Description

  The present invention relates to a nesting device that arranges component graphics with respect to graphics of a material plate material in an automatic programming device or the like of a machining program for controlling a punch press machine.

  When a component plate material is cut out from a material plate material by a punch press, the processing is performed by repeating punch processing while shifting the punch position along the outer periphery of the component plate material. As a form of such a cutting process, as shown in FIG. 7, the adjacent side common form processing without opening a space between the adjacent component plate materials MR, and the interval between the component plate materials MR as shown in FIG. There is an interval giving form that can be opened.

  In any case, in the nesting of the automatic programming process, the part figure M, which is a figure provided with the tool placement portion Mt around the part board material MR, is arranged with respect to the figure W of the material board material. However, in the adjoining side common form of FIG. 7, one or two sides of the component plate material MR are shared with the outer periphery of the material plate material or the previously cut out side, and in the component plate material MR to be processed later, the common side is used. c is not processed. Therefore, it is assumed that no tool is arranged in the part figure M for the common side c that is not processed.

  The adjacent side common form as shown in FIG. 7 has an advantage that the yield is good because there is no space between the component plate materials MR. However, there is a problem that it takes time to crush the end material. That is, an end material portion S in which another component plate material MR cannot be disposed is generated between the component plate material MR and the outer periphery of the material plate material W or between adjacent component plate materials MR. This end material portion S is crushed into fine debris by punching only when it cannot be carried out. As a result, the end material is only in the vicinity of the gripping side WRa gripped by a work holder (not shown) of the punch press machine, so that the end material can be easily carried out. However, the crushing of the end material portion S requires repeated punching operations many times, so that a long time is required for processing and productivity is lowered. In addition, since the number of punches for crushing is large, the consumption of the punching tool for crushing is severe.

  In the form of providing a spacing as shown in FIG. 8, each component plate material MR is cut out from the material plate material WR, and a skeleton-like end material in which the cut-out holes are connected by a cross-shaped portion Q is generated. This skeleton-like end material is carried out by an unloader or an operator. Therefore, crushing is unnecessary and processing time is short. However, there is a drawback that the yield is poor. In addition, when the width of the cross-shaped portion Q generated between the cutout holes of the material plate material WR or between the outer periphery is narrow, the rigidity of the skeleton-shaped end material becomes low, and a material guide brush on the work table or the like The ball may get caught and processing may not be stable. As described above, both of the adjacent side commoning form and the spacing providing form have advantages and disadvantages.

An object of the present invention is to provide a nesting apparatus capable of nesting by utilizing the advantages of the adjacent side commoning form and the spacing providing form, reducing the defects, improving the yield, shortening the processing time, and obtaining the processing stability. It is to be.
Another object of the present invention is to enable excellent nesting due to processing stability.
Still another object of the present invention is to make the crushing process as small as possible.
Still another object of the present invention is to limit the planar shape of the material plate after the component plate is carried out to an L shape, further improving the stability of processing and facilitating reuse of the end material. It is to plan.

The structure of this invention is demonstrated with FIG. 1 corresponding to embodiment. The first nesting device sets a part figure (M), which is a figure in which a tool used for punching is arranged around a part board cut out from a material board by punching, to the figure (W) of the material board A nesting device for arranging a plurality of arrangements according to the arrangement rule (R), wherein the set arrangement rule (R) is defined as follows.
That is, the set arrangement rule (R) is set to the side indicating the outer periphery of the tool display portion (Mt) in one part graphic (M) for the adjacent side (c) of the part graphic (M) arranged adjacent to each other. , Between the adjacent side common rule (Ra) and the adjacent part graphic (M) arranged to overlap the sides indicating the outer periphery of the component plate material display part (Mp) in the other part graphic (M) The adjacent side commonality is used when three or more component figures (M) are arranged with respect to the arrangement rule (Rb) for giving an interval to the figure and the figure (W) of one material plate material. It is assumed that there is a combination rule (Rc) that distinguishes and uses the arrangement using the rule (Ra) and the arrangement using the spacing assignment rule (Rb) according to the setting distinction criteria.

  According to the nesting device of this configuration, the adjacent side common rule (Ra) and the spacing provision arrangement rule (Rb) are used together, and the common side rule (Ra) and the spacing provision arrangement rule are determined by the combination rule (Rc). Since (Rb) is used separately, it is possible to make use of the advantages of each machining mode and reduce the influence of the defects of each machining mode. In other words, taking advantage of the improved yield by the adjacent side common mode and the processing time reduction and processing stability by the spacing arrangement mode, it is excellent in all of yield improvement, processing time reduction, and processing stability. Can be processed.

In this invention, the punching process is a process of feeding a raw material plate by holding a gripping side (Wa) that is one side of a rectangular raw material plate with a punch press machine, and as the setting arrangement rule (R), A part figure (M) arranged from one end of the free side (Wb), which is the side opposite to the grip side (Wa) of the figure (W) of the material plate material, to the other end along the free side (Wb). ), And in the remaining part of the figure (W) of the material plate material, there is an arrangement direction rule (Rda) arranged again from the one end to the other end side, and the combination rule (Rc) is a free side Arrangement of a row of part figures (M) along (Wb) is performed by the adjacent side sharing rule (Ra), and the remaining part includes a rule for arranging by the spacing assignment arrangement rule (Rb). There may be.
In the case of this configuration, the arrangement of the part figure (M) along the free side of the material plate material is performed by the adjacent side common rule (Ra), and the rest is arranged by the spacing arrangement rule (Rb). Done. Therefore, in the middle of processing, there is no cross-shaped part between the cut-out traces in the vicinity of the free side that is far from the holding side of the material plate, and each time a piece of component plate is cut out, the material plate is on the free side The area near the edge disappears and becomes smaller. Although a cross-shaped portion is generated in the vicinity of the fixed side, the vicinity of the free side of the material plate material is eliminated, so that the influence of catching due to the presence of the cross-shaped portion is small. For this reason, more stable processing can be performed.

In the case of this configuration, when the combined rule (Rc) further assumes that the part figures (M) are arranged in a line along the free side by the adjacent side commoning rule (Ra), A value (a) obtained by subtracting the total length in the direction along the free side of the arranged part figure (M) from the length (WX) of the free side of the figure (W) of the material plate material is less than the set value. In the case where the condition of the above is satisfied, the adjacent side sharing rule (Ra) may be adopted for the arrangement of the part figure (M) in a line of the free end.
Thus, as a condition for adopting the adjacent side sharing rule (Ra), by limiting to the case where the difference between the arrangement length of the component figure (M) and the length of the material plate material (WX) is less than the set value, The portion that needs to be crushed along with the adoption of the adjacent side sharing rule (Ra) becomes a limited area within the range of the set value. Therefore, the crushing process can be reduced as much as possible.

Further, according to the adjacent side sharing rule (Ra), the part figures (M) are arranged in a line along the free side, and the dimension of the part figure (M) having a long dimension in a direction orthogonal to the free side is When the maximum value (YMax) of the dimensional difference in the orthogonal direction between the arranged part figures (M) is assumed to be less than the set value when it is assumed that they are arranged in order from the one end side to the other end side. In addition, the combination rule (Rc) may be defined in such a manner that it is arranged according to the adjacent side sharing rule (Ra) and arranged with respect to the remaining portion according to the spacing assignment rule (Rb).
As a result, the planar shape of the material plate after the cut out component plate is carried out is limited to an L shape, further improving the stability of processing and facilitating reuse of the end material. Can do.

The second nesting device according to the present invention converts a part figure (M), which is a figure in which a tool used for punching is arranged, around a part board material cut out from a material board material by punching, into a figure (W) of the material board material. On the other hand, a nesting apparatus that arranges a plurality according to the set arrangement rule (R) is characterized in that the set arrangement rule (R) is defined as follows.
That is, as the setting arrangement rule (R), the side indicating the outer periphery of the tool display part (Mt) of the part figure (M) or the part board display part (Mp) where no tool is placed is used as the figure (W) of the material board material. Adjacent side common rule (Ra) that is arranged to overlap the side of the part, and an arrangement form that opens a gap between the tool display unit (Mt) of the part figure (M) and the side of the figure (W) of the material plate material The above-mentioned adjacent side sharing rule (Ra) is used for arranging two or more component figures (M) for a figure (W) with a spacing given by (Rb) and a figure (W) of one material plate material. It has a combination rule (Rc) for distinguishing and using the arrangement and the arrangement using the spacing assignment arrangement rule (Rb) according to the setting distinction criteria.

  Also in this configuration, it is possible to make use of the advantages of each processing form and reduce the influence of the defects of each processing form. In other words, taking advantage of the improved yield by the adjacent side common mode and the processing time reduction and processing stability by the spacing arrangement mode, it is excellent in all of yield improvement, processing time reduction, and processing stability. Can be processed.

  According to a first nesting device of the present invention, a component graphic, which is a graphic in which a tool used for punching is arranged around a component plate material cut out from a raw material plate material by punching, is set according to a set arrangement rule for the graphic of the material plate material. A plurality of nesting devices, wherein, as the setting arrangement rule, a component plate material in the other component graphic is arranged on the side indicating the outer periphery of the tool display portion in one component graphic for adjacent sides of the component graphic arranged adjacent to each other Adjacent side sharing rule that arranges the sides indicating the outer periphery of the sheet, an interval arrangement rule that arranges an interval between adjacent component figures, and a figure of one material board On the other hand, when three or more component figures are arranged, the arrangement using the adjacent side common rule and the arrangement using the spacing arrangement rule are set according to a setting distinction criterion. Because it has a combination rule used in combination distinguish, it is possible to obtain take advantage of the adjacent side common form and spacing imparting form, with less disadvantages, improving the yield, the processing time reduction, the stability of processing.

  The punching is a process of feeding a material plate by holding a holding side that is one side of a rectangular material plate with a punch press, and as the setting arrangement rule, the holding side of the figure of the material plate Arrange the part figure from one end of the free side, which is the opposite side, to the other side along the free side, and arrange again from the one end to the other side on the rest of the figure on the material board The combination rule is a rule in which the arrangement of part figures along a free side is arranged by the adjacent side common rule, and the remaining part is arranged by the spacing arrangement rule. When it contains, it is more excellent in processing stability.

  As the combined rule, when it is assumed that the component figures are arranged in a line along the free side by the adjacent side common rule, the total length in the direction along the free side of the arranged part figure Adjacent side rule is adopted for the arrangement of part figures in a row on the free end when the condition that the value obtained by subtracting from the length of the free side of the figure of the material board material is less than the set value is satisfied. When it is limited to do so, crushing can be reduced as much as possible.

  According to the adjacent side sharing rule, component figures are arranged in a row along the free side, and arranged in order from one end side to the other end in the order of part figures having a long dimension in a direction perpendicular to the free side. Assuming that the maximum value of the dimension difference in the orthogonal direction between the arranged part figures is less than the set value, it is arranged by the adjacent side common rule, and the remaining part When the combination rule is defined in the content of the spacing provision arrangement rule, the planar shape of the material plate after the component plate is carried out is restricted to be L-shaped, and the stability of processing is further improved. And it is possible to facilitate the reuse of the mill ends.

The punch press machine 21 includes a punching mechanism 23 that punches a material plate WR on a table 22 at a processing position P, and the material plate WR on the table 22 in the front-rear direction (Y-axis direction) and the left-right (X-axis direction). A plate material feed mechanism 24 to be moved to the frame 25 is installed on the frame 25. The plate material feeding mechanism 24 is configured such that a cross slide 27 is mounted on a carriage 26 that can be moved back and forth, and a plurality of work holders 28 that hold one side of the material plate material WR are attached to the cross slide 27. The punching mechanism 23 is a mechanism for drilling a material plate material WR using a tool composed of a punch die and a die die that are vertically opposed to each other. A punch drive mechanism (not shown) for moving up and down, and a tool indexing mechanism (not shown) such as a turret type capable of indexing an arbitrary tool to the processing position P by mounting a plurality of types of tools having different drilling shapes. Z). The punch press machine 21 is controlled by a control device 29 including a computer-type numerical control device.

  FIG. 1 shows a conceptual configuration of an automatic programming device 1 that generates NC data 30 that is a machining program to be executed by the control device 29 of FIG. This automatic programming device 1 is composed of a computer such as a personal computer and software such as programs and data to be executed by the computer. The hardware and software of these computers are used to execute the following tool placement means 2, nesting means 3, and execution. NC data converting means 4, tool-arranged part graphic storage means 5, and nesting result storage means 6 are configured.

  The tool placement means 2 is a means for determining the type and placement of the tool used for punching the component plate material indicated by the part figure Mp ′ for the part figure Mp ′ where the tool is not placed. It is stored as a component graphic M in the completed component graphic storage means 5. The component graphic M includes a plate material display portion Mp indicating the shape of the component plate material, and a tool display portion Mt disposed around the plate material display portion Mp. The tool display portion Mt is a portion that displays the shape of a hole drilled by the tool at each drilling position with respect to the plate material display portion Mp. When punching is performed inside the component plate material, the tool display unit Mt also displays the inside of the plate material display unit Mp. The tool placement by the tool placement means 2 is performed using a stored tool master file (not shown) in which a tool number and a drilled shape are associated with each other.

Also good.

  The nesting means 3 is means for performing nesting, which is a process of arranging a plurality of the component figures M with respect to the figure W of the material plate material according to the set arrangement rule R. The nesting means 3 performs nesting for all the part figures M stored in the tool-arranged part figure storage means 5. Of the part figures M stored in the tool-arranged part figure storage means 5, nesting may be performed for the part figure M that is selected for nesting at the same time. When the part figure M to be nested does not fit in the figure W of one material plate material, nesting is performed on the figure W of a plurality of material plate materials. The setting arrangement rule R will be described later. The nesting result data ND of the nesting means 3 is stored in the nesting result data storage means 6.

  The NC data conversion means 4 is means for generating NC data 30 in an executable format by performing predetermined processing on the nesting result data ND.

  As the setting arrangement rule R of the nesting means 3, an adjacent side common rule Ra, a spacing assignment rule Rb, a combination rule Rc, and a common rule Rd are provided. The setting arrangement rule R in this embodiment is a process in which punching is performed by holding the holding side WRa which is one side of the rectangular material plate material WR by the work holder 28 of the punch press machine 21 and feeding the material plate material WR. It is provided on the assumption that.

The adjacent side sharing rule Ra is set such that, for each adjacent side of the part figure M arranged adjacent to the part figure M, the part plate material display part Mp in the other part figure M is arranged on the side indicating the outer periphery of the tool display part Mt. It is a rule which makes it the arrangement | positioning form which overlaps the side which shows the outer periphery. In the adjacent side sharing rule Ra of this embodiment, the side of the outer periphery of the material board material figure W is arranged to overlap the side indicating the outer periphery of the part board material display portion Mp in the part figure M. The adjacent side sharing rule Ra is an arrangement in which the side indicating the outer periphery of the tool display portion Mt is overlapped with the side of the figure W of the material plate material with respect to the outer side of the material plate material figure W. It is also good.
The interval giving arrangement rule Rb is a rule that forms an arrangement in which an interval equal to or larger than the set interval is provided between the component figures M arranged adjacent to each other. In the interval giving arrangement rule Rb of this embodiment, the arrangement form is set such that an interval equal to or larger than the set interval is also formed on the outer peripheral side of the material plate material figure W. For example, it is set as the rule made into the arrangement | positioning form which opens a space | interval between the tool display part Mt and the edge | side of the figure W of a raw material board | plate material.

  The common rule Rd is a rule that is commonly adopted by both the adjacent side common rule Ra and the spacing assignment rule Rb. Here, the arrangement direction rule Rda is set as the common rule Rd. The arrangement direction rule Rda is changed from one end (the end on the right end side in FIG. 1) of the free side Wb that is the side opposite to the gripping side Wa by the punch press 21 of the raw material board material W to the free side Wb. A part figure M is arranged side by side along the other end side, and is arranged again on the remaining part of the material board figure W from the one end to the other end side.

The combination rule Rc is an arrangement that uses the adjacent side common rule Ra and an arrangement that uses the spacing assignment arrangement rule Rb when arranging three or more part figures M with respect to a figure W of a single sheet material. Are used in accordance with the setting distinction criteria.
As the combined rule Rc, the following first condition, second condition, and third condition are provided here. When all of these conditions are satisfied, the adjacent side sharing rule Ra is used and the condition is not satisfied. Are those using the spacing arrangement rule Rb.

The first condition is that when it is assumed that the component figures M are arranged in a line along the free side Wb of the material board material figure W as shown in FIG. A value a obtained by subtracting the total length (PX1 + PX2 +... PXn) of M along the free side Wb (X direction) from the length WX of the free side Wb of the material board figure W is less than the set value (x1). It is a condition that
That is, the following formula: a = (material width XW) − (PX1 + PX2 +... PXn) <(set value X0)
Is to satisfy. “N” in PXn indicates the maximum number of lines.
The “set value X0” may be arbitrarily determined. For example, the “set value X0” is set to a dimension that allows overtaking processing in one direction (Y direction). That is, the X direction width of the tool having the maximum X direction width among the tools that are overtaken in the Y direction is set. The overtaking process is a process for forming a continuous hole by repeating punching with the same tool using a different punch position.

The second condition is that the component figure M is arranged in a line along the free side Wa and the dimension in the direction (Y direction) orthogonal to the free side Wa as shown in FIG. Are arranged in the order of the long part figure M from the one end side (the right side in the figure) to the other end side, the dimensions in the orthogonal direction (Y direction) between the arranged part figures M are as follows. This is a condition in which the maximum difference value (YMax) is less than the set value (Y0).
That is, YMax (maximum difference in Y size of arranged parts) <set value Y0
The “set value Y0” in this case may be arbitrarily determined. In addition, when arrange | positioning by the adjacent side common rule Ra, it arrange | positions from the said one end side (right side of a figure) to the other end side in order of the part figure M with a long dimension of the direction (Y direction) orthogonal to the free side edge Wa. .

  The third condition is a condition that the arrangement of the part figures M along the free side Wb is performed by the adjacent side sharing rule Ra, and the remaining part is performed by the spacing arrangement rule Rb. The third condition can be said to be a limitation when the adjacent side sharing rule Ra is adopted, rather than a condition of whether or not the adjacent side sharing rule Ra is adopted.

In addition, when any one of the first to third or any two conditions are satisfied, the adjacent side sharing rule Ra may be adopted. For example, regardless of whether the first condition and the second condition are satisfied, the adjacent side sharing rule Ra and the spacing assignment rule Rb are always used together, but the third condition may be observed.
Further, when either the first condition or the second condition is satisfied, the adjacent side sharing rule Ra and the spacing assignment rule Rb are used together, but the third condition may be observed.
Further, when either the first condition or the second condition is satisfied, the adjacent side sharing rule Ra and the spacing assignment rule Rb are used together, but the third condition may not be observed.
For these first to third conditions, for example, a selection means (not shown) for selecting a combination of arbitrary conditions by an input of selection and determination by the operator from the input means may be provided.

A specific example of nesting by the above configuration will be described. FIG. 4 shows a component figure M of each component plate material that is nested at the same time. The nesting result is shown in FIG. This specific example shows a case where all of the first to third conditions are satisfied and the adjacent side sharing rule Ra and the spacing provision rule Rb are used in combination.
That is, the arrangement of the part figures M along the free side Wb is performed by the adjacent side sharing rule Ra, and the remaining part is performed by the spacing arrangement rule Rb.
Also, (material width XW) − (PX1 + PX2) = a = 0
The first condition is satisfied regardless of the value of the set value X0.
Regarding the second condition, the setting value Y0 has not been described above, but here, it is assumed that the setting value Y0 is set to a value equal to or greater than YMax.

  In addition, regarding the tool arrangement for the part graphic M, when the arrangement is performed with the adjacent side common rule Ra, it is not necessary to arrange the tools on the sides to be shared in the part graphic M (the right side and the upper side in the figure). Suppose that every part figure M has a tool placement part Mt on the entire circumference, and when placing with the adjacent side common rule Ra, the tool placement part Mt is omitted for the common side, or the tool placement part Mt. Is overlapped with the adjacent component figure M. The adjacent side sharing rule Ra is determined so that no tools are arranged in the nesting result data ND for the omitted or stacked tools. Alternatively, for each part figure M, as shown in FIG. 4A, there are two kinds of parts figure M having a tool placement part Mt on the entire circumference and a part figure without the tool placement part Mt for the common side. It is good also as what prepares and employ | adopts the part figure M from which the tool arrangement | positioning part Mt was excluded about the common side by the adjacent side common rule Ra.

  According to the nesting device of this configuration, as described above, the adjacent side common rule Ra and the spacing assignment rule Rb are used together, and the adjacent side common rule Ra and the spacing assignment rule Rb are determined by the combination rule Rc. Since they are used in distinction, it is possible to make use of the advantages of each processing form and reduce the influence of the determinations of each processing form. In other words, taking advantage of the yield improvement by the adjacent side common mode Ra and the processing time reduction and the processing stability by the spacing arrangement configuration Rb, any of the improvement of the yield, the processing time, and the processing stability Can also perform excellent processing.

  In the case where the arrangement of the part figures M along the free side Wb of the raw material plate material is performed by the adjacent side common rule Ra and the arrangement is performed by the spacing assignment rule Rb in the remaining part, In the vicinity of the free side Wb far from the gripping side edge Wa of the material plate material, there is no cross-shaped portion between the cutout traces, and each time one component plate material MR is cut out, the material plate material WR The neighborhood disappears and becomes smaller. Although a cross-shaped portion is generated in the vicinity of the fixed side WRa, since the vicinity of the free side WRb of the raw material plate material WR is lost, the influence of catching and the like due to the presence of the cross-shaped portion is small. For this reason, more stable processing can be performed.

  As a condition for adopting the adjacent side sharing rule Ra, when the difference a between the arrangement length (PX1 + PX2 +... PXn) of the component figure M and the length XW of the material plate material is less than the set value X0, The portion that needs to be crushed along with the adoption of the common rule Ra has a limited area within the width of the set value X0. Therefore, the crushing process can be reduced as much as possible. In particular, when the set value X0 is set to a value that can be obtained by overtaking in one direction, the crushing can be performed by one overtaking, and the crushing can be easily performed.

  Further, as described above, the adjacent side sharing rule is limited to the case where the maximum value YMax of the dimension difference in the orthogonal direction (Y direction) between the arranged part figures M is less than the set value Y0. When arranged in Ra, the planar shape of the material plate material WR after the cut out component plate material MR is restricted to be L-shaped, which further improves the processing stability and the end material. Can be easily reused.

  In the above-described embodiment, the adjoining side rule Ra, the spacing assignment rule Rb, and the combination rule Rc in the setting arrangement rule R may have the following contents. That is, the adjoining side generalization rule Ra has an arrangement form in which the side indicating the outer periphery of the tool display part Mt or the part board material display part Mp of the part figure M is overlapped with the side of the figure W of the material board material, In addition, it is assumed that the spacing provision arrangement rule Rb is a rule that forms a spacing between the tool display portion Mt of the part figure M and the side of the figure W of the material plate material. In this case, the combined use rule Rc includes the arrangement using the adjacent side sharing rule Ra and the spacing assignment arrangement rule for arranging two or more component figures M on the figure W of one material plate material. The arrangement using (Rb) is a rule for distinguishing and using together according to the setting distinction criteria.

  Two types of arrangement result examples in the case where the setting arrangement rule R is described are shown in FIGS. 6 (A) and 6 (B), respectively. FIG. 6A is an example in which the side indicating the outer periphery of the component board material display portion Mp of the part graphic M is arranged to overlap the side of the figure W of the material board material. FIG. 6B is an example in which the side indicating the outer periphery of the tool display portion Mt of the part graphic M is arranged to overlap the side of the graphic W of the material plate material.

The nesting device according to claim 1, comprising:   The combined rule is the total length in the direction along the free side of the arranged part graphic, assuming that the part graphic is arranged in a line along the free side by the adjacent side common rule. Adjacent side rule is adopted for the arrangement of part figures in a row on the free end when the condition that the value obtained by subtracting from the length of the free side of the figure of the material board material is less than the set value is satisfied. The nesting device according to claim 2.   According to the adjacent side sharing rule, component figures are arranged in a row along the free side, and arranged in order from one end side to the other end in the order of part figures having a long dimension in a direction perpendicular to the free side. Assuming that the maximum value of the dimension difference in the orthogonal direction between the arranged part figures is less than the set value, it is arranged by the adjacent side common rule, and the remaining part The nesting device according to claim 2 or 3, wherein the combination rule is defined in the content of the interval assignment arrangement rule. A nesting device that arranges a plurality of component figures, which are figures in which a tool used for punching is arranged, in accordance with a set arrangement rule with respect to a figure of a material board material, around a component board material to be cut by punching from a material board material,
As the setting arrangement rule, the adjacent side commonization rule in which the side indicating the outer periphery of the part board material display part on which the tool graphic part of the part graphic or the tool is not arranged is overlapped with the side of the material board figure, and the part Interval arrangement rules with an arrangement form in which a space is provided between the figure tool display section and the side of the material board figure, and two or more part figures are arranged on one piece of material board figure A nesting device comprising: a combination rule that distinguishes and uses an arrangement that uses the adjacent side sharing rule and an arrangement that uses the spacing assignment rule according to a setting distinction criterion.
