Macro Programs Used in Profile Machining Based on Ellipse Contour in Numerical Control Programming

The concept of macro programs,the selection of a mathematical model,the method of ellipse contour in numerical control programming,and the profile machining principle of ellipse contour are introduced briefly in this paper.Various numerical control programs for rough profile machining and finish profile machining are developed using macro programs.This method can be used for the contour of all types of conic.
