Research And Development Of Intelligent CAD/CAM Integrated System Based On CE For NC Milling Machine

The subject stems from the project provided by the scientific and technological bureau of Guangxi. The title of the project is "Informational application demonstration project for the manufacturing industry in Guangxi -development of the general platform system for numerical control machine tool with the function of lathing, milling, punching and linear cutting (No.0228018)". It is requested to research and develop a suit of general integrated platform system with independent copyright for numerical control machine tool with the function of lathing, milling, punching and linear cutting. This paper mainly exoatiates on the technology and method of research and development of intelligent CAD/CAM integrated system based on CE for NC milling machine.The following solutions is adopted, through studying the CAD/CAM integrated system for numerical control milling machine .Firstly, there are main research contents : (l)The basic function of the two-dimentional CAD module .including basic drawing function, figure editing function and auxiliary drawing function, etc.; (2)The basic function of the CAPP module, including the processing technology information of the level outline milling and the level area milling; (3) The basic function of the CAM module, including setting up cutter manager, tool path generating, tool path simulating, and numerical control code automatically producing.Secondly, there is the main key technology: (1) The system with the function of concurrent designing; (2) The user interface , structure and function of the system is analysed and designed by UML; (3)The artificial intelligenttechnology is applied to CAD module ; (4)The parameter general post processor is adopted. (5)Programming adopts object-oriented technology.Conclusion: The system developed passes the test in the numerical control milling machine laboratory of the institute. It indicates that its design is effective and rational, development of the project lays a very good foundation for further perfecting itself and realizing three-dimension designing and 3D NC processing.
