Description

The present invention relates to a data generating device, processing device, a 及 Beauty data generation program.

  As a processing apparatus for cutting a plurality of parts from a plate material that is a workpiece, for example, a numerically controlled (NC) laser processing machine, a punch press, and the like are known. These laser processing machines or the like cut a periphery of a desired part from a plate material and cut out a plurality of parts. The NC data used for numerical control in a laser processing machine or the like is, for example, the relationship between the position of the processing line for cutting out each part and the processing timing.

  Further, a technique has been proposed in which a plurality of parts are efficiently cut out by overlapping processing lines for cutting out parts from a plate material with adjacent parts (for example, see Patent Document 1 below). When processing lines are overlapped with adjacent parts, NC data is generated using, for example, peripheral data of each part arranged in the plate material in order to determine the processing timing. For example, if the outer periphery of some parts is cut first, this part may come off the plate, which may affect other parts, so the outer periphery that combines adjacent parts The processing order is determined so that the processing line is cut last.

Japanese Patent No. 3204161

  When processing lines are overlapped with adjacent parts, this common processing line corresponds to a boundary line between the parts, and is expressed in a state branched from a processing line on the entire outer periphery in which a plurality of parts are combined. Therefore, in order to automatically discriminate the entire outer peripheral machining line with a computer or the like, for example, it is necessary to perform a determination process such as finding the entire outer peripheral machining line while switching the branched machining lines. As the number of lines increases, processing and algorithms become complicated. In addition, the operator can manually specify the processing line on the entire outer periphery, but it is necessary to specify it appropriately while looking at the plurality of arranged parts. This increases the burden on the operator.

The present invention has been made in view of the circumstances described above, automatically and data generating apparatus capable of easily obtaining the outer periphery data having a shape arranged to overlap the processing line in the adjacent parts,及 Beauty data An object is to provide a generation program. Moreover, it aims at providing the processing apparatus which can cut out several components efficiently from a board | plate material.

The data generation apparatus of the present invention is a common processing line that overlaps the adjacent parts with the data acquisition unit that acquires the composite shape data of the plurality of parts that are overlapped with the adjacent parts. A shape data generation unit that generates outer data of a virtual shape obtained by removing the processing line from the composite shape data.

  The data acquisition unit may generate composite shape data based on component data that defines the shapes of a plurality of components. In addition, the shape data generation unit may generate outer periphery data from a closed processing line detected from the virtual shape. Further, when a plurality of closed processing lines are detected, the shape data generation unit may generate virtual shape inner peripheral data from closed processing lines other than the outer peripheral data. Moreover, you may provide the process data generation part which produces | generates the process data which defined the order which processes a process line including the common process line removed by the shape data generation part. In addition, the processing data generation unit may define the order of processing the processing lines of the outer periphery data in an order after the order of processing the common processing lines. Further, the processing data generation unit may define the order of processing the processing lines of the outer periphery data in the last order.

  Moreover, the processing apparatus of this invention cuts out several components from a board | plate material based on the data produced | generated by said data production | generation apparatus.

Further, the data generation program of the present invention acquires, in a computer, composite shape data obtained by superimposing processing lines for cutting out a plurality of parts from a plate material on adjacent parts , and a common processing that is a processing line overlapping on adjacent parts. Generating virtual shape outer periphery data by removing the line from the composite shape data.

  A data generation device, a data generation method, and a data generation program according to the present invention generate virtual shape outer periphery data obtained by removing common machining lines from composite shape data. The outer periphery of the virtual shape is the same as the outer periphery of the composite shape, but it is easy to discriminate because there is no branching with the common processing line, and the peripheral data of the composite shape is automatically and simply based on the outer periphery of the virtual shape Can be obtained. Moreover, since the processing apparatus which concerns on this invention operate | moves based on said data, it can cut out several components from a board | plate material efficiently.

  In addition, the data acquisition unit generates composite shape data based on part data that defines the shape of each of a plurality of parts, and can generate peripheral data of the composite shape from the part data. Is expensive. In addition, the shape data generation unit, which generates the outer periphery data from the closed machining line detected from the virtual shape, can easily detect the outer periphery of the composite shape, so the processing and algorithm of the data generation device is simplified. Can be. In addition, when a plurality of closed machining lines are detected, the shape data generation unit generates virtual shape inner circumference data from closed machining lines other than the outer circumference data. Since it can be used for processing, it is highly convenient.

  In addition, including a common processing line removed by the shape data generation unit, including a processing data generation unit that generates processing data that defines the order in which processing lines are processed, for example, a plate material is processed based on the processing data Can be highly convenient. In addition, the processing data generation unit defines the order of processing the processing line of the outer periphery data in the order after the processing order of the common processing line. For example, the processing data generation unit is common in a state where the parts are not separated from the plate material. The machining line can be machined, and the positional deviation during machining of the common machining line can be suppressed. In addition, if the processing data generation unit defines the processing order of the processing line of the outer periphery data in the last order, for example, the component is separated from the plate material by the last processing, so the positional deviation at the time of processing Can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to this. Further, in the drawings, in order to describe the embodiment, the scale is appropriately changed and expressed by partially enlarging or emphasizing the description. In the following drawings, directions in the drawings will be described using an XYZ coordinate system. In this XYZ coordinate system, a plane parallel to the horizontal plane is defined as an XZ plane. An arbitrary direction parallel to the XZ plane is expressed as a Z direction, and a direction orthogonal to the Z direction is expressed as an X direction. The direction perpendicular to the XZ plane is denoted as the Y direction. In each of the X direction, the Y direction, and the Z direction, the direction of the arrow in the figure is the + direction, and the direction opposite to the arrow direction is the − direction.

  FIG. 1 is a diagram illustrating a data generation device 1 and a processing device 2 according to the present embodiment. The processing apparatus 2 is a laser processing machine, for example, and can cut the plate material W. As shown in FIG. 1, the processing apparatus 2 includes, for example, a processing pallet 3, a light source unit 4, a laser head 5, a drive unit 6, and a control unit 7. The processing pallet 3 is formed, for example, in a state where a plurality of support plates 3a stand on a rectangular plate-shaped base. The plurality of support plates 3a are arranged side by side in the X direction, and each upper end is formed in a sawtooth shape. The plate material W as a workpiece is placed on a plurality of support plates 3a and supported along a horizontal plane (XY plane).

  Further, the processing pallet 3 is formed to be movable in the X direction, for example, by a driving device (not shown). In the processing pallet 3, for example, an unprocessed plate material W is placed at a position away from the processing device 2, and the plate material W can be carried into the processing device 2 by moving while the plate material W is placed. The processing of the plate material W by the laser head 5 is performed while being placed on the processing pallet 3. The processed plate material W is unloaded from the processing apparatus 2 by moving the processing pallet 3 while being placed on the processing pallet 3. In addition, the above-described processing pallet 3 is an example, and other forms may be used. For example, instead of the sawtooth support plate, a support plate having a corrugated upper end may be used, and a plurality of pins may be formed on the base of the processing pallet 3 and the plate material W may be supported by the upper ends of these pins. .

  The light source unit 4 is a fiber laser, for example, and generates a laser beam LB. The laser beam LB from the light source unit 4 is introduced into the laser head 5 through the optical fiber 8 or the like. The laser head 5 can be arranged above the processing pallet 3 (Z direction). The laser head 5 has an optical system (not shown) that condenses the laser beam LB from the light source unit 4 on the plate material W, and irradiates the plate material W with the laser beam LB. The drive unit 6 can move the laser head 5 in the horizontal direction (X direction, Y direction) and the vertical direction (Z direction).

  For example, the processing device 2 cuts the plate material W by numerical control (NC) using processing data (processing recipe). The machining data is, for example, NC data that defines a machining line (cutting line) position and machining timing (machining order) for cutting out a part. The control unit 7 controls the light source unit 4 and the drive unit 6 based on the processing data. The control unit 7 controls lighting, extinction, output, and the like of the light source unit 4. For example, the controller 7 causes the laser head 5 to emit the laser beam LB by turning on the light source unit 4. The control unit 7 controls the position of the laser head 5 by controlling the drive unit 6. The control unit 7 moves the laser head 5 by the driving unit 6 while irradiating the laser beam LB from the laser head 5 according to the processing data, and cuts the plate material W.

  The data generation device 1 generates data used for numerical control of the processing device 2. For example, the data generation device 1 generates machining data used for machining a plurality of parts Xa to Xd from the plate material W. For example, the data generation device 1 acquires part data that defines the shape of each of the plurality of parts Xa to Xd from a design apparatus 9 such as a CAD system, and generates machining data based on the part data. The data generation device 1 may supply the processing data to the processing device 2 by wired or wireless communication, or the user may store the processing data in a USB memory or the like and supply the processing data to the processing device 2. The processing data includes the material of the plate material W to be processed, the plate thickness, the processing speed (moving speed of the laser head 5), the output of the laser beam LB, the spot diameter of the laser beam LB, the nozzle used for the laser head 5, Data such as the type and supply amount of assist gas used during laser processing may be included.

  FIG. 2A is a diagram illustrating a configuration of the data generation apparatus 1 according to the present embodiment, and FIGS. 2B to 2D respectively illustrate component data D1, composite shape data D2, and virtual shape data D3. FIG. In FIGS. 2B to 2D, the shape (component shape) defined in the component data D1 is represented by the symbol F1, the shape (composite shape) defined in the composite shape data D2 is represented by F2, and the virtual shape data The shape defined in D3 (virtual shape) is represented by the symbol F3. The component data D1 described above is different data for each shape of the component, and is not limited to the illustrated shape data.

  The data generation device 1 includes a data acquisition unit 11, a shape data generation unit 12, and a machining data generation unit 13. The data acquisition unit 11 acquires the composite shape data D2 of FIG. For example, the data acquisition unit 11 acquires the composite shape data D2 by generating the composite shape data D2 based on the component data D1 of FIG.

  The component data D1 in FIG. 2B is of a cross-shaped component shape F1. The component data D1 includes, for example, the coordinates of each of a plurality of vertices (for example, the vertex Ta and the vertex Tb) of the component, and vertex connection information. The connection information represents, for example, whether or not a component edge (side) exists between the vertices depending on whether or not the vertices are connected. For example, the line connecting the vertex Ta and the vertex Tb is the edge E of the part, and the connection information defines that the vertex Ta and the vertex Tb are connected, so that the vertex Ta and the vertex Tb are connected. This means that there is an edge E between them.

  The composite shape data D2 in FIG. 2C is data representing the overall shape of a plurality of components obtained by overlapping machining lines for cutting out the plurality of components Xa to Xd from the plate material W with adjacent components. The machining line is set at the same position as the edge of the component when the cutting width is negligible with respect to manufacturing tolerances, such as laser machining. In the following description, it is assumed that the processing line is at the same position as the edge of the component. For example, the data acquisition unit 11 determines the arrangement of a plurality of parts Xa to Xd by nesting processing, and at that time, a processing line between adjacent parts (hereinafter, referred to as a common processing line E1) includes a “common processing line”. Assign attribute information. The composite shape data includes, for example, the positions of all the processing lines of the composite shape and attribute information indicating whether each processing line is a common processing line.

  The shape data generation unit 12 generates outer periphery data D4 representing the outer periphery of the virtual shape F3 (see FIG. 2D) obtained by removing all the common processing lines E1 from the composite shape F2. For example, the shape data generation unit 12 acquires the composite shape data D2 from the data acquisition unit 11, removes the processing line having the attribute information “common processing line” from the composite shape F2, and obtains the virtual shape F3. Further, the shape data generation unit 12 detects a closed processing line E2 from the virtual shape F3, and generates outer periphery data D4 representing the position of the detected closed processing line E2. The outer periphery of the virtual shape F3 is the same as the outer periphery of the composite shape F2 (see FIG. 2C). However, since the branch from the common processing line E1 is eliminated, the processing line E2 is closed and simple processing is performed. Can be detected.

  When a plurality of closed processing lines E2 and E3 are detected from the virtual shape F3, the shape data generation unit 12 determines one of the plurality of closed processing lines E2 and E3 (closed processing line E2) as the virtual shape F3. The other closed machining line E3 is determined as the inner periphery (also referred to as a window) of the virtual shape F3. The inner circumference of the virtual shape F3 is the same as the inner circumference of the composite shape F2, but it can be detected by simple processing because there is no branching with the common processing line E1. The shape data generation unit 12 generates inner circumference data D5 representing the position of the inner circumference of the virtual shape F3.

  FIGS. 3A and 3B are diagrams showing examples of processing for determining the outer periphery and inner periphery of the virtual shape, respectively. In the process of FIG. 3A, for example, the shape data generation unit 12 calculates the area of the region surrounded by the closed processing lines for each of the plurality of closed processing lines E2 and E3, and sets the area of the maximum area. The corresponding closed processing line is determined as the outer periphery of the virtual shape. For example, since the area of the area AR1 surrounded by the closed processing line E2 is larger than the area of the area AR2 surrounded by the closed processing line E3, the shape data generation unit 12 determines the closed processing line E2 as the outer periphery. Then, the closed processing line E3 is determined as the inner periphery.

  In the process of FIG. 3B, the shape data generation unit 12 calculates intersections Cp1 to Cp4 between an arbitrary straight line L1 crossing the virtual shape F3 and the closed processing lines E2 and E3. The shape data generation unit 12 determines the closed processing line E2 to which the intersection points Cp1 and Cp4 located on the outermost side on the straight line L1 among the intersection points Cp1 to Cp4 belong to the outer periphery of the virtual shape F3. In addition, the shape data generation unit 12 determines a closed processing line E3 other than the closed processing line E2 determined for the outer periphery as the inner periphery of the virtual shape F3. There may be a case where it intersects with the closed machining line E2 and does not intersect with the closed machining line E3 as in the case of the straight line L2, but in this case, the closed machining line E2 to which the intersection points Cp5 and Cp6 with the straight line L2 belong is assumed to be a virtual shape F3. And the other closed processing line E3 may be determined as the inner periphery of the virtual shape.

  For example, the shape data generation unit 12 generates, as outer periphery data, the attribute information of the “outer periphery” added to each processing line included in the closed processing line E2 corresponding to the determined outer periphery. Similarly, the shape data generation unit 12 generates, as inner circumference data, the attribute information of “inner circumference” added to each machining line included in the closed machining line E3 corresponding to the determined inner circumference.

  The processing data generation unit 13 (see FIG. 2) generates processing data that defines the processing line processing order including the common processing line E1 removed by the shape data generation unit 12. For example, attribute information of “common machining line”, “outer circumference”, or “inner circumference” is given to the machining line, and the machining data generation unit 13 generates machining data with reference to the attribute information, for example. .

  4A is a diagram conceptually showing the processing data D6, and FIGS. 4B to 4D are diagrams showing processing corresponding to the processing data. The processing data D6 includes, for example, information on a process number, a cutting start position, and a cutting end position. The process number is a number indicating the order in which processing (cutting) is performed, and is assigned as 1, 2,..., N in the order in which cutting is performed first. The cutting start position and the cutting end position are the start point and end point of the processing line, respectively, and correspond to the position of the laser head 5 in FIG. In the processing data D6 of FIG. 4A, the reference numerals corresponding to FIGS. 4B to 4D are written in the cutting start position and the cutting end position. In FIG. 4A, the number (ID) and attribute information of the processing line processed in each process are shown for reference.

  The process numbers 1 to 4 correspond to FIG. 4B, and the common process line E1 is processed. In process number 1, the laser head 5 is moved by the drive unit 6 (see FIG. 1) to cut from the position P1 to the position P2 of the plate material W in FIG. 4B, and the machining line E1a among the common machining lines E1. Is processed. The process number 2 cuts from the position P3 to the position P4, and processes the processing line E1b of the common processing line E1. Cut from position P5 to position P6 in process number 3 to process the machining line E1c of the common machining line E1. The process number 4 cuts from the position P7 to the position P8, and processes the processing line E1d of the common processing line E1.

  Process numbers 5 to 8 correspond to FIG. 4C, and process the closed processing line E3 (inner circumference). In step number 5, the plate material W in FIG. 4B is cut from position Q1 to position Q2, and the processing line E3a is processed out of the closed processing line E3. The process number 6 cuts from the position Q2 to the position Q3, and processes the processing line E3b of the closed processing line E3. Cut from position Q3 to position Q4 in process number 7, and process line E3c of closed process line E3 is processed. The process number 8 cuts from the position P7 to the position P8, and processes the processing line E3d of the closed processing line E3. When the process numbers 5 to 8 are performed, a portion (end material) surrounded by the closed processing line E3 is cut off from the plate material W. If the processing of the common processing line E1 is finished before such end material is generated, the end material does not hinder the processing.

  The process numbers 9 to n correspond to FIG. 4D, and the closed processing line E2 (outer periphery) is processed. In the process number 9, it cut | disconnects from position R1 to position R2 of the board | plate material W of FIG. 4 (B), and processes the process line E2a among the closed process lines E2. Similarly, the machining lines included in the closed machining line E2 are cut in order, and cut from the position Rn to the position R1 at the process number n, and the machining line E2n of the closed machining line E2 is machined. When the process numbers 9 to n are performed, the plurality of parts Xa to Xd surrounded by the closed processing line E2 are separated from the plate material W. In this way, the processing data generation unit 13 determines, for example, the processing order of the processing line of the peripheral data (processing line with the attribute information “periphery”), the processing of the common processing line E1 (attribute information “common processing line”). (Line) is defined in the order after the order of processing (eg, last).

  In FIG. 4, after all the common processing lines E1 are processed, the processing lines E3a to E3d belonging to the closed processing line E3 (inner circumference) are processed, but at least part of the processing lines E3a to E3d. May be performed before the machining of the common machining line E1 is completed. Further, in FIG. 4, after the processing of all the processing lines E3a to E3d belonging to the closed processing line E3 (inner circumference) is completed, the processing lines E2a to E2n belonging to the closed processing line E2 (outer periphery) are processed. However, part of the machining lines E2a to E2n may be performed before the machining of the common machining line E1 is completed or before the machining of the machining lines E3a to E3d is completed.

  Note that at least one of the processing line number and the attribute information in FIG. 4A may or may not be included in the processing data D6. The processing data D6 may include information on the cutting speed (for example, the speed of the laser head 5) and the output of the laser beam LB for each processing of one process number or in common for processing of a plurality of process numbers. Further, the processing order may be defined by the time at which each processing is performed.

  Next, a data generation method will be described based on the configuration of the data generation device 1 shown in FIG. FIG. 5 is a flowchart showing a data generation method according to the present embodiment. In step S1, the data acquisition unit 11 acquires composite shape data D2. For example, in step S10, the data acquisition unit 11 acquires component data D1. In step S11, the data acquisition unit 11 arranges a plurality of components on the data by overlapping the processing lines with the adjacent components. In step S <b> 12, the data acquisition unit 11 generates composite shape data D <b> 2 including the processing line position and the “common processing line” attribute information for the plurality of arranged components.

  Next, in step S2, the shape data generation unit 12 generates outer periphery data D4 of the virtual shape F3. For example, in step S21, the shape data generation unit 12 calculates a virtual shape F3 by removing the common processing line E1 from the composite shape F2. In step S22, the shape data generation unit 12 detects a closed processing line from the virtual shape F3. In step S23, the shape data generation unit 12 determines whether or not the number of closed processing lines is one.

  If the shape data generation unit 12 determines that the number of closed processing lines is one (step S23; Yes), in step S24, the shape data generation unit 12 generates outer peripheral data D4 indicating the detected closed processing lines. If the shape data generation unit 12 determines that there are a plurality of closed processing lines (step S23; No), the shape data generation unit 12 determines the outer periphery from the plurality of closed processing lines in step S25. The shape data generation unit 12 generates the outer periphery data D4 in step S24 based on the closed processing line determined on the outer periphery. In step S26, the shape data generation unit 12 determines a closed processing line other than the outer periphery as the inner periphery. In step S27, the shape data generation unit 12 generates inner circumference data D5.

  Next, in step S3, the processing data generation unit 13 generates processing data. A plurality of parts Xa to Xd are manufactured (formed) by numerically controlling the processing device 2 using the processing data generated in this manner and processing the plate material W, for example.

  The above-described data generation device 1 has a form in which, for example, a computer performs various processes according to a data generation program. This data generation program is stored in, for example, a storage device such as a hard disk provided in the computer, and the computer reads the data generation program from the storage device and executes processing. This data generation program obtains a composite shape data of a plurality of parts obtained by superimposing a processing line for cutting out a plurality of parts from a plate material on a computer, and a processing line between adjacent parts. Generating virtual shape outer periphery data excluding the processing line from the composite shape. This data generation program may be provided by being recorded on a storage medium such as a computer-readable USB memory or CD-ROM.

  In the above-described embodiment, the cutting width by the laser processing machine is assumed to be sufficiently small, and the processing line is made to coincide with the edge (side) of each component. The width may not be negligible for manufacturing tolerances. Similarly, also in a laser beam machine, the cutting width increases when the spot diameter of the laser beam LB to be used is large. In such a case, the processing line may be determined in consideration of the cutting width. That is, in this specification, the common processing line is used in the meaning including a processing line having a predetermined interval in consideration of the cutting width.

  FIG. 6 is a diagram illustrating a process of generating outer periphery data in consideration of the cutting width. In FIG. 6A, reference numeral A1 indicates a processing region (margin) that is removed from the plate material W by cutting. The processing area A1 is provided with a cutting width B along the edge of the part Xa. In such a case, for example, the processing line Ec is set on the center line of the processing area A1.

  As shown in FIG. 6B, when a plurality of parts Xa to Xd are arranged on the data so that the machining lines Ec overlap with each other (eg, part Xa and part Xb), composite shape data D2 is obtained. can get. Further, when the common machining line E1 is excluded from the composite shape data D2, as shown in FIG. 6C, virtual shape data D3 is obtained. Further, the outer circumference data D4 is obtained by detecting the closed processing line E2 from the virtual shape F3.

  Further, the inner circumference data D5 is obtained by obtaining a closed machining line E3 other than the outer circumference among the plurality of closed machining lines E2 and E3 detected from the virtual shape F3. Further, using the data of the common machining line E1, the outer circumference data D4, the inner circumference data D5, etc., the machining data can be generated. When such machining data is used, for example, when the cutting blade is aligned with the machining line Ec and the machining area A1 is punched, edges of adjacent parts (eg, part Xa, part Xb) are collectively formed. The plurality of parts Xa to Xd can be efficiently cut out.

  In addition, although demonstrated as what the processing apparatus 2 is a laser processing machine in FIG. 1, the processing apparatus 2 may be a punch press etc. which can cut | disconnect the board | plate material W with a cutting blade, and the composite of a laser processing machine and a punch press. It may be a machine. For example, a part of the processing line may be processed by a laser processing machine, and another processing line may be processed by a punch press. For example, the common processing line E1 may be processed by a laser processing machine, and the inner peripheral processing line (closed processing line E3) and the outer peripheral processing line (closed processing line E2) of the composite shape may be processed by a punch press. .

  Note that the shape and number of parts can be changed as appropriate. FIGS. 7A to 7D are diagrams conceptually showing examples of outer periphery data generated from component data. In FIG. 2 and the like, the composite shape data D2 has one inner circumference, but may not have an inner circumference or may have two or more inner circumferences.

  The part data D1 in FIG. 7A is an L-shaped part, and composite shape data D2 is obtained by arranging the processing lines in an overlapping manner. The composite shape F2 has a cross shape and has no inner periphery. Also for such composite shape data D2, a virtual shape F3 is obtained when the common processing line E1 is excluded. Moreover, the outer periphery data D4 of the virtual shape F3 can be generated by detecting the closed processing line E2 in the virtual shape F3.

  The part data D1 in FIG. 7B is a C-shaped part, and composite shape data D2 is obtained by arranging the processing lines in an overlapping manner. The composite shape F2 has a rectangular outer shape and has two rectangular inner peripheries. For the composite shape data D2 having such a shape, a virtual shape F3 is obtained when the common processing line E1 is excluded. Moreover, the outer periphery data D4 of the virtual shape F3 can be generated by detecting the closed processing line E2 in the virtual shape F3. Further, in the virtual shape F3, a closed processing line E3 other than the outer periphery can be determined as the inner periphery, and the inner periphery data D5 of the virtual shape F3 can be generated.

  Further, in FIG. 2, the plurality of components Xa to Xd have one type of shape, but may have two or more types. In FIG. 7C, component data D10 for an L-shaped component, component data D11 for a triangular component, and component data D12 for a rectangular component are used. Using such a plurality of types of component data D11 to D12, composite shape data D2 is obtained by arranging the processing lines in an overlapping manner. For the composite shape data D2 having such a shape, a virtual shape F3 is obtained when the common processing line E1 is excluded. Moreover, the outer periphery data D4 of the virtual shape F3 can be generated by detecting the closed processing line E2 from the virtual shape F3.

  In addition, the component data D21 to D24 in FIG. 7D are for components having a shape including a curve on the outer periphery. For such component data D21 to D24, composite shape data D2 can be obtained by arranging the processing lines in an overlapping manner. For the composite shape data D2, the virtual shape F3 is obtained by removing the common processing line E1 from the composite shape F2. Moreover, the outer periphery data D4 of the virtual shape F3 can be generated by detecting the closed processing line E2 from the virtual shape F3.

  Note that the data generation device 1 does not have to perform the process of generating the composite shape data from the component data. For example, the design device 9 may generate composite shape data, and the data acquisition unit 11 may acquire the composite shape data from the design device 9. Moreover, the data generation apparatus 1 does not need to perform the process which produces | generates process data. For example, the data generation device 1 may output at least outer circumference data to an external device, and the external device may generate machining data using the outer circumference data. The data generation device 1 may be provided in the design device 9 or may include at least a part of the design device 9.

  Although the embodiments have been described above, the technical scope of the present invention is not limited to the aspects described in the above-described embodiments. In addition, one or more of the requirements described in the above-described embodiments may be omitted. In addition, the requirements described in the above-described embodiments and the like can be appropriately combined with other configurations.

  In the above-described embodiment, the processing apparatus 2 processes the plate material W by moving the laser head 5 with respect to the plate material W, but is not limited thereto. For example, the laser head 5 is fixed and the plate material W (processing pallet 3) is moved to process the plate material W, or both the laser head 5 and the plate material W are relatively moved to process the plate material W. Good.
