Abstract : This paper investigates the optimization of surface roughness (Ra) in the CNC turning of AISI 4041 low-alloy steel using a Taguchi design and advanced Analysis of Variance (ANOVA). A Taguchi L25 orthogonal array was utilized to evaluate the individual and interactive effects of spindle speed, feed rate, and depth of cut. Experimental data were analyzed via signal-to-noise (S/N) ratios alongside a General Linear Model (GLM) ANOVA utilizing Type III sum of squares to isolate factor contributions.

Keywords : Surface Roughness; Taguchi Method; ANOVA; CNC Turning; Feed Rate; Optimization; AISI 4041 low-alloy Steel.
