Research On The Development And Key Techniques Of Process Planning Information Integrated Platform For Manufacturing Enterprises

CAPP is a key issue in advanced manufacturing system. It is the link between digital product design and manufacturing, it has great importance with the quality and cost of product. In this dissertation, based on substantive CAPP research and engineering software development in China, the concept of process planning information integrated platform (PPIIP) is put forward for discrete manufacturing enterprise. Key techniques of the technology architecture, information model, process planning data management, process planning data mining, integration technique, application and implement mode are researched in detail. It helps the generalization, exoteric, practicability, integration, toolization, specialization, and industrilization of CAPP system development and application. On the basis of the research and development of PPIIP, it's the expectation that a foundation technology platform of CAPP is provided, and an effective way of the realization for manufacturing enterprise process planning informalization in China is strive hard to come. The main points are summarized as follows:1. Based on the research of advanced manufacturing technology and manufacturing enterprise process planning informalization, the actuality of CAPP is analyzed for discrete manufacturing enterprise, the problems of CAPP in China are pointed out. The concept of process planning information integrated platform is proposed on the basis of modern CAPP.2. On the basis of domain engineering software development, the development architecture of PPIIP is founded. The functional framework and system architecture is summarized in detail based on component technology. The comprehensive technology architecture of PPIIP for manufacturing enterprises in China is proposed. Key techniques that include application scheme of PPIIP for industrilization and rapid development, integrated manufacturing data management for knowledge, the new-style intelligent process planning based on knowledge, integration technology, the exoteric management style of process planning resource, etc. are described.3. Based on the software system development mode of MVC, the general manufacturing enterprise process planning model is proposed. The information model driven mechanism of PPIIP is put forward. The information model representation architecture based on object class, object method, rule and procedure knowledge is proposed depend on object-oriented technology. The foundation model and application model of PPIIP is analyzed. The specification of information model and data is researched with XML, it helps the representation, exchange and share of information model and data. Based on the information model driven mechanism, the intuitionistic process planning tool is developed, and graphic flow chart process planning is researched ulteriorly and the exoteric characteristic of PPIIP is validated.4. The framework of process planning database is proposed on the basis of information model driven mechanism and the process knowledge database in PPIIP.The framework of process planning data management that adopts MBOM as core is proposed. The concept of process planning data mining in CAPP is proposed. The process planning data mining technique is researched based on PPIIP and the PPDML is developed also. The application on typical operation summarization, typical process summarization and process optimization with process planning data mining technique is researched to improve the intelligentize, standardization of CAPP system.5. The concept model of information integration, function integration, procedure integration and knowledge integration is proposed. The concept of single source of process planning data is put forward for information integration. The research scheme on process planning information integration based on bar code that reference to advanced manufacturing data management technique in abroad is presented. The function integration and procedure integration based on component in PPIIP is researched also. Key techniques of custom-built development architecture and interface specification is researched to meet the different integration requirement in PPIIP.6. The development, application and implementation of CAPP system is researched, and the application standardization and specification for PPIIP is proposed that includes foundation specification, management specification and application specification, etc. to help the development and implementation. On the basis of the research and application in airplane manufacturing industry, the concept of industrilization manufacturing process planning system is proposed. Key techniques of MBOM management system that adopts process planning subassembly as core, the realization of AO and FO intuitionistic process planning, airplane assembly process planning that adopts AO as core, part manufacturing management based on FO are presented in detail.
