Process Parameter Optimization of Laser Beam Machining for SS-304

This paper presents an investigation and optimization of process parameters of laser beam machining process on SS-304. LBM uses the light energy from a laser device for the material removal by vaporization and ablation. In the present study, attempt is made to find the optimal machining conditions with Taper (T) and surface roughness (Ra) as objective. It was observed that with increase in laser power, taper and surface roughness increases. Response surface methodologies D optimality test was used to determine the optimal machining parameters, among which the laser power and the cutting speed were found to be the most significant. It was observed that lower laser power and cutting speed is suitable for better taper and surface roughness.
