[0044] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of the components and steps set forth in the embodiments, numerical expressions, and numerical values are not limiting to the scope of the present application unless specifically stated otherwise.

[0045] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application or its application or uses.

[0046] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, the techniques, methods, and devices should be considered part of the specification, if appropriate.

[0047] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0048] It should be noted that like reference numerals and characters refer to like items throughout the several views, and once an item is defined in one view, it should not have to be discussed further in subsequent views.

[0049] In a machining site, the tool shank types on different machine tables in a numerical control machine tool can be different. There are many types of tool shanks. Therefore, the pre-programmed program in the numerical control machine tool has certain limitations in the field use. For example, if a corresponding control program is programmed for each pre-specified tool, the efficiency of this way is low and lacks flexibility. The inventor notices that in the use of the numerical control machine tool, a part of the tool shank of the machining tool can be deeply inserted into the workpiece being machined. The tool shank insertion amount can be simulated by CAM (Computer Aided Manufacturing) programming to reduce the length of the tool clamping. By inserting the tool shank into the workpiece being machined, the machining quality can be ensured.

[0050] For example, the CNC machine tool performs high-cut-depth machining on the workpiece, and a longer tool can be used. When the tool length is too long, the tool will have overcutting problems due to inertia during machining. Therefore, in order to ensure the quality of the workpiece being machined, the tool shank can be used to simulate the insertion amount of the tool to reduce the length of the tool clamping.

[0051] Therefore, the tool shank insertion amount can be simulated based on the CAM programming. Since there are many types of tool shanks, the CAM program can pre-specify a tool shank to simulate the insertion amount of the tool shank. The CNC machine tool processes the workpiece using the same tool shank as in the program simulating the insertion amount of the tool shank.

[0052] In a machining site, the tool shank types on different machine tables in a numerical control machine tool can be different. There are many types of tool shanks. Therefore, the pre-programmed program in the numerical control machine tool has certain limitations in the field use. For example, if a corresponding control program is programmed for each pre-specified tool, the efficiency of this way is low and lacks flexibility. The inventor notices that in the use of the numerical control machine tool, a part of the tool shank of the machining tool can be deeply inserted into the workpiece being machined. The tool shank insertion amount can be simulated by CAM (Computer Aided Manufacturing) programming to reduce the length of the tool clamping. By inserting the tool shank into the workpiece being machined, the machining quality can be ensured.

[0053] The embodiments of the present application provide a tool shank matching determination method. Before the CNC machine tool executes the program simulating the tool shank insertion amount, it is determined whether the tool shank used in the field machining matches the tool shank simulated in the program.

[0054] In order to facilitate understanding, Figure 1 A structure diagram of a tool shank 100, a tool 120 clamped by the tool shank 100, and a part 140 of the tool shank 100 connected to a CNC machine tool spindle is provided.

[0055] As shown in the drawings, Figure 1 The tool shank 100 includes a tool shank conical part 101, a tool shank reinforcing part 102, and a tool shank end part 103.

[0056] The lower end of the tapered portion 101 of the tool holder is fitted with a tool 120. One end of the reinforcing portion 102 of the tool holder is connected to the tapered portion 101 of the tool holder, and the other end is connected to the end portion 103 of the tool holder. The top end of the end portion 103 of the tool holder is connected to the portion 140 that connects to the CNC machine tool spindle.

[0057] The length of the tool 120 clamped by the tool holder 100 (i.e., the tool clamping overhang) is H. The length of the tapered portion 101 of the tool holder is M. The tapered portion 101 of the tool holder has a certain taper. The taper is equal to the difference between the maximum diameter D2 and the minimum diameter D1 of the tapered portion 101 of the tool holder, divided by the length M of the tapered portion 101 of the tool holder. The taper is used to reflect the slope of the tapered portion 101 of the tool holder. The length of the reinforcing portion 102 of the tool holder is L1, and the diameter is D3. The length of the end portion 103 of the tool holder is L2, and the diameter is D4. The sum of the lengths of the end portion 103 of the tool holder, the reinforcing portion 102 of the tool holder, and the tapered portion 101 of the tool holder is L.

[0058] In this embodiment, the tool holder 100 can be a tool holder used for CAM simulation of tool holder insertion depth, or a tool holder used for CNC on-site machining. The model of the tool holder 100 is not limited; for example, it can be F63-SLRA4-75-M22 or F63-MEGA10N-75-M22. Here, F63 is the taper model; SLRA / MEGA is the manufacturer's tool holder model; 4 / 10N is the maximum clamping diameter (for heat-shrinkable types, it's the clampable diameter); N is the collet manufacturer's model; 75 is the tool holder length; and M22 is the taper length.

[0059] like Figure 2 As shown in the figure, this application embodiment provides a tool holder matching determination method, including the following steps S2100-S2300.

[0060] S2100: Obtain the depth of cut for machining the workpiece and the corresponding first tool holder.

[0061] The depth of cut is the depth to which the workpiece needs to be cut.

[0062] The first tool holder is the tool holder simulated in computer-aided manufacturing programming.

[0063] In some embodiments of this application, the depth of cut for machining the workpiece and the specific information of the corresponding first tool holder can be obtained from the program that simulates the probe depth of the first tool holder uploaded by CAM.

[0064] In one example, the model of the first tool holder can be obtained from the program simulating the first tool holder's stick-out uploaded to the CAM. According to the obtained model of the first tool holder, the information corresponding to the first tool holder is obtained from the database storing the tool holder information. For example, the length H of the first tool holder clamping the tool 120, the length M of the tool holder taper portion, the maximum diameter D2 of the tool holder taper portion, the minimum diameter D1 of the tool holder taper portion, the length L1 and diameter D3 of the tool holder reinforcing portion, the length L2 and diameter D4 of the tool holder end portion are obtained.

[0065] S2200, according to the stick-in part of the first tool holder, obtaining the length of the stick-in part of the second tool holder.

[0066] The stick-in part of the first tool holder is the part of the first tool holder that can stick into the workpiece. Those skilled in the art should understand that the part of the tool holder that can stick into the workpiece is the part of the tool holder that can stick into the workpiece under the condition that the tool holder can realize its tool function.

[0067] The stick-in part of the first tool holder can include the tool holder taper portion 101, or the tool holder taper portion 101 and the tool holder reinforcing portion 102, or the tool holder taper portion 101, the tool holder reinforcing portion 102 and the tool holder end portion 103.

[0068] Optionally, when the sum of the tool clamping overhang H of the first tool holder and the length M of the tool holder taper portion is greater than the depth of cut, the stick-in part of the first tool holder is the tool holder taper portion 101.

[0069] Optionally, when the sum of the tool clamping overhang H of the first tool holder and the length M of the tool holder taper portion is less than or equal to the depth of cut, and the sum of the tool clamping overhang H of the first tool holder, the length M of the tool holder taper portion and the length L1 of the tool holder reinforcing portion is greater than the depth of cut, the stick-in part of the first tool holder is the tool holder taper portion 101 and the tool holder reinforcing portion 102.

[0070] Optionally, when the sum of the tool clamping overhang H of the first tool holder, the length M of the tool holder taper portion and the length L1 of the tool holder reinforcing portion is less than or equal to the depth of cut, and the sum of the tool clamping overhang H of the first tool holder, the length M of the tool holder taper portion, the length L1 of the tool holder reinforcing portion and the length L2 of the tool holder end portion is greater than the depth of cut, the stick-in part of the first tool holder is the tool holder taper portion 101, the tool holder reinforcing portion 102 and the tool holder end portion 103.

[0071] Optionally, when the sum of the tool clamping overhang H of the first tool holder, the length M of the tool holder taper portion, the length L1 of the tool holder reinforcing portion and the length L2 of the tool holder end portion is less than or equal to the depth of cut, the stick-in part of the first tool holder is the tool holder taper portion 101, the tool holder reinforcing portion 102 and the tool holder end portion 103.

[0072] The second tool holder is a tool holder actually used in a computer numerical control machine tool. The second tool holder can be of the same model as the first tool holder, or can be of a different model.

[0073] The length of the second tool holder's insertion portion is the length of the portion of the second tool holder that can be inserted into the workpiece.

[0074] In embodiments of the present application, the information of the second tool holder is provided by the machine tool to which the second tool holder is bound. As an example, the electronic device executing the present method acquires the model of the second tool holder bound by the machine tool. When the second tool holder is of the same model as the first tool holder, the matching determination method terminates execution. When the second tool holder is of a different model than the first tool holder, the information of the second tool holder is acquired from the database storing tool holder information, for example, the length of the insertion portion of the second tool holder, according to the model.

[0075] The insertion portion of the second tool holder can include the tool holder taper portion 101, can include the tool holder taper portion 101 and the tool holder reinforcing portion 102, and can include the tool holder taper portion 101, the tool holder reinforcing portion 102, and the tool holder end portion 103.

[0076] It can be understood that when the insertion portion of the first tool holder is the tool holder taper portion 101, the information of the tool holder reinforcing portion 102 or the tool holder end portion 103 will not exist in the program corresponding to the simulated tool holder insertion amount. In this case, the sum of the length M of the tool holder taper portion 101 of the second tool holder and the overhang H of the tool holder clamping portion must satisfy the depth of cut requirement. At this time, the machine tool can control the second tool holder to machine the workpiece based on the simulation program of the first tool holder.

[0077] Similarly, when the insertion portion of the first tool holder is the tool holder taper portion 101 and the tool holder reinforcing portion 102, the information of the tool holder end portion 103 will not exist in the program corresponding to the simulated tool holder insertion amount. In this case, the sum of the length M of the tool holder taper portion 101 of the second tool holder, the length L1 of the tool holder reinforcing portion 102, and the overhang H of the tool holder clamping portion must satisfy the depth of cut requirement. Alternatively, the sum of the length M of the tool holder taper portion 101 of the second tool holder and the overhang H of the tool holder clamping portion already satisfies the depth of cut requirement. At this time, the machine tool can control the second tool holder to machine the workpiece based on the simulation program of the first tool holder.

[0078] Therefore, in some embodiments of the present application, when the insertion portion of the first tool holder includes a tool holder taper portion, the insertion portion of the second tool holder includes a tool holder taper portion.

[0079] In these embodiments, when the insertion portion of the first tool holder includes a tool holder taper portion, the length M of the tool holder taper portion of the second tool holder is acquired B .

[0080] In these embodiments, as Figure 3As shown, step S2200 includes steps S2210-S2230.

[0081] S2210, obtaining the minimum diameter D1 of the tapered portion of the first tool holder A and the minimum diameter D1 of the tapered portion of the second tool holder B .

[0082] S2220, in the case where the minimum diameter D1 of the tapered portion of the first tool holder A is greater than or equal to the minimum diameter D1 of the tapered portion of the second tool holder B , obtaining the maximum diameter D2 of the tapered portion of the first tool holder A and the maximum diameter D2 of the tapered portion of the second tool holder B .

[0083] That is, if the minimum diameter D1 of the tapered portion of the first tool holder A is greater than or equal to the minimum diameter D1 of the tapered portion of the second tool holder B , the next step is successfully entered, obtaining the maximum diameter D2 of the tapered portion of the first tool holder A and the maximum diameter D2 of the tapered portion of the second tool holder B . If the minimum diameter D1 of the tapered portion of the first tool holder A is less than the minimum diameter D1 of the tapered portion of the second tool holder B , the second tool holder and the first tool holder fail to match, and the method terminates. This can avoid interference between the second tool holder and the workpiece, reducing the risk of damage to the second tool holder or even the main shaft.

[0084] S2230, in the case where the maximum diameter D2 of the tapered portion of the first tool holder A is greater than or equal to the maximum diameter D2 of the tapered portion of the second tool holder B , obtaining the length M of the tapered portion of the second tool holder B .

[0085] That is, if the maximum diameter D2 of the tapered portion of the first tool holder A is greater than or equal to the maximum diameter D2 of the tapered portion of the second tool holder B , the next step is successfully entered, obtaining the length M of the tapered portion of the second tool holder B . If the maximum diameter D2 of the tapered portion of the first tool holder A is less than the maximum diameter D2 of the tapered portion of the second tool holder B , the second tool holder and the first tool holder fail to match, and the method terminates. This can avoid interference between the second tool holder and the workpiece, reducing the risk of damage to the second tool holder or even the main shaft.

[0086] In some other embodiments of this application, when the insertion portion of the first tool holder includes a tapered portion of the tool holder and a reinforcing portion of the tool holder, the insertion portion of the second tool holder may include a tapered portion of the tool holder, or it may include a tapered portion of the tool holder and a reinforcing portion of the tool holder.

[0087] Optionally, when the insertion portion of the first tool holder includes a tapered portion and a reinforcing portion, the length M of the tapered portion of the second tool holder is obtained. B At this time, when the length M of the tapered portion of the second tool holder... B When the probe volume requirement is met, the matching path is the shortest, which can save matching time.

[0088] Optionally, when the insertion portion of the first tool holder includes a tapered portion and a reinforcing portion, the sum M of the length of the tapered portion and the length of the reinforcing portion of the second tool holder is obtained. B +L1 B .

[0089] In these embodiments, when the insertion portion of the first tool holder includes a tapered portion and a reinforcing portion, the length M of the tapered portion of the second tool holder is first obtained. B When the length of the tapered section of the tool holder is insufficient to meet the probe depth requirement, the sum M of the length of the tapered section and the length of the reinforcing section of the tool holder is then obtained. B +L1 B .

[0090] In these embodiments, when the insertion portion of the second tool holder includes a tapered portion of the tool holder, step S2200 also includes steps S2210-S2230. Further details are omitted here.

[0091] In these embodiments, when the insertion portion of the second tool holder includes a tapered portion and a reinforcing portion, such as Figure 4 As shown, step S2200 further includes the following steps S2240-S2250.

[0092] S2240. Obtain the diameter of the reinforcing portion of the first tool holder and the diameter of the reinforcing portion of the second tool holder.

[0093] S2250, the diameter D3 of the reinforcing portion of the first tool holder A The diameter D3 of the reinforcing portion of the second tool holder is greater than or equal to the diameter of the second tool holder. B In the case of obtaining the length L1 of the reinforcing part of the second tool holder, B .

[0094] In other words, if the diameter D3 of the reinforcing part of the first tool holder... A The diameter D3 of the reinforcing portion of the second tool holder is greater than or equal to the diameter of the second tool holder. B, the second handle and the first handle are matched successfully, and the method proceeds to the next step B If the diameter D3 of the handle reinforcing portion of the first handle is smaller than the diameter D3 of the handle reinforcing portion of the second handle A , the diameter D3 of the handle reinforcing portion of the second handle is smaller than the diameter D3 of the handle reinforcing portion of the first handle B , the second handle and the first handle are matched unsuccessfully, and the method is terminated.

[0095] In some embodiments of the present application, the insertion portion of the first handle comprises a handle tapering portion, a handle reinforcing portion and a handle end portion, and the insertion portion of the second handle comprises a handle tapering portion.

[0096] Optionally, when the insertion portion of the first handle comprises a handle tapering portion, a handle reinforcing portion and a handle end portion, the length M of the handle tapering portion of the second handle is obtained B .

[0097] Optionally, when the insertion portion of the first handle comprises a handle tapering portion, a handle reinforcing portion and a handle end portion, the sum M of the length of the handle tapering portion and the length of the handle reinforcing portion of the second handle is obtained B +L1 B .

[0098] Optionally, when the insertion portion of the first handle comprises a handle tapering portion, a handle reinforcing portion and a handle end portion, the sum M of the length of the handle tapering portion, the length of the handle reinforcing portion and the length of the handle end portion of the second handle is obtained B +L1 B +L2 B .

[0099] In these embodiments, when the insertion portion of the first handle comprises a handle tapering portion, a handle reinforcing portion and a handle end portion, first, the length M of the handle tapering portion of the second handle is obtained B . When the length of the handle tapering portion is insufficient to meet the requirement of the insertion amount, the sum M of the length of the handle tapering portion and the length of the handle reinforcing portion is obtained B +L1 B . When the sum of the length of the handle tapering portion and the length of the handle reinforcing portion is still insufficient to meet the requirement of the insertion amount, the sum M of the length of the handle tapering portion, the length of the handle reinforcing portion and the length of the handle end portion of the second handle is obtained B +L1 B +L2 B .

[0100] In these embodiments, when the insertion portion of the second handle comprises a handle tapering portion, the step S2200 also comprises the following steps S2210-S2230. Details are not described herein.

[0101] In these embodiments, when the insertion portion of the second tool holder includes a tapered portion and a reinforcing portion, step S2200 also includes steps S2240-S2250 as follows. These will not be elaborated upon here.

[0102] In these embodiments, when the insertion portion of the second tool holder includes a tapered portion of the tool holder, a reinforcing portion of the tool holder, and an end portion of the tool holder, such as Figure 5 As shown, step S2200 further includes the following steps S2260-S2270.

[0103] S2260, Obtain the diameter D4 of the end of the first tool holder. A and the diameter D4 of the end of the second tool holder B .

[0104] S2270, the diameter D4 at the end of the first tool holder A The diameter D4 of the end of the second tool holder is greater than or equal to the diameter of the tool holder. B In the case of obtaining the length L2 of the end of the second tool holder. B .

[0105] In other words, if the diameter D4 of the end of the first tool holder A The diameter D4 of the end of the tool holder is greater than or equal to that of the second tool holder. B Successfully proceed to the next step: obtain the length L2 of the toolholder end of the second toolholder. B If the diameter D4 of the end of the first tool holder A The diameter D4 of the end of the tool holder is smaller than that of the second tool holder. B If the second tool holder fails to match the first tool holder, the method terminates.

[0106] S2300: If the sum of the length of the protruding part of the second tool holder and the overhang of the tool clamping part is greater than the depth of cut, determine that the second tool holder is matched with the first tool holder.

[0107] In some embodiments of this application, when the insertion portion of the first tool holder includes a tapered portion, the length M of the tapered portion of the second tool holder is obtained if the minimum diameter and the maximum diameter of the tapered portion of the second tool holder satisfy the condition. B .

[0108] It is understandable that when the insertion part of the first toolholder is a tapered section, the corresponding program simulating the toolholder insertion amount will not contain information about the toolholder reinforcement or the toolholder end. In this case, the sum H of the length of the tapered section of the second toolholder and the overhang of the tool clamping part is... B +M Bmust be greater than or equal to the depth of cut. At this time, the machine tool can control the second tool holder to machine the workpiece based on the simulation program of the first tool holder.

[0109] However, the machine tool usually has some errors in the process of machining the workpiece. For example, the expected depth of cut is 10 cm, but due to the machining precision, the actual depth of cut may be 10.1 cm. In this case, if the length of the tool holder taper portion of the second tool holder is equal to the depth of cut, the tool holder reinforcing portion of the second tool holder will be used for probing in the actual machining. Since the diameter of the tool holder reinforcing portion is greater than the maximum diameter of the tool holder taper portion, in this case, the workpiece may be damaged.

[0110] Therefore, when the probing portion of the first tool holder is the tool holder taper portion, the length of the tool holder taper portion of the second tool holder must be greater than the sum H B +M B of the overhang of the tool holder clamping portion and the length of the tool holder taper portion.

[0111] Conversely, if the sum H B +M B of the overhang of the tool holder clamping portion and the length of the tool holder taper portion of the second tool holder is less than or equal to the depth of cut, the second tool holder cannot replace the first tool holder, and the second tool holder fails to match the first tool holder.

[0112] As an example, the depth of cut is 10 cm. The first tool holder A corresponds to H A = 4 cm, D1 A = 1 cm, D2 A = 2 cm, M A = 7 cm, D3 A = 3 cm, L1 A = 3 cm, D4 A = 4 cm, L2 A = 2 cm. The second tool holder B corresponds to H B = 4 cm, D1 B = 1 cm, D2 B = 1.5 cm, M B = 8 cm, D3 B = 3 cm, L1 B = 3 cm, D4 B = 4 cm, L2 B = 2 cm. H A +M A > 10 cm, at this time the probing portion of the first tool holder is the tool holder taper portion. At this time, the probing portion of the second tool holder is the tool holder taper portion. D1 A = D1 B , D2 A > D2B , the length of the second tool holder taper portion is obtained. B = 8 cm, H B + M B = 12 cm, the second tool holder is successfully matched with the first tool holder.

[0113] In some embodiments of the present application, when the first tool holder insertion portion comprises a tool holder taper portion and a tool holder reinforcing portion, the length of the tool holder taper portion of the second tool holder is obtained in the case that the minimum diameter of the taper portion of the second tool holder and the maximum diameter of the taper portion satisfy the condition. If the sum of the length of the tool holder taper portion of the second tool holder and the overhang length of the tool clamping portion is greater than the depth of cut, the second tool holder is successfully matched with the first tool holder. Otherwise, the sum of the length of the tool holder taper portion of the second tool holder and the length of the tool holder reinforcing portion is obtained in the case that the diameter of the tool holder reinforcing portion of the second tool holder satisfies the condition.

[0114] If the sum of the length of the tool holder taper portion of the second tool holder and the length of the tool holder reinforcing portion is greater than the depth of cut, the second tool holder is successfully matched with the first tool holder. Otherwise, the second tool holder is unsuccessfully matched with the first tool holder.

[0115] As an example, the depth of cut is 10 cm. The first tool holder A has H A = 4 cm, D1 A = 1 cm, D2 A = 2 cm, M A = 5 cm, D3 A = 3 cm, L1 A = 3 cm, D4 A = 4 cm, L2 A = 2 cm. The second tool holder B has H B = 4 cm, D1 B = 1 cm, D2 B = 1.5 cm, M B = 4 cm, D3 B = 3 cm, L1 B = 1.8 cm, D4 B = 4 cm, L2 B = 1 cm. H A + M A ≤ depth of cut < H A + M A + L1 A At this time, the insertion portion of the first tool holder is the tool holder taper portion and the tool holder reinforcing portion. At this time, the insertion portion of the second tool holder is the tool holder taper portion or the tool holder taper portion and the tool holder reinforcing portion. D1 A = D1 B , D2 A > D2 B , the length of the tool holder taper portion of the second tool holder is obtained first, HB + M B = 8 <cutting depth. D3 A = D3 B , the length of the shank tapering portion of the second shank and the length of the shank reinforcing portion M B + L1 B , H B + M B + L1 B = 9.8 cm <cutting depth, the second shank fails to match the first shank.

[0116] In some embodiments of the present application, when the probe portion of the first shank comprises a shank tapering portion, a shank reinforcing portion and a shank end portion, the length of the shank tapering portion of the second shank is obtained if the minimum diameter of the tapering portion of the second shank and the maximum diameter of the tapering portion satisfy the condition. If the sum of the length of the shank tapering portion of the second shank and the overhang of the tool clamping portion is greater than the cutting depth, the second shank successfully matches the first shank. Otherwise, the sum of the length of the shank tapering portion of the second shank and the length of the shank reinforcing portion is obtained if the diameter of the shank reinforcing portion of the second shank satisfies the condition.

[0117] If the sum of the length of the shank tapering portion of the second shank and the length of the shank reinforcing portion is greater than the cutting depth, the second shank successfully matches the first shank. Otherwise, the sum of the length of the shank tapering portion of the second shank, the length of the shank reinforcing portion and the length of the shank end portion is obtained if the diameter of the shank end portion of the second shank satisfies the condition.

[0118] If the sum of the length of the shank tapering portion of the second shank, the length of the shank reinforcing portion and the length of the shank end portion is greater than the cutting depth, the second shank successfully matches the first shank. Otherwise, the second shank fails to match the first shank.

[0119] As an example, the cutting depth is 10 cm. The H A = 4 cm, D1 A = 1 cm, D2 A = 2 cm, M A = 5 cm, D3 A = 3 cm, L1 A = 1 cm, D4 A = 4 cm, L2 A = 1 cm. The H B = 4 cm, D1 B = 1 cm, D2 B = 1.5 cm, M B = 4 cm, D3 B = 3 cm, L1 B = 2 cm, D4 B=3.5cm, L2 B =1cm. H A +M A +L1 A ≤ depth of cut <H A +M A +L1 A +L2 A At this point, the protruding part of the first tool holder consists of the tapered portion of the tool holder, the reinforcing portion of the tool holder, and the end portion of the tool holder. At this point, the protruding part of the second tool holder consists of the tapered portion of the tool holder, or the tapered portion of the tool holder and the reinforcing portion of the tool holder, or the tapered portion of the tool holder, the reinforcing portion of the tool holder, and the end portion of the tool holder. D1 A =D1 B D2 A >D2 B First, obtain the length M of the tapered portion of the second tool holder. B H B +M B =8 < depth of cut. D3 A =D3 B Then obtain the sum M of the length of the tapered part of the second tool holder and the length of the reinforcing part of the tool holder. B +L1 B H B +M B +L1 B =10cm=cut depth. D4 A >D4 B Then obtain the sum M of the length of the tapered part of the tool holder, the length of the reinforcing part of the tool holder, and the length of the end of the tool holder. B +L1 B +L2 B H B +M B +L1 B +L2 B =11cm>cut depth, the second tool holder and the first tool holder are successfully matched.

[0120] As another example, the depth of cut is 10cm. The first tool holder A has a H... A =4cm, D1 A =1cm, D2 A =2cm, M A =4cm, D3 A =3cm, L1 A =1cm, D4 A =4cm, L2 A =1cm. H of the second tool holder B B =4cm, D1 B =1cm, D2 B =1.5cm, M B =4cm, D3 B= 3 cm, L1 B = 2 cm, D4 B = 3.5 cm, L2 B = 1 cm. H A + M A + L1 A < H A + M A + L1 A + L2 A At this time, the inserted part of the first holder is the holder taper part, the holder reinforcing part and the holder end part. At this time, the inserted part of the second holder is the holder taper part, or the holder taper part and the holder reinforcing part, or the holder taper part, the holder reinforcing part and the holder end part. D1 A = D1 B , D2 A > D2 B , first obtain the length M of the holder taper part of the second holder B , H B + M B = 8 < H. D3 A = D3 B , then obtain the sum M of the length of the holder taper part and the length of the holder reinforcing part of the second holder B + L1 B , H B + M B + L1 B = 10 cm = H. D4 A > D4 B , then obtain the sum M of the length of the holder taper part, the length of the holder reinforcing part and the length of the holder end part B + L1 B + L2 B , H B + M B + L1 B + L2 B = 11 cm > H, the second holder is successfully matched with the first holder.

[0121] In some embodiments of the present application, the sum of the length of the inserted part of the second holder and the overhang of the tool clamping part is greater than the depth of cut, and the overhang of the tool clamping part of the second holder is also greater than the depth of cut. At this time, the amount of holder insertion does not need to be simulated by the CAM.

[0122] As an example, the CAM program does not output information.

[0123] As another example, if the CAM program has information output, the CAM end will alarm.
