摘　　要：在教、学、做一体化的教学过程中,学生根据零件图的尺寸与轮廓能够编制出数控零件加工程序,但是加工出零件总是与零件图的尺寸与轮廓相差一个刀具半径补偿值,造成过切或少切。针对数控生产实训教学过程中出现上述的问题,首先介绍了刀具半径补偿G41/G42、G40指令的使用注意事项,并结合在FANUC 0iM系统数控铣床的加工零件实例,重点阐述了用刀补指令如何实现多功能切削加工,为数控生产实训教学过程节约生产成本,同时为中小企业的操作员工技能培训奠定了实践基础。According to part drawing＇s size and contour,the students can program manually NC machining program in teaching integration process.But the work-piece＇s size after machining and dimensions of the part drawing is always different with one cutter radius offset,which causes more or less cutting.According to the problem in the teaching procedure of the CNC production training,points for using attention of the G-code of the tool radius offset directions（G41,G42,G40） are introduced.Next,parts processing example using FANUC 0iM system in CNC milling machine is elaborated with how to realize multi-function cutting machine by using the G-code of the tool radius offset direction（G41,G42,G40）.It saves the cost of production for teaching integration process of the CNC production training,and is the basis for skill training of the operator in small and medium enterprises.
