Capp System Based On The Structure Of The Bom

In modern mechanical manufacturing industry, CAPP (Computer Aided Process Planning) has important theoretical values, comprehensive and exigent needs. CAPP is a major component in CLMS(Computer Integrated Manufacturing System). The speed and quality of process planning can be improved greatly by using CAPP. The standardization and regularization of process planning can also be enhanced. With the fast development of advanced manufacturing technology and information technology, process information system should satisfy new needs. CAPP not only acts as a tie which joins CAD and CAM systems together, but also keeps close links with other systems such as ERP, PDM, etc. in the construction of manufacturing information. Therefore, CAPP has been regarded as an important research field of modern manufacturing technology.On the basis of the sum-up and analysis of the trend of development of CAPP and its present status of application, the author is determined to make some research in this paper as follows.The method of CAPP system based on the Structured BOM is put forward; the structure, process and function of CAPP system based on the Structured BOM are expounded. A new idea of generating the process plan system based on knowledge template is proposed. The concept of prototype process is discussed, and its generation mechanism and methods for building process base are studied. Furthermore, the generation of objective process from prototype process is patterned. The method is of great importance for the flexibility and practicality of process planning system. The system is of characteristic of tools model which provide a lot of tools module. Object Oriented storage and management model of resource data is researched and an open data base management system of process resource is building. Rational management of process resource data is achieved. The importance of integration is analyzed, the method of the integration of CAPP and MES based on Structured BOM is proposed.The system can satisfy the needs of the construction of manufacturing information, in practical application.
