摘　　要：简介了自滚切刀具的基本概念,分析了切削过程中的切削力,对自滚切端铣刀的切削力进行了试验研究,得出了切削力与刀具刃倾角、刀片直径及切削速度之间的关系。试验结果表明,刃倾角对自滚切刀具的合理使用最为重要,各切削分力随刃倾角不同的变化规律源于刀刃工作前后角的变化;较小的刀片直径有利于减小切削力,使切削过程更加平稳;自滚切刀具特别适合于高速切削,较普通刀具切削速度可提高50%以上。The basic concepts of self rotary cutting tool is presented firstly, and the cutting force be analyzed theoretically, the relationship between cutting force and inclination angle, diameter of round insert and cutting speed is experimentally researched with self rotary face milling cutter. The results revealed that inclination angle is the key geometry parameter, who leads to the change of working rake and clearance angle, hence the differential tendency of the three components of cutting force. Less diameter of insert will leads to the decrease of cutting force and the cutting process more smoothly. High speed is suitable for self rotary cutting tool and the cutting speed will be 50 percent higher than commen tool.
