Abstract

Abstract: Stainless steel is an important engineering material that is difficult to be cut by oxy-fuel methods because of the high melting point and low viscosity of the formed oxides. However, it is suitable to be cut with help of laser. The objective of this work is to do parametric analysis of process parameters for fiber laser cutting system on surface characteristics of the cut section in the cutting of 3 mm Stainless Steel (SS) sheet (ASTM 304). In this study, the laser cutting parameters such as laser power, cutting speed and gas pressure were analyzed and optimized with consideration of workpiece surface roughness and top kerf width. Design of experiments (DOE) technique was implemented to analyze all three parameters. It was observed that the laser power had more effect on responses rather than cutting speed and gas pressure.
