Abstract

A storage unit (11) stores: component data, including length, for each of a plurality of components as information relating to each component; and material data, including length and the number possessed, for each of a plurality of materials, as information relating to each material. A arrangement data preparation unit (121) selects a first usable material, which is the longest usable material among a plurality of usable materials, and performs nesting in which each component to be produced is arranged in the first usable material. When it is possible to arrange each component to be produced in a second usable material that is shorter than the first usable material, among the plurality of usable materials, while maintaining the condition of the disposition of the components to be produced disposed in the first usable material, the arrangement data preparation unit (121) performs a first post-process in which each component to be produced is arranged in the second usable material.

Description

配置データ作成装置及び配置データ作成方法Arrangement data creation device and arrangement data creation method
　本開示は、加工機によって所定長さのパイプまたは鋼材から複数の長さの部品を切断する際に用いる配置データを作成する配置データ作成装置及び配置データ作成方法に関する。 The present disclosure relates to an arrangement data creating apparatus and an arrangement data creating method for creating arrangement data used when a processing machine cuts a part having a plurality of lengths from a pipe or a steel material having a predetermined length.
　例えばレーザビームを用いてパイプまたは鋼材である材料を切断する加工機がある。この種の加工機は、ＮＣ装置によって制御される。ＮＣ装置は、材料を切断する処理の手順を規定する加工プログラムに従って加工機を制御する。加工機が材料を切断して複数の長さの部品を製作するとき、複数の長さの材料のうちのどの材料を選択して、選択した材料にそれぞれの長さの部品をどのように割り当てて材料を切断するかという配置を決める必要がある。材料に対する部品の配置はネスティングと称される。加工プログラムは、材料に対する部品のネスティングの状態を示す配置データに基づいて作成される。 加工 There are processing machines that cut materials such as pipes or steel using a laser beam, for example. This type of processing machine is controlled by an NC device. The NC device controls a processing machine in accordance with a processing program that defines a procedure of a process of cutting a material. When a machine cuts a material to produce parts of multiple lengths, it selects which of the multiple lengths of material and how to assign each length part to the selected material. It is necessary to determine the arrangement of cutting the material. The arrangement of parts relative to the material is called nesting.

　加工機によって材料を切断して部品を製作するとき、材料の歩留まり率を極力よくすることが求められる。ここでの歩留まり率とは、材料の長さに対する部品として使用された部分の割合であり、材料に対して残材の割合が多ければ歩留まり率が悪いということである。 切断 When manufacturing parts by cutting material with a processing machine, it is required to maximize the material yield rate.

The computer device 10 may be located at a remote location remote from the NC device 20 and connected to the NC device 20 via a network.
　コンピュータ機器１０は、ＣＡＭ（Computer Aided Manufacturing）として機能するコンピュータ機器である。コンピュータ機器１０は、記憶部１１と、中央処理装置（以下、ＣＰＵ）１２と、操作部１３と、表示部１４とを備える。記憶部１１には、部品データと、材料データと、配置データを作成するためのコンピュータプログラムである配置データ作成プログラムと、加工プログラムを作成するためのコンピュータプログラムである加工プログラム作成プログラムとが記憶されている。 The computer device 10 is a computer device that functions as a CAM (Computer Aided Manufacturing). The computer device 10 includes a storage unit 11, a central processing unit (hereinafter, CPU) 12, an operation unit 13, and a display unit 14. The storage unit 11 stores component data, material data, an arrangement data creation program that is a computer program for creating arrangement data, and a machining program creation program that is a computer program for creating a machining program. ing.
　部品データは複数の部品に関するデータであり、各部品に関する情報としての長さを含む。材料データは複数の材料に関するデータであり、各材料に関する情報としての長さ及び所有する本数を含む。 The component data is data on a plurality of components, and includes a length as information on each component. The material data is data on a plurality of materials, and includes the length as information on each material and the number of materials owned.
　部品データ及び材料データと、配置データ作成プログラム及び加工プログラム作成プログラムとが異なる記憶部に記憶されていてもよい。配置データ作成プログラム及び加工プログラム作成プログラムは、ＣＡＭプログラムである。 The component data and the material data, and the arrangement data creation program and the machining program creation program may be stored in different storage units. The arrangement data creation program and the machining program creation program are CAM programs.
　ＣＰＵ１２が配置データ作成プログラムを実行すると、ＣＰＵ１２は配置データ作成部１２１として機能する。ＣＰＵ１２が加工プログラム作成プログラムを実行すると、ＣＰＵ１２は加工プログラム作成部１２２として機能する。加工プログラム作成部１２２は、配置データ作成部１２１によって作成された配置データに基づいて、レーザ加工機３０が材料を切断する際に用いるＮＣデータよりなる加工プログラムを作成する。ＮＣデータはレーザ加工機３０を制御する機械制御コードである。 When the CPU 12 executes the placement data creation program, the CPU 12 functions as the placement data creation unit 121. When the CPU 12 executes the machining program creation program, the CPU 12 functions as a machining program creation unit 122. The processing program creation unit 122 creates a processing program including NC data used when the laser processing machine 30 cuts a material, based on the arrangement data created by the arrangement data creation unit 121. The NC data is a machine control code for controlling the laser beam machine 30.
　材料を切断して所定の部品を製作しようとするとき、オペレータが操作部１３によってネスティング計画を実行するよう操作すると、図２に示すように、表示部１４にはネスティング計画画像１４０が表示される。配置データ作成部１２１は、表示部１４にネスティング計画画像１４０を表示させる。ネスティング計画画像１４０は、製作しようとする部品の一覧を示す部品一覧領域１４１と、部品一覧領域１４１の部品を製作するために使用可能な材料（投入材料）の一覧を示す材料一覧領域１４２とを含む。 When an operator operates the operation unit 13 to execute a nesting plan when cutting a material to produce a predetermined part, a nesting plan image 140 is displayed on the display unit 14 as shown in FIG. . The arrangement data creation unit 121 causes the display unit 14 to display the nesting plan image 140. The nesting plan image 140 includes a parts list area 141 indicating a list of parts to be manufactured, and a materials list area 142 indicating a list of materials (input materials) that can be used to manufacture the parts in the parts list area 141. Including.
　図２に示すネスティング計画画像１４０は、オペレータが、記憶部１１に記憶されている部品データのうち、部品番号Ｐ－Ｘ、Ｐ－Ｙ、及びＰ－Ｚの部品を選択し、製作する員数をそれぞれ２個、２個、及び４個に設定した場合を示している。部品一覧領域１４１には、部品番号Ｐ－Ｘ、Ｐ－Ｙ、及びＰ－Ｚの各部品がパイプを切断した部品であることを示すマーク１４３が表示されている。 The nesting plan image 140 shown in FIG. 2 indicates that the operator selects the parts with the part numbers PX, XY, and PZ from the part data stored in the storage unit 11 and indicates the number of members to be manufactured. The case where two, two, and four are set respectively is shown. In the component list area 141, a mark 143 indicating that each component of the component numbers PX, PY, and PZ is a component obtained by cutting a pipe is displayed.
　配置データ作成部１２１は、部品番号Ｐ－Ｘ、Ｐ－Ｙ、及びＰ－Ｚの各部品を製作するために使用可能な材料を材料データより抽出して、材料一覧領域１４２に表示させる。部品番号Ｐ－Ｘ、Ｐ－Ｙ、及びＰ－Ｚの各部品は直径１００ｍｍ、板厚２ｍｍの部品であるから、使用可能な材料は直径１００ｍｍで板厚２ｍｍのパイプである。 (4) The arrangement data creation unit 121 extracts materials that can be used to manufacture the parts having the part numbers PX, PY, and PZ from the material data and displays the extracted materials in the material list area 142. Since the parts having the part numbers PX, PY, and PZ are parts having a diameter of 100 mm and a plate thickness of 2 mm, a usable material is a pipe having a diameter of 100 mm and a plate thickness of 2 mm.
　図２に示す例では、パイプ材料名称ＭＴ－ＰＡ、ＭＴ－ＰＢ、ＭＴ－ＰＸ、…のパイプが使用可能な材料として抽出されている。パイプ材料名称ごとに、材料の長さと所有する本数が表示されている。材料一覧領域１４２には、材料がパイプであることを示すマーク１４４が表示されている。マーク１４４はマーク１４３と同じでよい。 In the example shown in FIG. 2, pipes with pipe material names MT-PA, MT-PB, MT-PX,... Are extracted as usable materials. For each pipe material name, the length of the material and the number of tubes owned are displayed. In the material list area 142, a mark 144 indicating that the material is a pipe is displayed. The mark 144 may be the same as the mark 143.
　図３～図１２を用いて、歩留まり率を向上させるために、配置データ作成部１２１がどのようにネスティングを実行して配置データを作成するかを説明する。図３は、例１として、ネスティング計画に投入された投入部品が部品番号Ｐ－Ａ及びＰ－Ｂの部品であって、それらの部品を製作するために使用可能な投入材料が材料名称ＭＴ－Ａ及びＭＴ－Ｂの材料であった場合を示している。部品番号Ｐ－Ａ及びＰ－Ｂの部品が製作しようとする製作対象部品である。材料名称ＭＴ－Ａ及びＭＴ－Ｂの材料が、各製作対象部品を製作するために使用することができる使用可能材料である。 ～ With reference to FIGS. 3 to 12, a description will be given of how the arrangement data creation unit 121 executes nesting to create arrangement data in order to improve the yield rate. FIG. 3 shows an example 1 in which the input parts input to the nesting plan are the parts having the part numbers PA and PB, and the input materials usable for manufacturing those parts are the material names MT- A and MT-B materials are shown. The parts having the part numbers PA and PB are the parts to be manufactured. The materials having the material names MT-A and MT-B are usable materials that can be used to manufacture each component to be manufactured.
　部品番号Ｐ－Ａ及びＰ－Ｂの部品の部品長さはそれぞれ５００ｍｍ及び１６００ｍｍであり、各部品の員数は１である。材料名称ＭＴ－Ａ及びＭＴ－Ｂの材料の材料長さはそれぞれ２０００ｍｍ及び２５００ｍｍであり、各材料の本数は１である。 部品 The part lengths of the parts having the part numbers PA and PB are 500 mm and 1600 mm, respectively, and the number of parts is one. The material lengths of the materials with the material names MT-A and MT-B are 2000 mm and 2500 mm, respectively, and the number of each material is one.
　従来においては、使用可能な複数の投入材料が存在するときにオペレータによって投入材料の優先順位が設定され、優先順位に従って投入材料が選択されてネスティングが実行される。材料名称ＭＴ－Ａの材料が優先順位の最も高い優先順位１、材料名称ＭＴ－Ｂの材料が優先順位１よりも優先順位の低い優先順位２に設定されている場合を比較例とする。なお、オペレータは複数の投入材料に対して任意に優先順位を設定することができる。 Conventionally, when there are a plurality of usable input materials, the priority of the input materials is set by the operator, and the input materials are selected according to the priority and the nesting is performed. A comparative example is a case where the material having the material name MT-A is set to the highest priority 1 and the material having the material name MT-B is set to the second priority which is lower in priority than the first priority. The operator can arbitrarily set a priority order for a plurality of input materials.
　図４に示すように、比較例においては、部品番号Ｐ－Ｂの部品が材料名称ＭＴ－Ａの材料に自動的に配置され、部品番号Ｐ－Ａの部品が材料名称ＭＴ－Ｂの材料に自動的に配置される。なお、材料名称ＭＴ－Ａの材料に部品番号Ｐ－Ｂの部品を配置すると材料名称ＭＴ－Ａの材料には部品番号Ｐ－Ａの部品を配置できないため、部品番号Ｐ－Ａの部品は材料名称ＭＴ－Ｂの材料に配置される。 As shown in FIG. 4, in the comparative example, the part with the part number PB is automatically placed on the material with the material name MT-A, and the part with the part number PA is replaced with the material with the material name MT-B. Placed automatically. It should be noted that if the part with the part number PB is placed on the material with the material name MT-A, the part with the part number PA cannot be placed on the material with the material name MT-A. It is placed on the material with the name MT-B.
　比較例においては、材料名称ＭＴ－Ａの材料の歩留まり率は（１６００／２０００）×１００で８０％であり、材料名称ＭＴ－Ｂの材料の歩留まり率は（５００／２５００）×１００で２０％である。材料名称ＭＴ－Ａ及びＭＴ－Ｂの材料の平均歩留まり率は５０％である。 In the comparative example, the yield rate of the material with the material name MT-A is (1600/2000) × 100 and 80%, and the yield rate of the material with the material name MT-B is (500/2500) × 100 and 20%. It is. The average yield of the materials with the material names MT-A and MT-B is 50%.
　１またはそれ以上の実施形態においては、使用可能な複数の投入材料が存在するときに、最長の投入材料（第１の使用可能材料）が優先的に選択されて、ネスティングが実行される。図４に示すように、１またはそれ以上の実施形態においては、配置データ作成部１２１は例１における最長の投入材料である材料名称ＭＴ－Ｂの材料に部品番号Ｐ－Ｂ及びＰ－Ａの部品を配置する配置データを作成する。１またはそれ以上の実施形態においては、材料名称ＭＴ－Ｂの材料の歩留まり率は{（１６００＋５００）／２５００}×１００で８４％である。平均歩留まり率は５０％から８４％に改善される。 In one or more embodiments, when there is more than one available input material, the longest input material (first available material) is preferentially selected and nesting is performed. As shown in FIG. 4, in one or more embodiments, the arrangement data creating unit 121 assigns the longest input material in Example 1 the material with the material name MT-B and the part numbers PB and PA to the material. Create placement data for placing parts. In one or more embodiments, the yield of material with material name MT-B is {(1600 + 500) / 2500} × 100, which is 84%. The average yield is improved from 50% to 84%.
　図４に示すように、部品番号Ｐ－Ｂの部品と部品番号Ｐ－Ａの部品との間には、５～１０ｍｍ程度の隙間である部品間さん巾を設けている。歩留まり率の計算においては部品間さん巾を無視している。部品間さん巾は０に設定することも可能である。部品間さん巾及び歩留まり率の計算については他の図面においても同様である。 (4) As shown in FIG. 4, a part-to-part width, which is a gap of about 5 to 10 mm, is provided between the part having the part number PB and the part having the part number PA. In calculating the yield rate, the width between parts is ignored. The width between parts can be set to zero. The calculation of the width between parts and the yield rate is the same in other drawings.
　なお、部品長さまたは員数と材料長さとの関係によっては、最長の材料を優先的に選択してネスティングを実行することにより歩留まり率が改善されないことが起こり得る。しかしながら、本発明者による検証によって、最長の材料を優先的に選択してネスティングを実行することにより歩留まり率が改善されることが多いことが確認されている。よって、最長の投入材料を優先的に選択してネスティングを実行するのがよい。 Depending on the relationship between the component length or the number of members and the material length, the yield rate may not be improved by preferentially selecting the longest material and performing nesting. However, verification by the present inventors has confirmed that the yield rate is often improved by preferentially selecting the longest material and performing nesting. Therefore, it is preferable to perform nesting by preferentially selecting the longest input material.
　なお、最長の材料を優先的に選択しても歩留まり率が改善されない場合の歩留まり率の改善の処理については、後述する例２及び例３を用いて説明する。 The process of improving the yield rate when the yield rate is not improved even if the longest material is selected preferentially will be described using Examples 2 and 3 described later.
　図５は、例２として、ネスティング計画に投入された投入部品が部品番号Ｐ－Ｂの部品であって、それらの部品を製作するために使用可能な投入材料が材料名称ＭＴ－Ｃ及びＭＴ－Ａの材料であった場合を示している。部品番号Ｐ－Ｂの部品が製作対象部品である。材料名称ＭＴ－Ｃ及びＭＴ－Ａの材料が、製作対象部品を製作するために使用することができる使用可能材料である。 FIG. 5 shows, as an example 2, that the input parts input to the nesting plan are the parts having the part numbers PB, and the input materials that can be used for manufacturing these parts are the material names MT-C and MT-C. The case of the material A is shown. The part with the part number PB is the part to be manufactured. The materials with the material names MT-C and MT-A are usable materials that can be used to manufacture the component to be manufactured.
　部品番号Ｐ－Ｂの部品の部品長さは１６００ｍｍであり、員数は１である。材料名称ＭＴ－Ｃ及びＭＴ－Ｂの材料の材料長さはそれぞれ３０００ｍｍ及び２０００ｍｍであり、各材料の本数は１である。 部品 The part length of the part with the part number PB is 1600 mm and the number of parts is one. The material lengths of the materials having the material names MT-C and MT-B are 3000 mm and 2000 mm, respectively, and the number of each material is one.
　１またはそれ以上の実施形態においては、図６に示すように、配置データ作成部１２１は例２における最長の投入材料（第１の使用可能材料）である材料名称ＭＴ－Ｃの材料に部品番号Ｐ－Ｂの部品を配置する配置データを作成する。このとき、材料名称ＭＴ－Ｃの材料の歩留まり率は（１６００／３０００）×１００で５３％である。 In one or more embodiments, as shown in FIG. 6, the arrangement data creating unit 121 assigns the part number to the material having the material name MT-C, which is the longest input material (first usable material) in Example 2. The layout data for arranging the PB components is created. At this time, the yield rate of the material having the material name MT-C is (1600/3000) × 100, which is 53%.
　続けて、配置データ作成部１２１は、未使用の材料であって最長の投入材料よりも短い投入材料（第２の使用可能材料）が存在するときには、その短い投入材料に対して投入部品を配置する第１の後処理を実行する。例２では、配置データ作成部１２１は、材料名称ＭＴ－Ａの材料に部品番号Ｐ－Ｂの部品を配置する配置データを作成する。配置データ作成部１２１が投入部品を配置する投入材料を変更するとき、投入部品の配置の状態を変更せず維持する。 Subsequently, when there is an input material (a second usable material) that is an unused material and is shorter than the longest input material, the arrangement data creating unit 121 allocates the input component to the short input material. A first post-processing is performed. In Example 2, the arrangement data creating unit 121 creates arrangement data for arranging the part having the part number PB on the material having the material name MT-A. When the arrangement data creation unit 121 changes the input material on which the input component is to be arranged, the arrangement state of the input component is maintained without being changed.
　図７に示すように、配置データ作成部１２１が材料名称ＭＴ－Ａの材料に部品番号Ｐ－Ｂの部品を配置する配置データを作成すると、歩留まり率は（１６００／２０００）×１００で８０％となり、平均歩留まり率は５３％から８４％に改善される。 As shown in FIG. 7, when the arrangement data creation unit 121 creates the arrangement data for arranging the part with the part number PB on the material with the material name MT-A, the yield rate is (1600/2000) × 100 and 80%. And the average yield is improved from 53% to 84%.
　例１において、配置データ作成部１２１が第１の後処理を実行しないのは、図４における部品番号Ｐ－Ｂ及びＰ－Ａの２つ部品を、それらの配置の状態を変更しないで材料名称ＭＴ－Ａの材料に配置することができないからである。 In Example 1, the reason that the arrangement data creating unit 121 does not execute the first post-processing is that the two parts having the part numbers PB and PA in FIG. This is because it cannot be arranged on the material of MT-A.
　さらに、配置データ作成部１２１は、後述する第２の後処理を実行することが好ましい。配置データ作成部１２１は、第１の後処理を実行したか否かにかかわらず、第２の後処理を実行する。例３を用いて、配置データ作成部１２１が第２の後処理をどのように実行するかを説明する。 Furthermore, it is preferable that the arrangement data creating unit 121 executes a second post-process described later. The arrangement data creating unit 121 executes the second post-processing regardless of whether the first post-processing has been executed. Using Example 3, how the arrangement data creating unit 121 executes the second post-processing will be described.
　図８は、例３として、ネスティング計画に投入された投入部品が部品番号Ｐ－Ａ及びＰ－Ｂの部品であって、それらの投入部品を製作するために使用可能な投入材料が材料名称ＭＴ－Ｄ及びＭＴ－Ａの材料であった場合を示している。部品番号Ｐ－Ａ及びＰ－Ｂの部品が製作対象部品である。材料名称ＭＴ－Ｄ及びＭＴ－Ａの材料が、各製作対象部品を製作するために使用することができる使用可能材料である。 FIG. 8 shows, as Example 3, the input parts input to the nesting plan are the parts having the part numbers PA and PB, and the input materials that can be used to manufacture these input parts are the material names MT. This shows the case where the materials were -D and MT-A. The parts with the part numbers PA and PB are the parts to be manufactured. The materials with the material names MT-D and MT-A are usable materials that can be used to manufacture each component to be manufactured.
　部品番号Ｐ－Ａ及びＰ－Ｂの部品の部品長さはそれぞれ５００ｍｍ及び１６００ｍｍであり、員数はそれぞれ２及び４である。材料名称ＭＴ－Ｄ及びＭＴ－Ａの材料の材料長さはそれぞれ６０００ｍｍ及び２０００ｍｍであり、各材料の本数は２である。 部品 The part lengths of the parts having the part numbers PA and PB are 500 mm and 1600 mm, respectively, and the number of parts is 2 and 4, respectively. The material lengths of the materials with the material names MT-D and MT-A are 6000 mm and 2000 mm, respectively, and the number of each material is 2.
　図９に示すように、配置データ作成部１２１は例３における最長の投入材料である材料名称ＭＴ－Ｄの材料に部品番号Ｐ－Ａ及びＰ－Ｂの部品を配置する配置データを作成する。材料名称ＭＴ－Ｄの１本目の材料には、部品番号Ｐ－Ｂの部品が３つ配置され、２本目の材料には、部品番号Ｐ－Ｂの部品が１つ、部品番号Ｐ－Ａの部品が２つ配置される。このとき、１本目の材料の歩留まり率は｛（３×１６００）／６０００）｝×１００で８０％であり、２本目の材料の歩留まり率は｛（１６００＋２×５００）／６０００）｝×１００で４３％である。 As shown in FIG. 9, the arrangement data creation unit 121 creates arrangement data for arranging the parts having the part numbers PA and PB on the material having the material name MT-D, which is the longest input material in Example 3. In the first material having the material name MT-D, three parts having the part number PB are arranged. In the second material, one part having the part number PB and one having the part number PA are arranged. Two parts are arranged. At this time, the yield rate of the first material is {(3 × 1600) / 6000)} × 100 and 80%, and the yield rate of the second material is {(1600 + 2 × 500) / 6000) × 100. 43%.
　例３においては第１の後処理を実行することができないため、最長の投入材料に投入部品が配置された状態で、配置データ作成部１２１は、投入部品が配置されている複数の投入材料のうち、歩留まり率が最も低く、かつ、歩留まり率が所定の基準値未満の材料に対して、第２の後処理を実行する。１またはそれ以上の実施形態においては、基準値を８０％とする。 In Example 3, since the first post-processing cannot be executed, the arrangement data creating unit 121 in a state where the input components are arranged in the longest input material, outputs a plurality of input materials in which the input components are arranged. The second post-processing is performed on a material having the lowest yield rate and a yield rate less than a predetermined reference value. In one or more embodiments, the reference value is 80%.
　具体的には、配置データ作成部１２１は、歩留まり率が最も低く、かつ、歩留まり率が基準値未満の投入材料（以下、歩留まり率最低材料）に配置された部品を、歩留まり率最低材料の材料長さより短い未使用の材料に配置するネスティングを実行する。配置データ作成部１２１は、歩留まり率最低材料の材料長さより短い材料が複数存在する場合には、材料長さが長い材料から短い材料へと順にネスティングを実行する。 More specifically, the arrangement data creation unit 121 determines the parts arranged in the input material having the lowest yield rate and the yield rate less than the reference value (hereinafter, the lowest yield rate material) as the material of the lowest yield rate material. Perform nesting placing on unused material shorter than the length. When there are a plurality of materials shorter than the material length of the lowest yield rate material, the arrangement data creating unit 121 performs the nesting in order from the material having the longer material length to the material having the shorter material length.
　第１の後処理が実行された場合には、最長の投入材料より短い投入材料に投入部品が配置された状態で、配置データ作成部１２１は、投入部品が配置されている複数の投入材料のうち、歩留まり率が最も低く、かつ、歩留まり率が所定の基準値未満の材料に対して、第２の後処理を実行すればよい。 When the first post-processing is executed, the arrangement data creating unit 121, in a state where the input components are arranged in the input material shorter than the longest input material, outputs a plurality of input materials in which the input components are arranged. The second post-processing may be performed on a material having the lowest yield rate and a yield rate less than a predetermined reference value.
　図９に示すように、例３において、材料名称ＭＴ－Ｄの２本目の材料の歩留まり率が最も低く、かつ、歩留まり率が８０％未満である。図１０に示すように、２本目の材料に配置された投入部品は、部品番号Ｐ－Ａの部品が２つ、部品番号Ｐ－Ｂの部品が１つである。歩留まり率最低材料の材料長さより短い未使用の材料は、材料名称ＭＴ－Ａの材料であり、２本存在している。 As shown in FIG. 9, in Example 3, the yield rate of the second material having the material name MT-D is the lowest, and the yield rate is less than 80%. As shown in FIG. 10, the input parts arranged in the second material have two parts with the part number PA and one part with the part number PB. An unused material shorter than the material length of the lowest yield rate material is a material having a material name of MT-A, and two materials exist.
　図１１に示すように、配置データ作成部１２１は、第２の後処理として、材料名称ＭＴ－Ａの１本目の材料に部品番号Ｐ－Ｂの部品を１つ配置し、２本目の材料に部品番号Ｐ－Ａの部品を２つ配置するネスティングを実行する。このとき、１本目の材料の歩留まり率は（１６００／２０００）×１００で８０％であり、２本目の材料の歩留まり率は（２×５００／２０００）×１００で５０％である。２本の材料の平均歩留まり率は６５％である。 As shown in FIG. 11, as a second post-process, the arrangement data creating unit 121 arranges one part having the part number PB on the first material having the material name MT-A, and Nesting for arranging two parts with the part number PA is executed. At this time, the yield rate of the first material is (1600/2000) × 100 and 80%, and the yield rate of the second material is (2 × 500/2000) × 100 and 50%. The average yield of the two materials is 65%.
　以上によって、配置データ作成部１２１は、例３において最終的に図１２に示す配置データを作成する。材料名称ＭＴ－Ｄの１本の材料に部品番号Ｐ－Ｂの部品が３つ配置され、材料名称ＭＴ－Ａの１本目の材料に部品番号Ｐ－Ｂの部品が１つ配置され、材料名称ＭＴ－Ａの２本目の材料に部品番号Ｐ－Ａの部品が２つ配置される。第２の後処理を実行することにより平均歩留まり率は６１．５％から７０％に改善される。 {As a result, the arrangement data creation unit 121 finally creates the arrangement data shown in FIG. Three parts having the part number PB are arranged in one material having the material name MT-D, and one part having the part number PB is arranged in the first material having the material name MT-A. Two parts with the part number PA are arranged in the second material of the MT-A. By performing the second post-processing, the average yield is improved from 61.5% to 70%.
　図１３Ａ及び図１３Ｂに示すフローチャートを用いて、ＣＰＵ１２（配置データ作成部１２１）が実行する配置データの作成処理を説明する。図１３Ａにおいて、ＣＰＵ１２は、ステップＳ１にて、最長の投入材料に投入部品を自動的に配置する自動ネスティングを実行する。ＣＰＵ１２は、ステップＳ２にて、第１の後処理が実行可能か否かを判定する。第１の後処理が実行可能であれば（YES）、ＣＰＵ１２は、ステップＳ３にて、第１の後処理を実行して、処理をステップＳ４に移行させる。ステップＳ２にて第１の後処理が実行可能でなければ（NO）、ＣＰＵ１２は処理をステップＳ４に移行させる。 A description will be given, with reference to the flowcharts shown in FIGS. In FIG. 13A, in step S1, the CPU 12 executes automatic nesting for automatically arranging the input components on the longest input material. In step S2, the CPU 12 determines whether the first post-processing can be executed. If the first post-processing is executable (YES), the CPU 12 executes the first post-processing in step S3, and shifts the processing to step S4. If the first post-processing cannot be executed in step S2 (NO), the CPU 12 shifts the processing to step S4.
　ＣＰＵ１２は、ステップＳ４にて、投入部品が配置された各材料の歩留まり率を算出し、ステップＳ５にて、歩留まり率最小の材料の歩留まり率ＵＴＬが８０％未満であるか否かを判定する。ＵＴＬは変数である。歩留まり率ＵＴＬが８０％未満でなければ（NO）、ＣＰＵ１２は処理を終了させる。 (4) In step S4, the CPU 12 calculates the yield rate of each material on which the input components are arranged, and determines in step S5 whether the yield rate UTL of the material having the smallest yield rate is less than 80%. UTL is a variable. If the yield rate UTL is not less than 80% (NO), the CPU 12 ends the processing.
　歩留まり率ＵＴＬが８０％未満であれば（YES）、ＣＰＵ１２は、図１３Ｂに示すステップＳ６にて、第２の後処理で使用可能な投入材料があるか否かを判定する。第２の後処理で使用可能な投入材料があれば（YES）、ＣＰＵ１２は、ステップＳ７にて、第２の後処理を実行する。第２の後処理で使用可能な投入材料がなければ（NO）、ＣＰＵ１２は処理をステップＳ１３に移行させる。 If the yield rate UTL is less than 80% (YES), the CPU 12 determines in step S6 shown in FIG. 13B whether or not there is an input material that can be used in the second post-processing. If there is an input material that can be used in the second post-processing (YES), the CPU 12 executes the second post-processing in step S7. If there is no usable input material in the second post-processing (NO), the CPU 12 shifts the processing to step S13.
　ＣＰＵ１２は、ステップＳ７に続けてステップＳ８にて、第２の後処理の対象の全ての投入部品を、第２の後処理で使用可能と判定された投入材料に配置可能であるか否かを判定する。第２の後処理の対象の全ての投入部品を投入材料に配置可能であれば（YES）、ＣＰＵ１２は、ステップＳ９にて、第２の後処理の対象の投入部品を配置した投入材料における平均歩留まり率ＵＴＬaveを算出する。ＵＴＬaveは変数である。ステップＳ８にて、第２の後処理の対象の全ての投入部品を投入材料に配置可能でなければ（NO）、ＣＰＵ１２は処理をステップＳ１３に移行させる。 In step S8 following step S7, the CPU 12 determines whether or not all the input parts to be subjected to the second post-processing can be arranged on the input materials determined to be usable in the second post-processing. judge. If all the input components to be subjected to the second post-processing can be arranged in the input material (YES), the CPU 12 determines in step S9 the average of the input components to which the input components to be subjected to the second post-processing have been arranged. The yield rate UTLave is calculated. UTLave is a variable. In step S8, if it is not possible to arrange all the input parts to be subjected to the second post-processing on the input material (NO), the CPU 12 shifts the processing to step S13.
　ステップＳ８にて第２の後処理の対象の全ての投入部品を投入材料に配置可能でないと判定されるのは、図１４または図１５のような場合である。図１４は、第２の後処理で使用しようとする投入材料が投入部品よりも短い場合を示している。図１５は、一例として、投入部品を投入材料に１０個配置しなければならないのに９個しか配置できず、全ての投入部品を投入材料に配置できない場合を示している。 に て It is determined in step S8 that all the input components to be subjected to the second post-processing cannot be arranged on the input material in the case as shown in FIG. 14 or FIG. FIG. 14 shows a case where the input material to be used in the second post-processing is shorter than the input component. FIG. 15 shows, as an example, a case in which ten input components must be arranged in the input material, but only nine components can be arranged, and not all the input components can be arranged in the input material.
　図１３Ｂに戻り、ＣＰＵ１２は、ステップＳ１０にて、平均歩留まり率ＵＴＬaveが歩留まり率ＵＴＬより大きいか否かを判定する。平均歩留まり率ＵＴＬaveが歩留まり率ＵＴＬより大きくなければ（NO）、歩留まり率最小の投入材料の歩留まり率ＵＴＬは改善していないということであり、ＣＰＵ１２は、処理をステップＳ６に戻して、ステップＳ６以降を繰り返す。 13B, in step S10, the CPU 12 determines whether the average yield rate UTLave is greater than the yield rate UTL. If the average yield rate UTLave is not larger than the yield rate UTL (NO), it means that the yield rate UTL of the input material having the smallest yield rate has not been improved, and the CPU 12 returns the processing to step S6 and returns to step S6 and thereafter. repeat.
　ＣＰＵ１２は、歩留まり率最低材料より短い投入材料が複数存在する場合には、材料長さが長い材料から短い材料へと順に選択してステップＳ７の第２の後処理を実行する。よって、第２の後処理は、複数回実行されることがある。 If there are a plurality of input materials that are shorter than the lowest yield rate material, the CPU 12 sequentially selects the material having the longer material length to the shorter material, and executes the second post-processing of Step S7. Therefore, the second post-processing may be executed a plurality of times.
　図１６は、第２の後処理が複数回実行される場合の一例を示している。図１３ＡのステップＳ１における自動ネスティング及びステップＳ３における第１の後処理を実行した結果、材料名称ＭＴ－Ａ及びＭＴ－Ｂの材料が使用され、ＭＴ－Ｂの材料が歩留まり率最低材料であったとする。この場合、未使用の材料のうち、歩留まり率最低材料より短い材料名称ＭＴ－Ｄ、ＭＴ－Ｅ、ＭＴ－Ｆ、及びＭＴ－Ｇの材料が第２の後処理で使用可能な投入材料となる。 FIG. 16 shows an example in which the second post-processing is executed a plurality of times. As a result of executing the automatic nesting in step S1 of FIG. 13A and the first post-processing in step S3, the materials with the material names MT-A and MT-B were used, and the material with MT-B was the material with the lowest yield rate. I do. In this case, among the unused materials, materials having material names MT-D, MT-E, MT-F, and MT-G, which are shorter than the lowest yield rate material, are input materials that can be used in the second post-processing. .
　１回目の第２の後処理として、例えば材料名称ＭＴ－Ｄの材料が選択されて第２の後処理が実行される。平均歩留まり率ＵＴＬaveが歩留まり率ＵＴＬより大きくなければ、材料名称ＭＴ－Ｄの材料より短い材料名称ＭＴ－Ｆ及びＭＴ－Ｇの材料が２回目の第２の後処理で使用可能な材料となる。 (4) As the first second post-processing, for example, the material having the material name MT-D is selected and the second post-processing is executed. If the average yield rate UTLave is not larger than the yield rate UTL, the materials having the material names MT-F and MT-G, which are shorter than the material having the material name MT-D, can be used in the second second post-processing.
　２回目の第２の後処理として、材料名称ＭＴ－Ｆの材料が選択されて第２の後処理が実行される。平均歩留まり率ＵＴＬaveが歩留まり率ＵＴＬより大きくなければ、材料名称ＭＴ－Ｆの材料より短い材料名称ＭＴ－Ｇの材料が３回目の第２の後処理で使用可能な材料となる。３回目の第２の後処理として、材料名称ＭＴ－Ｇの材料が選択されて第２の後処理が実行される。 材料 As the second post-processing, the material having the material name MT-F is selected and the second post-processing is executed. If the average yield rate UTLave is not larger than the yield rate UTL, a material having a material name MT-G shorter than the material having the material name MT-F becomes a material that can be used in the third second post-processing. As the third second post-processing, the material having the material name MT-G is selected and the second post-processing is executed.
　図１３Ｂに戻り、ステップＳ１０にて平均歩留まり率ＵＴＬaveが歩留まり率ＵＴＬより大きければ（YES）、ＣＰＵ１２は、ステップＳ１１にて、歩留まり率ＵＴＬ（変数ＵＴＬ）を平均歩留まり率ＵＴＬave（変数ＵＴＬave）に設定する。ＣＰＵ１２は、ステップＳ１１に続けてステップＳ１２にて、歩留まり率ＵＴＬが８０％以上であるか否かを判定する。歩留まり率ＵＴＬが８０％以上でなければ（NO）、ＣＰＵ１２は、処理をステップＳ６に戻して、ステップＳ６以降を繰り返す。 Returning to FIG. 13B, if the average yield rate UTLave is larger than the yield rate UTL in step S10 (YES), the CPU 12 sets the yield rate UTL (variable UTL) to the average yield rate UTLave (variable UTLave) in step S11. I do. In step S12 following step S11, the CPU 12 determines whether or not the yield rate UTL is 80% or more. If the yield rate UTL is not 80% or more (NO), the CPU 12 returns the processing to step S6 and repeats the processing from step S6.
　ステップＳ１２にて歩留まり率ＵＴＬが８０％以上であれば（YES）、ＣＰＵ１２は、ステップＳ１３にて、歩留まり率ＵＴＬがステップＳ５における歩留まり率ＵＴＬと同じであるか否かを判定する。第２の後処理で使用可能な投入材料がない場合、第２の後処理の対象の全ての投入部品を第２の後処理で使用可能と判定された投入材料に配置可能でない場合には、歩留まり率ＵＴＬはステップＳ５における歩留まり率ＵＴＬと同じとなる。 If the yield rate UTL is 80% or more in step S12 (YES), the CPU 12 determines in step S13 whether the yield rate UTL is the same as the yield rate UTL in step S5. If there is no input material that can be used in the second post-processing, if not all the input components to be subjected to the second post-processing can be placed on the input material determined to be usable in the second post-processing, The yield rate UTL is the same as the yield rate UTL in step S5.
　歩留まり率ＵＴＬが８０％以上であるときステップＳ１３に移行させるのは、仮に第２の後処理で使用可能な投入材料が残っていたとしても、それ以上第２の後処理を実行する必要はないからである。ステップＳ１３にて歩留まり率ＵＴＬがステップＳ５における歩留まり率ＵＴＬと同じであれば（YES）、ＣＰＵ１２は処理を終了させる。 When the yield rate UTL is 80% or more, the process proceeds to step S13. Even if the input materials usable in the second post-processing remain, there is no need to execute the second post-processing any more. Because. If the yield rate UTL is the same as the yield rate UTL in step S5 in step S13 (YES), the CPU 12 terminates the processing.
　ステップＳ１３にて歩留まり率ＵＴＬがステップＳ５における歩留まり率ＵＴＬと同じでなければ（NO）、歩留まり率最低材料の歩留まり率ＵＴＬが改善したということであり、ＣＰＵ１２は、ステップＳ１４にて、第２の後処理を実行した状態を最終的なネスティングと決定して処理を終了させる。 If the yield rate UTL is not the same as the yield rate UTL in step S5 in step S13 (NO), it means that the yield rate UTL of the material having the lowest yield rate has been improved, and the CPU 12 determines in step S14 that The state in which the post-processing has been executed is determined as the final nesting, and the processing ends.
