Experimental and Optimization of Process Parameters on Laser Beam Machining to Minimize Kerf taper Surface Roughness and Dross formation of SS 304

Abstract

newlineLaser machining is a common industrial technique used to inexpensively cut a variety of newlinematerials. SS304 laser machining is examined in this work. Laser kerf width and cut edge quality newlinewere affected by process parameters i.e. cutting speed (V), assist gas pressure level (p), and laser newlinepower to be able to determine how to set laser cutting parameters in order for the material newlineremoval rate can be increased while accounting for practical process limitations associated with newlinedross formation (P). For optimization, a statistical approach known as quotResponse Surface newlineMethodologyquot (RSM) is applied. Using RSM, the effects of control factors (laser power, cutting newlinespeed, and assist gas pressure) and categorical factors (ferrous and non-ferrous material) were newlinestudied for different responses (surface roughness, Dross formation, kerf taper for straight newlineprofile) using An analysis of variance, also known as an ANOVA, was conducted with the newlineintention of ascertain relevance of the operating parameters on the performance qualities that newlinewere being taken into account There have been further tests conducted to validate the execution newlineof optimal parameters. The appropriate set of process parameters has been selected following the newlinediscoveries made in this study. To test the impact that each parameter has on surface roughness, newlineDross formation, kerf taper, an ANOVA was carried out. Finally, the confirmation test to newlinecompare the projected value of wear rate to the experimental value has been conducted. newlineKeywords: CO2 Laser cutting, ANOVA, RSM, Kerf Geometry, Laser cutting parameters
