Study and Its Implementation on the CAPP System for Middle Small-Scale Machine-Building Manufacturers

Analyzing the characteristics of middle small-scale manufacturers on the basis of actual investigation a CAPP system is designed to adapt to machine-building manufacturers. Finds out the features of technological documents, and the IDEF0 modeling process is introduced to determine the functions required for CAPP, including process planning, management, integration, etc., thus the make up of the CAPP system. Then, the CAPP system architecture and its main modules are designed and implemented to fit in with the requirements of middle srnall-scale machine-building manufacturers.Some key techniques are discussed, including the data exchange between CAPP and PDM, realization of products structure trees and denotation of special symbols, Describes the way to implement the CAPP system which has been deployed by Shenyang Valve Manufacture Co., Ltd and with very good effect obtained in application.
