本文论述了渐开线直齿圆柱齿轮铲齿成形铣刀轴剖面肯形几何模型的建立方法，导出了齿形曲线的参数方程，进行通用Ａｕｔｏｌｉｓｐ程序设计，并举例说明调用程序绘图的方法。
In this paper, the method of establishing the geometric model of involute spur gear tooth milling cutter shaft profile was discussed. The parametric equation of the tooth profile curve was derived, the general Autolisp program design was given, and the method of calling the program drawing was illustrated.
