数控床车的几种椭圆加工方法

在教学和工作实践中常面对着如何加工椭圆零件的问题，但不同的数控系统实现椭圆加工的方法有所不同，尝试对各种常用数控车椭圆加工方法进行总结探讨，论述了宏程序法、椭圆指令法、参数修改法和自动编程加工法等数控车常用椭圆加工方法。

Several Ellipse Machining Methods of CNC Lathe Work

The processing problems of el iptic parts are of ten faced with in the teaching and practice,but the machining methods are different in the el ipse machining CNC systems, This paper attempts to summarize various el ipse machining methods commonly used on the numerical control lathe,This paper discusses the macro,el iptical instruction,parameter modification and automatic programming processing and so on,which are commonly used in the el ipse machining process.
