The connecting portion hole is, in particular, a dowel hole for fitting a dowel, particularly a flat dowel or a circular dowel. The connecting portion hole is, for example, an oblong hole.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The problem of the present invention is to provide a connecting portion milling machine that can be used flexibly.

Means for Solving the Problems

[0004] This problem is solved by the connecting portion milling machine according to claim 1.

[0005] The connecting part milling machine includes a contacting device having a contacting structure for statically contacting a connecting part to a workpiece during the formation of a recess, a milling tool, an electric drive device formed to rotate and cut with the milling tool, an electric positioning device formed to move the milling tool relative to the contacting structure along at least two particularly linear degrees of freedom of positioning, and an electronic control unit formed to control the electric positioning device in accordance with movement information, while the electric positioning device brings the milling tool into a movement sequence defined by the movement information along at least two degrees of freedom of positioning, and the milling tool performs a rotary cutting movement to form a recess having a predetermined recess geometry (while the electric positioning device brings the milling tool into a movement sequence defined by the movement information along at least two degrees of freedom of positioning while the milling tool performs a rotary cutting movement to form a recess having a predetermined recess geometry).

[0006] The recess geometry is preferably preset, particularly depending on the movement sequence, and preferably with respect to at least two degrees of freedom of positioning.

[0007] In the above connecting part milling machine, the recess geometry of the recess to be formed is specified by movement information. The recess includes a connecting part hole and may preferably consist only of the connecting part hole. Further, the recess may include, in addition to the connecting part hole, one or more other recesses, for example, access holes to the connecting part hole. The movement information particularly specifies the connecting part hole geometry of the connecting part hole to be formed. The connecting part milling machine is particularly a (handheld) CNC machine and may also be called a (handheld) CNC connecting part milling machine. The recess geometry of the recess to be formed can be easily adapted, particularly using appropriately adapted movement information, such that different recesses, particularly different connecting part holes (for example, for different connecting parts), can be formed by the connecting part milling machine.

[0008] Preferred developments form the subject matter of the dependent claims.

[0009] The present invention also relates to a method for operating a hand-held connecting part milling machine, comprising the following steps: - positioning the connecting part milling machine on the workpiece such that the connecting part milling machine is statically abutted against the workpiece by an abutting structure during the formation of the recess; - controlling (operating) an electrical positioning device according to movement information such that the electrical positioning device brings a milling tool into a movement sequence while the milling tool performs a rotational cutting movement to form a recess including a connecting part hole having a recess geometry preset by the movement sequence (while the milling tool performs a rotational cutting movement to form a recess including a connecting part hole having a recess geometry preset by the movement sequence, the electrical positioning device brings the milling tool into a movement sequence). The present invention relates to the above method.

[0010] The method is advantageously formed corresponding to an embodiment of a hand-held connecting part milling machine.

Modes for Carrying Out the Invention

[0013] In the following description, the x-direction, y-direction, and z-direction, which are spatial directions oriented perpendicular to each other, are referred to. The x-direction is shown as the width direction, the y-direction is shown as the lateral direction, and the z-direction is shown as the depth direction. These directions are for the connecting part milling machine 10 and rotate correspondingly with the milling device when the connecting part milling machine 10 rotates. For the purpose, the depth direction z extends in the direction of the rotation axis (line) of the rotary cutting motion of the milling tool 17 of the connecting part milling machine 10. The width direction x and the lateral direction y extend orthogonally to the rotation axis of the rotary cutting motion, respectively.

[0014] FIG. 1 shows an exemplary configuration of a hand-held connecting part milling machine 10 according to the first embodiment. The connecting part milling machine 10 is used to form a recess 1 in the workpiece 2 (see, for example, FIG. 4). The recess 1 includes a connecting part hole 45 that at least partially accommodates the connecting part 53. The term "hand-held connecting part milling machine" is particularly intended to mean that the entire connecting part milling machine is held by hand by the user during the formation of the recess 1. In particular, the connecting part milling machine 10 is dimensioned and / or configured such that the entire connecting part milling machine 10 can be held by hand by an individual person. For example, the connecting part milling machine 10 has a weight of less than 20 kg or less than 15 kg or less than 10 kg or less than 5 kg.

[0015] The connecting part milling machine 10 includes a housing 3, which is particularly the outer housing of the connecting part milling machine 10. The housing 3 has an exemplary cubic basic shape.

[0016] The connecting part milling machine 10 includes, by way of example, a hand grip 4 disposed on the first side surface 5 of the connecting part milling machine 10. The first side surface 5 can also be referred to as the hand grip side and is, by way of example, oriented perpendicular to the lateral direction y. The first side surface 5 is, by way of example, formed by the wall portion of the housing 3. The hand grip 4 is used to grip the connecting part milling machine 10 and position the connecting part milling machine 10 relative to the workpiece 2. The hand grip 4 is, by way of example, configured in a hump shape (U shape). By way of example, the hand grip 4 is oriented parallel to the width direction x with respect to its longitudinal axis. Alternatively, the hand grip 4 can be oriented parallel to the depth direction z with respect to its longitudinal axis. Also, the hand grip can be configured differently. Preferably, the hand grip 4 is configured to be integrated with the housing 3.

[0017] Preferably, the extension in the width direction x of the housing 3 (not considering the entire hand grip of the connecting part milling machine 10 in particular) is greater than the extension in the depth direction x of the housing 3 (not considering the entire hand grip of the connecting part milling machine in particular). Preferably, the extension in the width direction x of the connecting part milling machine 10 without considering the entire hand grip of the connecting part milling machine 10 is greater than the depth direction z.

[0018] The connecting part milling machine 10 includes, by way of example, a contact device 6 arranged on the second side 7 of the connecting part milling machine 10. The second side 7 can also be referred to as the contact side and is, by way of example, oriented perpendicular to the depth direction z. The contact device 6 has a contact structure 8 for statically contacting the connecting part milling machine 10 against the workpiece 2 during the formation of the recess 1. By way of example, the contact structure includes a first structural part 9 and a second structural part 11. The second structural part 11 is, by way of example, connected to the first structural part 9 in the lateral direction y. The first structural part 9 and the second structural part 11 are used to simultaneously and statically contact the workpiece 2 during the formation of the recess 1. The first structural part 9 defines a first contact plane, and the second structural part 11 defines a second contact plane. For example, the first structural part 9 has a first contact surface that defines the first contact plane, and / or the second structural part 11 has a second contact surface that defines the second contact plane. For the sake of expediency, the connecting part milling machine 10 contacts the workpiece 2 by means of the contact structure 8, in particular by means of the first contact plane and the second contact plane simultaneously, during the formation of the recess 1, especially during the overall formation of the recess. The first contact plane is, by way of example, oriented perpendicular to the depth direction z and is preferably continuously fixed in such a way that, in this orientation, in particular the orientation of the first contact plane does not change.

[0019] The second structural part 11 is, in particular, preferably pivotably supported relative to the first structural part 9 about a (virtual) pivot axis 15 oriented parallel to the x-axis. Preferably, the second structural part 11 is pivotable about a pivot axis 15 that is oriented perpendicular to the axis of rotation of the cutting movement of the milling tool 17 of the connecting part milling machine 10. The pivot axis 15 is, by way of example, arranged in the lateral direction y between the first structural part 9 and the second structural part 11. By way of example, the contact device 6 has a pivot bearing that defines the pivot axis 15.

[0020] In order to set (adjust) a fixed angle 12 (see, for example, FIG. 5), which is particularly adapted to the workpiece 2, between the first abutment plane and the second abutment plane, the second structural part 11 can be fixed at a plurality of different swivel positions relative to the first structural part 9. The angle 12 is particularly in the z-y plane. By swiveling the second structural part 11 relative to the first structural part 9 (about the swivel axis 15), the second abutment plane can be swiveled relative to the first abutment plane (and particularly relative to the depth direction z). Preferably, the connecting part milling machine 10 is provided with a fixing device, and the second structural part 11 can be fixed at a plurality of different swivel positions relative to the first structural part 9 using the fixing device, for example, in a fitting manner and / or in an engaging manner. Exemplarily, the fixing device preferably comprises at least one structural part guide element 41 formed as a guide slot. Exemplarily, at least one structural part guide element 41 is fixed to the second structural part 11 and swivels with the second structural part about the swivel axis 15. Preferably, at least one structural part guide element 41 defines the swivel axis 15 or contributes to the definition of the swivel axis 15. At least one structural part guide element 41 can particularly be regarded as part of the swivel axis. The fixing device preferably comprises an operating element 42, which is exemplarily configured as a lever, and through whose operation, the second structural part 11 can be fixed at its current swivel position relative to the first structural part 9, for example, in a fitting manner and / or in an engaging manner. In particular, it is possible to fix the second structural part 11 at its current swivel position relative to the first structural part 9, for example, in a fitting manner and / or in an engaging manner, by fixing at least one structural part guide element 41 relative to the first structural part 9 at its current swivel position using the operating element 42.

[0021] The second structural part 11 is, in particular, expediently pivotable to a first pivot position in which the second abutment plane lies in the same plane as the first abutment plane. In the first pivot position, the angle 12 is in particular 180°. In the first pivot position, the second structural part 11 is oriented perpendicular to the depth direction z (see, for example, FIG. 1). Preferably, the first pivot position is one end position of the second structural part 11. The second structural part 11 is pivotable about the pivot axis 15, in particular to an angle 12 of at least 90° or less, in order to reduce the angle 12 from the first pivot position. The second structural part 11 is displaceable to a second pivot position in which the angle 12 is less than 180°, for example 90° or less.

[0022] Exemplarily, the first structural part 9 and / or the second structural part 11 are configured in the form of a plate. The abutment device 6 can also be referred to as an abutment table. The first structural part 9 exemplarily includes a first abutment part 13 and a second abutment part 14, and these first and second abutment parts are, in particular, configured in the form of a plate and / or are arranged spaced apart from each other. The first abutment part 13 and the second abutment part 14 together define a first abutment plane and, expediently, both abut the workpiece 2 simultaneously during the formation of the recess.

[0023] Exemplarily, the abutment device 6 comprises a first abutment projection 19 and / or a second abutment projection 21, and these first and second abutment projections are arranged on the first structural part 11, in particular on the first abutment part 13 and the second abutment part 14, and preferably extend in the depth direction z from the first structural part 1. Expediently, the connecting part milling machine 10 can be abutted in a direction perpendicular to the depth direction z by at least one of the abutment projections 19, 21 during the formation of the recess 1. Expediently, the abutment projections 19, 21 are supported movably relative to the first abutment plane and, in particular, the abutment projections 19, 21 are displaceable to a retracted state in which they do not project from the first abutment plane, expediently, and / or the abutment projections 19, 21 are displaceable to a protruding state in which they project from the first protruding plane, expediently.

[0024] Preferably, the abutment structure 8 has an opening 16. Exemplarily, the opening 16 is arranged between the two abutment parts 13, 14 in the width direction x. Exemplarily, the milling tool 17 extends from the internal space 18 (especially surrounded by the housing 3) through the opening 16 to the connecting part milling disk 10, especially to the outside of the housing 3. The milling tool 17 can be positioned, especially along at least two positioning degrees of freedom 31, 32, 33, using the electrical positioning device 18 of the connecting part milling disk 10 within the opening 16. The opening 16 has, exemplarily, an elongated cross-section and / or a rectangular cross-section. The opening 16 is oriented perpendicular to the depth direction z with its opening plane.

[0025] Preferably, the opening 16 extends across the first structural part 9 and the second structural part 11. Advantageously, the opening 16 is present in the first structural part 9 (exemplarily between the first abutment part 13 and the second abutment part 14) and extends therefrom (exemplarily in the lateral direction y) into the second structural part 12. Exemplarily, the opening 16 is cut by an (imaginary) axis of rotation 15. Exemplarily, the axis of rotation 15 cuts the movement range of the milling tool 17, especially the x-y movement range or the x-y-z movement range. The movement range is formed by at least two or three positioning degrees of freedom 31, 32, 33 provided by the positioning device 18. For example, the movement range is a plane, especially the x-y plane, or a volume (space), especially the x-y-z volume (space), within which the milling tool 17 can be positioned using the positioning device 18.

[0026] Exemplarily, the opening 16 extends to the first structural part edge 23 of the first structural part 9 on the side opposite to the second structural part 11 (especially in the negative lateral direction y) and, advantageously, opens at the edge 23 in the negative lateral direction y. According to an alternative configuration, the opening 16 does not extend to the first structural part edge 23, so that, as a result, a web-like part extends from the first abutment part 13 to the second abutment part 14 especially below the opening 16 in the negative lateral direction y.

[0027] Exemplarily, the connecting part milling disk 10 includes a contact structure handgrip 22 arranged in the second structural part 11. For the purpose, the second structural part 11 is rotatable relative to the first structural part 9 via the contact structure handgrip. Exemplarily, the contact structure handgrip 22 is configured in a handle shape. Also, the contact structure handgrip 22 can be configured in a U-shaped (grooved) form. For example, the user can hold the connecting part milling disk 10 with one hand at the handgrip 4, and at the same time, hold it with the other hand at the contact structure handgrip 22. Preferably, the contact structure handgrip 22 is oriented parallel to the width direction x with its handgrip axis. The (virtual) axis of the contact structure handgrip 22 that the user grasps when gripping the contact structure handgrip 22 (in particular according to the regulations) is called the handgrip axis.

[0028] The connecting part milling disk 10 includes a milling tool 17 configured as a groove milling disk, preferably as a T-groove milling disk. The milling tool 17 is configured as an undercut milling disk in particular. An undercut milling disk is a milling disk that can form a recess 1, in particular a connecting part hole 45, having an undercut, particularly an undercut acting along a direction parallel to the axis (line) of the cutting movement. The milling tool 17 can be configured as a groove milling disk, for example. Also, the milling tool 17 can be configured as a drilling machine or a drill milling disk particularly when the recess 1 to be formed, in particular the connecting part hole 45, does not have an undercut. The milling tool 17 includes a shaft part 24 and a milling head 25 arranged at one end of the shaft part 24, exemplarily. Exemplarily, the shaft part 24 is oriented in the depth direction z with its longitudinal axis.

[0029] The connecting part milling machine 10 is provided with an electric drive device 27 which is formed such that the milling tool 17 is brought into (is subjected to) a rotary cutting motion. The axis (line) of the rotary cutting motion is expediently oriented in the depth direction z. The electric drive device 27 includes, for example, an electric motor 28 in order to bring the milling tool 17 into a rotary cutting motion. Expediently, the drive device 27 is provided with a tool connection point 29 to which the milling tool 17 is attached. For example, the tool connection point 29 has a male thread, and the milling tool 17 has a female thread for screwing the milling tool 17 onto the male thread. The male thread is preferably arranged on the spindle 49 of the drive device 27.

[0030] The connecting part milling machine 10 is provided with an electric positioning device 26 which is formed to move the milling tool along at least two particularly linear positioning degrees of freedom 31, 32, 33 relative to the abutment structure 8. In the case of a positioning degree of freedom, it is hereby always intended that the degree of freedom of the electric positioning device 26 is meant. In particular, the positioning degrees of freedom 31, 32, 33 are degrees of freedom along which the electric positioning device 26 can be approached to a position indicated by the electronic control unit 37 of the connecting part milling machine 10. In particular, positioning according to a (particularly arbitrary) target position set by the control unit 37 is possible using the positioning device 26 along the positioning degrees of freedom 31, 32, 33. Expediently, the target position defines a target value for each positioning degree of freedom 31, 32, 33.

[0031] Preferably, the positioning device 26 is formed to move the milling tool relative to the abutment structure 8 along three particularly linear positioning degrees of freedom 31, 32, 33, and the three positioning degrees of freedom 31, 32, 33 are preferably oriented perpendicular to each other. Preferably, one of the positioning degrees of freedom, particularly the first positioning degree of freedom 31, extends perpendicular to the axis of rotation of the cutting movement and / or parallel to the abutment plane defined by the abutment structure 8, particularly the first abutment plane. In particular, the first positioning degree of freedom 31 extends in the width direction x. Preferably, one of the positioning degrees of freedom, particularly the second positioning degree of freedom 32, extends in the transverse direction y, i.e., particularly perpendicular to the first positioning degree of freedom 31 and / or perpendicular to the axis of rotation of the cutting movement. Preferably, one of the positioning degrees of freedom, particularly the third positioning degree of freedom 33, extends in the axial direction of the axis of rotation of the cutting movement and / or perpendicular to the abutment surface defined by the abutment structure, particularly the first abutment plane. In particular, the third positioning degree of freedom 33 extends in the depth direction z.

[0032] Exemplarily, the positioning device 26 providing the positioning degrees of freedom 31, 32, 33 has three linear axes oriented perpendicular to each other. Preferably, the positioning device 26 comprises three linear drives 34A, 34B, 34C used particularly to provide the three linear axes. Advantageously, each linear drive 34A, 34B, 34C comprises an electric motor. The three linear drives 34A, 34B, 34C include a first linear drive 34A, a second linear drive 34B, and a third linear drive 34C.

[0033] The first linear drive unit 34A includes a first guide element 35A, particularly a first guide rail, which is exemplarily oriented in the width direction x with respect to the longitudinal axis. The first linear drive unit 34A includes a first drive element 36A, particularly a first carriage, supported by the first guide element 35A, and the first drive element can be electrically driven by the first linear drive unit 34A along the first positioning degree of freedom 31 relative to the first guide element 35A. Preferably, the first carriage engages with the first guide rail and is particularly held in an engaging manner in the first guide rail, so that the first carriage can move only in the direction of the first positioning degree of freedom 31 for the intended purpose. For example, the first guide rail has an X-shaped profile (cross section), and the profile is engaged by the first carriage on three sides.

[0034] The second linear drive unit 34B includes a second guide element 35B, particularly a second guide rail, which is exemplarily oriented in the lateral direction y with respect to the longitudinal axis. The second linear drive unit 34B includes a second drive element 36B, particularly a second carriage, supported by the second guide element 35B, and the second drive element can be electrically driven by the second linear drive unit 34B along the second positioning degree of freedom 32 relative to the second guide element 35B. Preferably, the second carriage engages with the second guide rail and is particularly held in an engaging manner in the second guide rail, so that the second carriage can move only in the direction of the second positioning degree of freedom 32 for the intended purpose. For example, the second guide rail has an X-shaped profile (cross section), and the profile is engaged by the second carriage on three sides.

[0035] The third linear drive unit 34C includes a third guide element 35C, particularly a third guide rail, which is exemplarily oriented in the depth direction z with respect to the longitudinal axis. The third linear drive unit 34C includes a third drive element 36C, particularly a third carriage, which is supported by the third guide element 35C, and the third drive element can be electrically driven by the third linear drive unit 34C along the third degree of positioning freedom 33 relative to the third guide element 35C. Preferably, the third carriage engages with the third guide rail and is particularly held in an engaging manner in the third guide rail, so that the third carriage can move only in the direction of the third degree of positioning freedom 33 for the intended purpose. For example, the third guide rail has an X-shaped profile (cross section), and the profile is engaged by the third carriage on three sides.

[0036] Exemplarily, since the drive device 27 is fixed to the third linear drive unit 34C, particularly the third drive element 36C, the drive device 27 (and thus the milling tool 17) can be positioned by the third linear drive unit 34C along the third degree of positioning freedom 33. Exemplarily, since the third linear drive unit 34C is fixed to the second linear drive unit 34B, particularly the second drive element 36B (particularly by the third guide element 35C), the third linear drive unit (and thus the drive device 27 having the milling tool 17) can be positioned by the second linear drive unit 34B along the second degree of positioning freedom 33. Exemplarily, since the second linear drive unit 34B is fixed to the first linear drive unit 34A, particularly the first drive element 36A (particularly by the first guide element 35A), the second linear drive unit 34B (and thus the third linear drive unit 34C and the drive device 27 having the milling tool 17) can be positioned by the first linear drive unit 34A along the first degree of positioning freedom 31.

[0037] Exemplarily, the first linear drive unit 34A, in particular the second guide element 35A, is arranged inside against the contact side 7, in particular on the wall portion 51 facing the contact side 7 of the connecting portion milling disk 10. Exemplarily, the first linear drive unit 34A, in particular the first guide element 35A, is arranged in the (positive) lateral direction y further than the opening 16. In other words, the first linear drive unit 34A, in particular the first guide element 35A, is arranged between the opening 16 and the first side 5 in the y direction, exemplarily. In the orientation of the connecting portion milling disk 10 where the lateral direction y is vertically oriented and shown upward, the first linear drive unit 34A, in particular the first guide element 35A, is arranged above the opening 16. The connecting portion milling disk 10, in particular the housing 3, includes a wall portion 51 facing the contact side 7 that is oriented perpendicularly to the depth direction z, exemplarily. The contact device 6 is arranged on the outer side of the wall portion 51 (i.e., the side facing the positive depth direction z exemplarily), and the first linear drive unit 34A is arranged on the inner side of the wall portion 51 (the side facing the negative depth direction z exemplarily).

[0038] Preferably, the maximum displacement distance for positioning the milling tool 17 along the positioning degree of freedom 31 extending in the width direction x is at least 1.3 cm, and / or the maximum displacement distance for positioning the milling tool along the positioning degree of freedom 32 extending in the lateral direction y is at least 0.4 cm, and / or the maximum displacement distance for positioning the milling tool along the positioning degree of freedom 33 extending in the depth direction z is at least 1.1 cm.

[0039] Preferably, the maximum displacement distance of the milling tool 17 along the second positioning degree of freedom 32 is at least 20%, at least 50% or at least 70% of the maximum displacement distance of the milling tool 17 along the first positioning degree of freedom 31.

[0040] According to one possible configuration, the maximum displacement distance of the milling tool 17 along the first positioning degree of freedom 31 is at least 6 cm, and / or the maximum displacement distance of the milling tool 17 along the second positioning degree of freedom 32 is at least 5 cm, and / or the maximum displacement distance of the milling tool 17 along the third positioning degree of freedom 32 is at least 4 cm.

[0041] According to another possible configuration, the maximum displacement distance of the milling tool 17 along the first positioning degree of freedom 31 is 7.6 cm, and / or the maximum displacement distance of the milling tool 17 along the second positioning degree of freedom 32 is 2.9 cm, and / or the maximum displacement distance of the milling tool 17 along the third positioning degree of freedom 32 is 4.5 cm.

[0042] The connecting part milling machine 10 includes an electronic control unit 37, which includes, for example, a microprocessor, particularly a microcontroller, and is preferably formed as a microcontroller. Since the control unit 37 is formed to control (operate) the electric positioning device 26 according to the motion information, the electric positioning device 26 is displaced along at least two positioning degrees of freedom 31, 32, 33 in the motion sequence defined by the motion information, while the milling tool 17 performs a rotary cutting motion to form a recess 1 with a connecting part hole 45 having a preset recess geometry. The term "recess geometry" intends the geometry of the recess to be formed, and thus, in particular, the dimensions and / or shape of the recess 1 to be formed, particularly the connecting part hole 45, at each positioning degree of freedom 31, 32, 33 are intended. Preferably, the milling tool 17 performs a rotary cutting motion during at least part of the motion sequence, optionally during the entire motion sequence. In particular, the milling tool 17 performs a rotary cutting motion during movement along at least the first positioning degree of freedom 31, and / or during movement along the second positioning degree of freedom 32, and / or during movement along the third 33 (in the motion sequence).

[0043] (While performing a rotary cutting motion), the execution of the motion sequence defined by the motion information can also be referred to as a forming (manufacturing) act. The motion information is, for example, stored as data in an electronic control unit 37, and / or received by the electronic control unit 37, and / or generated by the electronic control unit 37. For example, the motion information defines a plurality of successive target positions of the milling tool 17, particularly for at least two positioning degrees of freedom 31, 32, 33 each. Preferably, the motion information defines the feed rate, feed direction and / or milling machine rotational speed for the milling tool, particularly for each motion of the milling tool between two successive targets.

[0044] Preferably, the motion information defines a motion sequence along three positioning degrees of freedom 31, 32, 33, and the motion sequence sets the recess geometry for the three positioning degrees of freedom. For example, the motion information defines a plurality of successive target positions of the milling tool 17, particularly for three positioning degrees of freedom 31, 32, 33 each.

[0045] Preferably, the electronic control unit 37 has a plurality of different motion information. Each motion information is assigned to each recess geometry. Preferably, the recess geometries are different from each other. The control unit 37 is formed to control (operate) the positioning device 26 in accordance with one of the motion information in order to form recess 1 with the recess geometry assigned to the motion information. The expression that the recess geometry is assigned to the motion information is intended to mean that by executing the forming act with the said motion information, it is possible to form recess 1 having the assigned recess geometry.

[0046] Optionally, the control unit 37 is formed to select, for example in accordance with a user input, the motion information to be used for forming recess 1 from the existing motion information, and to control (operate) the positioning device 26 in accordance with the selected motion information in order to form recess 1 with the recess geometry assigned to the motion information.

[0047] Preferably, the connecting part milling machine 10 exemplarily includes an operating device 52 arranged outside in the housing 3. The operating device 52 includes at least one operating element 53 for operating the connecting part milling machine 10, for example, a button. For example, the operating element 53 is used to start the forming action for forming the recess 1.

[0048] Optionally, via the operating device 52, a user input can be executed to select the motion information to be used.

[0049] Optionally, the connecting part milling machine 10 includes a suction passage capable of sucking particles generated during the formation of the recess 1, particularly cutting chips.

[0050] Hereinafter, with reference to FIG. 5, the state in which the connecting part milling machine 10 abuts against the workpiece 2 and the recess in the workpiece 2 is formed by the milling tool 17 will be described in detail.

[0051] The connecting part milling machine 10 abuts particularly flatly against the first workpiece surface 43 by the first structural part 9, particularly the first abutting plane. The first workpiece surface is exemplarily oriented perpendicular to the depth direction z. Exemplarily, the first workpiece surface 43 is a flat surface and particularly forms the flat first side of the workpiece 2. The first workpiece surface 43, particularly the first side of the workpiece 2, is exemplarily shorter than the connecting part milling machine 10 in the lateral direction y.

[0052] The connecting part milling machine 10 abuts particularly flatly against the second workpiece surface 44 by the second structural part 11, particularly the second abutting plane. Exemplarily, the second workpiece surface 44 is a flat surface and particularly forms the flat second side of the workpiece 2. The second workpiece surface 44 is bent (angled) with respect to the first workpiece surface 43 and is particularly not oriented perpendicular to the depth direction z. The second workpiece surface 44 is not oriented parallel to the first workpiece surface 43.

[0053] The second structural part 11 is fixed at a swivel position where the first abutment plane on the first workpiece surface 43 and the second abutment plane on the second workpiece surface 44 (in particular flat) abut simultaneously. Between the abutment planes 11, 12, an angle 12, preferably smaller than 180° and / or 90° or more, is set (adjusted) by the swivel position of the second structural part 11.

[0054] The recess 1 to be formed opens, by way of example, in the first workpiece surface 43. Preferably, the recess 1 to be formed opens in the first workpiece surface 43 and in the second workpiece surface 44. When forming the recess, the positioning device 26 positions the milling tool 17 in the lateral direction y until the milling tool 17, in particular the milling head 25, is arranged within or at a part of the opening 16 present in the second structural part 11, in particular while the milling tool 17 performs a cutting movement. In this way, it is possible to form a recess 1 that opens in the second workpiece surface 44 (in particular without repositioning the connecting part milling machine 10).

[0055] Optionally, the milling tool 17 can be pushed in from above through the second workpiece surface 44 to form the recess 1. For this particular purpose, the connecting milling table 10 first uses the positioning device 26 to move the milling tool 17 in the lateral direction y while performing a positioning movement until the milling tool 17, in particular the milling head 25, is located within or disposed in part within the opening 16 of the second structural part 11, preferably further (in the positive) lateral direction y than the second workpiece surface 44 (or the lower part of the second workpiece surface 44). Advantageously, the milling tool 17 does not perform a cutting movement during this positioning movement and thus, advantageously, does not rotate. The milling tool 17, in particular the milling head 25, is advantageously disposed outside the first workpiece surface 43, in particular in front of the first workpiece surface 43, during this positioning movement. Preferably, after the positioning movement (and / or another positioning movement of the milling tool 17 in the positive depth direction z), the connecting milling table 10 causes the milling tool 17 to perform a cutting movement and, while the milling tool 17 performs the cutting movement, the milling tool 17 is formed to move into the second workpiece surface 44 to form the recess 1 by movement of the milling tool 17 using the positioning device 26 in the (negative) lateral direction y and / or in the (positive) depth direction z.

[0056] The recess 1 to be formed includes a connecting portion hole 45. The hole for at least partial insertion of the connecting portion shall be called the connecting portion hole 45. The connecting portion is an element that joins two workpieces. An example of a connecting portion is a dowel, in particular a wooden dowel. The connecting portion hole 45 is in particular a connecting groove.

[0057] The connection part hole 45 preferably has an undercut 46 acting along the depth direction z. The depth direction z is oriented parallel to the rotation axis (line) of the cutting motion. The depth direction z is particularly the groove depth direction. The expression that the undercut 46 acts along the depth direction z is intended to mean that the undercut 46 is used to prevent the connection part fitted into the connection part hole and engaged with the undercut 46 from being pulled out along the depth direction z (particularly the negative depth direction z). The undercut 46 is particularly used to accommodate the engaging protrusion 57 of the connection part to be fitted into the connection part hole. For the purpose, the undercut 46 is a recessed part, particularly an elongated recessed part, such as a groove, and the longitudinal axis of the elongated recessed part is preferably oriented parallel to the width direction x. The undercut 46 is preferably arranged within the range of the bottom 47 of the connection part hole of the connection part hole. The bottom 47 of the connection part hole is, for example, the groove bottom. The bottom 47 of the connection part hole is, for example, oriented perpendicular to the depth direction y and / or parallel to the lateral direction y. The connection part hole 45 opens preferably at the first workpiece surface 43, particularly only at the first workpiece surface 43.

[0058] Preferably, the plurality of motion information includes first motion information assigned to the first recess geometry in which the connection part hole 45 has an undercut 46 and second motion information assigned to the second recess geometry in which the connection part hole 45 has no undercut. An example of the connection part hole 45 having no undercut is the dowel recess described later.

[0059] Preferably, the movement sequence defined by the movement information sets the connection part hole 48 and the access hole 48 to the connection part hole 45. The electronic control unit 37 causes the electric positioning device 26 to bring the milling tool 17 into the movement sequence, while, particularly during one continuous operating process and, in particular, without changing (modifying) the connection part milling machine 10, the milling tool performs a rotary cutting movement to form the connection part hole 45 and the access hole 48 (particularly during one continuous operating process and, in particular, without changing (modifying) the connection part milling machine 10, while the milling tool performs a rotary cutting movement to form the connection part hole 45 and the access hole 48, the electric positioning device 26 causes the milling tool 17 to enter the movement sequence), and is formed to control (operate) the electric positioning device 26 according to the movement information.

[0060] Exemplarily, the recess 1 to be formed includes the access hole 48 to the connection part hole 45. The access hole 48 extends, for example, laterally in the y direction from the connection part hole 45 to the second workpiece surface 44 at which the access hole 48 opens. Exemplarily, the access hole 48 opens at the first workpiece surface 43 and the second workpiece surface 44. In particular, since the access hole 48 is used to provide an access part for the tool 56 to the connection part that is fitted into the connection part hole 45 (particularly via the second workpiece surface 44), for example, while the operating part 55 of the connection part can be operated by the tool 56, the connection part is fitted into the connection part hole 45.

[0061] Preferably, the geometry of the connection part hole 45 and / or the access hole 48 is set particularly with respect to three positioning degrees of freedom 31, 32, 33 by the movement sequence defined using the movement information. The movement information particularly sets the extension of the connection part hole 45 and / or the access hole 48 in the width direction x, the lateral direction y, and / or the depth direction z.

[0062] For the purpose, the recess geometry assigned to the motion information includes the connection hole geometry and / or the access hole geometry. Therefore, for the purpose, the connection hole geometry of the connection hole 45 and / or the access hole geometry of the access hole 48 are assigned to the motion information. The expression that the connection hole geometry or the access hole geometry is assigned to the motion information is intended to mean that the assigned connection hole geometry or the assigned access hole geometry can be formed by executing the forming act in the motion information.

[0063] Preferably, using the connection part milling machine 10, selectively, a recess having no undercut (for example, the dowel recess described later) and / or a recess having an undercut (the rotary connection part recesses 1A, 1C and / or the motion mechanism connection part recesses 1E, 1F described later) and / or a recess having an access hole (for example, the rotary connection part recess 1A and / or the motion mechanism connection part recess 1E described later) and / or a recess having no access hole (for example, the rotary connection part recess 1C and / or the motion mechanism connection part recess 1F described later) and / or a disk-shaped main part and a recess having an undercut (for example, the rotary connection part recesses 1A, 1C described later) can be formed.

[0064] Hereinafter, with reference to FIGS. 10 to 16, various recesses 1 that can preferably be formed by the connecting portion milling machine 10 (particularly as described later) will be described. FIGS. 10 to 16 show two workpieces 2A, 2B each having at least one recess 1. In FIGS. 10 to 16, each coordinate system is entered for each workpiece 2A, 2B, and the coordinate system corresponds to the possible (or necessary) orientation of the connecting portion milling machine 10 when forming one or more recesses 1 of the assigned workpiece 2. For the purpose, the connecting portion milling machine 10 is statically in contact with each of the workpieces 2A, 2B in which the recess 1 is formed while forming each (particularly the whole) of the recesses 1 described later, particularly simultaneously by the contact structures 8, particularly both structural parts 9, 11, particularly by the first structural part 9 on the first workpiece surface 43A and by the second structural part 11 on the second workpiece 44A simultaneously (or by the first structural part 9 on the first workpiece surface 43B and by the second structural part 11 on the second workpiece surface 44B simultaneously).

[0065] FIG. 10 shows a workpiece arrangement structure 30 including a first workpiece 2A and a second workpiece 2B, and a connecting portion 53 configured as an exemplary rotary connecting portion 53A. Optionally, the workpiece arrangement structure 30 further includes two other connecting portions 53 configured as dowels, exemplarily as flat dowels 53B. Alternatively, another connecting portion 53 can also be configured as a circular dowel 53C as shown in FIG. 11.

[0066] The rotary connection part 53A illustratively has a disc portion and preferably includes a connection part main body 54 having two main sides in the shape of two circular parts. The main sides are arranged parallel to each other. The outer contour of each main side includes an arc portion 58 and a chord portion 59 connecting both ends of the arc portion 58. The connection part main body 54 is illustratively configured as a hexagonal recessed portion, and for the purpose, it includes an operation portion 55 present on at least one of the main sides concentric with the arc portion 58. A tool 56 illustratively configured as a hexagonal socket can be fitted into the operation portion 55. The rotary connection part 53A includes an engagement protrusion 57, and the engagement protrusion protrudes vertically from each main side of the connection part main body 54 and is illustratively arranged only at the end portions, particularly the end portions of each arc portion 58. Illustratively, four engagement protrusions 57 are provided, and each engagement protrusion 57 is arranged at each end portion of the arc portion 58.

[0067] The dowel illustratively configured as a flat dowel 53B has a cylindrical shape each having a base surface, and the outer contour of the base surface includes two straight portions extending in parallel and two rounded, particularly arc-shaped end portions connecting the straight portions. The circular dowel 53C each has a cylindrical shape.

[0068] The first workpiece 2A illustratively has three recesses 1, and includes a connection part recess, particularly a rotary connection part recess 1A that partially accommodates the connection part, particularly the rotary connection part 53A, and optionally, a first workpiece surface 43A provided with two dowel recesses, particularly flat dowel recesses 1B that partially accommodate each dowel, particularly the flat dowel 53B. Alternatively, the dowel recess can be formed as a circular dowel recess 1D (see FIG. 11). Each dowel recess is a recess having a connection part hole. In particular, each dowel recess is a connection part hole. The connection part recess illustratively includes a connection part hole 45 and an access hole 48. The first workpiece 2A further includes a second workpiece surface 44A, and the second workpiece surface is illustratively oriented perpendicular to the first workpiece surface 43A and is particularly connected to the first workpiece surface 43A via a common edge 61.

[0069] The second workpiece 2B is provided, by way of example, with three recesses 1, with a connection recess, in particular a rotary connection recess 1C, which partially accommodates the connection part, in particular the rotary connection part 53A, and optionally with two dowel recesses, in particular flat dowel recesses 1B or circular dowel recesses 1D, which partially accommodate each dowel, in particular the flat dowel 53B, on a first workpiece surface 43B. Alternatively, the dowel recesses can be formed as circular dowel recesses 1D (see FIG. 11). The connection recess is provided, by way of example, with a connection hole 45 and in particular without an access hole 48. The connection recess is a recess having a connection hole. In particular, a connection recess without an access hole is a connection hole. The second workpiece 2B has a second workpiece surface 44B, which is, by way of example, oriented perpendicular to the first workpiece surface 43B and is in particular connected to the first workpiece surface 43B via a common edge 61.

[0070] The workpiece placement structure 30 can be brought into an assembled state, in which the first workpiece 2A is connected to the second workpiece 2B via the connecting portion 53, particularly the rotary connecting portion 53A and / or one or more flat dowels 53B (or circular dowels 53C), such that the second workpiece 2B is fixed to the first workpiece 2A in all spatial directions in particular, and / or the second workpiece 2B abuts particularly flatly against the first workpiece surface 43A of the first workpiece 2A at its first workpiece surface 43B. In the assembled state, the connecting portion 53, particularly the rotary connecting portion 53A, is fitted into the recess 1 of the first workpiece 2A, illustratively the rotary connecting portion recess 1A, and the recess 1 of the second workpiece 2B, illustratively the rotary connecting portion recess 1C. Further, another connecting portion 53, illustratively the flat dowel 53B (or circular dowel 53C), is fitted into the flat dowel recesses 1B (or flat dowel recesses 1D) of both workpieces 2A, 2B. Illustratively, to fix the second workpiece 2B to the first workpiece 1A, the entire rotary connecting portion 53A is rotated using the tool 56 while being fitted into at least the rotary connecting portion recess 1A of the first workpiece 2A by engaging the tool 56 with the operating portion 55 through the access hole 48 such that the tool 56 (and thus the entire rotary connecting portion 53A) rotates about a rotation axis extending parallel to the y - direction. Thus, at least one engaging projection 57, illustratively two engaging projections 57, engages with the rotary connecting portion recess 1C of the second workpiece 2B (particularly having the undercut 46), and at least one engaging projection 57, illustratively two engaging projections 57, engages with the rotary connecting portion recess 1A of the first workpiece 2A (particularly having the undercut 46).

[0071] The following describes the geometric shapes of various recesses that can be formed by the connecting - portion milling machine 10.

[0072] First, regarding the dowel recesses: Each dowel recess has, by way of example, a cylindrical shape. In particular, the cross-section of each dowel recess is constant along each cylindrical axis (which is, by way of example, oriented parallel to the depth direction z). Each dowel recess opens in each of the first workpiece surfaces 43A, 43B (in particular, only in said first workpiece surfaces 43A, 43B).

[0073] Each flat dowel recess 1B has a base surface, and its outer contour comprises two straight portions 62 extending in parallel and two rounded, in particular arcuate, end portions 63 connecting said straight portions. Each circular dowel recess 1D has, by way of example, a cylindrical shape. For the purpose, the dowel recesses, in particular the flat dowel recesses and / or the circular dowel recesses, do not have an undercut.

[0074] The connecting part milling machine 10 is formed so as to form dowel recesses, in particular flat dowel recesses 1B and / or circular dowel recesses 1D, as recesses 1. In particular, the connecting part milling machine 10 has movement information assigned to the dowel recesses for forming the dowel recesses, movement information assigned to the flat dowel recesses 1B in particular for forming the flat dowel recesses 1B and / or movement information assigned to the circular dowel recesses 1D for forming the circular dowel recesses 1D.

[0075] During the formation of the dowel recesses, in particular the flat dowel recesses 1B and / or the circular dowel recesses 1D, the connecting part milling machine 10 performs the forming act according to the movement information assigned to the dowel recesses to be formed, and at this time, in accordance with the movement information of the milling tool 17 (which performs a cutting movement), it moves in the width direction x and the transverse direction y defining the cross-section of the dowel recess and in the z direction defining the extension of the dowel recess along the cylindrical axis.

[0076] Next, the rotary connecting part recess 1A will be described. The rotary connecting part recess 1A may also be called a first type of rotary connecting part recess.

[0077] The rotation connection part recess 1A preferably includes a connection part hole 45 having at least one undercut 46. Exemplarily, the connection part hole 45 is provided with two undercuts 46. Preferably, the connection part hole 45 includes a main part 64 which, for the purpose, has the shape of a disc part and is used to at least partially accommodate the connection part body 54. The main part 64 is oriented perpendicular to the first workpiece 43A in its disc plane and / or perpendicular to the lateral direction y. The main part 64 opens only at the first workpiece surface 43A of the first workpiece 2A, in particular only at the first workpiece surface 43A of the first workpiece 2A. Each undercut 46 has, exemplarily, an arcuate, in particular circular-arc-shaped extension. For the purpose, each undercut 46 is configured in a ring part shape. Each undercut 46 is provided, exemplarily, around an axis oriented parallel to the lateral direction y, in particular around a ring axis, and / or is oriented concentrically with respect to the main part 64. Exemplarily, one undercut 46 follows the main part 45 in the positive lateral direction y, and another undercut 46 follows the main part 45 in the negative lateral direction y. Each undercut 46 opens only at the first workpiece surface 43A, in particular only at the first workpiece surface 43A based on the first workpiece 2A.

[0078] The rotation connection part recess 1A includes an access hole 48 which, exemplarily, is configured in a cylindrical shape and, for the purpose, extends from the main part 45 along the lateral direction y to the second workpiece surface 44A and opens at the second workpiece surface. The cylindrical axis of the access hole 48 is, exemplarily, oriented parallel to the y direction. For the purpose, the access hole 48 opens at the first workpiece surface 43A of the first workpiece 2A and, exemplarily, penetrates the common edge 61 of the first workpiece 2A.

[0079] The connecting part milling machine 10 is formed so as to form a rotary connection part recess 1A as the recess 1. In particular, the connecting part milling machine 10 has motion information for forming the rotary connection part recess, which is assigned to the rotary connection part recess 1A.

[0080] During the formation of the rotary connection part recess 1A, the connecting part milling machine 10 performs the forming act according to the motion information assigned to the rotary connection part recess 1A to be formed. At this time, according to the motion information, the milling tool 17 (which performs a cutting motion) is moved in the width direction x, the lateral direction y, and the depth direction z that define the recess geometry of the rotary connection part recess 1A.

[0081] Next, the rotary connection part recess 1C, which can also be called the second type of rotary connection part recess, will be described.

[0082] For the purpose, the rotary connection part recess 1C is formed in the same way as the rotary connection part recess 1A, but the rotary connection part recess 1C does not have an access hole and is, for example, provided in the second workpiece 2B, which is different in this respect. In this regard, the matters described above for the first type of rotary connection part recess also apply to the second type of rotary connection part recess, and the reference to the first workpiece surface 43A can be replaced by a reference to the first workpiece surface 43B.

[0083] The connecting part milling machine 10 is formed so as to form a rotary connection part recess 1C as the recess 1. In particular, the connecting part milling machine 10 has motion information for forming the rotary connection part recess, which is assigned to the rotary connection part recess 1C.

[0084] During the formation of the rotary connection part recess 1C, the connecting part milling machine 10 performs the forming act according to the motion information assigned to the rotary connection part recess 1C to be formed. At this time, according to the motion information, the milling tool 17 (which performs a cutting motion) is moved in the width direction x, the lateral direction y, and the depth direction z that define the recess geometry of the rotary connection part recess 1C.

[0085] Figures 12 to 16 show a workpiece arrangement structure 40 including a first workpiece 2A and a second workpiece 2B, and a connection part 53 configured as an exemplary motion mechanism connection part 53D.

[0086] The motion mechanism connection part 53D includes a coupling main body part 54 and an operation part 55 arranged on the coupling main body part 54 (supported movably relative to the coupling main body part, particularly rotatably supported). The operation part has, for example, a hexagonal recess, and a tool 56 configured as a hexagonal socket can be fitted into the recess. The motion mechanism connection part 53D further includes an engagement protrusion 57. The engagement protrusion 57 is arranged on the coupling main body part 54 and is supported movably relative to the coupling main body part. The engagement protrusion 57 is kinematically connected to the operation part 55 via, for example, one or a plurality of cam mechanisms so that the engagement protrusion 57 can be selectively displaced to an engagement position or an insertion position by the movement, particularly rotation, of the operation part 55. At the engagement position, the engagement protrusion 57 protrudes further from the coupling main body part 54 than the insertion position, particularly along the lateral direction y, and thus, for the purpose, in the positive and / or negative lateral direction y. Exemplarily, four engagement protrusions 57 are provided, and two engagement protrusions 57 are provided at each end of the motion mechanism connection part 53D located along the depth direction z. The engagement protrusions are spaced further apart from each other than the insertion position at the engagement position (particularly along the lateral direction y) for the purpose.

[0087] The first workpiece 2A has a first workpiece surface 43A, and on the first workpiece surface, a recess 1, that is, a movement mechanism connection portion recess 1E that partially houses the movement mechanism connection portion 53D, is provided illustratively. The movement mechanism connection portion recess 1E illustratively includes a connection portion hole 45 and an access hole 48. The first workpiece 2A further has a second workpiece surface 44A, and the second workpiece surface is illustratively oriented perpendicular to the first workpiece surface 43A of the first workpiece 2A and is connected to the first workpiece surface 43A of the first workpiece 2A particularly via a common edge 61 of the first workpiece 2A.

[0088] The second workpiece 2B has a first workpiece surface 43B, and on the first workpiece surface, a recess 1, that is, a movement mechanism connection portion recess 1F that partially houses the movement mechanism connection portion 53D, is provided illustratively. The movement mechanism connection portion recess 1F illustratively includes a connection portion hole 45 and particularly does not include an access hole 48. The second workpiece 2B further has a second workpiece surface 44B, and the second workpiece surface is illustratively oriented perpendicular to the first workpiece surface 43B of the second workpiece 2B and is connected to the first workpiece surface 43B of the second workpiece 2B particularly via a common edge 61 of the first workpiece 2B.

[0089] The workpiece arrangement structure 40 can be brought into an assembled state, in which the first workpiece 2A is, in particular, such that the second workpiece 2B is fixed to the first workpiece 2A in all spatial directions, and / or the second workpiece 2B abuts particularly flatly against the first workpiece surface 43A of the first workpiece 2A at its first workpiece surface 43B, and is connected to the second workpiece 2B via the motion mechanism connection part 53D. In the assembled state, the motion mechanism connection part 53D is fitted into the motion mechanism connection part recess 1E of the first workpiece 2A and the motion mechanism connection part recess 1F of the second workpiece 2B. For fitting the motion mechanism connection part 53D into both motion mechanism connection part recesses 1E, 1F, exemplarily, first, the engagement protrusions 57 are arranged at the insertion locations. Exemplarily, for fixing the second workpiece 2B to the first workpiece 1A, preferably, the tool 56 engages with the operation part 55 through the access hole 48 and rotates about a rotation axis extending parallel to the y direction, so that the operation part 55 is relatively operated, in particular rotated, with respect to the coupling main body part 54 in a state where the motion mechanism connection part 53D is fitted into the motion mechanism connection part recess 1E of the first workpiece 2A and the motion mechanism connection part recess 1F of the second workpiece 2B, so that at least one engagement protrusion 57, exemplarily two engagement protrusions 57, engages with the motion mechanism connection part recess 1E of the second workpiece 2A (particularly having the undercut 46), and at least one engagement protrusion 57, exemplarily two engagement protrusions 57, engages with the motion mechanism connection part recess 1F of the second workpiece 2B (particularly having the undercut 46).

[0090] The motion mechanism connection part recess 1E may also be referred to as the first type of motion mechanism connection part recess.

[0091] The recess 1E of the motion mechanism connection part preferably includes a connection part hole 45 having at least one undercut 46. Exemplarily, the connection part hole 45 is provided with two undercuts 46. Preferably, the connection part hole 45 includes a main part 64, and the main part is used to at least partially accommodate the connection part body 54. The undercut 64 opens only on the first workpiece surface 43A, particularly on the first workpiece surface 43A of the first workpiece 2A. The main part 64 has an exemplary cylindrical shape. In particular, the x-y cross-section of the main part 64 is constant along the cylindrical axis (exemplarily oriented parallel to the depth direction z). The main part 64 has an x-y cross-section, with which the main part 64 opens on the first workpiece surface 43A of the first workpiece 2A, and / or the outer contour of the x-y cross-section includes two straight parts 65 extending in parallel and a rounded, particularly arc-shaped end part 66 connecting the two straight parts 65. The x-y cross-section is configured to be elongated and, for the purpose, is oriented parallel to the width direction x by its longitudinal axis. Each undercut 46 has an exemplary linear extension. For the purpose, each undercut 46 is cylindrically configured with a cylindrical axis oriented parallel to the depth direction z. Preferably, each undercut 46 has a cross-section (particularly an x-y cross-section) configured to be parallel to the cylindrical axis of the main part 64 (e.g., parallel to the depth direction z), particularly in the shape of a polygon, such as a quadrilateral. For example, the cross-section is provided with one or more chamfers with respect to, for example, the connection part hole bottom 47 and / or the main part 64. In particular, each undercut 46 is configured as a recess, and the longitudinal axis of the elongated recess is oriented parallel to the width direction x. Exemplarily, the undercut 46 continues with the main part 45 in the positive lateral direction y, and another undercut 46 continues with the main part 45 in the negative lateral direction y. For the purpose, the interval between each undercut 46 with respect to the first workpiece surface 43 against which the connection part milling disk 10 abuts by the abutting structure 8 during the formation of the recess 1 is constant along the extension direction of the connection part hole 45 oriented perpendicular to the rotation axis of the cutting motion.The longitudinal direction is, for example, the width direction x. For the purpose, the intervals of the respective undercuts 46 with respect to the first workpiece surface 43A of the first workpiece 2A are constant over the (particularly overall) x extension of the movement mechanism connection part recess 1E. Optionally, the z extension (i.e., particularly the depth (depth)) of the connection part hole 45 is constant over the entire x extension of the connection part hole 45. The x extension is an extension in the width direction x.

[0092] The movement mechanism connection part recess 1E includes an access hole 48, which is configured, for example, in a cylindrical shape, and for the purpose, extends from the main part 45 along the lateral direction y to the second workpiece surface 44A of the first workpiece 2A and opens on the second workpiece surface. The cylindrical axis of the access hole 48 is oriented, for example, parallel to the y direction. For the purpose, the access hole 48 opens on the first workpiece surface 43A of the first workpiece 2A and penetrates, for example, the common edge 61 of the first workpiece 2A.

[0093] The connection part milling disk 10 is formed so as to form the movement mechanism connection part recess 1E as the recess 1. In particular, the connection part milling disk 10 has movement information for forming the movement mechanism connection part recess 1E, which is assigned to the movement mechanism connection part recess 1E.

[0094] During the formation of the movement mechanism connection part recess 1E, the connection part milling disk 10 performs a forming action according to the movement information assigned to the movement mechanism connection part recess 1E to be formed. At this time, according to the movement information, the milling tool 17 (executing a cutting movement) is moved in the width direction x, the lateral direction y, and the depth direction z that define the recess geometry of the movement mechanism connection part recess 1E.

[0107] The following describes a method for operating a handheld connection part milling machine, in particular the connection part milling machine 10 or the connection part milling machine 20.

[0108] The method includes a step of positioning the connection part milling machines 10, 20 relative to the workpiece 2 such that the connection part milling machines 10, 20 are statically abutted against the workpiece 2 by means of the abutment structure 8, in particular during the formation of the recess 1.

[0109] The method further includes controlling (operating) the electrical positioning device 18 according to motion information, in particular by the control unit 37, such that the electrical positioning device 18 brings the milling tool 17 into a motion sequence while the milling tool 17 performs a rotary cutting motion to form a recess 1 including a connection part hole 45 having a preset recess geometry, in particular according to the motion sequence (while the milling tool 17 performs a rotary cutting motion to form a recess 1 including a connection part hole 45 having a preset recess geometry, the electrical positioning device 18 brings the milling tool 17 into a motion sequence according to the motion sequence).

[0110] Preferably, the connection part milling machines 10, 20 are statically abutted against the workpiece 2 by means of the abutment structure, in particular simultaneously by both structure parts 9, 11, during the entire motion sequence. According to the motion sequence, the connection part hole 45 and also the access hole 48 are expediently formed. Preferably, no repositioning (position change) of the connection part milling machines 10, 20 is performed between the formation of the connection part hole 45 and the formation of the access hole 48 relative to the workpiece.

[0111] Preferably, the recess 1 includes a connection hole 45 that opens on the first workpiece surface 43 of the workpiece 2 and extends along the width direction x, and an access hole 48 that extends from the connection hole 45 along the transverse direction y perpendicular to the width direction x to the second workpiece surface 44 of the workpiece 2 and opens on the second workpiece surface. Preferably, the connection milling disks 10, 20 are statically in contact with the workpiece 2 simultaneously by both structural parts 9, 11 during the entire movement sequence of forming both the connection hole 45 and the access hole 48.

[0112] Preferably, the milling tool 17 moves through the axis of rotation 15 during the formation of the access hole 48.

[0113] Optionally, after the formation of the recess 1, the connection part 53 is fitted into the recess 1, particularly into the connection hole 45 of the recess 1, especially after the completion of the formation of the recess 1.

[0114] Optionally, the workpiece placement structure 30 or the workpiece placement structure 40 is formed by the workpiece 2 (as the first workpiece 2A).

[0115] Preferably, the connection milling disks 10, 20 do not require a drilling jig (especially for forming the access hole 48) to form the access hole 48 from the first workpiece surface 43. For example, a dowel milling disk or a router (especially as the connection milling disks 10, 20) is provided, and the access hole 48 (for example, a transverse groove) can be formed by the dowel milling disk or the router at a preset relative position with respect to the connection hole 45 (for example, configured as a connecting groove). Alternatively, it is possible to provide an industrial CNC milling disk to form the access hole 48 (especially a transverse groove) and the connection hole (especially a connecting groove).

[0116] For example, first, one of the first concave portions, particularly one of the concave portions 1 described above, is formed on the first workpiece surface 43 by the connecting portion milling machines 10 and 20, while the connecting portion milling machines 10 and 20 are statically abutted against the first workpiece surface 43 by the abutting device 6. Thereafter, the connecting portion milling machines 10 and 20 are manually repositioned (positioning change), for example, on the first workpiece surface 43 or another workpiece surface. Subsequently, a second concave portion is formed by the connecting portion milling machines 10 and 20, while the connecting portion milling machines 10 and 20 are statically abutted against the first workpiece surface or another workpiece surface by the abutting device 6. The second concave portion is particularly one of the concave portions 1 described above. The second concave portion is, for the purpose, different from the first concave portion. The second concave portion is formed on the first workpiece surface 43 or another workpiece surface.

[0117] Optionally, the first concave portion 1 and the second concave portion are the same. For example, the first concave portion and the second concave portion each include one connecting portion hole 45 and one access hole 48, respectively. For example, the first concave portion is formed on the first workpiece surface of the first workpiece, and the second concave portion is formed on the first workpiece surface of the second workpiece. For example, when forming the first concave portion, the connecting portion milling machines 10 and 20 are simultaneously abutted against the first workpiece surface and the second workpiece surface of the first workpiece by the abutting device 6, and the angle 12 is preferably greater than 90°. For example, when forming the second concave portion, the connecting portion milling machines 10 and 20 are simultaneously abutted against the first workpiece surface and the second workpiece surface of the second workpiece by the abutting device 6, and the angle 12 is preferably greater than 90°.
