摘要

This study provides a thorough comparison of the dry turning performance of hardened AISI D3 tool steel, using laser-textured and uncoated carbide inserts. The intent of this study was to investigate the effects of surface- texturing on selected performance metrics (flank wear and surface finish) depending on cutting conditions. Micro-dimples were created through a nanosecond-pulsed Nd: YAG laser on the rake face of the inserts to improve the tool-chip interface performance. The machining parameters were optimized using a Taguchi L9 orthogonal array design employing statistical analysis to quantify each input parameter’s effect on tool wear and surface finish. The present study shows laser-textured tools reduce flank wear and surface roughness compared with standard tools. Overall, this study shows that laser surface texturing has great potential as a sustainable, lubrication free approach to machining difficult to cut materials such as D3 steel.
