- the hardware configuration of the tool path generation device 1 is such that a monitor 3 and a processing device 4 including a CPU 4a and a memory 4b are connected to a bus 2 including an address bus and a data bus. Further, an input device 5 including an operation keyboard and a mouse is connected.
- a computer program 10 shown in FIG. 2 is stored in the hard disk, RAM, and the like included in the memory 4b. The computer program 10 is operated by an instruction from the input device 5 and processed by the CPU 4a. The processing result is displayed on the monitor 3. The created data is input to the NC device 6 as CAM data, and cutting is performed.
- the program 10 implemented as the tool path generation device 1 is roughly configured by a machining condition setting unit 11, a contour line setting unit 12, a machining path generation unit 13, and an unmachined part.
- the update unit 14 and the connection path generation unit 15 are configured.
- the machining condition setting unit 11 generally includes a dimensional condition setting unit 11a, a tool movement limit line setting unit 11b, an initial unmachined part setting unit 11c, and a machining start path setting unit 11d.
- the machining path generation unit 13 includes a cutting path generation unit 13a and a return path generation unit 13b.
- the dimension condition setting unit 11a sets the pitch p (the amount of cutting in the tool radial direction with respect to the cutting part 101), the radius r2 of the return path 62, and the tool diameter d of the selected cutting tool T as cutting conditions. These are set by being input by the input device 5 and used for processing in the following units.
- the tool movement limit line setting unit 11b sets the tool movement limit line 30 by offsetting the machining range 20 based on the shape data of the cutting part 101 inward by the radius r1 of the tool T.
- the processing range 20 is shape data of the cutting part 101 extracted from the CAD data of the workpiece 100, and is a portion (region) to be cut from the raw material by cutting.
- the inside of the contour 102 (boundary line between the material and the space) in a plane orthogonal to the cutting depth (depth) of the tool T in the axial direction with respect to the cutting site 101.
- the region becomes the processing range 20.
- the tool movement limit line 30 is a line indicating an area where a machining path 60 (tool path TP) described later can be generated. Within this region, even if the tool T moves, it does not interfere with the product shape. Therefore, the tool T that moves on the generated machining path 60 does not interfere with the workpiece 100. Since the machining range 20 and the tool movement limit line 30 are determined based on the shape of the cutting site 101, they are not changed in the process of generating the tool path TP. For the opening 103, the machining range 20 may be offset to the outside of the machining range 20 by a tool radius r1 or more.
- the tool path TP is a trajectory along which the center of the tool T moves, and includes a machining start path 50, a machining path 60 (a cutting path 61 and a return path 62), and a connection path 70 that connects them.
- the initial unprocessed part setting unit 11c sets the above-described processing range 20 as the initial unprocessed part 40 '.
- the unprocessed portion 40 indicates a portion to be cut from now on in the processing range 20. That is, the initial unprocessed portion 40 ′ is the same as the processing range 20.

- the machining start path setting unit 11d generates a machining start path 50 for starting cutting with respect to the initial unmachined part 40 '.
- the cutting part 101 has a shape having an opening 103 in at least a part of the outer periphery in a plane orthogonal to the rotation axis of the tool T (FIG. 3A, open pocket), as shown in FIG.
- the contour line 41 ′ of the initial unmachined portion 40 ′ corresponding to the portion 103 is offset by the difference between the radius r1 of the tool T and the pitch p (cut amount), and the tool movement limit line 30 in the offset contour line 42 ′.
- a processing start path 50 is generated by extracting a portion 43 ′ located inside the machining center. Then, return paths 62 described later are given to both ends of the machining start path 50. Thereby, the tool T can be smoothly advanced along the opening 103, and an increase in the tool load is prevented.
- the contour line setting unit 12 sets the contour line 45 of the part that the tool T intends to cut from now on.
- the contour 45 is not the contour (entire circumference) of the unmachined portion 40 but a portion where the tool T enters the unmachined portion 40. That is, it is a boundary in the machining range 20 between a portion regarded as cut by the generated machining path 60 and a portion regarded as uncut.
- the contour 45 is newly obtained based on the updated unprocessed portion 40 every time the unprocessed portion 40 is updated by the unprocessed portion update section 14 described later.
- the machining path generation unit 13 generates a machining path 61 by generating a cutting path 61 inside the tool movement limit line 30 and giving arc-shaped return paths 62 to both ends of the cutting path 61.
- the cutting path 61 mainly indicates a path for cutting the cutting site 101
- the return path 62 mainly indicates a path for the tool to move from the cutting path 61 to the next cutting path 61. Since the machining path 60 is generated inside the tool movement limit line 30, the final shape of the workpiece 100 is not impaired. Further, there is no need to lift the tool T moving on the tool path TP, and the machining efficiency is good.
- the cutting path generator 13a offsets the contour line 45 by the difference between the radius r1 of the tool T and the pitch p, and the inside of the tool movement limit line 30 in the offset contour line 46. A portion 47 located at is extracted and a cutting path 61 is generated. The direction of the offset is the direction opposite to the direction D of cutting.
- the return path generation unit 13b gives arc-shaped return paths 62 to both ends of the generated cutting path 61 in a direction in which the contour line 45 is offset. As shown in FIG. 3C, the return path 62 is obtained as an arc that touches both the cutting path 61 and the tool movement limit line 30. This prevents a sudden path change in the tool path, smoothes the path, and suppresses an excessive increase in tool load.
- the return path 62 ′ when the return path 62 ′ cannot be given to the next cutting path 61 ′ within the tool movement limit line 30, the return path 62 ′ is set to be within the tool movement limit line 30.
- the radius r2 of the return path 62 ′ is reduced.
- the next cutting path 61 ′ has been obtained based on the unmachined portion 40, but the radius r 2 of the set return path 62 is large, so the return path 62 is changed to the next cutting path 61. Cannot be granted to '. Therefore, the return path radius r2 is reduced so that the return path 62 is within the tool movement limit line 30 as shown in FIG.
- the unmachined portion 40 can be updated based on the generated machining path 60, the remaining portion of cutting is reduced, and machining efficiency is improved.
- the unmachined part update unit 14 removes the tool movement area W formed by the movement of the tool T according to the machining start path 50 or the machining path 60 from the unmachined part 40 in the machining range 20 and updates the unmachined part 40. To do. Thereby, the updated unprocessed portion 40 indicates an area to be cut after the next processing pass 60. That is, the unmachined portion 40 does not include a cut (machined) portion, and the next machining pass 60 is generated based on the unmachined portion 40, so that it is possible to prevent the machining twice. .
- connection path generation unit 15 generates a connection path 70 that connects the generated processing path 60 to the processing path 60 generated immediately before.
- This connection path 70 is connected to the return path 62 of the machining path 60 and the next path so that the traveling direction of the tool T of the cutting path 61 of the machining path 60 generated immediately before and the cutting path 61 of the machining path 60 generated immediately before are the same. It is generated as a line segment connecting the return path 62 of the machining path 60. As shown in FIG. 3C, in the present embodiment, this line segment is further obtained as a return path 62 of the machining path 60, a return path 62 of the next machining path 60, and a tangent line that touches both arcs.
- connection path can connect the machining paths with the shortest distance, and is efficient.
- connection path 70 may be extended outside the tool movement limit line 30.
- a connection path 70 is generated from the return path 62 on the left side of the drawing to the outside of the tool movement limit line 30 and connected to the return path 62 on the right side of the drawing.
- the extension path 71 a is corrected along the tool movement limit line 30 to generate the detour line 71.
- the connection path 70b of the interference portion is corrected so as to be along the detour line 72 offset from the unmachined portion 40 by the radius r1 of the tool T.

And a processing path generation step S6 and a connection path generation step S7.

This is set (FIG. 8a (e)). Then, the machining path generation unit 13 offsets the contour line 45 obtained by the contour line setting unit 12 by the difference between the tool radius r1 and the pitch p, and the tool movement limit line setting unit 11b sets the offset contour line 46. The portion 47 located inside the tool movement limit line 30 is extracted (calculated). If the portion 47 cannot be extracted (FIG. 8b (j), step S5), the machining path generated and connected so far is output as the tool path TP (FIG. 8b (k), step S8).
- the machining path generation unit 13 In the machining path generation step S6, the machining path generation unit 13 generates the portion 47 extracted in the previous unmachined part outline setting step S4 as the cutting path 61 (FIG. 8a (f)) and at both ends of the cutting path 61.
- An arcuate return path 62 is provided to generate a machining path 60 (FIG. 8b (g)).
- the return path generator 13b adjusts the return path radius r2.
- the generated machining path 60 is set as the current machining path.
- connection path generation unit 15 generates a connection path 70 that connects the current processing path 60 generated by the processing path generation unit 13 and the processing path 60 generated immediately before it, These machining paths 60 are connected (FIG. 8b (g)).
- connection path 70 of the part is corrected.
- the unprocessed portion 40 is generated separately in the process of generating the tool path TP.
- the unprocessed portion 40 is generated separately (FIGS. 9a (b) and (c)). Therefore, one of the offset contour lines 46 is selected, and the process is continued for one unprocessed portion 40a (FIG. 9b (d)).
- the process proceeds to the other unprocessed portion 40b (FIG. 9b (f)).
- connection path 70 is corrected so as to avoid the intersection with the tool movement limit line 30 and the tool interference with the unmachined portion 40 (FIG. 9b (g)).
- the connection path 70 is corrected so as to avoid the intersection with the tool movement limit line 30 and the tool interference with the unmachined portion 40 (FIG. 9b (g)).
- the generation of the tool path TP when the cutting site 101 is an open pocket has been described.
- the outer periphery of the plane orthogonal to the rotation axis of the tool T may be closed (closed pocket).
- it has the introduction part 104 which introduces the tool T (FIG. 10a (a)).
- the machining start path generation unit 11 c forms a spiral 51 that spreads outward at a pitch p from the portion 41 ′ of the initial unmachined portion 40 ′ corresponding to the introduction unit 104 to the tool movement limit line 30. It is generated as a machining start path 50 (FIGS. 10a (b) to (d)). Similarly, the return path 62 is also given to the spiral 51 (FIG. 10a (e)).
- reference numeral 45 ′ indicates a circle whose radius is a length obtained by adding a tool radius r 1 to a straight line from the center to the tip of the spiral 51.
- the later-described unmachined part update unit 14 updates the initial unmachined part 40 ′, and the later-described machining path generation unit 13 creates the next machining path (FIG. 10a (f)). ). If a plurality of offset contour lines 46 are generated, one of the contour lines 46 is selected in the same manner as described above. In the example of the figure, the offset outline 46 on the upper side of the drawing is selected, and the processing is continued in the same manner as in the above embodiment (FIGS. 10b (g) to (j)). In this example, the radius r2 of the return path 62 is adjusted as shown in FIG.
- the generation of the tool path TP in the substantially rectangular machining range 20 has been described, but the shape is merely an example.
- the shape of the machining range 20 (the shape of the cutting part 101) is not limited, and the tool path TP can be similarly generated even in the machining range 20 having an indefinite shape.
- the spiral 51 that spreads outward at the pitch p is generated as the machining start path 50.
- the present invention is not limited to this, and it is also possible to generate the spiral 51 extending inward as the machining start path 50 according to the shape. As described above, the present invention can be carried out regardless of the shape of the machining range 20 (the cutting portion 101).
- the tool movement limit line 30 is set by offsetting the machining range 20 inward by the radius r1 of the tool T.
- the present invention is not limited to this.
- an offset corresponding to the finishing margin for the subsequent process may be used.
- a computer program that causes a computer to function as a tool path generation device is stored in the memory 4b, and the CPU 4a executes the program.
- the program and data may be stored in an external storage device such as a magnetic disk device or an optical disk device, and loaded into the memory 4b for execution. It is also possible to record the program and data on a computer-readable recording medium and execute the program via a reading device. Examples of the recording medium include optical disks such as CD-ROM, DVD, and Blu-ray (registered trademark), magneto-optical disks, flash memories such as USB memory and SD card, and the like.
