摘　　要：当前市场上的数控系统均无椭圆台型腔加工固定循环功能,一般也没有椭圆插补功能。为了扩展数控系统的功能,通过建立用球刀加工椭圆台型腔的数学模型,计算出了刀心变高切削等高线时的刀心坐标,并编写了宏程序,然后设置成椭圆台型腔加工固定循环G代码,给出了椭圆台型腔加工的误差预测方法。可用于椭圆台型腔、圆变椭圆型腔、圆台形型腔、椭圆柱型腔及圆柱形型腔的数控编程,并通过实例验证了数学模型及宏程序的正确性。There is not the fixed cycle programming functions to machine elliptical cavity in CNC systems on the market. These CNC systems generally have not elliptical interpolation function.This paper established a mathematical model of contour cutting method to calculate the tool point coordinates, and programmed a macro for it, then set it to fix cycle G-code, given the error prediction method. It can be used to program for elliptical cavity, circle -elliptical cavity, circle round table-shaped cavity, elliptical cylindrical cavity and cylindrical cavity, it was proved that its correctness in experiment.
