to the second chuck body 41, a jaw body 13s, and a metal layer 15s attached to the jaw body 13s and in contact with the workpiece W. The jaw body 13s is preferably made of the same material as the second metal material that constitutes the jaw body 13 of the first chuck jaw 1A. Furthermore, the metal layer 15s is preferably made of the same material as the first metal material that constitutes the metal layer 15 of the first chuck jaw 1A. In this case, since the thermal conductivity of the metal layer 15s is lower than that of the jaw body 13s, heat dissipation from the workpiece W to the chuck jaws 1S of the second set can be suppressed during the second additive manufacturing step. Furthermore, a decrease in the temperature of the workpiece W can be suppressed. This prevents or suppresses material addition defects (more specifically, damage to the material added to the workpiece W). Furthermore, if the second additive manufacturing step (fifteenth step ST15) is omitted, the metal layer 15s can be omitted from the chuck jaws 1S of the second set. In other words, the chuck jaws included in the second set of chuck jaws 1S may be formed of general chuck jaws.

[0147] After executing the fourteenth step ST14 (transfer process) and before executing the fifteenth step ST15 (second additive manufacturing process), the workpiece W may be preheated using a preheating device. If preheating is deemed unnecessary based on factors such as the temperature of the workpiece W, the shape of the workpiece W, the material of the workpiece W, and the material of the fourth material G4 added to the workpiece W in the fifteenth step ST15, this preheating may be omitted.

[0148] like Figure 36 As illustrated, in the sixteenth step ST16, the workpiece W gripped by the second set of chuck jaws 1S is cut. The sixteenth step ST16 is a cutting step (hereinafter referred to as a "fifth cutting step").

[0149] The fifth cutting step (step 16 ST16) may also include cutting the outer peripheral surface Wa of the workpiece W. Alternatively or additionally, the fifth cutting step (step 16 ST16) may also include cutting the first end surface Wb of the workpiece W. If the workpiece W has a cylindrical shape, the fifth cutting step (step 16 ST16) may also include cutting the inner peripheral surface of the workpiece W.

[0150] The fifth cutting process (the sixteenth step ST16) may include turning the workpiece W or milling the workpiece W. The fifth cutting process (the sixteenth step ST16) may also include cutting the original portion Wp of the workpiece W. Alternatively or additionally, the fifth cutting process (the sixteenth step ST16) may also include cutting the second added portion Wr added to the original portion Wp of the workpiece by performing the second additive manufacturing process.

[0151] The fifth cutting step may be performed after the second additive manufacturing step (fifteenth step ST15) or before the second additive manufacturing step (fifteenth step ST15). In addition, the fifth cutting step (sixteenth step ST16) may be omitted.

[0152] The above-mentioned transfer step (fourteenth step ST14 ), the above-mentioned second additive manufacturing step (fifteenth step ST15 ), and the above-mentioned fifth cutting step (sixteenth step ST16 ) may all be omitted.

[0153] (Chuck jaw repair method) Next, the chuck jaw repair method of the first embodiment will be described. The chuck jaw repaired in the chuck jaw repair method of the first embodiment is, for example, the first chuck jaw 1A of the first embodiment. The first chuck jaw 1A has already been described, so repeated description thereof will be omitted.

[0154] like Figure 37 As illustrated, in the seventeenth step ST17, the base surface 17 is formed on the first chuck jaw 1A. The seventeenth step ST17 is a base surface forming step.

[0155] The base surface forming step (the seventeenth step ST17) includes forming the base surface 17 by cutting at least a portion of the metal layer 15. Figure 37 In the example described, the base surface forming step (the seventeenth step ST17) includes forming the base surface 17-1 in the metal layer 15 of the chuck jaw 1 by cutting a portion of the metal layer 15. Alternatively, Figure 38 As illustrated, the base surface forming step (the seventeenth step ST17 ) may include forming the base surface 17 - 2 on the jaw body 13 of the chuck jaw 1 by cutting away the entire metal layer 15 .

[0156] exist Figure 37 、 Figure 38 In the described example, the step of forming the base surface 17 on the first chuck jaw 1A is performed with the base portion 11 of the first chuck jaw 1A attached to the chuck body 31 (more specifically, the movable portion 32 of the chuck body 31 ).

[0157] like Figure 39 As illustrated, in the eighteenth step ST18, the metal layer 15 is formed again. The eighteenth step ST18 is a forming step.

[0158] The re-forming process includes adding the first metal material G1 to the base surface 17 (e.g., Figure 37 As shown in the example, the base surface 17-1 formed on the metal layer 15, or Figure 38 As shown in the example, the metal layer 15 is formed again on the base surface 17-2 formed on the claw body 13. The first metal material is added to the base surface 17 using a metal adding device 5 (for example, an additive manufacturing device 50 or a spraying device).

[0159] like Figure 40 As illustrated, in the nineteenth step ST19, the surface of the metal layer 15 is cut. The nineteenth step ST19 is the sixth cutting step. The sixth cutting step includes cutting the metal layer 15 to smooth the surface 16 of the re-formed metal layer 15. By cutting the metal layer 15, the surface of the metal layer 15 becomes a smooth cut surface 16s.

[0160] Additionally, the sixth cutting process (nineteenth step ST19) may also include forming a groove 161 on the surface 16 of the metal layer 15. For example, the sixth cutting process (nineteenth step ST19) may also include forming a groove 161 on the surface 16 of the metal layer 15 by using a cutting tool such as a grooving tool T3 (if necessary, refer to FIG. Figure 23 ) contacts the metal layer 15 rotated around the first axis AX and forms a groove 161 on the surface of the metal layer 15.

[0161] The first chuck jaws 1A are repaired through the above steps. Since the used first chuck jaws 1A are repaired and reused, the frequency of discarding the chuck jaws is reduced, thereby reducing the environmental impact.

[0162] (Second embodiment) Reference Figures 1 to 44 A hybrid machine tool 100 according to the second embodiment will be described. Figure 44 1 is a diagram schematically showing a hybrid machine tool 100 according to a second embodiment.

[0163] like Figure 44As illustrated, the hybrid machine tool 100 in the second embodiment includes an additive manufacturing device 50 , a cutting device 60 , a first support device 3 , a first moving device 7 , a second moving device 8 , and a control device 9 .

[0164] The additive manufacturing device 50 and the cutting processing device 60 can be mounted on the first block BL1 (for example, see Figure 17 ) Manufacturing the first chuck jaw 1A (for example, referring to Figure 24 ). In addition, the additive manufacturing apparatus 50 and the cutting processing apparatus 60 can process the workpiece W gripped by the plurality of chuck jaws 1 including the first chuck jaw 1A.

[0165] like Figure 20 As shown in the example, the additive manufacturing device 50 includes a material supply device 55 and a first head 52 for emitting a laser beam LB. Figure 21 As illustrated, the cutting processing device 60 includes a second head 62 that supports a tool.

[0166] The first support device 3 supports the workpiece W via a plurality of chuck jaws 1 including a first chuck jaw 1A. The first chuck jaw 1A and the plurality of chuck jaws 1 have already been described in the first embodiment, and therefore, their repeated description will be omitted.

[0167] like Figure 12 As shown, the first support device 3 includes a chuck body 31 to which the base of the first chuck jaw 1A is mounted. In addition to the base of the first chuck jaw 1A, the chuck body 31 also includes a second base 11B of the second chuck jaw 1B and a third base 11C of the third chuck jaw 1C. The chuck body 31 is rotatable about a first axis AX.

[0168] like Figure 29 As illustrated, the first support device 3 includes a jaw driving device 34 for moving the chuck jaws 1 and a first rotation driving device 36 .

[0169] The jaw driving device 34 moves the plurality of chuck jaws 1 in a first direction DR1 away from the first axis AX (more specifically, in a radial direction away from the first axis AX) or in a second direction DR2 close to the first axis AX.

[0170] The first rotational drive device 36 rotates the chuck body 31 about the first axis AX. The first rotational drive device 36 can rotate the chuck body 31 and the plurality of chuck jaws 1 supported by the chuck body 31 integrally about the first axis AX. Furthermore, the first rotational drive device 36 can rotate the chuck body 31, the plurality of chuck jaws 1 supported by the chuck body 31, and the workpiece W gripped by the plurality of chuck jaws 1 integrally about the first axis AX.

[0171] exist Figure 44In the example described, the first moving device 7 moves the first head 52 relative to the first supporting device 3. The first moving device 7 includes a first head moving device 70 that moves the first head 52.

[0172] exist Figure 44 In the example described, the first head moving device 70 includes a first drive device 71 that moves the first head 52 in a direction parallel to the first axis AX, and a second drive device 72 that moves the first head 52 in a direction perpendicular to the first axis AX (e.g., a vertical direction). The first head moving device 70 may also include a device that can move the first head 52 three-dimensionally. The first head moving device 70 may also include a tilting device 73 that tilts the first head 52.

[0173] exist Figure 44 In the example described, the second moving device 8 moves the second head 62 relative to the first supporting device 3. The second moving device 8 includes a second head moving device 80 that moves the second head 62.

[0174] exist Figure 44 In the example described, the second head moving device 80 includes a third drive device 81 that moves the second head 62 in a direction parallel to the first axis AX, and a fourth drive device 82 that moves the second head 62 in a direction perpendicular to the first axis AX (e.g., a vertical direction). The second head moving device 80 may also include a device that can move the second head 62 three-dimensionally.

[0175] The second moving device 8 may also be a device completely independent of the first moving device 7. Alternatively, a part of the second moving device 8 and a part of the first moving device 7 may also be shared.

[0176] The control device 9 controls at least the additive manufacturing device 50 , the cutting device 60 , the first supporting device 3 , the first moving device 7 , and the second moving device 8 .

[0177] (Control device 9) The control device 9 is described in more detail. Figure 18 As shown, the control device 9 includes a hardware processor 90 (hereinafter referred to as "processor 90"), a memory 92, a communication circuit 94, and an input device 96 (e.g., a display 962 with a touch panel). The processor 90, the memory 92, the communication circuit 94, and the input device 96 are interconnected via a bus 98.

[0178] The memory 92 is a storage medium readable by the processor 90 of the control device 9. The memory 92 may be, for example, a nonvolatile or volatile semiconductor memory such as RAM, ROM, or flash memory, or a magnetic disk or other form of memory.

[0179] The memory 92 stores data 926 (eg, data required for the control device 9 to execute each mode described later) and programs 922 (eg, a claw manufacturing program 922a, a machining program 922b, and a claw replacement program 922c).

[0180] The data 926 stored in the memory 92 may include block shape data 926 a indicating the shape of the first block BL1 , jaw shape data 926 b indicating the shape of the first chuck jaw 1A, and workpiece shape data 926 c indicating the shape of the workpiece W.

[0181] The data 926 stored in the memory 92 may also include first control data 926d required for executing the jaw manufacturing mode M1 described later. The first control data 926d may also include first movement path data that specifies the movement path of the first head 52 and second movement path data that specifies the movement path of the cutting tool T. The first control data 926d may also include data specifying the rotation angle of the chuck body 31 about the first axis AX and / or data specifying the rotation speed of the chuck body 31 about the first axis AX.

[0182] The data 926 stored in the memory 92 may also include second control data 926e required for executing the preheating mode M5, described later. The second control data 926e may also include threshold data for determining whether preheating of the workpiece W is complete (e.g., first temperature TH1, first threshold TH2, and first time TH3, described later). Furthermore, the second control data 926e may also include laser output parameters. The second control data 926e may also include third movement path data defining the movement path of the first head 52 and / or data specifying the rotational speed of the chuck body 31 about the first axis AX.

[0183] The data 926 stored in the memory 92 may also include third control data 926f required for executing the additive manufacturing mode M6 described later. The third control data 926f may also include fourth movement path data that determines the movement path of the first head 52. The third control data 926f may also include data specifying the rotation angle of the chuck body 31 about the first axis AX and / or data specifying the rotation speed of the chuck body 31 about the first axis AX.

[0184] The data 926 stored in the memory 92 may also include fourth control data 926g required for executing the cutting processing mode M7 described later. The fourth control data 926g may also include fifth movement path data that determines the movement path of the cutting tool T. The fourth control data 926g may also include data specifying the rotation angle of the chuck body 31 around the first axis AX and / or data specifying the rotation speed of the chuck body 31 around the first axis AX.

[0185] The memory 92 may also store other data 926h.

[0186] The input device 96 is not limited to the display 962 with a touch panel. For example, the control device 9 may include input devices 96 such as buttons, switches, joysticks, pointing devices, and keyboards, as well as a display that displays data or other information input to the input devices 96. Furthermore, multiple computers may collaborate to function as the control device 9. Furthermore, the memory 92 may be distributed across multiple locations. For example, a portion of the memory 92 may be stored in cloud storage.

[0187] The control device 9 generates control instructions by executing programs 922 stored in the memory 92 (e.g., the claw manufacturing program 922a, the machining program 922b, and the claw replacement program 922c). The communication circuit 94 transmits these control instructions to the controlled devices (e.g., the additive manufacturing apparatus 50, the cutting and machining apparatus 60, the first support device 3, the first movable device 7, and the second movable device 8). Thus, by executing the programs 922 on the processor 90, the control device 9 can control the additive manufacturing apparatus 50, the cutting and machining apparatus 60, the first support device 3, the first movable device 7, and the second movable device 8.

[0188] The claw manufacturing mode M1 and the additive manufacturing mode M6 executable by the control device 9 will be described.

[0189] exist Figure 20 、 Figure 21 In the example described, the control device 9 can execute the claw manufacturing mode M1 by executing the program 922 (more specifically, the claw manufacturing program 922 a ). The claw manufacturing mode M1 is performed in a state where the base 11 is attached to the chuck body 31 .

[0190] like Figure 20 As illustrated, the claw manufacturing mode M1 includes using the additive manufacturing apparatus 50 to add a metal layer 15 composed of a first metal material G1 having lower thermal conductivity than the second metal material to the claw body 13 composed of a second metal material.

[0191] More specifically, claw manufacturing mode M1 involves sending a control command from the control device 9 to at least the first moving device 7 and the additive manufacturing device 50 to attach a metal layer 15 composed of a first metal material G1 having a lower thermal conductivity than the second metal material to the claw body 13. The first moving device 7, receiving the control command from the control device 9, moves the first head 52 to a position opposite the claw body 13. Furthermore, the additive manufacturing device 50, receiving the control command from the control device 9, attaches the metal layer 15 to the claw body 13.

[0192] like Figure 21As illustrated, the claw manufacturing mode M1 includes smoothing the surface of the metal layer 15 by cutting the metal layer 15 using the cutting processing device 60 .

[0193] More specifically, the claw manufacturing mode M1 includes sending a control command to at least the second moving device 8 to cut the metal layer 15 with the cutting tool T. The second moving device 8, receiving the control command from the control device 9, moves the second head 62 so that the cutting tool T comes into contact with the metal layer 15. The contact between the cutting tool T and the metal layer 15 causes the metal layer 15 to be cut, and the surface of the metal layer 15 becomes smooth.

[0194] exist Figure 32 In the example described, the control device 9 can execute the additive manufacturing mode M6 by executing the program 922 (more specifically, the machining program 922b). The additive manufacturing mode M6 is performed while the workpiece W is gripped by the plurality of chuck jaws 1 including the first chuck jaw 1A.

[0195] like Figure 32 As illustrated, the additive manufacturing mode M6 includes using the additive manufacturing device 50 to add the third material G3 to the workpiece W in contact with the metal layer 15 of the first chuck jaw 1A.

[0196] More specifically, the additive manufacturing mode M6 includes sending a control command to at least the first moving device 7 and the additive manufacturing device 50 to add the third material G3 to the workpiece W while the workpiece W is in contact with the metal layer 15 of the first chuck jaw 1A. The first moving device 7, receiving the control command from the control device 9, moves the first head 52 to a position opposite the workpiece W. Furthermore, the additive manufacturing device 50, receiving the control command from the control device 9, adds the third material G3 to the workpiece W. The third material G3 may be the same as or different from the first metal material G1 constituting the metal layer 15.

[0197] The hybrid machine tool 100 in the second embodiment can execute a jaw manufacturing mode M1, which involves attaching a metal layer 15 having a lower thermal conductivity than the jaw body 13 to the jaw body 13, and an additive manufacturing mode M6, which involves attaching a third material to the workpiece W while the workpiece W is in contact with the metal layer 15. Therefore, during additive manufacturing, in which the third material G3 is attached to the workpiece W, heat dissipation from the workpiece W to the first chuck jaw 1A can be suppressed, thereby minimizing a decrease in the temperature of the workpiece W. This prevents or minimizes improper attachment of the material to the workpiece W (more specifically, damage to the attached material).

[0198] (Optional additional structure) Next, refer to Figures 1 to 44Any additional structure that can be adopted in the hybrid machine tool 100 in the second embodiment (or the chuck jaw 1 in the first embodiment, the manufacturing method of the chuck jaw in the first embodiment, the workpiece processing method in the first embodiment, and the repair method of the chuck jaw in the first embodiment) is described.

[0199] (Claw Manufacturing Mode M1) An example of the claw manufacturing mode M1 will be described in more detail. The control device 9 executes the claw manufacturing mode M1 by executing the program 922 (more specifically, the claw manufacturing program 922a).

Additionally, the claw manufacturing mode M1 may also include sending a rotation instruction (hereinafter referred to as the "second rotation instruction U2") from the control device 9 to the first rotation drive device 36.

[0206] The first moving device 7, which receives the second movement instruction Q2 from the control device 9, moves the first head 52 to a position opposite the base surface 130. The additive manufacturing device 50, which receives the first additive manufacturing instruction D1 from the control device 9, adds the metal layer 15 to the base surface 130 (more specifically, adds the metal layer 15 to the first base surface 131 and the second base surface 132).

[0207] When the second rotation command U2 is sent from the control device 9 to the first rotation drive device 36, the first rotation drive device 36 rotates the claw body 13 about the first axis AX. In this case, the metal layer 15 can be attached to the base surface 130 without significantly moving the first head 52.

[0209] More specifically, the claw manufacturing mode M1 includes sending a movement instruction (hereinafter referred to as the "third movement instruction Q3") from the control device 9 to the second moving device 8, and sending a rotation instruction (hereinafter referred to as the "third rotation instruction U3") from the control device 9 to the first rotation drive device 36 to smooth the surface of the metal layer 15 (more specifically, to form a first cutting surface 16s-1 extending in a direction parallel to the first axis AX and a second cutting surface 16s-2 perpendicular to the first axis AX on the metal layer 15).

[0210] The second moving device 8, receiving the third movement command Q3 from the control device 9, moves the second head 62 so that the turning tool T1 contacts the metal layer 15. The first rotation drive device 36, receiving the third rotation command U3 from the control device 9, rotates the claw body 13, to which the metal layer 15 is attached, about the first axis AX.

The first rotation drive device 36, receiving the fourth rotation command U4 from the control device 9, rotates the claw body 13, to which the metal layer 15 is attached, about the first axis AX. In this manner, the grooving tool T3 cuts the metal layer 15, forming a groove 161 on the surface of the metal layer 15.

Figure 25 As illustrated, the disassembly mode M2 includes sending a disassembly command F1 from the control device 9 to the jaw changing device 102 to disassemble the first chuck jaw 1A located at the disassembly position P1 from the chuck body 31 .

[0220] exist Figure 24 In the example described, the first rotation drive device 36 receives the fifth rotation instruction U5 and rotates the chuck body 31 about the first axis AX to move the first chuck jaw 1A to the detachment position P1. Figure 24 In the example described, the jaw replacement device 102 receives the disassembly instruction F1 and presses the operation portion 39 to release the engagement between the first chuck jaw 1A and the chuck body 31. Figure 25 In the example described, the jaw changing device 102 receives the detachment command F1 and pulls the first chuck jaw 1A out of the chuck body 31. In this way, the first chuck jaw 1A is detached from the chuck body 31.

[0221] like Figure 26 As illustrated, the disassembly mode M2 may also include transferring the first chuck jaw 1A from the chuck body 31 to the stocker 101 using the jaw changing device 102 .

[0222] (Installation mode M3) exist Figure 28 In the described example, the control device 9 executes the program 922 (more specifically, the jaw replacement program 922 c ) to execute the mounting mode M3 for mounting the first chuck jaws 1A manufactured using the additive manufacturing apparatus 50 and the cutting apparatus 60 to the chuck body 31 .

[0223] like Figure 27 and Figure 28 As illustrated, the mounting mode M3 may also include transferring the first chuck jaw 1A from the stocker 101 to the chuck body 31 using the jaw changing device 102 .

[0224] like Figure 28 As illustrated, the mounting mode M3 includes mounting the first chuck jaw 1A to the chuck body 31 using the jaw changing device 102 .

[0225] More specifically, the mounting mode M3 includes sending a mounting instruction F2 from the control device 9 to the jaw changing device 102 to mount the first chuck jaw 1A to the chuck body 31 .

Furthermore, the jaw changing device 102, having received the installation command F2, inserts the first chuck jaw 1A into the chuck body 31. Furthermore, the jaw changing device 102, having received the installation command F2, releases the pressure on the operating portion 39 to move the engaging portion 312 of the chuck body 31 from the retracted position to the advanced position. In this manner, the first chuck jaw 1A is attached to the chuck body 31.

[0227] (Workpiece mounting mode M4) exist Figure 29 In the described example, the control device 9 executes the program 922 (more specifically, the machining program 922 b ) to execute the workpiece mounting mode M4 for mounting the workpiece W on the plurality of chuck jaws 1 .

[0228] like Figure 29 As illustrated, the workpiece mounting mode M4 includes mounting the workpiece W to the plurality of chuck jaws 1 using the jaw driving device 34 .

[0229] More specifically, if Figure 29 As illustrated, the workpiece mounting mode M4 includes sending a gripping command J1 from the control device 9 to the jaw driving device 34. Receiving the gripping command J1 from the control device 9, the jaw driving device 34 moves the movable portion 32 of the chuck body 31 in the first direction DR1 or the second direction DR2 so that the plurality of chuck jaws 1 grip the workpiece W. In this manner, the workpiece W is mounted on the plurality of chuck jaws 1.

[0230] (Preheating device 58) like Figure 31 As shown in the example, the hybrid machine tool 100 may also include a preheating device 58 for preheating the workpiece W. Figure 31 In the example described, the preheating device 58 includes a laser irradiation device 51 for irradiating the workpiece W with laser light LB to increase the temperature of the workpiece W. Figure 31 and Figure 32 In the example described, the laser irradiation device 51 serves as a preheating device 58 for preheating the workpiece W (see Figure 31 ) functions as an additive manufacturing device 50 (see Figure 32 ) part of the function.

[0231] Alternatively or additionally, the preheating device 58 may include a high-frequency induction heating device that heats the workpiece W by passing an induced current through the workpiece W. Alternatively or additionally, the preheating device 58 may include a heater such as a ceramic heater. Alternatively or additionally, the preheating device 58 may include a gas burner that radiates flame toward the workpiece W.

[0232] (Preheating mode M5) exist Figure 31 In the example described, the control device 9 executes the preheating mode M5 by executing the program 922 (more specifically, the machining program 922 b ). The preheating mode M5 is executed immediately before the additive manufacturing mode M6 . The preheating mode M5 includes preheating the workpiece W using the preheating device 58 .

[0233] More specifically, the preheating mode M5 includes sending a preheating command V1 from the control device 9 to at least the preheating device 58 to increase the temperature of the workpiece W. Additionally, the preheating mode M5 may also include sending at least one of a movement command (hereinafter referred to as the "fifth movement command Q5") from the control device 9 to the first movement device 7 and a rotation command (hereinafter referred to as the "sixth rotation command U6") from the control device 9 to the first rotation drive device 36.

[0234] The preheating device 58 receives the preheating instruction V1 from the control device 9 and adds energy to the workpiece W to increase the temperature of the workpiece W. Figure 31 In the example described, the laser irradiation device 51, receiving the preheating command V1, emits laser light LB toward the workpiece W. Furthermore, the first movement device 7, receiving the fifth movement command Q5, or the first rotation drive device 36, receiving the sixth rotation command U6, moves the first head 52 relative to the workpiece W gripped by the plurality of chuck jaws 1. In this manner, the laser light LB emitted from the first head 52 preheats the workpiece W. Furthermore, by moving the first head 52, which emits the laser light LB, relative to the workpiece W, the laser light LB is prevented from being concentrated on a specific area of the workpiece W.

[0235] like Figure 31 As illustrated, the hybrid machine tool 100 may also include a temperature sensor 56, such as an infrared temperature sensor. The temperature sensor 56 detects the temperature of the workpiece W. The temperature sensor 56 transmits signal data DA indicating the temperature of the workpiece W to the control device 9. Based on the signal data DA received from the temperature sensor 56, the control device 9 may cause the preheating device 58 to continue preheating the workpiece W until the temperature of the workpiece W reaches a predetermined first temperature TH1, and may transmit a preheating end instruction to the preheating device 58 in response to the temperature of the workpiece W reaching the predetermined first temperature TH1 (first example).

[0236] Alternatively, the control device 9 may also cause the preheating device 58 to continue preheating the workpiece W based on the signal data DA received from the temperature sensor 56 until the temperature rise of the workpiece W from the temperature of the workpiece W at the time of starting the preheating mode M5 (in other words, the value obtained by subtracting the temperature of the workpiece W at the time of starting the preheating mode M5 from the current temperature of the workpiece W) reaches a predetermined first threshold value TH2, and send a preheating end instruction to the preheating device 58 in response to the above-mentioned temperature rise reaching the first threshold value TH2 (second example).

[0237] Alternatively or additionally, the hybrid machine tool 100 may also include a timer 99. The timer 99 may be implemented as hardware, or the control device 9 may execute a program 922 to cause the control device 9 itself to function as a timer. The timer 99 measures the time elapsed since the control device 9 began sending a preheating instruction V1 to the preheating device 58. The control device 9 may also cause the preheating device 58 to continue preheating the workpiece W until the elapsed time measured by the timer 99 reaches a predetermined first time TH3, and may then send a preheating end instruction to the preheating device 58 in response to the elapsed time reaching the first time TH3 (third example).

[0238] In each of the first, second, and third examples, the preheating device 58 receiving the preheating command V1 adds energy to the workpiece W to increase the temperature of the workpiece W. Furthermore, the preheating device 58 receiving the preheating end command stops adding energy to the workpiece W to stop the temperature increase of the workpiece W.

[0239] (Additive manufacturing device 50) exist Figure 32 In the described example, the additive manufacturing apparatus 50 includes a material supply device 55 for supplying a third material G3 to be added to the workpiece W, and a laser irradiation device 51. The laser irradiation device 51 includes a first head 52 for emitting a laser beam LB.

[0240] The material supply device 55 may be a device that supplies a wire (e.g., a metal wire) to the workpiece W. In this case, the wire is melted by irradiating the laser beam LB, and the resulting melt adheres to the workpiece W. Alternatively, the material supply device 55 may be a device that supplies a powder (e.g., a metal powder) to the workpiece W. In this case, the powder is melted by irradiating the laser beam LB, and the resulting melt adheres to the workpiece W.

[0241] When the third material G3 is different from the first metal material G1, the material supply device 55 can preferably selectively supply the first metal material G1 and the third material G3. The hybrid machine tool 100 may include a first container for accommodating the first metal material G1 and a second container for accommodating the third material G3.

[0242] (Additive Manufacturing Mode M6) exist Figure 32 In the example described, the control device 9 executes the program 922 (more specifically, the machining program 922 b ) to execute the additive manufacturing mode M6 .

Additionally, additive manufacturing mode M6 may also include sending a rotation command (hereinafter referred to as "seventh rotation command U7") from the control device 9 to the first rotation drive device 36.

[0244] The first moving device 7 receiving the sixth movement instruction Q6 from the control device 9 moves the first head 52 to a position facing the workpiece W. The additive manufacturing device 50 receiving the second additive manufacturing instruction D2 from the control device 9 adds the third material G3 to the workpiece W.

[0245] When the seventh rotation command U7 is sent from the control device 9 to the first rotation drive device 36, the first rotation drive device 36 rotates the workpiece W about the first axis AX. In this case, the third material G3 can be added to the workpiece W without significantly moving the first head 52.

[0246] (Cutting Processing Device 60) The cutting device 60 has a second head 62. Figure 36 As shown in the example, the second head 62 may also include a motor 66 for rotating the milling tool T2 around the center axis of the milling tool.

[0247] The second head 62 may also be a turret. In this case, the second head 62 may be a turret head capable of supporting both the turning tool T1 and the milling tool T2. Alternatively, the turret head may be capable of simultaneously supporting the turning tool T1, the milling tool T2, and the grooving tool T3.

[0248] (Cutting mode M7) exist Figure 30 or Figure 33 In the example described, the control device 9 executes the program 922 (more specifically, the machining program 922 b ) to execute the cutting mode M7 . The cutting mode M7 includes cutting the workpiece W using the cutting device 60 .

[0249] More specifically, the cutting mode M7 includes sending a movement command (hereinafter referred to as the "seventh movement command Q7") from the control device 9 to the second movement device 8 to cut the workpiece W gripped by the plurality of chuck jaws 1 including the first chuck jaw 1A. Additionally, the cutting mode M7 may also include sending a rotation command (hereinafter referred to as the "eighth rotation command U8") from the control device 9 to the first rotation drive device 36.

[0250] The second moving device 8 receiving the seventh movement command Q7 from the control device 9 brings the turning tool T1 into contact with the workpiece W. The first rotation drive device 36 receiving the eighth rotation command U8 rotates the workpiece W about the first axis AX.

[0251] Alternatively, the cutting processing mode M7 may send a tool rotation command for rotating the milling tool T2 to the motor 66. The motor 66 receives the tool rotation command and rotates the milling tool T2 about the central axis of the milling tool T2. In this way, the workpiece W is cut by the milling tool T2.

[0252] (First Supporting Device 3) exist Figure 34 In the example described, the first support device 3 includes a housing 37 that supports the chuck body 31 rotatably about the first axis AX. The first support device 3 may include a moving device 35 that moves the housing 37. The moving device 35 can move the housing 37 in a direction parallel to the first axis AX, for example.
