本文用画法几何图解法导出了棱体成形车刀法剖面廓形的几何模型，并编制通用Ａｕｔｏｌｉｓｐ程序，调用此程序，可绘制加工各种规则曲面零件的棱体成形车刀剖面之廓形。
In this paper, the geometrical model of prism profile tooling method is derived by the method of geometrical figure drawing, and the general Autolisp program is compiled. By calling this program, the profile of prism profile tooling profile for machining various regular surface parts can be drawn .
