Abstract
Micro-textured technology which studies in the field of tribology shows that micro-textured surface can effectively improve the situation of friction between the friction interfaces. In this article, micro-textured surface technology has been applied to the cutting tools, in order to study the cutting mechanism of micro-textured carbide tools. The effect of cutting parameters on surface friction characteristics was studied when cutting 45 steel with YT15 cemented carbide tools. The results shown that all surface friction coefficient of the samples got the best value when the feed rate is 0.14mm/r; an appropriate increasing in feed rate can reduce the surface friction coefficient in the low-speed cutting. Throughout the course of the test, the average of the surface friction coefficient of the 4th and the 5th sample tools are better than other tools.
