摘　　要：通过分析切断和切槽的加工过程,说明现有的G75固定循环的作用及局限性,提出用宏程序编程完成切槽循环的方案,其切槽进给速度和每次进刀距离随直径变化而逐渐减小,使切槽和切断更为有效、合理。The processes of grooving and cutting were analyzed. The advantages and limitations of cycle G75 were discussed. A project of using macro program to implement groove processing cycles was put forward. In the program, the feed rate and loop distance were varied with the change of the workpiece diameter. Thus the processes of grooving and cutting are more reasonable and effective.
