Description

[Technical field]

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

[0002] In the manufacture of aircraft, type certification is carried out based on a design model, which is the design information of the completed aircraft. In the type certification, safety inspections on the design and manufacturing process are carried out, and if the inspections do not pass, design changes are made. The design model is the design information of the completed aircraft, but for manufacturing, drawings and processing instructions for each part that constitutes the aircraft are required, rather than drawings of the completed aircraft. For example, the parts that constitute the aircraft, such as skins and stringers, are manufactured, and the aircraft is completed through multiple assembly processes. In each assembly process, holes are drilled in the parts and the parts are joined with bolts, fasteners, etc. The design model contains information that indicates the position of the holes, but does not contain instruction information such as which assembly process to drill the holes and join them in. In addition, in the assembly process, additional processing that is not related to the completed aircraft is often performed on the parts, and in order to perform the additional processing, processing instructions different from the information contained in the design model are required. In the case of aircraft, parts are assembled while undergoing additional processing such as drilling holes and cutting off excess material and tabs, so the packaging appearance of each part (for example, shape elements such as holes, tabs, excess material, etc.) differs between when completed and when assembled, and separate blueprints for manufacturing parts (called manufacturing models) are required.

[0003] Conventionally, the assembly process was planned based on the design model, and if individual instructions for part manufacturing were required, the required specifications were presented, and when the parts were manufactured, a manufacturing model for the parts was created from the design model based on the requirements. In aircraft development, there are many changes to the design model, so creating a manufacturing model requires a lot of effort and time. In addition, a method of adding and managing part manufacturing instruction information to the design model is also possible, but with this method, there are issues such as the amount of information in the design model becoming huge, which makes processing using the design model heavy and may interfere with design work in the development phase.

[0004] Patent Document 1 discloses a system that outputs a graphical view that supports machining and fastening operations of parts that constitute an aircraft. However, the technology of Patent Document 1 is not a technology for creating a graphical view from a design model. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2015-79506 A Summary of the Invention [Problem to be solved by the invention]

[0009] The manufacturing model creation method according to the present disclosure includes the steps of creating a plan model based on a design model, which is design information for a finished product manufactured by assembling a plurality of parts, in which manufacturing instruction information required for assembling the parts is set for each of the parts, and extracting part information for the parts to be manufactured from the design model, and adding the instruction information for the parts to be manufactured extracted from the plan model to the extracted part information, thereby creating a manufacturing model including manufacturing instructions for the parts to be manufactured.

[0010] The program of the present disclosure causes a computer to execute the steps of: creating a plan model based on a design model, which is design information of a finished product manufactured by assembling multiple parts, in which manufacturing instruction information required for assembling the parts is set for each of the parts; and extracting part information of the parts to be manufactured from the design model, and adding the instruction information of the parts to be manufactured extracted from the plan model to the extracted part information, to create a manufacturing model including manufacturing instructions for the parts to be manufactured.

[0013] <Embodiment> Hereinafter, a method for creating a manufacturing model according to the present disclosure will be described with reference to FIGS. (composition) FIG. 1 is a block diagram showing an example of a manufacturing model creating device according to an embodiment. The manufacturing model creation device 10 is composed of one or more computers. As shown in the figure, the manufacturing model creation device 10 includes an input receiving unit 11, a design model creation unit 12, a plan model creation unit 13, a manufacturing model creation unit 14, an output unit 15, and a storage unit 16.

[0014] The input receiving unit 11 receives various information input using input devices such as a keyboard, mouse, touch panel, buttons, etc., instruction information instructing the start and end of processing, etc. For example, the input receiving unit 11 receives manufacturing information input to the manufacturing model creation device 10, such as assembly instructions for positioning by shims and sealing, drilling, riveting, and fastening, surface treatment, painting, tabs, excess pad, etc. for each part of an aircraft. A tab is a handle used when carrying a part, and excess pad is an area for adjustment that is manufactured slightly larger than the size specified in the design model. The tab and excess pad are eventually cut off.

[0015] The design model creation unit 12 creates a design model that shows the aircraft's packaged appearance after final assembly. The design model includes 3D model information that shows the aircraft's shape when completed, as well as assembly information such as fastener and bolt connection information, and positioning information using shims and sealants. The design model is divided into assembly process units and managed.

[0016] The plan model creation unit 13 creates a plan model for the assembly of parts and adds it to the design model. The plan model is information in which the drilling instructions are organized for each part from the assembly information of the design model, and further, manufacturing information such as tabs, excess padding, surface treatment, and painting instructions are organized and created for each assembly process. Manufacturing information is not included in the design model because it is not necessary for the finished product, but is information required when manufacturing and assembling parts. In addition, the design model may specify information on the position and vector of the hole (from which direction the hole should be drilled), but in order to actually drill a hole, it is necessary to consider the assembly procedure of the parts, etc., and then decide the details on which assembly process is appropriate to drill the hole, whether to drill the hole when part A and part B are combined, or whether to drill the hole alone, and so on. It is not possible to actually manufacture with only the combination information included in the assembly information of the design model. The plan model includes information in which the position and vector information of the hole to be drilled in each assembly process is organized for each part. The plan model is considered and organized by the assembly staff for each assembly process, that is, for each assembly unit. An assembly is a collection of one or more parts. For example, the fuselage of an aircraft is composed of multiple barrels, and each barrel is composed of multiple panels. For example, FIG. 2 shows an example in which one panel is treated as one assembly. As shown in FIG. 2, a panel 20 is composed of a skin 21, a stringer 22, a shear tie 23, a stringer clip 24, and the like, and manufacturing information such as drilling instructions for these parts needs to be considered in a state where they are combined as the panel 20. The assembly staff considers the details of drilling and the necessity of additional processing such as excess material for each assembly. The assembly staff inputs the results of the consideration into the manufacturing model creation device 10 as a plan model. The plan model creation unit 13 creates data in which the design model is link-copied, and adds the input plan model to the created data. Data in which the design model is link-copied and the plan model is added is called a 3D model for assembly plan for convenience. The link copy is, for example, a function provided in CAD software, and when the name or position of an element A (e.g., a bolt) with assembly information is changed in the design model, the change is automatically reflected in the element A of the link copy destination data.By utilizing this function, when the design model is changed, the contents of the change can be automatically reflected in the 3D model for assembly plan. The link copy function is not limited to the function 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 design model are associated with each other and managed, and a change in element A in the design model is used as a trigger to reflect the change made to the design model in element A of the link copy destination data having the corresponding identification number. The plan model and the 3D model for assembly plan are created when an assembly technician designs an assembly process, and are used when the assembly process is carried out.

[0017] The manufacturing model creation unit 14 extracts information on the parts to be manufactured from the design model and the plan model, copies the information without linking, and adds manufacturing information such as drilling instructions for the parts extracted from the plan model to the part information (part name, size, coordinate information, etc.) extracted from the design model to create a manufacturing model. The manufacturing model creation unit 14 creates data by copying the design model without linking, and adds a plan model and a manufacturing model to the created data. Data by adding a manufacturing model, etc. to data by copying the design model without linking is called a manufacturing 3D model for convenience. For example, in the example of FIG. 2, a manufacturing model and a manufacturing 3D model for the skin 21, a manufacturing model, etc. for the stringer 22, a manufacturing model, etc. for the shear tie 23, and a manufacturing model, etc. for the stringer clip 24 are created. Each manufacturing model, etc. is handed over to the person in charge of manufacturing each part and used for manufacturing.

[0018] The design model creation unit 12, the plan model creation unit 13, and the manufacturing model creation unit 14 are configured to include, for example, CAD software. FIG. 2 shows an overview of the design model, the plan model, and the manufacturing model. When the design model is displayed using CAD software or the like, only the packaging form in which the skin 21, the stringer 22, the shear tie 23, and the stringer clip 24 are assembled is displayed as a 3D model. In contrast, the 3D model for assembly plan displays manufacturing information such as hole drilling instruction information (X marks in FIG. 2; only some of the X marks are marked with reference numerals 27 to avoid complication) required for assembling the parts, tabs 25, and excess pads 26. In addition, the 3D model for manufacturing displays the packaging form of each part and manufacturing information derived from the plan model. Note that the tabs 25 and excess pads 26 of the skin 21 are components required during assembly, and are ultimately cut off and do not exist in the finished product. The difference in the shape of the parts between the finished product and the time of assembly / manufacturing is called a different packaging form. According to the method of creating a manufacturing model of this embodiment, it is possible to create a manufacturing model that includes manufacturing and processing instructions for each assembly process, for example, by instructing the creation of tab 25 in an early assembly process and instructing the cutting of tab 25 in a later process. This is effective for products such as aircraft, in which the packaging of parts differs between the finished product and when assembled or manufactured.

[0019] The output unit 15 outputs the design model, the plan model, and the manufacturing model to a display device, an electronic file, or the like. The storage unit 16 stores a design model, a plan model, a manufacturing model, and the like.

[0020] Figure 3 shows an overview of the manufacturing model creation process. First, a design model is created. The design model includes part models for each part (part type, size, etc.), assembly models (what parts the assembly is made up of), assembly information (part fastening information, sealant information, shim information), and reference standards (for example, a reference surface in three-dimensional space on which panel 20, as shown in Figure 2, is placed; a barrel is created by placing panels along this reference surface), organized by assembly process (assembly unit). The design model is used for type certification, etc. Once the design model is created, a plan model is created without waiting for the completion of type certification, etc.

[0021] The plan model includes manufacturing information such as reference hole information, drilling instruction information (hole position, size, drilling direction, etc.), tab information (where and what shape of tab to make), padding information (where and what shape of pad to make), surface treatment and painting information (surface treatment method and type of painting). The plan model is created for each assembly process by a knowledgeable assembly technician who considers what procedure to assemble and which assembly process requires processing in order to realize the packaging style and assembly information shown in the design model. More specifically, the drilling instructions are organized for each target part by link-copying the necessary elements (hole position point, vector indicating the direction to drill the hole) from the assembly information of the design model. The hole diameter, penetration, etc. are set for the target part by referring to the shape set name and parameters of the assembly information. Tab, padding, surface treatment and painting instructions are created by referring to the necessary elements (surface, contour, etc.) from the design model. For example, the shape (packaging style) is specified according to the part by setting appropriate values ​​for each parameter of the parametric model. When design changes are made, elements of the plan model are automatically updated by link copy. When a plan model is created, a manufacturing model is created from the design model and the plan model.

[0022] Manufacturing models are generated part by part, and include an assembly model (which assembly the part composes), part model (type and size of the part), and manufacturing information (additional processing to be performed on the part, etc.). All of this information has been extracted from the design model or plan model by referencing names (for example, names of parts such as skin, stringer, etc.) and numbers. Manufacturing models are displayed in a format where the relevant elements of the plan model have been added to the assembly information tree of the design model of the part (Fig. 7). Whenever a design change is made to the design model, a manufacturing model is generated from the new design model and plan model.

[0023] An example of a design model is shown in Figure 4. The example shown in Figure 4 is a schematic display example when a design model of a panel in the fuselage of an aircraft is displayed using the functions of CAD software. As shown in the figure, only a 3D model 401 of the panel when completed and tree information 402 are displayed. Assembly information is displayed in the tree information 402.

[0024] An example of a design model is shown in 501 of FIG. 5A. 501 of FIG. 5A shows an assembly model of a panel and assembly information related to drilling. In the tree information 402 of FIG. 4, for example, information as shown in 501 of FIG. 5 is displayed. As shown in the figure, the panel includes Panel Assy1 and Panel Assy2. Panel Assy1 includes Skin1, Shear-tie1_1 to 1_n, Stringer Assy1_1 to 1_n, etc. Similarly, Panel Assy2 includes Skin2, Shear-tie2_1 to 2_n, Stringer Assy2_1 to 2_n, etc. As assembly information for connecting Panel Assy1 and Panel Assy2, Fastener1 is defined, and hole position information Point1_1 for Fastener1 is defined. In addition, Fastener2 to 3 and hole position information Point2_1, 3_1, etc. are defined as assembly information of Panel1.

[0025] An example of a plan model is shown in 502 of FIG. 5A. The plan model is created by manually link-copying the assembly information of the design model. In the example of FIG. 5A, for example, Points 1_1 to 1_i of the design model are organized as a hole to be drilled in Skin1, "Skin1 Hole #30". Also, Points 2_1 to 2_j and Points 3_1 to 3_k of the design model are organized as a hole to be drilled in Skin1, "Skin1 K / H #30". K / H means an important hole used for positioning. In the example of FIG. 5A, only the position information of the hole is described as a drilling instruction, but in reality, vector information indicating the direction of drilling the hole is included.

[0026] An example of a manufacturing model is shown in 503 of Fig. 5A. In the manufacturing model, part information including the name of the target part is extracted from the design model and the plan model based on the name of the target part, etc. For example, when Skin1 is specified as the target part, the part model Skin1 is extracted from the design model, and drilling instruction information including "Skin1" in the name (for example, the above-mentioned "Skin1 Hole#30") is extracted from the plan model.

[0027] Figure 5B shows examples of instructions for tabs, padding, surface treatment, and painting. The design model includes various design criteria (reference outer surface, skin contour surface, stringer reference surface, frame reference surface), Skin1, Shear-tie1_1~1_n, Stringer Assy1_1~1_n, and assembly information for Panel Assy1. When setting manufacturing information such as tabs and padding in the plan model, the design model is linked and copied, and for example, for Skin1, an item called Skin1 tab is created and the position and shape of the tab are set. A reference standard can be used to set the shape of the tab, etc. Similarly, an item called Skin1 padding is created and the position and shape of the padding are set, and an item called Skin1 surface treatment / painting is created and instructions for surface treatment and painting are set. The manufacturing model for Skin1 is created by extracting part information such as part name from the design model, and by extracting manufacturing information such as tabs, padding, surface treatment, and painting from the plan model. Note that, although an example of drilling instructions is shown in FIG. 5A and examples of tabs, excess pads, etc. are shown in FIG. 5B, in reality, these are not separate. For example, the manufacturing model of Skin1 includes both the drilling instructions shown in FIG. 5A and the manufacturing information shown in FIG. 5B.

[0028] FIG. 6 shows an example of a three-dimensional model for an assembly plan. FIG. 6 shows a schematic display example when data in which a plan model is added to the design model in FIG. 4 is displayed using a function of CAD software. As shown in the figure, padding 602, drilling instruction information 603 (marked with an x, with a reference symbol 603 only partially attached), etc. are added to a three-dimensional model 601 of a panel, and in tree information 604 in which assembly information, etc. are displayed, a plan model 606 (e.g., 502 in FIG. 5A) is added in addition to assembly information 605 of the design model (e.g., 501 in FIG. 5A). The plan model 606 includes various design criteria such as drilling instruction information, information such as the shape of padding 602, information such as the shape of a tab if there is one, instruction information for painting and surface treatment, non-standard surface information, and skin contour surface information.

[0029] An example of a 3D model for manufacturing is shown in Fig. 7. Fig. 7 shows a schematic display example of a manufacturing model created from the design model in Fig. 4 and the plan model in Fig. 6, when displayed using a function of CAD software. As shown in the figure, in addition to assembly information 605 (e.g., 501 in Fig. 5A) of the design model and a plan model 606 (e.g., 502 in Fig. 5A), a manufacturing model 607 (e.g., 503 in Fig. 5A) of the target part is added to the tree information 604'. The manufacturing model 607 includes drilling instruction information, excess pad shape information, tab shape information, painting instruction information, surface treatment instruction information, non-reference surface information, skin contour surface information, stringer reference surface information, frame reference surface information, and the like, related to the target part.

[0030] (operation) Next, the operation of the manufacturing model creating device 10 of this embodiment will be described. FIG. 8 is a flowchart showing an example of the operation of the manufacturing model creating device according to the embodiment. First, a designer creates a design model using the design model creation unit 12 (CAD software) (step S11). The design model creation unit 12 stores the created design model in the storage unit 16. The design models are divided for each assembly process. Next, an assembler links and copies the design model in the storage unit 16 (step S12). When the assembler performs a predetermined operation, the output unit 15 outputs the linked and copied design model to a display device or the like. The assembler refers to the linked and copied design model to design an assembly procedure and drilling, painting, tab processing, and the like required for each assembly process. The assembler classifies manufacturing information such as drilling, painting, and tabs for each assembly process and for each part to be assembled in the assembly process, and creates a plan model (step S13). As illustrated in FIG. 5A and FIG. 5B, the plan model is organized for each part and for each manufacturing information, and is given a name including, for example, the part name and manufacturing name (Hole, K / H, tab, excess material, and the like). For example, in the case of a plan model instructing to drill a hole in Skin1, a name such as "Skin1 Hole #30" is given as in the example of FIG. 5A. Then, manufacturing information such as a specific hole drilling position and a tab shape is set under the name. The person in charge of assembly inputs the created plan model to the manufacturing model creation device 10. The input receiving unit 11 acquires the input plan model and outputs it to the plan model creation unit 13. The plan model creation unit 13 saves the plan model in the storage unit 16. In addition, the plan model creation unit 13 adds the plan model to the link-copied design model and creates a three-dimensional model for assembly plan. The output unit 15 outputs the three-dimensional model for assembly plan to a display device or the like. When the plan model is added, the plan model is added to the tree information 604 as exemplified in FIG. 6, and the contents of the plan model are reflected in the three-dimensional model 601 (such as the extra pad 602 and the hole drilling instruction information 603 in FIG. 6). Next, the person in charge instructs the creation of a manufacturing model. When manufacturing the skin 21, the person in charge inputs, for example, Skin 1 as a part to be manufactured into the manufacturing model creation device 10. The input receiving unit 11 acquires the input part name and outputs it to the manufacturing model creation unit 14. The manufacturing model creation unit 14 refers to the design model in the storage unit 16 and extracts a part model having the same name as the specified part name.The manufacturing model creation unit 14 also refers to the plan model in the storage unit 16 and extracts a plan model whose name includes the specified part name. The manufacturing model creation unit 14 creates a manufacturing model by combining the information extracted from the design model and the plan model (step S14). For example, the manufacturing model creation unit 14 may create data in a tree structure in which the name of the part to be manufactured is used as the root, the name of the plan model is set for each node, and specific manufacturing information is set for the leaves under each node. The manufacturing model creation unit 14 also creates a 3D model for manufacturing by copying the design model without links and adding a plan model and a manufacturing model to the design model copied without links. The output unit 15 outputs the 3D model for assembly plan to a display device or the like (FIG. 7). The manufacturing staff can manufacture the parts they are in charge of by referring to the 3D model for assembly plan. Note that the manufacturing of the parts may be requested to an external supplier. In such a case, a file is created by extracting only the information necessary for manufacturing the parts from the created 3D model for manufacturing, and the created file is passed to the supplier. This makes it possible to request the manufacturing of the parts without passing on unnecessary information.

[0031] (effect) As described above, according to the method for creating a manufacturing model of this embodiment, a manufacturing model including design drawings and processing instructions for parts constituting a product can be efficiently created from a design model, which is design information for a completed product. By adding technical instruction information to be produced in the manufacturing and assembly of parts to a 3D CAD model (design model), technical instruction information for assembly and part manufacturing can be centrally managed (for example, Figs. 6 and 7). This reduces duplicate work such as creating new drawings for manufacturing from the design model in the manufacturing preparation stage, and prevents mismatching with the design model. In addition, by considering an assembly plan before creating a manufacturing model and creating it as a plan model, it is possible to create an efficient assembly plan and issue manufacturing instructions for parts without errors. In addition, with regard to the method for adding manufacturing information to a design model, according to this embodiment, by separating design information and manufacturing information, it is possible to create an assembly plan and create a manufacturing model to which manufacturing information is added without interfering with design work in the development phase. In addition, when creating a plan model, the plan model is created using data linked and copied from the design model, so even if a change occurs in the design model, the change can be quickly reflected in the linked data, and the plan model can be changed or modified as necessary. In addition, with regard to the manufacturing model, data on the parts to be manufactured is extracted from the design model and plan model without the need to copy links each time. This means that even if there are design changes, by checking the changed design model and plan model before creating the manufacturing model, changes to the design model are automatically reflected in the manufacturing model, preventing situations that could cause confusion in the manufacturing department. Conventionally, assembly planning was performed after the design model was released, manufacturing information was organized, and the information was transmitted to the manufacturing staff in another format such as paper. In contrast, according to the present embodiment, the work can be brought forward, and a plan model can be created and confirmed in advance using the preceding data of the design model in the layout stage. This makes it possible to improve the quality of drawings before the design model is released. Furthermore, by updating the plan model after the design model is released and automatically generating a manufacturing model, it is possible to obtain effects such as unifying data (unifying the design model, plan model, and manufacturing model), reducing man-hours, and preventing drawing errors. Since the plan model can be automatically updated by utilizing link copies from the design model, changes from the design model in the layout stage can be quickly reflected in the plan model, and the manufacturing lead time after the official manufacturing model is released can be shortened.

[0036] (1) A manufacturing model creation device according to a first aspect has: a means for creating a plan model based on a design model, which is design information of a finished product manufactured by assembling a plurality of parts, in which manufacturing instruction information required for assembling the parts is set for each of the parts; and a means for extracting part information of the parts to be manufactured from the design model, and adding the instruction information of the parts to be manufactured extracted from the plan model to the extracted part information, to create a manufacturing model including manufacturing instructions for the parts to be manufactured. This makes it possible to efficiently create a manufacturing model, including design drawings and processing instructions for the parts that make up the product, from a design model, which is the design information for the completed product.

[0037] (2) A manufacturing model creation device according to a second aspect is a manufacturing model creation device according to (1), wherein the means for creating the plan model creates and displays a 3D model for an assembly plan by adding the plan model to a 3D CAD model of the completed body. This allows the 3D model for assembly plans to which plan models have been added to be referenced without modifying the 3D CAD model of the design model, making it possible to centrally manage design information and assembly instruction information.

[0038] (3) A manufacturing model creation device according to a third aspect is a manufacturing model creation device according to (1) to (2), wherein the means for creating the manufacturing model creates and displays a 3D model for manufacturing by adding the manufacturing model to a 3D CAD model of the completed body. This allows the 3D model for manufacturing to be referenced while leaving the 3D CAD model of the design model untouched, making it possible to centrally manage design information and instruction information for part manufacturing.

[0039] (4) A manufacturing model creation device according to a fourth aspect is the manufacturing model creation device according to (1) to (3), in which the plan model is created for each assembly process of the product. The manufacturing information for parts needs to be considered when the parts are assembled. Therefore, by creating a plan model for each assembly step of the product, it is possible to provide manufacturing information without errors.

[0040] (5) A manufacturing model creation device according to a fifth aspect is a manufacturing model creation device according to any one of (1) to (4), wherein the instruction information includes information instructing processing for drilling holes, excess material, and handles for carrying the part. This allows for the drilling, padding and tab manufacturing required for part assembly.

[0041] (6) A manufacturing model creation device according to a sixth aspect is a manufacturing model creation device according to any one of (1) to (5), wherein the means for creating the plan model copies the design model in such a manner that, when a change is made to the design model, the change is also reflected in the data to which the design model is copied, and creates the plan model based on the copied design model. This allows any design changes (changes to the design model) to be quickly reflected in the design model that is the link copy destination on the plan model side. By quickly making changes to the plan model in response to design changes, the plan model can be managed to be in a state that corresponds to the latest design model. In addition, because the design model is updated automatically, it is possible to eliminate the step of reflecting the changes in the link copy destination.

[0042] (7) A manufacturing model creation method according to a seventh aspect includes the steps of: creating a plan model based on a design model, which is design information of a finished product manufactured by assembling a plurality of parts, in which manufacturing instruction information required for assembling the parts is set for each of the parts; extracting part information of the parts to be manufactured from the design model, and adding the instruction information of the parts to be manufactured extracted from the plan model to the extracted part information, thereby creating a manufacturing model including manufacturing instructions for the parts to be manufactured.

[0043] (8) A program according to an eighth aspect causes a computer to execute the steps of: creating a plan model based on a design model, which is design information of a finished product manufactured by assembling a plurality of parts, in which manufacturing instruction information required for assembling the parts is set for each of the parts; extracting part information of the parts to be manufactured from the design model, and adding the instruction information of the parts to be manufactured extracted from the plan model to the extracted part information, thereby creating a manufacturing model including manufacturing instructions for the parts to be manufactured.
