摘要

This study investigates the influence of laser surface texturing on tool wear evolution, thermal behavior, and cutting forces in high-feed milling of Inconel 718. Comparative analyses were conducted between the non-textured and laser-textured inserts under identical milling conditions. Wear progression was evaluated, revealing that the crater wear and localized notch formation dominate in both cases due to severe thermo-mechanical loading of the interrupted cutting. While both inserts exhibited similar qualitative wear evolution; however, the laser-textured inserts demonstrated reduced wear intensity and a more distributed wear along the rake and flank faces. Additionally, it was shown that the surface texturing significantly amplified the effective flank surface area by approximately a factor of ten, improving convective heat dissipation. The infrared thermography confirmed a substantial reduction in maximum cutting temperature (from ~ 379 °C to ~ 326 °C) for the textured inserts, indicating improved thermal management. Furthermore, the cutting force measurements reveal a more stable force evolution for the laser-textured tool, with reduced growth in axial and radial components, correlating with the corresponding flank and notch wear. These findings demonstrated that the laser texturing effectively modified the wear progression, thermal load, and could stabilize cutting performance.
