摘　　要：铣削加工是采用多齿刀具进行断续切削的一种加工方法,为了对铣削力进行比较准确的测量,设计了铣削力测试系统。在断续切削中,切削力波形可被看作周期性函数,如果将其分解为各个频率的分量,可以认为它是由一个按特定的基本频率变动的正弦波形的切削力分量和许多个按基本频率的整数倍而变动的正弦波形的切削力分量叠加而成,本文所讨论的正是这种在断续切削条件下所特有的动态切削力,并着重研究它在时域及频域中的特性。对五种刀片进行了实验研究和槽型对比分析及优选,从而为刀片槽型优选提供一定的依据。Milling machining is an incontinuous cutting method with multi-teeth cutter. In order to get the accurate milling force, the milling force testing system was designed. The wave shape of milling force can be looked as periodic function. If we divide the function into a series of frequency, we can find that it is composed of sine wave cutting force with a given frequency and a series of integer multiple frequency. This paper deal with the dynamic milling force in incontinuous cutting condition, especially the characteristic of time and frequency. By the experiments and groove contrast analysis with five types of milling inserts, so definite basis for the groove optimization was offered.
