Abstract: To change the automation-oriented Computer Aided Process Planning (CAPP) to aid-oriented CAPP, the concept of Assistant Process Repository (APR) was presented. The APR contained the basic process repository and rules repository, the contents of which were elaborated. Then, the APR was compared with Process Decision-making Repository on the aspects of content, knowledge-capture methods and repository-build expenses. The method and technology to capture the knowledge automatically were discussed according to the Knowledge Discovery Technology. These technologies included semantic matching, text clustering, association rules and series pattern analysis. Finally, an application example was given.

Key words: CAPP, knowledge repository, data mining, knowledge discovery
