Experimental and Optimization of Parameters on Laser Beam Machining to Minimize Kerf, Surface Roughness and Dross of SS304.

Mechanical Engineering

In conventional machining on laser beam machine, the kerf taper is sizeable and surface roughness isn’t uniform and optimum due to this the quality of workpiece may get affected, which hampered assembly of finished parts. Here we have a tendency to defines there happens a amendment in mathematical values of kerf taper, Kerf width and surface roughness, whereas conducting tests on SS-304 Stainless steel using Nitrogen as assistance gas of CO2 laser cutting. To decide the laser cutting parameter specification so as to widen the material removal rate while at the same time in view of practical process limitation related to dross formation, The laser kerf width and cut edges quality was affect by the process parameters like cutting speed (V), Assist gas pressure level (p) and laser power (P). The experiment was set up and followed on the support of orthogonal array. A prognostic model is create by make use of response surface methodology via ANOVA and and enforced to search out relative influence of process parameters on kerf geometry and surface roughness.
