The Influence of Bionic Micro-Texture’s Surface on Tool’s Cutting Performance

Abstract

Related researches of bionic tribology indicate that reasonable bionic micro-texture’s surface has a good effect on tool’s anti-friction property. In order to study bionic micro-texture effects on tools’ cutting performance further, in this paper groove and scallop micro-texture are made out on the surface of carbide tool with laser processing technology. Then orthogonal cutting tests are made to cut steel 45 in dry or wet cutting with different feedings. The results show that cutting forces can be effectively reduced by the cutting tool with micro-texture’s surface. Especially, the micro-texture’s tool has the best effect when the direction of grooves is vertical to the direction of chip’s motion, and the wear degree of its rake face is also slighter. All of those will be helpful to guide the design of cutting tool.
