In order to improve anti-adhesive properties of cutting tool surfaces in cutting of aluminum alloy, we adopted surface engineering approach, namely, a functionalization of tool surfaces by textures. In our previous research, we developed a DLC-coated cutting tool with nano/micro textured surface using femtosecond laser technology and face milling experiments on aluminum alloys shows that the DLC coated nano/micro-textured surface significantly promoted anti-adhesiveness at the tool-chip interface. In this paper, the anti-adhesiveness of the previously developed cutting tool was evaluated in detail and we designed new textures of a cutting tool surface based on a mechanism for the formation of the chip adhesion in cutting of aluminum alloy. As a result, it was found that the newly developed tool having micro stripe textured surface shows an excellent anti-adhesive property both in wet and dry cutting of aluminum alloy without any coating technologies.
