摘　　要：用球刀层切法精铣椭圆斜孔时的刀心轨迹是一个包含下刀高度变量和椭圆转角变量的参数方程,据此参数方程可用2个嵌套的循环语句编写宏程序,并实现程序的参数化,然后设置成铣椭圆斜孔固定循环G代码,用于精铣椭圆斜孔和圆台形孔的数控编程。The cutter center track of precision milling an elliptic slant hole by spherical layer cutting method is a parametric equation, which contains variables like knife height and elliptic corner. Based on the equation, the macro program can be written by two loop statements, and then the parameterization of programming was achieved. A fixed cycle G-code was set as a program for milling the elliptic slant hole and truncated cone-shaped hole.
