As the rate of the NC manufacturing equipment continue to improve, CNC machining technology in China are increasingly widely used in the mold industry, control or numerical control technology and the processing rate of the level of the NC has bee a symbol of whether the petitive . CNC machining technology is the key to puteraided design and manufacturing (CAD / CAM) system quality. How to prepare for NC machining program is CNC machining efficiency and quality of the key, the traditional manual programming methods plex, cumbersome and errorprone, difficult to check, it is difficult to give full play the function of CNC machine tools. In the mold, often experiencing plex shape parts, the shape used to descr ibe the free surface, using manual programming method is basically not prepared NC program. In recent years, due to the rapid development of puter technology, puters have greatly enhanced graphics capabilities, based on CAD / CAM technology for automated interactive graphics programming matures, this method is fast, high precision, intuitive, easy to use and easy to check. CAD / CAM technology in the industrial countries has been widely
