The systematic methods of process planning knowledge discovery about professional knowledge, experience and criterion in process planning work become the key problem in CAPP system. Process planning knowledge model is analyzed oriented process planning knowledge discovery problem in CAPP system. Process planning knowledge discovery technology based on knowledge model driving is researched and is applied in CAPPFramework system (a CAPP development platform supported by 863/CIMS in China). The practical application of knowledge discovery technology in CAPPFramework is described in detail, it can automatically achieve the knowledge in process planning database by the interaction with knowledge engineer.
