Abstract:The three-dimensional machining process planning system is a hot trend in the development of CAPP. Achieving the guide of three-dimensional process to the production process is a key for the successful application of the three-dimensional machining process planning system in the enterprise. With a focus on the pivotal technic and difficulty of information extraction of DELMIA three-dimensional machining process model which is commonly used in auto and aviation fields, this paper describes how to apply V5 Automation secondary development technology in depth to extract three-dimensional machining process information, generate a three-dimensional machining process card and use it to guide the production, eventually forming a collaborative process management system based on three- dimensional environment.
