摘　　要：利用圆头车刀在数控车床上加工圆弧曲面零件时,使用不当常会发生过切、少切、撞刀等现象。文中就圆头车刀的应用特点、对刀方法、刀尖圆弧半径补偿的设置及编程等方面进行了阐述,并绘制出刀具运动轨迹图,分析了加工时易出现的编程方面的错误,提出了使用刀具半径补偿的注意事项。While using round-nose turning tool, overcutting, undercut and collision would happen if used improperly. The paper introduces the application of round-nose turning tool,including the method of tool setting and the setting and programming of corner radius compensation. The motion diagram of the tool is drawn, the program errors during processing is analyzed. The instruction while using radius compensation is put forward.
