Optimization and Investigation of Effect of Laser Beam Machining (LBM) Process Parameters on C-45 Steel Material”

Laser machining is a popular manufacturing process utilized to cut various types of materials economically. In this paper laser machining of Mild Steel has been investigated. Mild Steel is soft because of its high strength and malleability LBM is a precise and efficient manufacturing route in many applications. In the present research, Taguchi Method was used for analysis of effect of LBM process parameters on surface roughness (SR) on C-45 mold steel material. Different parameters like gas pressure, laser power and cutting speed are used to optimize surface roughness by MINITAB 19. Taguchi orthogonal array L9 along with ANOVA is used for optimizing three different parameters so that minimum surface roughness is obtained. Keywords: LBM, Taguchi Method, ANNOVA, SR.
