Research And Application About CAPP Technology Used To Disc Break Pad

The CAPP is shortend form of computer aided process planning.The process planning is the first stage of preparation for manufacturing technical document.And it is the bridge between product design and product manufacturing.The process is the base of froch design,manufacturing,the method of machining and machining route.Its function is following:organizing produce,controlling quality,enhancing productivity, reducing cost,reducing produce periods,improving work conditions,etc.so,the process planning is the core part of production.This subject, in view of the practice of Disc break pad enterprise considers comprehensively the advancing and applying of the system, combines the Variant pattern and Generative pattern of CAPP planning method and meanwhile applies ES ideas, develops comprehensive RYCAPP_SABR1 system.This article introduces the development of CAPP in domestic and abroad nowadays and the development of its supporting theory and technique, it plans the whole structure of the system, analyzes the feasibility and meanwhile introduces the specific function of respective functional module of the system. It classifies and codes the products basing on the characteristic of the production.It sets forth the importance of database in CIMS, introduces briefly the general procedure of database planning, it establishes the system database for Satisfied Friction Materials Co.,Ltd. in view of the practical needs of its CAPP which includes craft rules database, process remaining choice database, equipment tool choice database and so on.It briefly introduces the export system and the indicating ways of knowledge in the system, assessing standard and reasoning of knowledge indicating ways, it also emphatically introduces the indicating way of generative pattern. It sets forth the essence and the method of craft decision, and realizes the adjustment of craft rules through relevant program, the obtaining of process remaining, and the choice of equiment to fulfill ultimately the craft decision process.Finally, it introduces the basic concept and the classification of computer network and the variation of computer network topology structure.lt sets up local network CAPP system directed against the practice of the enterprise.By way of application of RYCAPPSABR1 system, we standardize the process design of Disc break product, enhance efficiency and make the technologist have more time to research and develop the new products.These advantages have significance for our country developing automobile break independently and changing the condition that china in the field of automobile break heavly depend on other countries.
