Analysis and optimization of laser drilling process during machining of AISI 303 material using grey relational analysis approach

Abstract Surface roughness and heat-affected zone (HAZ) are the important features which influence performance of laser-drilled products. Understanding laser process parameters on these responses identifying cutting conditions for simultaneous optimization a primary requirement in order to improve drilling performance. Nevertheless, no such contribution has been made literature during AISI 303 material. The aim present work is optimize surface (R ) HAZ fibre material using Taguchi-based grey relational analysis (GRA). From GRA methodology, recommended optimum combination flushing pressure at 30 Pa , power 2000 W pulse frequency 1500 Hz R HAZ, respectively. variance, identified as most influenced
