数控程序作为将设计转化成现实的信息载体,直接控制机床的切削动作,是数控加工的关键.随着计算机技术的迅速发展,计算机数控与CAD/CAM软件不断推陈出新,性能越来越完善,功能越来越强大,并且代表了以后机械制造业的发展方向.但我国制造业中数控技术与CAD/CAM技术应用水平仍然非常低.%The NC program is the information carrier making the design into reality. It's also control the machine's cutting action directly and it is the key of numerical processing. As the rapid development of computer technology, computer numerical control and CAD/CAM software update day by day. The performance of them is more perfect and the function is more powerful. They're also the development direction of machine-building industry. But the application level of numerical control technology and CAD / CAM technology in China's manufacturing industry is still very low.
