Abstract

[Problem] To subject, to batch processing, nesting for arranging a specific product, in which a hole is to be formed by drilling, at a position at which the position of a protruding part and a region where the hole is to be formed do not overlap. [Solution] A program generation device comprising a nesting unit that carries out nesting for arranging a figure representing a product expressed by a closed figure. The program generation device comprises a program generation unit that generates a program including data related to the arrangement of a figure representing a product nested by the nesting unit. As concerns a specific product in which a hole is to be formed by drilling for irradiating a laser beam along a prescribed closed path, the nesting unit can determine whether the position of a protruding part of a pallet that supports a workpiece and the region where the hole is to be formed are overlapping. If the position of the protruding part and the region where the hole is to be formed are overlapping, the nesting unit rearranges the figure representing the specific product to a position at which the position of the protruding part and the region where the hole is to be formed do not overlap.

　レーザ加工は、パレットに設けられた複数の突起部により板状のワークを支持した状態で行われるが、パレットに設けられた複数の突起部の位置を考慮しない場合、不具合が生じる可能性がある。そこで、プログラム装置は、ネスティングにおいて、パレットに設けられた複数の突起部の位置を考慮して、製品を示す図形を配置することがある（例えば、特許文献１参照）。 Laser processing is performed with a plate-shaped workpiece supported by multiple protrusions provided on the pallet, but if the positions of the multiple protrusions provided on the pallet are not taken into consideration, problems may occur. . Therefore, in nesting, a programming device may arrange a figure representing a product in consideration of the positions of a plurality of protrusions provided on a pallet (see, for example, Patent Document 1).

　ところで、レーザ加工機は、穴あけ加工と呼ばれる加工により、所定の閉経路に沿ってレーザ光を照射して穴部を形成できる。穴あけ加工によりワークから切断されるスラグは、通常、ワークから落下して除去される。しかし、パレットの突起部と重なる位置に穴部が形成されている場合、スラグは、突起部によって落下が阻害され、穴部に嵌まり込んで落下しない可能性がある。 By the way, a laser processing machine can form a hole by irradiating a laser beam along a predetermined closed path through a process called drilling. Slag cut from a workpiece by drilling usually falls from the workpiece and is removed. However, if a hole is formed in a position that overlaps with a protrusion of the pallet, the slag may be prevented from falling by the protrusion, and may fit into the hole and not fall.
　この問題は、例えば、ネスティングされた製品を示す図形の配置を作業者が目視確認し、突起部の位置と、穴部となる領域とが重なっている場合、その製品を示す図形を作業者が移動させることにより回避できる。しかし、この方法は、バッチ処理によるネスティングを中断しなければならず、適当でない。 For example, if a worker visually checks the placement of a shape that represents a nested product and the position of a protrusion overlaps with the area that will become a hole, the worker visually checks the layout of the shape that represents the product. This can be avoided by moving. However, this method requires interruption of nesting by batch processing and is not suitable.

Here, the nesting process by the nesting unit 132 will be described with the starting state being a state in which design data is received by the design data receiving unit 131 and the design data is stored in the data storage unit 135.
　データ記憶部１３５に設計データが記憶されると、ネスティング部１３２は、データ記憶部１３５に格納されている設計データを読み出す（Ｓ１０１）。 When the design data is stored in the data storage unit 135, the nesting unit 132 reads the design data stored in the data storage unit 135 (S101).
　次に、ネスティング部１３２は、ワークＷを示す図形の中に、製品Ｐを示す図形を初期位置に配置する（Ｓ１０２）。ここで、設計データは、二次元の閉図形によって表現されるワークＷを示す図形の中に、二次元の閉図形によって表現される製品Ｐを示す図形を配置する初期位置に関する情報を含む。ネスティング部１３２は、この情報に基づいて、二次元の閉図形によって表現されるワークＷを示す図形の中に、二次元の閉図形によって表現される製品Ｐを示す図形を配置する。 Next, the nesting unit 132 places a figure representing the product P in the initial position among the figures representing the workpiece W (S102). Here, the design data includes information regarding an initial position at which a figure representing the product P represented by a two-dimensional closed figure is placed in a figure representing the workpiece W represented by a two-dimensional closed figure. Based on this information, the nesting unit 132 arranges a figure representing the product P represented by a two-dimensional closed figure in a figure representing the workpiece W represented by a two-dimensional closed figure.
　図４は、ワークＷを示す図形の中に配置された製品Ｐを示す図形の初期位置の一例を概略的に示す。この例では、ワークＷを示す図形の中に、製品Ｐ１を示す図形と、製品Ｐ２を示す図形と、製品Ｐ３を示す図形と、製品Ｐ４を示す図形とが初期位置に配置されている。例えば、製品Ｐ１を示す図形は、Ｙ方向において、製品Ｐ２を示す図形から離れて配置されている。また、製品Ｐ１を示す図形は、Ｘ方向において、製品Ｐ３を示す図形から離れて配置されている。 FIG. 4 schematically shows an example of the initial position of a figure indicating a product P placed within a figure indicating a workpiece W. In this example, among the figures indicating the workpiece W, a figure indicating the product P1, a figure indicating the product P2, a figure indicating the product P3, and a figure indicating the product P4 are arranged at initial positions. For example, a graphic representing product P1 is placed apart from a graphic representing product P2 in the Y direction. Furthermore, the figure representing the product P1 is placed apart from the figure representing the product P3 in the X direction.
　次に、ネスティング部１３２は、穴部Ｈが形成される特定の製品Ｐがあるかを判定する（Ｓ１０３）。例えば、設計データは、製品Ｐを示す図形に対応付けて、穴あけ加工により穴部Ｈが形成される特定の製品Ｐであるかを示す特定の情報が付されていてもよい。その場合、ネスティング部１３２は、特定の情報が付されているときに、穴あけ加工により穴部Ｈが形成される特定の製品Ｐがあると判定する。また、例えば、ネスティング部１３２は、製品Ｐを示す図形の中に、二次元の閉図形によって表現される図形があるときに、穴あけ加工により穴部Ｈが形成される特定の製品Ｐがあると判定する。図４に示す例の場合、製品Ｐ１は、穴部Ｈ１～穴部Ｈ８が形成される特定の製品Ｐである。したがって、この例の場合、ネスティング部１３２は、穴あけ加工により穴部Ｈが形成される特定の製品Ｐがあると判定する。 Next, the nesting unit 132 determines whether there is a specific product P in which the hole H is formed (S103). For example, the design data may be associated with a figure representing the product P and include specific information indicating whether the product P is a specific product P in which a hole H is formed by drilling. In that case, the nesting unit 132 determines that there is a specific product P in which a hole H is formed by drilling when specific information is attached. Further, for example, when there is a figure expressed by a two-dimensional closed figure among the figures representing the product P, the nesting unit 132 may detect that there is a specific product P in which a hole H is formed by drilling. judge. In the example shown in FIG. 4, the product P1 is a specific product P in which the holes H1 to H8 are formed. Therefore, in this example, the nesting unit 132 determines that there is a specific product P in which a hole H is formed by drilling.
　Ｓ１０３において特定の製品Ｐがない場合（Ｓ１０３；ＮＯ）、ネスティング部１３２は、図３に示す処理を終了する。 If there is no specific product P in S103 (S103; NO), the nesting unit 132 ends the process shown in FIG. 3.
　Ｓ１０３において特定の製品Ｐがある場合（Ｓ１０３；ＹＥＳ）、ネスティング部１３２は、特定の製品Ｐの数をカウントするためのカウンタ“Ｌ”に、特定の製品Ｐの数を設定する（Ｓ１０４）。 If there is a specific product P in S103 (S103; YES), the nesting unit 132 sets the number of specific products P to the counter "L" for counting the number of specific products P (S104).
　次に、ネスティング部１３２は、Ｌ番目の特定の製品Ｐに形成される穴部Ｈとなる領域と、パレット１１１における突起部Ｔの位置とが重なっているかを判定する（Ｓ１０５）。Ｓ１０５において、ネスティング部１３２は、穴部Ｈをとなる領域について、ＸＹ平面における座標を算出する。例えば、穴部Ｈの形状が真円である場合、ネスティング部１３２は、穴部Ｈの中心の座標と、穴部Ｈの半径の長さとに基づいて、穴部Ｈとなる領域について、ＸＹ平面における座標を算出する。また、ネスティング部１３２は、データ記憶部１３５に記憶されているＸＹ平面における突起部Ｔの座標を示すデータを読み出す。そして、ネスティング部１３２は、ＸＹ平面における穴部Ｈとなる領域の中に突起部Ｔの座標が位置するかを判定する。穴部Ｈとなる領域の中に突起部Ｔの座標が位置するとき、ネスティング部１３２は、Ｌ番目の特定の製品Ｐに形成される穴部Ｈとなる領域と、パレット１１１における突起部Ｔの位置とが重なっていると判定する。図４に示す例では、穴部Ｈ３となる領域の中に突起部Ｔの座標が位置している。したがって、ネスティング部１３２は、特定の製品Ｐ１に形成される穴部Ｈとなる領域と、パレット１１１における突起部Ｔの位置とが重なっていると判定する。 Next, the nesting unit 132 determines whether the area that will become the hole H formed in the L-th specific product P and the position of the protrusion T on the pallet 111 overlap (S105). In S105, the nesting unit 132 calculates coordinates in the XY plane for the area where the hole H is located. For example, when the shape of the hole H is a perfect circle, the nesting unit 132 determines the area that will become the hole H on the XY plane based on the coordinates of the center of the hole H and the length of the radius of the hole H. Calculate the coordinates at . Further, the nesting unit 132 reads data indicating the coordinates of the protrusion T in the XY plane, which is stored in the data storage unit 135. Then, the nesting unit 132 determines whether the coordinates of the protrusion T are located within the region that will become the hole H on the XY plane. When the coordinates of the protrusion T are located in the area that will become the hole H, the nesting part 132 will be located between the area that will become the hole H formed in the L-th specific product P and the area of the protrusion T on the pallet 111. It is determined that the positions overlap. In the example shown in FIG. 4, the coordinates of the protrusion T are located within the area that will become the hole H3. Therefore, the nesting unit 132 determines that the area that will become the hole H formed in the specific product P1 and the position of the protrusion T on the pallet 111 overlap.
　Ｓ１０５において穴部Ｈとなる領域と、突起部Ｔの位置とが重なっている場合（Ｓ１０５；ＹＥＳ）、ネスティング部１３２は、Ｌ番目の特定の製品Ｐを示す図形を一定距離移動させる（Ｓ１０６）。特定の製品Ｐを移動させる方向は、Ｘ方向、Ｙ方向、Ｘ方向とＹ方向とを合成した方向のいずれの方向であってもよい。 If the area that will become the hole H and the position of the protrusion T overlap in S105 (S105; YES), the nesting unit 132 moves the figure representing the L-th specific product P by a certain distance (S106). . The direction in which the specific product P is moved may be any of the X direction, the Y direction, and the combination of the X and Y directions.
　図５は、特定の製品Ｐを示す図形を所定方向に一定距離移動させる方法の一例を概略的に示す。この例では、特定の製品Ｐ１を示す図形を＋Ｘ方向に一定距離移動させている。 FIG. 5 schematically shows an example of a method for moving a figure representing a specific product P a certain distance in a predetermined direction. In this example, a figure indicating a specific product P1 is moved a certain distance in the +X direction.
　次に、ネスティング部１３２は、Ｌ番目の特定の製品Ｐと他の製品Ｐとが重なっているかを判定する（Ｓ１０７）。Ｓ１０７において、ネスティング部１３２は、例えば、Ｌ番目の製品Ｐを示す図形と、他の製品Ｐを示す図形とが交差するとき、ネスティング部１３２は、Ｌ番目の特定の製品Ｐと他の製品Ｐとが重なっていると判定する。 Next, the nesting unit 132 determines whether the L-th specific product P and other products P overlap (S107). In S107, the nesting unit 132, for example, when a figure indicating the L-th product P and a figure indicating another product P intersect, the nesting unit 132 intersects the L-th specific product P and the other product P. It is determined that the two overlap.
　図６は、特定の製品Ｐと他の製品Ｐとが重なっている状態の一例を概略的に示す。この例では、特定の製品Ｐ１を示す図形と、他の製品Ｐ２を示す図形とが交差しており、特定の製品Ｐ１と他の製品Ｐ２とが重なっている。 FIG. 6 schematically shows an example of a state in which a specific product P and another product P overlap. In this example, a graphic indicating a specific product P1 and a graphic indicating another product P2 intersect, and the specific product P1 and the other product P2 overlap.
　Ｓ１０７において他の製品Ｐと重なっている場合（Ｓ１０７；ＹＥＳ）、ネスティング部１３２は、Ｌ番目の特定の製品Ｐを示す図形を、重なっている他の製品Ｐを示す図形から離れる方向に一定距離移動させる（Ｓ１０８）。特定の製品Ｐを移動させる方向は、Ｘ方向、Ｙ方向、Ｘ方向とＹ方向とを合成した方向のいずれの方向であってもよい。 If the product P overlaps with another product P in S107 (S107; YES), the nesting unit 132 moves the shape representing the Lth specific product P by a certain distance in the direction away from the shape representing the other overlapping product P. It is moved (S108). The direction in which the specific product P is moved may be any of the X direction, the Y direction, and the combination of the X and Y directions.
　図７は、特定の製品Ｐを示す図形を他の製品Ｐを示す図形から離れる方向に一定距離移動させる方法の一例を概略的に示す。この例では、特定の製品Ｐ１を示す図形を、他の製品Ｐ２を示す図形から離れる方向となる＋Ｘ方向と－Ｙ方向とを合成した方向に一定距離移動させている。 FIG. 7 schematically shows an example of a method for moving a figure representing a specific product P a certain distance in a direction away from figures representing other products P. In this example, a graphic representing a specific product P1 is moved a certain distance in a direction that is a combination of the +X direction and the -Y direction, which is a direction away from the graphic representing another product P2.
　Ｓ１０８の処理を実行した後、ネスティング部１３２は、再びＳ１０７の処理を実行する。ネスティング部１３２は、Ｓ１０７において他の製品Ｐと重ならなくなるまで、Ｓ１０７、Ｓ１０８の処理を繰り返し実行する。 After executing the process in S108, the nesting unit 132 executes the process in S107 again. The nesting unit 132 repeatedly executes the processes of S107 and S108 until the product P no longer overlaps with other products P in S107.
　Ｓ１０７において特定の製品Ｐと他の製品Ｐとが重なっていない場合（Ｓ１０７；ＮＯ）、ネスティング部１３２は、再びＳ１０５の処理を実行する。ネスティング部１３２は、Ｓ１０５において穴部Ｈとなる領域と、突起部Ｔの位置とが重ならなくなるまで、Ｓ１０５～Ｓ１０８の処理を繰り返し実行する。 If the specific product P and other products P do not overlap in S107 (S107; NO), the nesting unit 132 executes the process in S105 again. The nesting unit 132 repeatedly executes the processes of S105 to S108 until the area that will become the hole H and the position of the protrusion T no longer overlap in S105.
　図８は、特定の製品Ｐの穴部Ｈとなる領域と、突起部Ｔの位置とが重なっていない状態の一例を概略的に示す。この例では、特定の製品Ｐ１に形成される穴部Ｈとなるいずれの領域も、パレット１１１における突起部Ｔの位置と重なっていない。 FIG. 8 schematically shows an example of a state where the area that will become the hole H of a specific product P and the position of the protrusion T do not overlap. In this example, none of the areas forming the holes H formed in the specific product P1 overlap with the positions of the protrusions T on the pallet 111.
　Ｓ１０５において穴部Ｈとなる領域と、突起部Ｔの位置とが重なっていない場合、ネスティング部１３２は、カウンタ“Ｌ”の値を“１”減算する（Ｓ１０９）。 If the area that will become the hole H and the position of the protrusion T do not overlap in S105, the nesting unit 132 subtracts "1" from the value of the counter "L" (S109).
　そして、ネスティング部１３２は、カウンタ“Ｌ”の値が“０”であるかを判定する（Ｓ１１０）。カウンタ“Ｌ”の値が“０”であることは、穴部Ｈが形成される全ての特定の製品Ｐについて、穴部Ｈとなる領域と、突起部Ｔの位置とが重ならない位置となるようにネスティングされたことを意味する。 Then, the nesting unit 132 determines whether the value of the counter "L" is "0" (S110). The value of the counter "L" being "0" means that for all specific products P in which the hole H is formed, the area that will become the hole H and the position of the protrusion T do not overlap. This means that they are nested.
　Ｓ１１０においてカウンタ“Ｌ”の値が“０”でない場合（Ｓ１１０；ＮＯ）、ネスティング部１３２は、再びＳ１０５の処理を実行する。ネスティング部１３２は、Ｓ１１０においてカウンタ“Ｌ”の値が“０”となるまで、Ｓ１０５～Ｓ１１０の処理を繰り返し実行する。 If the value of the counter "L" is not "0" in S110 (S110; NO), the nesting unit 132 executes the process of S105 again. The nesting unit 132 repeatedly executes the processes of S105 to S110 until the value of the counter "L" becomes "0" in S110.
　Ｓ１１０においてカウンタ“Ｌ”の値が“０”である場合（Ｓ１１０；ＹＥＳ）、ネスティング部１３２は、図３に示す処理を終了する。 If the value of the counter "L" is "0" in S110 (S110; YES), the nesting unit 132 ends the process shown in FIG. 3.
　ネスティング部１３２は、図３に示す処理を終了すると、ネスティングされた製品Ｐを示す図形の配置に関するデータを、データ記憶部１３５に記憶させる。 When the nesting unit 132 completes the process shown in FIG. 3, the nesting unit 132 causes the data storage unit 135 to store data regarding the arrangement of the figures representing the nested products P.
　プログラム生成部１３３は、ネスティング部１３２によりネスティングされた製品Ｐを示す図形の配置に関するデータを含むプログラムを生成する。プログラム送信部１３４は、プログラム生成部１３３により生成されたプログラムを、数値制御装置１４０へ送信する。数値制御装置１４０は、プログラム生成装置１３０からプログラムを受信すると、そのプログラムを解析して、レーザ加工機１１０を制御する。 The program generation unit 133 generates a program that includes data regarding the arrangement of figures representing the products P nested by the nesting unit 132. The program transmitter 134 transmits the program generated by the program generator 133 to the numerical control device 140. Upon receiving the program from the program generation device 130, the numerical control device 140 analyzes the program and controls the laser processing machine 110.
　以上、上記実施形態におけるプログラム生成装置１３０は、設計データに基づいて、レーザ加工に必要な各種情報を含むプログラムを生成する。プログラム生成装置１３０は、二次元の閉図形によって表現されるワークＷを示す図形の中に、二次元の閉図形によって表現される製品Ｐを示す図形を配置するネスティングを行うネスティング部１３２を備える。また、プログラム生成装置１３０は、ネスティング部１３２によりネスティングされた製品Ｐを示す図形の配置に関するデータを含むプログラムを生成するプログラム生成部１３３を備える。ネスティング部１３２は、所定の閉経路に沿ってレーザ光を照射する穴あけ加工により穴部Ｈが形成される特定の製品Ｐについて、ワークＷを支持するパレット１１１における突起部Ｔの位置と、穴部Ｈとなる領域とが重なっているかを判定可能である。ネスティング部１３２は、突起部Ｔの位置と、穴部Ｈとなる領域とが重なっている場合に、突起部Ｔの位置と、穴部Ｈとなる領域とが重ならない位置に、特定の製品Ｐを示す図形を再配置する。 As described above, the program generation device 130 in the above embodiment generates a program including various information necessary for laser processing based on design data. The program generation device 130 includes a nesting unit 132 that performs nesting in which a figure representing a product P represented by a two-dimensional closed figure is placed in a figure representing a workpiece W represented by a two-dimensional closed figure. The program generation device 130 also includes a program generation unit 133 that generates a program including data regarding the arrangement of figures representing the product P nested by the nesting unit 132. The nesting unit 132 determines the position of the protrusion T on the pallet 111 that supports the workpiece W and the hole part for a specific product P in which a hole H is formed by drilling by irradiating a laser beam along a predetermined closed path. It is possible to determine whether the area corresponding to H overlaps.

　ネスティング部１３２は、特定の製品Ｐを示す図形を再配置するにあたり、特定の製品Ｐを示す図形を一定距離ずつ移動させる。そして、ネスティング部１３２は、特定の製品Ｐを示す図形を一定距離移動させる度に、突起部Ｔの位置と、穴部Ｈとなる領域とが重なっているかを判定する。 When the nesting unit 132 rearranges the graphic representing the specific product P, the nesting unit 132 moves the graphic representing the specific product P by a fixed distance. Then, the nesting unit 132 determines whether the position of the protrusion T and the area that will become the hole H overlap each time the figure representing the specific product P is moved a certain distance.
　この実施形態によれば、突起部Ｔの位置と、穴部Ｈとなる領域とが重ならない位置に、特定の製品Ｐを示す図形を効率よく再配置できる。 According to this embodiment, the figure representing the specific product P can be efficiently rearranged to a position where the position of the protrusion T and the area that will become the hole H do not overlap.
　ネスティング部１３２は、特定の製品Ｐを示す図形を移動させた後に、特定の製品Ｐと他の製品Ｐとが重なっているかを判定可能である。そして、ネスティング部１３２は、特定の製品Ｐと他の製品Ｐとが重なっている場合に、特定の製品Ｐを示す図形を、重なっている他の製品Ｐを示す図形から離れる方向に移動させる。 The nesting unit 132 can determine whether the specific product P and another product P overlap after moving the graphic representing the specific product P. Then, when a specific product P and another product P overlap, the nesting unit 132 moves the graphic representing the specific product P in a direction away from the overlapping graphic representing the other product P.

　Ｓ１０７において他の製品Ｐと重なっている場合（Ｓ１０７；ＹＥＳ）、ネスティング部１３２は、Ｌ番目の特定の製品Ｐを示す図形を、重なる直前の位置に戻す（Ｓ２０８Ａ）。そして、ネスティング部１３２は、Ｌ番目の特定の製品Ｐを示す図形を、重なる直前に移動させた方向と異なる方向に移動させる（Ｓ２０８Ｂ）。 If it overlaps with another product P in S107 (S107; YES), the nesting unit 132 returns the figure indicating the L-th specific product P to the position immediately before the overlap (S208A). Then, the nesting unit 132 moves the figure representing the L-th specific product P in a direction different from the direction in which it was moved immediately before it overlapped (S208B).
　Ｓ２０８Ｂの処理を実行した後、ネスティング部１３２は、再びＳ１０７の処理を実行する。ネスティング部１３２は、Ｓ１０７において他の製品Ｐと重ならなくなるまで、Ｓ１０７、Ｓ２０８Ａ、Ｓ２０８Ｂの処理を繰り返し実行する。 After executing the process of S208B, the nesting unit 132 executes the process of S107 again. The nesting unit 132 repeatedly executes the processes of S107, S208A, and S208B until the product P no longer overlaps with other products P in S107.
　以上、この変形例におけるネスティング部１３２は、特定の製品Ｐを示す図形を移動させた後に、特定の製品Ｐと他の製品Ｐとが重なっているかを判定可能である。そして、ネスティング部１３２は、特定の製品Ｐと他の製品Ｐとが重なっている場合に、特定の製品Ｐを示す図形を、重なる直前の位置に戻した後に、重なる直前に移動させた方向と異なる方向に移動させる。 As described above, the nesting unit 132 in this modification can determine whether the specific product P overlaps with another product P after moving the figure representing the specific product P. Then, when a specific product P and another product P overlap, the nesting unit 132 returns the figure representing the specific product P to the position immediately before the overlap, and then returns the figure to the direction in which it was moved immediately before the overlap. Move it in different directions.
　この変形例によれば、特定の製品Ｐを示す図形を移動させるときに、特定の製品Ｐを示す図形と他の製品Ｐを示す図形とが重なることを防止できる。 According to this modification, when moving a graphic representing a specific product P, it is possible to prevent the graphic representing the specific product P from overlapping with the graphic representing another product P.
　上記変形例において、ネスティング部１３２は、特定の製品Ｐと他の製品Ｐとが重なっている場合に、特定の製品Ｐを示す図形を、重なる直前の位置ではなく初期位置に戻した後に、異なる方向に移動させてよい。 In the above modification, when a specific product P and another product P overlap, the nesting unit 132 returns the figure indicating the specific product P to the initial position instead of the position immediately before the overlap, and then You can move it in the direction.
　上記実施形態及び上記変形例において、ネスティング部１３２は、突起部Ｔの位置と、穴部Ｈとなる領域とが重ならなくなるまで、特定の製品Ｐを示す図形を移動させる。しかし、ネスティング部１３２は、予め定められた特定の条件が成立したときに、特定の製品Ｐを示す図形を移動させることを中断してよい。例えば、ネスティング部１３２は、特定の製品Ｐを示す図形の移動を中断させる旨の入力がユーザーによってなされたときに、特定の製品Ｐを示す図形を移動させることを中断してよい。例えば、ネスティング部１３２は、特定の製品Ｐを示す図形の移動を開始した後に、予め定められた特定時間が経過したときに、特定の製品Ｐを示す図形を移動させることを自動的に中断してよい。例えば、ネスティング部１３２は、特定の製品Ｐを示す図形の移動させた回数が、予め定められた特定回数に達したときに、特定の製品Ｐを示す図形を移動させることを自動的に中断してよい。ネスティング部１３２は、特定の製品Ｐを示す図形を移動させることを自動的に中断するにあたり、アラームを出力してよい。 In the above embodiment and the above modification, the nesting unit 132 moves the figure representing the specific product P until the position of the protrusion T and the area that will become the hole H no longer overlap. However, the nesting unit 132 may stop moving the figure representing the specific product P when a specific predetermined condition is satisfied.

Move it again. However, the nesting unit 132 can perform different processing when the specific product P and another product P overlap after moving the graphic representing the specific product P. For example, in the example shown in FIG. 6, if the specific product P1 and another product P2 overlap after moving the figure indicating the specific product P1, the nesting unit 132 may remove the overlapping other product P2. You may move the shape that shows. In the example shown in FIG. 6, if the other product P2 and the other product P4 overlap after moving the figure representing the other product P2, the nesting unit 132 moves the other product P2 again. Alternatively, another product P4 may be moved.
