[0002] In high-end manufacturing, especially in the design and manufacturing of aviation products, processes are the cornerstone of design, and process specifications are a key means of ensuring product quality and achieving qualified product delivery. Process specifications are a set of regulations that define the technical requirements of a process and are standardized documents. For the digital manufacturing of aviation products, the development of process specifications should be the result of forward design, coordinated with design and materials, and closely integrated with process R&D activities. However, the current process of generating process specifications is mostly based on the engineering experience of process designers. The experience and level of these designers directly determine the quality of the generated process specifications, resulting in a lack of forward design capabilities and a failure to comprehensively consider the process specification requirements for product quality, economy, and processing efficiency. Furthermore, the development of process specifications lacks the support of relevant process knowledge and systematic verification, resulting in a high number of process optimization iterations. The technical data sources for many process specifications are unclear and unscientific, impacting product processing quality, production costs, and efficiency. There is a lack of corresponding digital, modular, and knowledge-based systems to support the rapid generation of process specifications, design selection, the compilation of process technical documents, and digital transformation.

[0046] The following problems currently exist in the process of forming digital manufacturing process specifications for aviation products:
[0047] There is a lack of a process specification generation mechanism that collaborates with forward design and manufacturing. Currently, the process specification generation process relies primarily on the engineering experience of process designers, whose experience and level directly determine the quality of the process specifications. Many process data sources are unclear and unscientific, and process R&D activities are disconnected from the formation of process specifications, impacting the manufacturing level of the product. There is a lack of a demand model that comprehensively considers product quality, economy, and processing efficiency. The core technical content of process specifications lacks the acquisition and support of process knowledge. The establishment of a process knowledge base and related algorithms fail to couple with design requirements and test data. There is a lack of a standard verification method for systematic specifications. Currently, the process of generating digital manufacturing process specifications for aviation products lacks comprehensive standard verification, including verification steps for intermediate stages of different products. This results in a serious accumulation of product manufacturing errors, a high rework rate, and slow problem resolution.
[0048] Based on the above problems and the current status of digital manufacturing of aviation products, a method, system, equipment and storage medium for generating product manufacturing process specifications are provided. By constructing a process specification demand model, carrying out process research and development activities, and utilizing the process knowledge and logical algorithms formed by experimental data, process specifications that meet product quality requirements, production costs, and production efficiency requirements are positively formed. Through a building block verification method, the standardized and scientific compilation of process specifications is promoted, thereby guiding the digital research and development and production of aviation products.
[0049] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0050] like Figure 1 As shown, the method for generating product manufacturing process specifications provided in this embodiment specifically includes the following steps:
[0051] S100. Construct a process specification requirement model for product manufacturing that includes product quality, production cost and production efficiency requirements.
[0052] In some embodiments, before constructing a process specification requirement model for product manufacturing that includes product quality, production cost, and production efficiency requirements, the process also includes: formulating a predefined process specification template that matches the product manufacturing goals based on the design requirements of the product manufacturing.
[0053] In some embodiments, constructing a process specification requirement model for product manufacturing that includes product quality, production cost, and production efficiency requirements includes: constructing the process specification requirement model according to the design requirements of product manufacturing and a preset process specification requirement model construction method.
[0054] In this application, a system for generating manufacturing process specifications based on the proposed method is provided, embodying the core concept of the implementation method. The system consists of software and hardware, encompassing four modules: model building, data acquisition, specification generation, and process knowledge base construction. Data transmission, access, and storage between these modules are achieved through human-computer interaction.
[0055] The model building module mainly inputs the product design requirement information and the process specification requirement model. In the aforementioned system, human-computer interaction is used to extract the product design requirements and confirm them, and then input them into the process knowledge base after confirmation; in this module, according to the provided process specification requirement model construction method, the process specification requirement model is established and the model is transferred to the process knowledge base.
[0056] The process specification requirement model has the following model formula: comprehensive target value = a × product quality value + b × production cost value + c × production efficiency value. The higher the comprehensive target value, the more scientific and reasonable the generated process specification is. In the formula, a, b, and c represent the weights of product quality, production cost, and production efficiency, respectively, where a+b+c=1. In the initial value of the model, the a value is 0.7, the b value is 0.15, and the c value is 0.15. The weights can be adjusted according to actual production conditions and needs. When the product quality meets the requirements, the product quality value is 1, and the production cost in the formula is calculated as follows:
[0057]
[0058] Production cost value = f(E) / E n
[0059] Where f(E) represents the average production cost for n process items; E n Represents the production cost of a single process.
[0060] It can be seen from the formula that the higher the production cost, the smaller the production cost value. When the single production cost value (E n ) is greater than the average production cost (f(E)), its production cost value is less than 1. When the production cost is less than the average production cost, its production cost value is greater than 1. The method for calculating the production efficiency value is the same as that for calculating the production cost value.
[0061] Enter product quality, technical requirements, and other information into the model building module to conduct demand analysis. Build a comprehensive process specification demand model that encompasses objectives such as product quality, economic efficiency, and production efficiency. Assign weights to each objective and save them in the process knowledge base.
[0062] S200: Acquire process-related test data from a pre-conducted product development process to obtain a process data sample.
[0063] In applications, the data acquisition module is used to capture test data from the product development phase. This module integrates the digital manufacturing process, extracts job files, and analyzes and captures data related to personnel, tooling and equipment, materials, process parameters, and test results. Furthermore, human-computer interaction allows for input of relevant test data generated during the manufacturing process by task number or batch, and transfers this data to the process knowledge base.
[0064] According to the requirements of the process specification template, the data acquisition module collects process-related test data, mainly including personnel, environment, material information, process flow, process parameters, test methods, product quality, production costs, production cycle, etc., to form a process data sample. After data collection, it is stored in the process knowledge base by batch or task number.
[0065] S300 : Generate a process specification that meets target requirements based on the process specification requirement model and the process data sample.
[0066] In some embodiments, generating a process specification that meets the target requirements based on the process specification requirement model and the process data sample includes: generating a draft of the process specification based on the predefined process specification template, the process specification requirement model and the process data sample; and performing different levels of verification through trial production samples based on the draft of the process specification to generate a final draft of the process specification that meets the target requirements.
[0067] In some embodiments, generating a draft of the process specification based on the predefined process specification template, the process specification requirement model and the process data sample includes: randomly selecting process parameter data from the process data sample and matching it with the process specification requirement model; calculating the comprehensive target value through Monte Carlo simulation analysis, and analyzing the confidence interval and allowable value of each parameter that meets the design requirements; generating a draft of the process specification based on the predefined process specification template, the confidence interval and allowable value of each parameter.
[0068] In some embodiments, the process of performing different levels of verification through trial production samples based on the preliminary draft of the process specification to generate a final draft of the process specification that meets the target requirements also includes: determining the trial production sample size and the initial range of process parameters based on the design requirements of product manufacturing; and constructing the trial production sample through a building block verification orthogonal matrix based on the trial production sample size and the initial range of process parameters.
[0069] In some embodiments, based on the preliminary draft of the process specification, verification at different levels is performed through trial production samples to generate a final draft of the process specification that meets the target requirements, including: based on the preliminary draft of the process specification, verification at the material, component, assembly, and part / component levels is gradually performed through trial production samples; and based on the verification results, the preliminary draft of the process specification is iteratively optimized to generate a final draft of the process specification that meets the target requirements.
[0070] In the application, the specification generation module is used to generate process specifications, including the creation of process specification templates, the initial draft, and the final draft. Experimental data, relevant process knowledge, and demand models are retrieved from the knowledge base. Through simulation calculations, the initial draft of the process specification is generated. Using the proposed building block verification method based on orthogonal matrices, a trial production sample model and verification method are constructed, and iterative optimization is performed to produce the final draft of the process specification.
[0071] The process knowledge base construction module is used to store and transmit all process data in the process of forming process specifications, including knowledge such as personnel, equipment, materials, process parameters, models, algorithms, process specifications, etc.
[0072] The specification generation module provides a building block approach to process specification verification based on an orthogonal matrix. Leveraging the product development process, it conducts trial production sample construction and verification at different levels, including materials, components, assemblies, and parts / subassemblies. Verification at different levels is performed for key indicators and product processing, ensuring that all technical conditions during the processing meet product design requirements, thereby ensuring the performance, reliability, production efficiency, and cost of the final product.
[0073] The construction of trial production samples is a fundamental prerequisite for conformity verification. Small sample sizes can lead to inadequate process verification, while large sample sizes can incur high costs. The trial production sample model in this application includes information such as sample quantity, materials, and process parameter ranges. By inputting key design and process requirements, the trial production sample size and initial process parameter ranges are automatically calculated.
[0074] Materials verification is used to test and evaluate the processability of raw materials used in product manufacturing, primarily verifying their chemical composition, physical properties, mechanical properties, and processing performance. In addition to ensuring that product performance requirements are met, materials verification also helps optimize material selection and reduce production costs.
[0075] Component verification is based on the draft of the process specifications to determine and confirm whether the process specifications can meet the design requirements, safety requirements, and performance, and to conduct reliability assessment and preliminary confirmation analysis of the process specifications.
[0076] After the component verification, the assembly is verified to confirm the compatibility between the interfaces and to determine whether the expected compatibility, performance, safety, reliability and other indicators are met.
[0077] Parts / Components Verification After the assembly verification mentioned above meets the design requirements, parts / components verification is carried out. It is an important step to ensure product quality and reliability, help reduce the risk of product failure, and improve the efficiency and quality of the entire product production process.
[0078] The knowledge base provided by this application is an open, easily scalable, and flexibly configurable platform. The knowledge mainly includes process data, models and algorithms, process specification templates, and process specification cases.
[0079] Process data refers to the collection of data generated during the manufacturing process. This includes personnel, equipment, design requirements, material data, process flow, process parameters, test or inspection data, product quality, labor hours, and production cycle times. Process data can be manually entered, or it can be automatically acquired by reading and digitizing the process plan information of the manufacturing process.
[0080] The models and algorithms include process specification requirement models, trial production sample models, and simulation algorithms.
[0081] The process specification template consists of two layers: one that records typical process specification templates and the other that allows customization of individual modules, which can then be combined to create new process specification templates. The process specification framework and initial process parameter values are stored. When developing a process specification template, you can directly select and match it, and customize the template and process parameters as needed.
[0082] The process specification cases described include published process specifications, including information such as applicable product requirements, release time, and process specification content.
[0083] The process knowledge base constructed in this application is the prerequisite for developing process specification templates. Designers or process engineers can retrieve from the process knowledge base and develop predefined process specification templates that match their goals based on product type, product characteristics, and quality requirements. They can also set initial values for various process parameters in the user interface based on design requirements.
[0084] Retrieve matching process specification requirement models, process specification templates, and process knowledge from the knowledge base. Using Monte Carlo simulation, randomly select process parameter data from the process parameter knowledge base and match them to the process specification requirement model. Using Monte Carlo simulation analysis, calculate the comprehensive target value and analyze the confidence intervals and allowable values of each parameter to meet design requirements. This creates a preliminary draft of the process specification.
[0085] Prototypes are trial-produced by constructing a building block verification orthogonal matrix. Based on the prototype, verification is performed at different levels, targeting materials, components, assemblies, and parts / subassemblies. The processes and parameters in the process specifications are verified to ensure that each process achieves the expected results and verifies compliance with the process specifications. Based on the verification results, the process specifications are iteratively optimized to produce the final draft.
[0086] The following is described by specific examples:
[0087] Product designers propose quality, technical, and safety requirements for the product realization process as input for generating process specifications and storing them in the process knowledge base. Process engineers retrieve design requirements from the knowledge base and, based on these requirements and production conditions, develop a process specification template, build a demand model, store it in the knowledge base, and create a product processing batch number or task number.
[0088] Based on their requirements, process engineers or operators can collect test data from the process specification template automatically or interactively, creating a data set that is stored in the process knowledge base by batch or task number. Furthermore, the process knowledge base can be used to directly match the corresponding process data and assign initial values to process parameters.
[0089] Process engineers retrieve the process data requirement model from the knowledge base and, through simulation calculations within the system, analyze the confidence intervals of each process parameter to produce a draft process specification. Based on the draft process specification, they retrieve the building block verification orthogonal matrix from the knowledge base and, through process parameter input and design, construct a trial production sample and verification plan for the process specification.
[0090] Based on the verification plan, a verification outline is compiled. Production and processing of materials, components, assemblies, and parts at different levels are performed according to requirements, and testing is performed as required. Processing and testing results are stored in the knowledge base by batch or task number. Product designers and process engineers confirm the product test results, and process engineers optimize the process within the system based on the results. Based on the verification process, a verification report is generated, and the process specifications and verification report are submitted to management for review and release.
[0091] The method for generating product manufacturing process specifications provided in the embodiment of this application is as follows: Figure 2 As shown in the figure. For the digital manufacturing process of aviation products, a process specification generation method and system based on forward design and knowledge collaboration is developed. By building a process specification requirement model, conducting process R&D activities, and utilizing process knowledge and logic algorithms formed by test data, process specifications are forward-formed to meet product quality, production cost, and production efficiency requirements. Furthermore, through a building block verification approach, the standardized and scientific compilation of process specifications is promoted, thereby guiding the digital development and production of aviation products.
[0092] The process specifications generated by this method and system can get rid of the dependence on manual experience. With the help of knowledge acquisition and coupling, they can guide the precise writing of process technical documents, reduce the number of process iterations, reduce production costs and improve production efficiency. At the same time, the process specifications can be stored in a digital form in the knowledge base, promoting the digital transformation of aviation manufacturing.
