Validation of cemented carbide tools textured by ultrashort pulse laser through surface and force measurement under honing-like conditions

Abstract

In this study, pyramid shaped abrasive-like protrusions were produced on four different cemented carbide tools by an ultrashort pulse laser. These pyramids mimicked the geometric and dimensional features of abrasives exposed on honing tools. Interaction between the abrasive protrusions and workpieces were tested under honing-like conditions. Results regarding the wear of the individual abrasive protrusions were assessed in Fang (2021) by different microscopes, including scanning electron microscope (SEM). In this paper, results with respect to workpiece change (mass, diameter, roughness, and chips) and force development were presented. The findings validated the similarity of the textured tools to the reference honing tool B151. It is also found that the overall performances of the textured tools differed within the four carbide grades, mainly depending on their hardness. Hard tools were more likely to maintain the shape of abrasive protrusions due to their low wear, and they achieved more material removal on the workpieces with less roughness reduction, and higher tangential force coefficients (TFC), compared to the soft tools.
