Abstract:
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.
