| Resumo | |
The present study investigates the effect of texturing the rake face of uncoated cemented tungsten carbide tools by ultrashort laser pulses for tribological improvement. In this sense, four parallel micro-groove texturing patterns were created on the rake face of the cutting tools, beginning at a variable distance from the cutting edge. The pitch between grooves was also varied. Friction force, machining force, chip features, and surface roughness were evaluated from semi-orthogonal dry turning in the reference (non-textured) and textured tools. The results showed friction force reduction by nearly 40%; chip deformation decrease around 21%; machining force reduction by 20%; and surface roughness by 46 and 28% for Ra and Rz, respectively, for the best texturing pattern.
