This paper presents the pulsed laser cutting behavior of an Al-Li/SiC metal matrix composite. SEM and EDX examinations were conducted to study the influences of laser cutting parameters on the quality of the machined surface. Through proper process control it was found possible to minimize the heat affected zone (HAZ) and to improve the quality of the machined surface. An empirical formula relating the width of the HAZ and the laser cutting parameters was proposed. Furthermore, a theoretical model has been successfully applied to predict the maximum depth-of-cut for the composite. Finally, the optimum condition for achieving high cutting efficiency with minimum material damage was recommended.
