Although ceramic particles in Titanium Metal Matrix Composites (TiMMCs) improve its wear resistance properties, they also cause high abrasive tool wear. In an attempt to enhance tool life and productivity, Laser Assisted Machining (LAM) of TiMMC was performed under different cutting conditions, an aspect that has never been investigated before. Analysis of the results showed that LAM can significantly increase tool life by up to 180%. The phenomenon of improved tool life at higher speeds and under LAM conditions were explained through the analysis of the chip morphology and micro-structure. (C) 2011 CIRP.
