| Abstract: | A CAPP integration system is introduced in this paper. The framework of the system,process and the functions are analysed. Several critical problems, such as the method of obtaining product data, the characteristics of technological decision making and the generation of sequence Graph are discussed in detail. All of process information of this CAPP integration system is transferred accurately in CAD by interface module, in such a way, the data is transferred immediately between CAD and CAPP and the data is shared. In this system, tool means is adopted, mixed technological decision based on example and knowledge is constructed, sequence Graph is obtained by model reconfiguration and feature assembling. It was proved that CAPP integration system is scientific and practicality with compatibihty. |
