摘　　要：在数控铣床上加工轮廓零件时,刀位点的运动轨迹偏离编程轨迹。此时,合理利用刀具半径补偿指令,能够简化编程和提高加工质量。基于此,就刀具半径补偿指令的功能、建立与取消,以及如何通过改变刀具半径补偿值来实现粗加工和精加工进行探讨。When machining contour parts on CNC milling machine, the movement tracks of tool locus deviates from programming trace. At this point, reasonable use of tool radius compensation instructions, can simplify programming and improve the quality of processing. Based on this, the function, establishment and cancellation of tool radius com-pensation instruction, and how to realize the rough machining and finish machining by changing the tool radius com-pensation value were discussed.
