Abstract: It is extremely important for procedure of process design and the management of process data for product life cycle in Computer Aided Process Planning (CAPP) system, but there are many shortcomings with traditional CAPP system in these aspects. To solve these problems, application of workflow technology in CAPP system based on web- integrated Bill of Material (BOM) tree was discussed, and the concept of integrated BOM tree was brought forward. Taking integrated BOM as the thread, CAPP systematic technological process was analyzed, and the function, system architecture and implementation mechanism of CAPP system based on Browser/Server and Customer/Server modes were expatiated. Based on it, the key technologies of workflow management device were analyzed. At last, the implementation mechanism of integrated BOM tree was analyzed from viewpoints of material information encoding, organization node design of integrated BOM tree, transformation from Engineering BOM（EBOM）to Process BOM（PBOM）and the programming implementation technology .

Key words: process workflow, computer aided process planning, workflow management device, integrated bill of material
