数控加工刀具半径补偿的合理使用

The proper Usage of Tool Radius Compensation in Numerical Control Machining

阐述了数控机床刀具半径补偿的作用。应用刀具半径补偿虽给编程加工带来便利,但也会产生刀具偏置引起未切除量及相应的加工偏差。讨论了清除刀具偏置引起未切除量的编程问题,内轮廓加工时为避免产生未切除量而对程序的修改问题,以及建立及取消刀具半径补偿时应注意的问题。

Illustrating the importance of tool radius compensation in numerical control machines, this paper discusses the deviation of machining caused by offset of tool radius as well as the issues to care about during the process of establishing and lifting the tool radius compensation.
