Improving Tool Wear Resistance in Steel Cutting by Textured Surface and its Mechanism

Abstract

In the cutting processes, improvements of anti-adhesive properties and wear resistance of cutting tools are strongly required for increasing a cutting tool life. In order to meet these requirements, we adopted surface engineering approach, namely, a functionalization of tool surfaces by textures. In our previous researches, we have developed two types of cutting tool with textured surface, namely, cutting tool with nano/micro textured surface and cutting tool with micro stripe textured surface, in the hopes of improving anti-adhesive properties in cutting of aluminum alloys. As a result, we have clarified that the developed tools significantly decrease chip adhesion on the tool surface by a series of face milling experiments for aluminum alloys. In this paper, the previously developed tools with textured surfaces were applied to the cutting of steel material (S53C) and the wear resistances of the textured surfaces were evaluated. As a result, it was found that the micro stripe texture improves the wear resistance significantly. Moreover, the mechanism of improving wear resistance by the textured surface was also discussed.
