In cutting of aluminum alloys, one of the most serious problems is chip adhesion to cutting tool surface, often leading to tool failure, above all, in dry cutting. To address this problem, we adopted surface engineering approach, namely, a functionalization of tool surfaces by textures. In our previous research, we have developed the DLC-coated cutting tool with nano/micro-textured surfaces and the cutting tool with micro stripe textured surface formed using femtosecond laser technology. Face-milling experiments on aluminum alloys showed that the nano/micro-textured surface suppresses the genesis of adhesion at the atomic level. On the other hand, it was found that micro stripe texture prevents chip adhesion from growing larger even in dry cutting conditions. In this study, a cutting tool with new textured surface combined nano/micro texture and micro stripe texture was developed in order to further improve anti-adhesiveness in cutting of aluminum alloys. As a result, it was confirmed that the combined texture brings excellent anti-adhesion compared to the previously developed tools.

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.
