The Research And Application Of Integrated CAPP System Based On PDM

Computer Aided Process Plan (CAPP) is an important element and one of the information resource of Computer Integrated Manufacturing System (CIMS), and also is a key for the enterprises to realize information integration. With the deep development and wide application of CIMS, we emphasize on the integration of information as well as integrated cell technology. So the research of integrated CAPP system has great theoretic and practical meaning.With the research of the project "the development of numerical process planning integration platform faced the agility manufacture", which is sponsored by Sichuan Province, the total structure of CAPP integrated system based on PDM and the theory and implementing methodology of it are put forward in this paper. In CIMS environment, CAPP system based on PDM is a dynamic process information system facing multi-input and multi-output, practical producing, and integration of process design and process management. The author also analyzes the content and duty of process design progress management, and the method to apply it to the CAPP system based on PDM. Based on the theories above, a CAPP system suitable for manufacturing enterprises is drawn out. And the design of its overall structure, software interface, function module and database are all discussed in detail.The developing language of this system is Delphi6.0, which is owned toBorland Corporation. The supporting database is Microsoft SQL Server7.0. The system runs on Windows2000 or Windows98 operation system. It is based on object-oriented design method, has friendly interface and can work stably. The system can complete the "what you see is what you get" process design, the process files editing, querying, user management, version management, manufacturing resources management and process information calculating.
