摘要：
It is extremely important for procedure of process design and 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 respects. To solve these questions, application of workflow technology in CAPP system based on web-integrated Bill of Material (BOM) tree is discussed, and a concept of integrated BOM tree was brought forward. Taking integrated BOM as the thread, CAPP systematic technological process is analyzed. The function, system architecture, and implementation mechanism of CAPP system based on Browser/Server and Customer/Server model are expatiated. Based on it, the key technologies of workflow management device were analyzed. Eventually, 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.
