精密及超精密加工广泛用于生产中,但目前尚缺乏系统深入的研究,特别是刃口的锯齿度研究得很少,然而锯齿度严重地影响加工工件的表面光洁度。本研究工作系统地研究影响锯齿度及光洁度的因素及其形成本质,这对各个精密及超精密加工刀具都有参考意义,对提高我国精密加工水平是十分重要的。 Precision and ultra-precision machining are widely used in production. However, there is still a lack of systematic and in-depth research. Especially, the serration of the cutting edge is rarely studied. However, the serration seriously affects the surface finish of the machined workpiece. This research systematically studies the factors affecting the sawtooth and finish and the formation of essence, which is of great significance to all precision and ultra-precision machining tools, which is very important to improve our precision machining.
