Research on PPKM technology based on object-oriented model driving

In order to solve the problem of knowledge acquisition in computer aided process planning(CAPP) application system,the concept of process planning knowledge mining(PPKM) was proposed.The technology architecture of process planning knowledge mining was founded based on object-oriented model driving technology,and the process planning knowledge mining script was designed.Elementary application research in typical operation summarization was described in detail.The technology architecture of PPKM could be used to achieve the automatic knowledge acquisition of data accumulating in CAPP system.
