Development of CAPP System for Aerospace Ring Forgings Based on WEB

This work aims to design and implement the CAPP system of aerospace ring forgings based on B/S architecture mode, to improve the process design efficiency of aerospace ring forgings, ensure the consistency of product process design, and realize the automation and intelligence of ring forging process design. Firstly, according to the process design theory of ring forgings and combined with the process design requirements of ring forgings in the actual production process, the process design flow of ring forgings was analyzed, and the process design rules of ring forgings were refined. Then, the CAPP system architecture of ring forgings was designed according to the requirements of ring forging process design and user requirements. C# was selected as the back-end development language of the system, and the system interface was developed by HTML, CSS, and JavaScript technology. SQL Server was selected as the system database, and the development of each function module of the CAPP system was carried out with the MVC framework. The CAPP system of ring forgings was designed and implemented, which incorporated four system function modules:process preparation, ring information management, knowledge base management, and user management. After the new ring information was imported into the process preparation module, two design modes based on rules or machine learning could be selected for the process preparation of ring forgings. The standardized process cards could be automatically generated, and the process design time could be shortened by 90% compared with manual design. CAPP system of ring forgings has good process design capability of ring forgings, which can significantly improve the process design efficiency and consistency of ring forgings.
