Microtexturing for enhanced machining: Evaluating tool performance in laser-processed cutting inserts

Abstract

This study explored the significance of microtexturing on cutting tools to improve tribological performance and reduce friction in machining operations. Drawing inspiration from biomimetic structures, this study focuses on laser surface microtexturing and evaluates its impact on the cutting forces and tool wear. Experiments involved the microtextures of dots with a specific emphasis on a fiber laser-processed pattern. While long-term tests reveal the formation of negative protrusions on textured tools, reduced variability in cutting forces suggests potential benefits for stable machining processes and increased tool longevity. These findings underscore the intricate relationship between microtexturing patterns and tool performance, offering insights into the broader implications of energy-efficient machining.
