Abstract：Aimed at the problem of knowledge discovery within process planning information system, analyzedthe contacts and differences among traditional computer aided process planning system, processplanning information system and process planning information system based on knowledge discovery. Represented the design objective and architecture of process planning information system based on knowledge discovery, and established relative stand-alone process planning information system an dprocess planning knowledge discovery and management system, which the former including technicsresource management, computer aided process planning, route management and project management,and the latter including knowledge discovery algorithm sets and process planning knowled gemanagement module. Brought forward knowledge discovery algorithm sets which included kinds of
data mining algorithms, so as to adopted different methods toward different knowledge discovery work . An example of process planning knowledge discovery was represented based on the method ofrough sets.
 Keywords: Process Planning Information System, Knowledge Discovery, Knowledge Management,Rough Sets
