The research of CAPP base on information table

According to the needs of intelligent computer aided process planning, combined with the method of parts elements describing and the method of parts classification code, an information model of parts can be build up. The knowledge base is set up with the help of the success stories. According to the method designed in this paper, based on the knowledge base for inference processing technology needed for reasoning, automatic processing methods derived option. Hole finishing with an example, utilize 20 success stories, Of 9 test cases to test alternative processing methods to achieve 100% accuracy rate.
