摘　　要：以零件的工艺特征为基础,系统地研究了不同的机械加工工艺的编程方法。基本编程实现了机械加工工艺数控指令化。固定循环简化了典型加工工艺单元的编程,加工相同工艺内容用子程序编程,加工函数面用变量编程,加工零件族系列零件用参数化编程,加工自由曲面用CAM自动编程。同时通过数控编程技术的综合应用,实现了粗/精加工、自由平面轮廓倒圆角等工艺。Expounds the basic principle of programming in the perspective of Mechanical Processing Tech- nology （MPT）, and develops the environment for such various MPT. The Numerical Control （NC） direction for MPT is realized by basic programming, while simplified programming for typical processing unit by fixed cycle, identical MPT contents by sub-routine programming, functional surfaces by variable program- ming, part series process by parametric programming and free-form surface by automatic CAM programming. Meanwhile, by integrating the NC programming technology, some complicated technology is implemented such as the rough and finish machining, free surface contour fillet, etc.
