Description

[Technical Field]

[0001] The present disclosure relates to a jig model creation device for a jig, a jig model creation method, and a program. [Background technology]

[0002] Aircraft manufacturing involves handling components ranging from small parts approximately 100 mm to large parts exceeding 10 m in size, with the goal of reducing weight and optimizing structure. Each part has a unique shape, and some even have complex geometries. This requires numerous jigs for manufacturing and inspecting aircraft structural components. Meanwhile, aircraft structures are semi-monocoque, with structural strength ensured by step-by-step assembly of individual components. For example, during the assembly process, non-rigid components are drilled and then joined with bolts and fasteners to create rigid components. Large-scale jigs are used to ensure the precision of the aircraft's exterior shape. Furthermore, additional processing is often performed on components at each stage leading up to the final assembly, requiring specialized machining tools for each stage. Thus, numerous jigs, large and small, are used in the component manufacturing and assembly processes for aircraft. The aircraft development process, from initial design to final drawings, improves precision step by step. The aircraft specifications defined by the design are for the final assembly, while the specifications for each assembly step and individual component must be broken down to take the manufacturing process into account. Therefore, the precision of jig design will also be improved in stages in line with the aircraft design. In aircraft manufacturing, efficient jig design and manufacturing methods are required to reduce development lead times. In order to shorten development lead times, it is common to start designing the above jig from the initial design stage. Furthermore, in order to quickly manufacture the first aircraft after the aircraft design is complete, it is necessary to start arranging the jig before the jig design is complete.

[0003] Patent Document 1 discloses a method for creating a manufacturing BOM (Bill of Materials) that creates a manufacturing BOM from a design BOM during the product design stage, making it possible to proceed with outsourcing arrangements for product manufacturing, unit manufacturing, etc., before the design is complete. The technology described in Patent Document 1 does not relate to creating a BOM for aircraft jigs. [Prior art documents] [Patent documents]

[0012] <Embodiment> Hereinafter, a method for creating a jig model for an aircraft according to the present disclosure will be described with reference to FIGS. (composition) FIG. 1 is a block diagram showing an example of a jig model creating device according to an embodiment. The jig model creation device 10 is configured with one or more computers. As shown in the figure, the jig model creation device 10 includes an input receiving unit 11, an aircraft model acquisition unit 12, a layout model creation unit 13, a manufacturing model creation unit 14, a BOM generation unit 15, a capture generation unit 16, an output unit 17, and a storage unit 18. The layout model creation unit 13 and the manufacturing model creation unit 14 are configured to include, for example, CAD software.

[0013] The input accepting unit 11 accepts various information input using an input device such as a keyboard, mouse, touch panel, or button, as well as instruction information instructing the start and end of processing. For example, the input accepting unit 11 accepts various information about aircraft manufacturing jigs (e.g., name, identification number, type, weight, quantity, parts constituting the jig, material, shape, processing and assembly methods, etc.) input to the jig model creation device 10. The input accepting unit 11 also accepts the setting of links between the aircraft model, layout model, and manufacturing model, which will be described later. A link is a setting that is made, for example, when the configuration of the aircraft model is associated with a part of the configuration of the layout model and the design information of the associated part is to be linked and synchronized. By setting a link, when the configuration of the aircraft model is changed, the change can be automatically reflected in the related configuration of the layout model. In this embodiment, a link copy (described later) may be used as one form of link.

[0014] The aircraft model acquisition unit 12 acquires an aircraft model created by a designer that shows the aircraft's final assembled state. The aircraft model includes 3D model information that shows the aircraft's shape when completed, as well as assembly information such as connection information for fasteners and bolts, and positioning information for shims and sealants. The aircraft model is modified and added to according to each design phase, from initial design to final drawings.

[0015] Based on instructions from the jig designer, the layout model creation unit 13 creates a layout model, which is design data for jigs required for manufacturing the aircraft, and adds the layout model to the portion of the aircraft model where the jigs are used. The layout model is a model that defines the shape and structure of the jig by linking it to the aircraft model and production equipment model. The jig designer defines the jig shape and position by link-copying necessary elements (e.g., reference datums such as aircraft surfaces, reference planes, and reference holes) from the aircraft model. The layout model creation unit 13 creates data by link-copying the aircraft model and adds the defined jig shape and other information to the created data to create a layout model. When the design of the aircraft model is changed, the aircraft model and the linked-copied information in the layout model are automatically updated. Link copy is a function provided, for example, in CAD software. When the position or size of a certain element A (e.g., an aircraft fuselage panel) is changed in the aircraft model, the changes are automatically reflected in element A of the linked copy data. By utilizing this function, changes to the aircraft model can be automatically reflected in the layout model. The link copy function is not limited to the functions of the CAD software. For example, a function may be implemented in which the identification number of element A in the link copy destination data and the identification number of element A in the copy source aircraft model are associated and managed, and a change to element A in the aircraft model is used as a trigger to reflect the change made to the aircraft model in element A of the link copy destination data in the layout model having the corresponding identification number. In addition, the layout model creation unit 13 sets links between predetermined design information within the layout model, and when the aircraft model is changed, all jig design information affected by the change is updated.

[0016] Based on instructions from the jig designer, the manufacturing model creation unit 14 extracts and links only jig information from the layout model, and adds more specific information required for jig manufacturing (such as the names, model numbers, quantities, weights, and part processing methods of the components that make up the jig) to create a jig manufacturing model. A manufacturing model is a model in which jig configuration data is linked and copied from the layout model and organized in a tree structure. The manufacturing model can be used for jig manufacturing, production simulation, and confirmation work using VR (Virtual Reality). The manufacturing model is defined separately for a manufacturing configuration model, an instruction manual (sometimes referred to as a manual) that describes how to use the manufactured jig at the aircraft manufacturing site, and inspection data required for jig inspection. The inspection data is used as a standard for maintaining jig accuracy and includes measurement surfaces and coordinates. The manufacturing model is lightweight data that does not include design know-how information such as design history information for the aircraft model and jig model, and only extracts information necessary for jig manufacturing and inspection. The manufacturing model is handed over to a jig manufacturer, for example, but by separating it from the aircraft model and layout model and specializing it only in the information necessary for jig manufacturing, it is possible to prevent the leakage of confidential design information and know-how, etc. In addition, because it is lightweight data, it is easy to handle when used for production simulations and VR.

[0017] The BOM generation unit 15 generates a BOM (Bill of Materials) that is a list of parts and the like required for manufacturing the jig from the manufacturing model. The capture generation unit 16 generates captures registered in the manufacturing model. Captures are various technical instructions for individual parts or assemblies that make up the jig, such as shape, specifications, geometric dimensional tolerances, and processing instructions for welding and surface treatment. The output unit 17 outputs the aircraft model, layout model, manufacturing model, BOM, etc. to a display device, electronic file, etc. The storage unit 18 stores an aircraft model, a layout model, a manufacturing model, and the like.

[0018] Figure 2 shows an overview of the process for creating manufacturing models, etc. First, an aircraft model is created using CAD software. The aircraft model includes an assembly model (what parts the assembly is made up of), part models for each part (part type, size, etc.), aircraft surfaces, reference surfaces (surfaces that serve as references when placing parts), reference hole positions, and other reference standards. The aircraft model is used for type certification, etc. Once the aircraft model is created, a layout model is created without waiting for the aircraft drawings to be released. The layout model is created by linking and copying the necessary information from the aircraft model.

[0019] The layout model includes information about the machine, equipment, related design models, jig reference surfaces, correction surfaces, and basic layouts. Once the layout model is created, the jig designer uses CAD software to study and design the jig in detail. As a result, the layout model contains rough jig design information. The manufacturing model is created by linking and copying the jig design data from the layout model. However, the layout model's historical information is removed and only the final design solid data is extracted to create the manufacturing model. The layout model and the manufacturing model, which defines the information for jig manufacturing, are created separately, although they share some links. The layout model includes information about the machine and equipment, as well as jig design information, while the manufacturing model contains only the information necessary for jig manufacturing and inspection. This prevents the leakage of machine information and design know-how to jig manufacturers, overseas manufacturers, etc.

[0020] The manufacturing model includes information such as basic jig information, jig configuration model, component parts, models, parameters, and jig instruction manual models. Jig designers use CAD software to create a tree structure for the manufacturing model while also defining model-based BOM information. Basic jig information, such as jig specifications and notes, overall jig processing instructions, and the part of the aircraft the jig is used for, are defined on the model (e.g., a 3D CAD model). The jig configuration model defines the necessary information (shape, specifications, quantity, position, etc.) using models or parameters depending on the design phase and type of jig components, and generates BOMs and captures directly from the jig configuration model. Components include assembled products, manufactured products, and purchased / standard products. Assembled products are further classified into connected products, which are assembled by connecting them with bolts, etc., and welded products, which are assembled by connecting them with welding. Purchased / standard products are further classified into those that require additional processing and those that do not. For assemblies and manufactured products that require manufacturing, the position and shape are defined in the model, and specifications (quantity, material size, etc.) are defined using the model and parameters. For purchased / standard products that do not need to be modeled, the model number and quantity are defined using parameters only. However, for purchased / standard products that require interference checks, placement instructions, or additional processing, models are created. When the aircraft model or layout model is changed, the manufacturing model is automatically updated via links. By changing the way part specifications are defined in the manufacturing model depending on the design phase and type of jig components at each stage from initial design to final drawings, it is possible to automatically generate BOMs and captures according to the design phase.

[0021] The BOM includes the type, quantity, and specifications of components. The capture includes the manufacturing specifications and technical requirements for the jigs and the parts that make up the jigs. By updating the shape and specification definitions according to each design phase and automatically generating the BOM each time, it is possible to manufacture the jigs (procurement, assembly, inspection) in parallel with the jig design. In addition, by automatically generating a capture each time a design change is made, it is possible to update the work instruction information for jig manufacturing and inspection.

[0022] 3A to 3C show examples of components constituting an aircraft and the appearance of jigs required for manufacturing these components. FIG. 3A shows an aircraft fuselage panel 1 as an example of an aircraft model. An aircraft designer designs the aircraft fuselage panel 1. The aircraft model acquisition unit 12 acquires the aircraft model shown in FIG. 3A. Next, based on instructions from the jig designer, the layout model creation unit 13 creates a layout model by link-copying the aircraft model. Based on the aircraft fuselage panel 1 included in the created layout model, the jig designer designs an aircraft fuselage panel assembly jig 2 required for manufacturing the aircraft fuselage panel 1. The layout model creation unit 13 adds design data for the aircraft fuselage panel assembly jig 2 to the layout model based on the jig designer's design. FIG. 3B shows an example of a layout model created by the layout model creation unit 13. The layout model in FIG. 3B includes the aircraft fuselage panel 1 and the aircraft fuselage panel assembly jig 2. FIG. 3C shows a three-dimensional model of the aircraft fuselage panel assembly jig 2.

[0023] Layout models of the portion indicated by "A" in FIGS. 3B and 3C are shown in FIGS. 4A to 4C. FIG. 4A shows the layout model of portion "A" before the aircraft model is changed. In FIG. 4A, the end face 22 of the aircraft fuselage panel 1 and the locator 21 of the aircraft fuselage panel assembly jig 2 are in contact. Next, assume that a design change occurs in the aircraft model, causing the position of the aircraft fuselage panel 1 to change. If the aircraft fuselage panel 1 in the layout model was created by link-copying the aircraft fuselage panel 1 in the aircraft model, the design change of the aircraft fuselage panel 1 is automatically reflected in the layout model. FIG. 4B shows an example of a layout model after the design change of the aircraft fuselage panel 1. As shown in the figure, due to the design change in the position of the aircraft fuselage panel 1, the aircraft fuselage panel 1 and the locator 21 interfere with each other in FIG. 4B. The jig designer corrects the position of the locator 21 by referring to FIG. 4B. Alternatively, when creating a layout model, by setting (setting a link) the position of end face 22 of locator 21 in association with the position of aircraft fuselage panel 1 so that end face 22 does not interfere with aircraft fuselage panel 1, it is possible to change the layout model so that when the design of aircraft fuselage panel 1 is changed, the position of locator 21 is automatically adjusted to the position shown in Fig. 4C. Next, we will explain how the design change process illustrated in Fig. 4A to 4C is automated by the links set in the layout model and the manufacturing model.

[0024] FIG. 5 shows an example of the tree structure of the aircraft model, layout model, and manufacturing model. The jig model includes a layout model (a tree structure under LYOT.CATProduct) and a manufacturing model (a tree structure under DWG.CATProduct). Note that the "CATProduct" in LYOT.CATProduct or DWG.CATProduct, or the "CATPart" in NOTE.CATPart, etc., which will be described later, indicates a file of CATIA (registered trademark), a CAD software. In the description of this embodiment, CATIA (registered trademark) is used as an example. However, the software used is not limited to CATIA (registered trademark). Other CAD software may also be used. The functions of this embodiment may also be realized using software other than CAD software. The tree structure of the aircraft model in FIG. 5 is information that can be set on the same screen while displaying the 3D model illustrated in FIG. 3A. Similarly, the tree structures of the layout model and manufacturing model illustrated in FIG. 5 are information that can be set on the same screen while displaying the 3D models of the layout model and manufacturing model, respectively. The aircraft model, layout model, and manufacturing model each include both a 3D model and a tree structure.

[0025] As shown in the figure, the layout model (LYOT.CATProduct) includes the aircraft model (ENG.CATProduct), the equipment information and related fixture model (LREF.CATProduct), the related design model (RLM.CATProduct), and the basic layout model (TLM.CATProduct). The aircraft model includes assembly models of the aircraft parts related to the fixtures linked and copied from the aircraft model. The equipment information and related fixture model includes related data required for jig design (equipment information such as machine tools, tools, and factories used to manufacture the fixtures, and information on related fixtures). The related design model defines the relationship between the aircraft model and jig model (such as their positional relationship), as well as the jig's reference surface and correction surface. The basic layout model defines the basic shape of the jig. Jig designers primarily design jigs by creating the basic layout model.

[0026] The manufacturing model (DWG.CATProduct) includes the jig basic information (NOTE.CATPart), the jig configuration model (TOOL.CATProduct), the jig instruction manual model (DREF.CATProduct), and the inspection and inspection model (INSP.CATProduct). The jig basic information includes basic information such as jig specifications and notes. The jig configuration model includes data necessary for manufacturing the jig. The jig instruction manual model includes data that represents the jig assembly drawing. The inspection and inspection model includes data necessary for inspecting the jig.

[0027] Figure 5 shows the links between the tree structures for each model. A link is established between the aircraft fuselage panel in the aircraft model and the aircraft model in the layout model. A link indicates a relationship in which changes to the link source are reflected in the link destination; link copy is an example of this. When a link is established, for example, if the information in the link source is changed from information 1 to information 2, the information in the link destination is also changed from information 1 to information 2. Alternatively, when a link is established, the information in the link source (e.g., location information) and the information in the link destination have a fixed relationship, and if the information in the link source is updated, the information in the link destination is also updated while maintaining a fixed relationship with the link source. The jig designer can arbitrarily define the relationship between the link source and the link destination. For example, the aircraft fuselage panel in the aircraft model in Figure 5 is the link source, and the aircraft model in the layout model is the link destination. This link is established by link copy. Similarly, links are established between the layout model's aircraft model (link source) and the layout model's related design model (link destination), between the layout model's equipment information and related fixture model (link source) and the layout model's related design model (link destination), between the layout model's related design model (link source) and the layout model's base layout model (link destination), and between the layout model's base layout model (link source) and the manufacturing model's fixture configuration model (link destination). For example, in the link between the layout model's aircraft model and the related design model, the surface of the aircraft fuselage panel 1 facing the locator 21 ( FIG. 4A ) is linked to the fixture reference surface (the surface serving as the reference for placing the fixture), and the two are set to have a fixed positional relationship. Furthermore, in the basic layout model, the position of the end face 22 of the locator 21 is set based on the fixture reference surface.

[0028] Based on these links, the processes shown in Figures 4A to 4C will be explained from the perspective of tree structures. Figures 6A and 6B show the tree structures related to the layout model and the manufacturing model. In this link relationship, if only the aircraft model is changed, the jig model will not be updated, resulting in the interference state shown in Figure 4B. Next, when a model is updated based on the links in the layout model, the changes to the aircraft model are reflected in the aircraft model (ENG.CATProduct) in the layout model, the changes to the aircraft model (ENG.CATProduct) are reflected in the related design model (RLM.CATProduct), and the changes to the related design model (RLM.CATProduct) are reflected in the basic layout model (TLM.CATProduct). If the links between the aircraft model and the related design model (RLM.CATProduct) in the layout model are set so that the aircraft fuselage panel 1 and the jig reference surface have a fixed positional relationship, the change in the position of the aircraft fuselage panel 1 in the aircraft model is reflected in the jig reference surface, and the jig reference surface also moves in accordance with the position of the aircraft fuselage panel 1. Accordingly, the position of the locator 21, which is positioned based on the jig reference surface, is also modified. Next, when the manufacturing model is updated based on the link, the changes to the layout model's basic layout model (TLM.CATProduct) are reflected in the manufacturing model's jig configuration model (TOOL.CATProduct). The changes to the basic layout model are also reflected in the linked elements of the jig instruction manual model (DREF.CATProduct) and the inspection and maintenance model (INSP.CATProduct). By appropriately configuring the link in this way, even if the position of the aircraft fuselage panel 1 in the aircraft model is changed, the link function can automatically adjust the position of the locator 21 to match the changed position of the aircraft fuselage panel 1, thereby reducing the design work required to keep up with changes to the aircraft model and the time and effort required for that work.

[0029] The method for updating linked information in the layout model or manufacturing model is arbitrary. For example, the file storing the layout model or manufacturing model may be configured to automatically update the linked data by referencing the linked data when the file storing the layout model or manufacturing model is opened using CAD software. Alternatively, the file storing the layout model or manufacturing model may be configured to reflect changes in the linked data by opening the file using CAD software and performing an operation such as pressing a link update button. By following the links in this way and reflecting changes in the aircraft model in the layout model, the layout model illustrated in FIG. 4C can be automatically obtained. Furthermore, a manufacturing model (not shown) corresponding to FIG. 4C can be automatically obtained. As a result, every time a design model is changed according to a design phase, from initial setup to final drawing, the change can be automatically reflected in the layout model for jig design and the manufacturing model for jig manufacturing.

[0030] Next, the process of generating a BOM from a manufacturing model will be described with reference to FIGS. 7A and 7B. As illustrated in FIG. 7A, the jig configuration model (TOOL.CATProduct) of the manufacturing model includes technical requirements related to manufacturing, such as surface treatment, heat treatment, and welding instructions; technical requirements related to inspection and checkup; production notes, such as tolerance requirements; manufacturing parameters, such as material, size, and weight; and, if the jig components are purchased, information such as the vendor, model number, name, and quantity of the components. When the jig designer performs a predetermined operation, the BOM generation unit 15 extracts information necessary to arrange the components that make up the jig from the jig configuration model data of the manufacturing model, generates a BOM, and outputs it to an electronic file or the like. FIG. 7B shows an example of an output BOM. DET.No is a component identifier, and for each component, list information including the component model number, name, and quantity is output. In addition to a list of components to be ordered, the BOM may also include technical requirements, such as surface roughness specifications, heat treatment conditions, heat treatment hardness, whether surface treatment is required, whether welding is required, and whether material testing and hardness testing are required. The BOM and jig configuration model (including the 3D model of the jig) are handed over to, for example, a jig manufacturer. The jig manufacturer arranges the parts based on the BOM and produces the jig by referring to the jig shape, geometric dimensional tolerances, and production instructions provided by the production model using capture (a method of displaying information such as geometric dimensional tolerances, individual technical requirements, and processing methods in a speech bubble-like format at the target location on the 3D model).

[0031] Next, the process of generating captures from a manufacturing model will be described with reference to FIGS. 7C and 7D. As illustrated in FIG. 7C, Captures 71, including jig-specific processing information such as isometric drawings, individual-item processing drawings with instructions for drilling, surface processing, and welding, and detailed drawings, is registered in the Annotation Set directly under the manufacturing model (DWG.CATProduct). Captures 72, including jig assembly information such as general assembly drawings and sub-assembly drawings, is registered in the Annotation Set directly under the manufacturing model (DWG.CATProduct). This information is registered, for example, by a jig designer. When the jig designer performs a predetermined operation, the capture generation unit 16 generates captures from Captures 71 and 72. For example, the capture generation unit 16 automatically generates captures from the jig configuration model data of the manufacturing model using a dedicated macro or the like. The captures include technical requirements related to manufacturing, technical requirements related to inspection and maintenance, production notes, etc. FIG. 7D(a) shows an example of a capture generated from Captures 71, and FIG. 7D(b) shows an example of a capture generated from Captures 72. In manufacturing sites, various work instructions, such as those for welding and assembly, are required for work efficiency. Typically, work instructions are created separately from the model. This often results in design work time and mismatches with drawings. In contrast, in this embodiment, CAD models of components and other components and work instruction information are defined and managed on a model-based basis. As a result, as illustrated in FIG. 7C, the manufacturing model (DWG.CATProduct) can define various technical instructions for individual and assembled products, including shape, specifications, geometric dimensional tolerances, and processing instructions for welding and surface treatment. This technical information can then be automatically output as captures (e.g., FIG. 7D). Captures can be output in non-CAD formats such as images and PDFs. Captures can also be output not only from the jig configuration model (TOOL.CATProduct), but also from the jig instruction manual model (DREF.CATProduct) and the inspection and inspection model (INSP.CATProduct).Examples of information output as captures include, for jig configuration models, geometric dimensioning and tolerancing (GD&T), additional processing instructions, welding instructions (balloon diagrams), assembly drawing (assembly) instructions, set and inspection dimension instructions, and surface treatment, painting, and stamping instructions. For jig instruction manual models, captures include instructions on parts to be attached and removed, instructions on how to use shared parts, and instruction manuals. For inspection and inspection models, captures include test procedures for load tests and inspection instructions. Using the output captures during procurement and production (assembly) allows for smooth jig arrangement. Furthermore, referencing captures during load tests and quality inspections allows for smooth testing. Similar to BOMs, by linking captures to various models, such as jig configuration models, captures are automatically updated when the aircraft model is changed. In the design process, after design is completed, captures are output at the same time as the BOM, and are used to arrange jigs and distribute them to jig and tool manufacturers. The jig manufacturer arranges for parts based on the BOM and manufactures the jig by referring to the manufacturing instructions provided by the capture.

[0032] This system allows for the generation of manufacturing models and BOMs for advance jig ordering in conjunction with aircraft design, and allows changes to the aircraft model to be quickly reflected in the manufacturing model and BOM. Therefore, jig manufacturing can begin early after the initial design of the aircraft model (or even during the design process), reducing the development lead time for aircraft, including jigs. If drawings are revised during ordering, comparing the old and new BOMs makes it easy to see the addition, specification change, or deletion of parts to be ordered, allowing for a quick review of the order. Furthermore, comparing the old and new captures allows for the prompt confirmation and consideration of changes to the work.

[0033] (operation) Next, the operation of the jig model creating device 10 of this embodiment will be described. FIG. 8 is a flowchart showing an example of the operation of the jig model creating device according to the embodiment. First, a designer creates an aircraft model. The aircraft model acquisition unit 12 acquires the created aircraft model (step S11) and stores the aircraft model in the storage unit 18. Next, a jig designer creates a layout model by link-copying the aircraft model in the storage unit 18 (step S12). For example, the jig designer uses the layout model creation unit 13 (CAD software) to link-copy a portion of the aircraft model related to the target jig and creates a layout model. Based on the operation of the jig designer, the output unit 17 outputs the layout model to a display device or the like. The jig designer refers to the linked-copied aircraft model and designs a jig required to manufacture the aircraft part. The jig designer also sets up related equipment and related jigs required to manufacture the jig, defines reference planes, correction planes, and positional relationships with the aircraft, sets links, etc. When the jig designer designs and sets these items, the layout model creation unit 13 stores the set information in the memory unit 18 as each element (LREF.CATProduct, RLM.CATProduct, TLM.CATProduct) of the tree structure of the layout model described in Figure 5.

[0034] Next, the jig designer creates a manufacturing model by link-copying the layout model in the storage unit 18 (step S13). For example, the jig designer uses the manufacturing model creation unit 14 (CAD software) to link-copy the basic layout model (TLM.CATProduct) of the layout model to create the manufacturing model. The jig designer sets information required for jig manufacturing (e.g., the technical requirements exemplified in FIG. 7A) by referring to the link-copied basic layout model of the jig. The jig designer also sets assembly instructions, inspection and maintenance instructions, etc. for the jig. After the jig designer has made these settings, the manufacturing model creation unit 14 stores the set information in the storage unit 18 as each element (NOTE.CATProduct, TOOL.CATProduct, DREF.CATProduct, INSP.CATProduct) of the tree structure of the layout model described in FIG. 5. Next, when the jig designer performs a predetermined operation, the BOM generation unit 15 extracts the components of the jig from the jig configuration model (TOOL.CATProduct) of the manufacturing model and outputs it as a BOM through the output unit 17 (step S14). In addition, the capture generation unit 16 generates a capture from the jig configuration model (TOOL.CATProduct) and outputs the capture (e.g., FIG. 7D) through the output unit 17 (step S14). The jig designer passes the jig configuration model, BOM, and capture to the jig manufacturer and requests the jig to be manufactured. This allows the jig to be manufactured early. Alternatively, the output unit 17 may automatically send the generated BOM and capture to the jig manufacturer's system, for example. Furthermore, the jig manufacturer's system may be configured to link with an inventory management system and an ordering system, and when the BOM is output from the jig model creation device 10, identify the types and quantities of parts that are out of stock and automatically arrange for the parts to be purchased. Previously, jig manufacturing and inspection required detailed instructions based on paper drawings or 2D drawings. Furthermore, while there were previously complicated instructions for bolts and small components specific to aircraft jigs, in order to simplify jig design and manufacturing work, data management for individual components (bolts, etc.) was not carried out as with aircraft drawings, and BOM creation involved a lot of manual work, such as arranging for parts without preparing a BOM.In contrast, according to this embodiment, by defining jig specifications and technical instructions for large-scale jigs used in aircraft manufacturing on a model-based basis, BOMs and captures can be automatically generated while minimizing increases in design work hours. Since a BOM for jig advance procurement can be generated in conjunction with aircraft design, jig production can be started early, reducing aircraft development lead time. Information related to jig design and production can be managed based on layout models and production models without using paper or 2D drawings, clarifying drawing authority and reducing design work and design data management costs. Automatic BOM generation enables detailed management of jig costs, and by directly procuring necessary parts using the BOM, jig procurement work can be simplified. Furthermore, technical requirements and work instructions required for jig production and testing can be registered and managed in the jig configuration model and output as captures along with the BOM, jig production can be made more efficient.

[0035] Next, it is determined whether there is a change in the aircraft model (step S15). If there is no change (step S15; No), the process proceeds to step S19. If there is a change in the aircraft model (step S15; Yes), the aircraft model acquisition unit 12 acquires the changed aircraft model (step S16). Next, the layout model and the manufacturing model are updated based on the changed aircraft model (step S17). For example, the jig designer reads out the layout model using the layout model creation unit 13 and performs a predetermined operation to reflect the changes in the aircraft model in the layout model. As a result, the changes are reflected in the aircraft model (ENG.CATProduct) of the layout model linked and copied from the aircraft model, the facility information and related jig model (LREF.CATProduct) and related design model (RLM.CATProduct) linked to the aircraft model in the layout model are updated, and the basic layout model (TLM.CATProduct) linked to the related design model is updated. In addition, the jig designer reads out the manufacturing model using the manufacturing model creation unit 14 and performs a predetermined operation to reflect the changes in the layout model in the manufacturing model. This updates the jig configuration model (TOOL.CATProduct) of the manufacturing model that is linked to the basic layout model of the layout model. When the design information, etc. that is affected by the change to the aircraft model is reflected in the manufacturing model, the BOM generation unit 15 regenerates a BOM from the changed manufacturing model and re-outputs the BOM via the output unit 17 (step S18). At this time, the BOM generation unit 15 may automatically generate, in addition to the changed BOM, a comparison table of the old and new BOMs that compares the BOMs before and after the change. Furthermore, the capture generation unit 16 regenerates a capture from the changed manufacturing model and re-outputs the capture via the output unit 17 (step S18). At this time, the capture generation unit 16 may also generate a comparison table of the old and new captures. The jig designer notifies the jig manufacturer of the change to the jig by passing the jig configuration model that reflects the change to the aircraft model, the re-output BOM, and the capture to the jig manufacturer. Alternatively, the output unit 17 may transmit the generated BOM, the comparison table between the new and old BOMs, the capture, and the comparison table between the new and old capture to the system of the jig manufacturer.In this case, too, the comparison table of the old and new BOMs may be linked with the inventory management system and ordering system, so that the cancellation of changed parts and additional orders can be automatically executed. In this way, by updating the shape and specification definitions according to the aircraft design phase and updating the BOM each time, it is possible to manufacture jigs in parallel with jig design. Next, it is determined whether the aircraft design is complete (step S19). If the design is complete (step S19; Yes), the processing of FIG. 8 is terminated. If the design is not complete (step S19; No), the processing from step S15 onwards is repeatedly executed.

[0036] (effect) As described above, the manufacturing model creation method of this embodiment allows jig design and jig manufacturing to be quickly generated in response to changes in the aircraft design. This allows jig design and manufacturing to be performed in conjunction with the aircraft design, thereby reducing the development lead time for aircraft.
