RESEARCH ON KEY TECHNOLOGIES OF USER FRAME SYSTEM IN CAPP DEVELOPING TOOL

The CAPP developing tool is a necessary method to realize commercial CAPP and CAD/CAPP/CAM integrated system. The CAPP developing tool proposed in this paper is composed of Constructive Tool System and User Frame System. Customers use the User Frame System to create process plan based on Constructive Tool System. It has the following functions: reading user system information template, reading and checking part information, creating process plan, outputting process documents and machining information. The key technologies of User Frame System are discussed in detail: manufacture feature class definition for all system features and user defined features, process sequence and optimization based on flexible process decision-making, process information operation based on part process structural tree. The CAPP developing tool has been used to realize two CAPP systems for non-rotational parts.
