变半径补偿宏程序在轮廓倒圆角中的应用

摘要

This paper introduces the programming method of macro program and some problems needing attention in milling combined with cases. Through the real example , the highly effective application of changing the radius to compensate macro-program of FANUC 0i system is discussed and is also verified in BEIJING FANUC Series Oi Mate-MB system.%讨论了用球头铣刀铣削零件边缘凸圆角的编程和加工方法.按零件的轮廓尺寸编制程序,借助宏程序改变补偿的半径值,即找出具有通用性的变半径关系式,利用变半径进行补偿,完成轮廓边缘凸圆角的编程.通过实例,阐述FANUC 0i数控系统变半径补偿宏程序的应用方法,并在BEIJING FANUC Series 0i Mate-MB数控系统中得到了验证.
