The methods of compiling oval macro-program in turning operation

This paper discusses the principle of compiling oval macro-program. Through three examples, it analyses the methods of compiling oval macro-program in turning operation on the basis of ellipse standard equation and ellipse parametric equation. In addition, this paper, by applying simulation software to verify the compiled program, summarizes the programming essentials. This paper is of important reference value to machining components with non-circular curve contour in the NC machining.
