In the present experimental investigation, the parametric optimization method using Taguchi’s robust design is proposed for Plano milling machining of alloy steel SA387 & mild steel IS2062 with coated cemented tungsten carbide tip tool. In this paper, the effects of process parameters like cutting speed, feed rate and depth of cut have been investigated to reveal their impact on material removal rate and surface roughness. The Plano Milling Machine is used to conduct experiments based on the Taguchi design of experiments (DOE) with orthogonal L9 array. The orthogonal array, signal-to- noise ratio (S/N) and analysis of variance (ANOVA) were employed to find the maximum material removal rate and minimum surface roughness. The experimental results showed that that the optimal combination of parameters for surface roughness are at cutting speed of 250 rpm, feed rate of 1.42 mm/rev, depth of cut of 1.5 mm while for material removal rate are at cutting speed of 400 rpm, feed rate of 1.42 mm/rev, depth of cut of 1.5 mm for material SA-387. The Optimum value of the surface roughness (Ra) comes out to be 2.31 μm. While the optimum value of the material removal rate (MRR) comes out to be 18.8x10 -6 mm 3 /min for alloy steel A387.
