摘　　要：在加工有椭圆形状零件时,采用何种编程方法提高编程效率是编程员较难定夺的问题.通过对椭圆标准方程和参数方程不同的处理方法进行比较,进而讨论直线逼近和圆弧逼近方法的不同,得出直线逼近比圆弧逼近高效,后者比前者精度有所提高的结论.When processing elliptical shape parts, it is difficult for programmers to decide which programming method should be adopted to improve programming efficiency. In this paper, two different methods of elliptic standard equation and parametric equation are compared, and then the difference between straight line approximation and circular arc approximation is discussed. It is concluded that straight line approximation is more efficient than circular arc approximation, and the accuracy of the latter is higher than that of the former.
