Abstract

Abstract: This project defines there occurs a change in mathematical values of surface roughness (Ra, μm) and Kerf width (Kw, mm), while conducting experimentation of CO2 laser cutting on SS-304 Stainless steel using Nitrogen as assistance gas. The laser kerf width and cut edges quality was influenced by the process parameters like cutting speed ( V ), Assist gas pressure ( p ) laser power ( P ). The experiment was constructed and followed on the base of L27 orthogonal array. A predictive model is generated by using multiple regression analysis through ANOVA and implemented to find relative influence of process parameters on Kw and Ra.
