Abstract
The current research paper is focused on investigating the influence of Laser beam machining process parameters on surface roughness and kerf width of HSLA steel. Taguchi’s L18 orthogonal array is adopted to conduct the machining studies. MOORA method is used to evaluate the suitable combination of the LBM process parameters. The combined effect of machining performance measures is analysed using analysis of variance to identify the significance of the result. Consequently, the influence of the parameters on machining responses were explored. The surface morphology of the machined surface of the optimal set of parameters has been studied.
