Description

Technical Field

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

Background Art

[0002] In aircraft manufacturing, type certification is carried out based on a design model, which is design information of the completed aircraft. In type certification, safety inspections related to the design and manufacturing processes are conducted, and if the inspections are not passed, design changes and the like occur. The design model is design information of the completed aircraft, but for manufacturing, instead of the drawings of the completed aircraft, drawings of each component constituting the aircraft and processing instructions are required. For example, components such as skins and stringers that make up the airframe are manufactured, and the aircraft is completed through multiple assembly processes. In each assembly process, holes are drilled in the components and the components are joined by bolts, fasteners, etc. Although the design model includes information indicating the positions of the holes, it does not include specific instruction information on which assembly process to drill the holes and perform the joining. Also, in the assembly process, additional processing that is not related to the completed airframe is often performed on the components. To perform the additional processing, processing instructions different from the information included in the design model are required. In the case of an aircraft, since assembly is performed while performing additional processing such as drilling holes, removing surplus material, and cutting tabs on the components, the loading posture of the individual components (for example, shape elements such as holes, tabs, and surplus material) is different between the time of completion and the time of assembly, and a design drawing for component manufacturing (referred to as a manufacturing model) is separately required.

[0003] Conventionally, based on the design model, planning work for the assembly process is carried out. When individual instructions for component manufacturing are required, the requirements specifications are presented. During component manufacturing, a manufacturing model of the component is created from the design model based on those requirements. In aircraft development, design model changes are sometimes frequent, and a great deal of labor and time are spent on creating the manufacturing model. Also, a method of adding and managing instruction information for component manufacturing to the design model is conceivable, but in this method, the amount of information in the design model becomes enormous, the processing using the design model becomes heavy, and there is a problem that it may interfere with the design work in the development phase.

[0004] Patent Document 1 discloses a system that outputs a graphical view to assist in the machining and fastening of aircraft components. However, the technology described in Patent Document 1 is not a technology for creating a graphical view from a design model. [Prior art documents] [Patent Documents]

MODE FOR CARRYING OUT THE INVENTION

[0013] <Embodiment> Hereinafter, a method for creating a manufacturing model of the present disclosure will be described with reference to FIGS. 1 to 9. (Configuration) FIG. 1 is a block diagram showing an example of a manufacturing model creation device according to the 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 reception 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 reception unit 11 receives various types of information input using input devices such as a keyboard, mouse, touch panel, buttons, etc., and instruction information for instructing the start and end of processing. For example, the input reception unit 11 receives assembly instructions such as positioning by shims and seals, drilling, riveting / fastening, surface treatment / painting, tabs / excess material, etc. for each part of the aircraft input to the manufacturing model creation device 10. A tab is a handle used when carrying parts, and excess material is an adjustment area manufactured slightly larger than the size specified in the design model. Tabs and excess material are finally cut.

[0015] The design model creation unit 12 creates a design model that shows the aircraft's packaging configuration after final assembly. The design model includes 3D model information showing the aircraft's completed shape, as well as assembly information such as connection information for fasteners and bolts, and positioning information using shims and sealants. The design model is also managed in sections based on the assembly process.

[0016] The plan model creation unit 13 creates a plan model for the assembly of parts and adds it to the design model. A plan model is information created by organizing drilling instructions for each part from the assembly information of the design model, and further organizing and creating manufacturing information such as tabs, excess material, surface treatment, and painting instructions for each assembly process. Manufacturing information is not included in the design model because it is not necessary for the finished product, but it is information that is necessary when manufacturing and assembling parts. In addition, although the design model may specify hole position and vector (from which direction to drill the hole) information, in order to actually drill the hole, it is necessary to consider the assembly procedure of the parts and other factors to determine which assembly process is appropriate for drilling the hole, whether to drill the hole when parts A and B are combined, or drill the hole in a single part, and then decide on the details. Actual manufacturing cannot be done with only the combination information included in the assembly information of the design model. The plan model includes information that organizes the hole position and vector information to be drilled in each assembly process for each part. The plan model is reviewed and organized by the assembly person at the assembly process unit, that is, at the assembly unit of the assembly. 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. Figure 2 shows an example where one panel is treated as one assembly. As illustrated in Figure 2, panel 20 is composed of skin 21, stringers 22, shear ties 23, stringer clips 24, etc., and manufacturing information such as drilling instructions for these parts must be considered when they are assembled as panel 20. The assembly person considers the details of drilling, whether additional processing such as excess material is necessary, etc., on an assembly basis. The assembly person inputs the results of the consideration as a plan model into the manufacturing model creation device 10. The plan model creation unit 13 creates data by link-copying the design model and adds the inputted plan model to the created data. The data with the plan model added to the data by link-copying the design model is conveniently called a 3D model for assembly plans. Link-copying is a function provided by CAD software, for example, in which, if the name or position of an element A (e.g., a bolt) with assembly information is changed in the design model, the changes are automatically reflected in element A of the linked copy data.By utilizing this function, changes to the design model can be automatically reflected in the 3D model for the assembly plan. The linked copy function is not limited to the functions of CAD software. For example, the identification number of element A in the linked copy destination data and the identification number of element A in the source design model can be associated and managed, and a function can be implemented that, triggered by a change in element A of the design model, reflects the changes made to the design model in element A of the linked copy destination data that has the corresponding identification number. Plan models and 3D models for assembly plans are created when assembly personnel design the assembly process and are used when the assembly process is carried out.

[0017] The manufacturing model creation unit 14 extracts information about the parts to be manufactured from the design model and plan model, copies them 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 the plan model and manufacturing model to the created data. The data created by adding the manufacturing model, etc. to the data copied from the design model without linking is conveniently called a 3D model for manufacturing. For example, in the example in Figure 2, a manufacturing model and 3D model for manufacturing of the skin 21, a manufacturing model for the stringer 22, a manufacturing model for the shear tie 23, and a manufacturing model for the stringer clip 24 are created. Each manufacturing model is given 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 composed of, for example, CAD software. Figure 2 shows an overview of the design model, plan model, and manufacturing model. When the design model is displayed using CAD software, only the assembled packaging of the skin 21, stringer 22, shear tie 23, and stringer clip 24 is displayed as a 3D model. In contrast, the 3D model for assembly plans displays drilling instruction information necessary for assembling the parts (marked with an "x" in Figure 2; for simplicity, only some of the "x" marks are labeled with the symbol 27), as well as manufacturing information such as tabs 25 and excess material 26. The 3D model for manufacturing displays the packaging of each part and manufacturing information derived from the plan model. Note that the tabs 25 and excess material 26 of the skin 21 are components necessary during assembly, but are ultimately cut off and do not exist in the finished product. This difference in the shape of the parts between the finished product and the assembled / manufactured product is called a different packaging. According to the manufacturing model creation method of this embodiment, for example, it is possible to create a manufacturing model that includes manufacturing and processing instructions for each assembly process, such as instructing the creation of tabs 25 in the initial assembly process and instructing the cutting of tabs 25 in a later process. This is effective for products such as aircraft, where the packaging of parts differs between the finished product and the assembly / manufacturing stage.

[0019] The output unit 15 outputs the design model, plan model, and manufacturing model to a display device, electronic file, etc. The memory unit 16 stores design models, plan models, manufacturing models, etc.

[0020] Figure 3 shows an overview of the manufacturing model creation process. First, a design model is created. The design model includes component models for each part (type of part, size, etc.), assembly models (what parts make up the assembly), assembly information (fastening information for parts, sealant information, shim information), and reference standards (for example, a reference plane in three-dimensional space on which panel 20, as exemplified in Figure 2, is placed; by placing panels along this reference plane, one barrel is formed), all organized on an assembly process basis (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 location, size, drilling direction, etc.), tab information (where and what shape of tab to create), excess material information (where and what shape of excess material to create), and surface treatment / painting information (surface treatment method and type of paint to be applied). The plan model is created by an experienced assembly person who considers what assembly procedures will be followed and which assembly processes will require processing in order to realize the packaging and assembly information shown in the design model, and is created for each assembly process. More specifically, drilling instructions are created by linking and copying the necessary elements (points indicating hole locations, vectors indicating drilling direction) from the assembly information of the design model and organizing them for each target part. The hole diameter, through-hole, etc. are set for the target part by referring to the shape set name and parameters of the assembly information. Tab, excess material, and surface treatment / painting instructions are created by referring to the necessary elements (faces, contours, etc.) from the design model. For example, the shape (packaging) is specified according to the part by setting appropriate values ​​for each parameter of the parametric model. When design changes occur, the elements of the plan model are automatically updated via linked copying. Once the plan model is created, the manufacturing model is created from the design model and the plan model.

[0022] The manufacturing model is generated on a component basis and includes an assembly model (which assembly the component belongs to), a component model (the type and size of the component), and manufacturing information (such as additional processing to be performed on the component). All of this information is extracted from the design model or plan model by referring to names (e.g., names of components such as skin and stringer) and numbers. The manufacturing model is displayed in a format in which the corresponding elements of the plan model are added to the assembly information tree of the design model of the component (Figure 7). When the design model is modified, a manufacturing model is generated each time from the new design model and plan model.

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

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

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

[0026] Figure 5A, section 503, shows an example of a manufacturing model. Based on the name of the target part, the manufacturing model extracts part information, including the name of the target part, from the design model and the plan model. For example, if Skin1 is specified as the target part, the part model Skin1 is extracted from the design model, and drilling instruction information containing "Skin1" in its name (for example, "Skin1 Hole#30" as described above) is extracted from the plan model.

[0027] Figure 5B shows an example of tab, excess material, surface treatment, and painting instructions. The design model includes various design criteria (out-of-reference 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 excess material in the plan model, the design model is linked and copied. For example, for Skin1, an item called Skin1 Tab is created to set the position and shape of the tab. Reference criteria can be used to set the shape of tabs, etc. Similarly, an item called Skin1 Excess Material is created to set the position and shape of the excess material, and an item called Skin1 Surface Treatment / Painting is created to set instructions for surface treatment and painting. The manufacturing model for Skin1 is created by extracting part information such as part name from the design model and manufacturing information such as tabs, excess material, surface treatment, and painting from the plan model. Although Figure 5A shows an example of drilling instructions and Figure 5B shows examples of tabs, excess material, etc., in reality these are not separate. For example, the manufacturing model for Skin1 includes both the drilling instructions exemplified in Figure 5A and the manufacturing information exemplified in Figure 5B.

[0028] Figure 6 shows an example of a 3D model for assembly planning. Figure 6 illustrates a schematic display of data obtained by adding a plan model to the design model in Figure 4, using the functions of CAD software. As shown in the figure, the 3D model 601 of the panel has added excess material 602, drilling instruction information 603 (marked with an "x", with the code 603 attached to only some parts), etc. In the tree information 604 where assembly information etc. is displayed, in addition to the assembly information 605 of the design model (for example, 501 in Figure 5A), the plan model 606 (for example, 502 in Figure 5A) has also been added. The plan model 606 includes various design criteria such as drilling instruction information, information on the shape of excess material 602, information on the shape of tabs if there are tabs, instruction information for painting and surface treatment, off-standard surface information, and skin contour information.

[0029] Figure 7 shows an example of a 3D model for manufacturing. Figure 7 illustrates a schematic display of a manufacturing model created from the design model in Figure 4 and the plan model in Figure 6, using the functions of CAD software. As shown in the figure, the tree information 604' includes the assembly information 605 of the design model (e.g., 501 in Figure 5A) and the plan model 606 (e.g., 502 in Figure 5A), as well as the manufacturing model 607 of the target part (e.g., 503 in Figure 5A). The manufacturing model 607 includes drilling instruction information, excess material shape information, tab shape information, painting instruction information, surface treatment instruction information, off-reference surface information, skin contour information, stringer reference surface information, frame reference surface information, etc., related to the target part.

[0030] (operation) Next, the operation of the manufacturing model creation apparatus 10 of this embodiment will be described. Figure 8 is a flowchart showing an example of the operation of the manufacturing model creation apparatus according to the embodiment. First, the designer creates a design model using the design model creation unit 12 (CAD software) (step S11). The design model creation unit 12 saves the created design model to the storage unit 16. The design model is divided by assembly process. Next, the assembly person links and copies the design model from the storage unit 16 (step S12). When the assembly person performs a predetermined operation, the output unit 15 outputs the linked and copied design model to a display device or the like. The assembly person refers to the linked and copied design model and designs the assembly procedure and the necessary drilling, painting, tab processing, etc. for each assembly process. The assembly person sorts the manufacturing information such as drilling, painting, tabs, etc. for each assembly process and for each part to be assembled in that assembly process, and creates a plan model (step S13). As illustrated in Figures 5A and 5B, the plan model is organized by part and by manufacturing information, and is given a name that includes, for example, the part name and manufacturing name (Hole, K / H, Tab, Excess Material, etc.). For example, in the case of a plan model that instructs to drill a hole in Skin1, it will be given a name such as "Skin1 Hole#30" as shown in the example in Figure 5A. Under that name, specific manufacturing information such as the drilling location and tab shape is set. The assembly person inputs the created plan model into the manufacturing model creation device 10. The input reception 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 to the storage unit 16. The plan model creation unit 13 also adds the plan model to the linked design model and creates a 3D model for the assembly plan. The output unit 15 outputs the 3D model for the assembly plan to a display device or the like. When the plan model is added, as illustrated in Figure 6, the plan model is added to the tree information 604, and the contents of the plan model are reflected in the 3D model 601 (excess material 602, drilling instruction information 603, etc. in Figure 6). Next, the person in charge instructs the creation of the manufacturing model. When manufacturing Skin 21, the person in charge inputs Skin 1, for example, as the part to be manufactured, into the manufacturing model creation device 10. The input reception unit 11 obtains 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 the part model that has the same name as the specified part name.Furthermore, the manufacturing model creation unit 14 refers to the plan models in the storage unit 16 and extracts plan models that include the specified part name in their name. The manufacturing model creation unit 14 combines the information extracted from the design model and the plan models to create a manufacturing model (step S14). For example, the manufacturing model creation unit 14 may create a tree structure data where the name of the part to be manufactured is 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. Alternatively, the manufacturing model creation unit 14 copies the design model without links, and adds the plan model and manufacturing model to the copied design model to create a 3D model for manufacturing. The output unit 15 outputs the 3D model for assembly plans to a display device or the like (Figure 7). Manufacturing personnel can manufacture the parts they are responsible for by referring to the 3D model for assembly plans. Note that the manufacturing of parts may be outsourced to external suppliers. In such cases, a file is created that extracts only the information necessary for manufacturing the parts from the created 3D model for manufacturing, and this file is provided to the supplier. This allows for the request for manufacturing of parts without providing unnecessary information.

[0031] (effect) As described above, the manufacturing model creation method of this embodiment allows for the efficient creation of a manufacturing model, including design drawings and processing instructions for the components that make up the product, from a design model, which is the design information of the finished product. By adding technical instruction information to be manufactured and assembled to the 3D CAD model (design model), technical instruction information for assembly and component manufacturing can be centrally managed (for example, Figures 6 and 7). This reduces redundant work such as creating new drawings for manufacturing from the design model during the manufacturing preparation stage, and prevents mismatches with the design model. Furthermore, by considering the assembly plan before creating the manufacturing model and creating it as a plan model, it is possible to create an efficient assembly plan and provide error-free manufacturing instructions for components. In addition, regarding the method of adding manufacturing information to the design model, this embodiment separates the design information and manufacturing information, making it possible to create an assembly plan and a manufacturing model with manufacturing information without interfering with the design work in the development phase. Furthermore, when creating the plan model, the plan model is created using data linked and copied from the design model, so even if changes occur in the design model, the changes can be quickly reflected in the linked data, and the plan model can be modified or corrected as needed. Furthermore, regarding the manufacturing model, data for the parts to be manufactured is extracted from the design model and plan model each time without the need for link copying. Therefore, even if there are design changes, the manufacturing model is created only after checking the revised design model and plan model. This ensures that changes to the design model are automatically reflected in the manufacturing model, preventing confusion in the manufacturing department. Furthermore, conventionally, assembly planning was carried out after the design model was released, manufacturing information was organized, and this information was communicated to manufacturing personnel in a different format such as paper. In contrast, with this embodiment, the work can be brought forward, and a plan model can be created and checked in advance using preliminary data of the design model at the layout stage. This makes it possible to improve the quality of drawings before the design model is released. Moreover, by updating the plan model after the design model is released and automatically generating the manufacturing model, it is possible to obtain effects such as data centralization (centralization of design model, plan model, and manufacturing model), reduction of man-hours, and prevention of drawing errors. Since the plan model can be automatically updated using linked copying from the design model, changes from the design model at 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.

[0032] Figure 9 shows an example of the hardware configuration of the manufacturing model creation apparatus 10 according to this embodiment. The computer 900 includes a CPU 901, main memory 902, auxiliary memory 903, input / output interface 904, and communication interface 905. The manufacturing model creation device 10 described above is implemented in the computer 900. The functions described above are stored in auxiliary storage device 903 in the form of a program. The CPU 901 reads the program from auxiliary storage device 903, loads it into main memory 902, and executes the above processing according to the program. The CPU 901 also allocates storage space in main memory 902 according to the program. The CPU 901 also allocates storage space in auxiliary storage device 903 to store the data being processed according to the program.

[0033] A program for realizing all or part of the functions of the manufacturing model creation device 10 may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be loaded into a computer system and executed to perform processing by each functional unit. Here, "computer system" includes hardware such as the OS and peripheral devices. Furthermore, if a WWW system is used, "computer system" also includes the homepage provisioning environment (or display environment). Furthermore, "computer-readable recording medium" refers to portable media such as CDs, DVDs, USBs, and storage devices such as hard disks built into the computer system. Furthermore, if this program is distributed to computer 900 via a communication line, computer 900 that receives the program may load it into main memory 902 and execute the above processing. Furthermore, the above program may be for realizing only a part of the functions described above, and may also be for realizing the above functions in combination with programs already recorded in the computer system.

[0034] As described above, several embodiments relating to this disclosure have been explained, but all of these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be carried out in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents.

[0035] <Note> The manufacturing model creation apparatus, manufacturing model creation method, and program described in the embodiment can be understood, for example, as follows.

[0036] (1) A manufacturing model creation apparatus according to the first embodiment includes means for creating a plan model in which manufacturing instruction information necessary for the assembly of a product is set for each component based on a design model which is design information for a finished product manufactured by assembling a plurality of components, and means for extracting component information of a component to be manufactured from the design model, and adding the instruction information of the component to be manufactured extracted from the plan model to the extracted component information, thereby creating a manufacturing model that includes manufacturing instructions for the component to be manufactured. This allows for the efficient creation of a manufacturing model, which includes design drawings and processing instructions for the components that make up the product, from a design model, which is the design information of the finished product.

[0037] (2) The manufacturing model creation apparatus according to the second embodiment is the manufacturing model creation apparatus of (1), wherein the means for creating the plan model creates and displays a 3D model for assembly plans by adding the plan model to the 3D CAD model of the completed body. This allows users to reference a 3D assembly plan model, which includes a plan model, without modifying the original 3D CAD model of the design model. This enables centralized management of design information and assembly instruction information.
