In this study, CNC turning process parameters are optimized while machining AA6061 – T6 alloy. The process variables, namely, cutting spindle speed or spindle velocity (Cs), rate of feed (Fr), rate of the depth of cut (Dc), and nose radius (Nr), were optimized with output responses such as surface roughness (Ra), feed power (Fx), thrust power (Fy), cutting power (Fz), and removal rate of material (MRR). The optimized results showed higher MRR, Fy, and Fz and lower Fx and Ra were obtained at a cutting spindle speed or spindle velocity (Cs) of 100 rev/min, rate of feed (Fr) of 0.2 mm/min, depth of cut (Dc) of 1.5 mm/min, and nose radius (Nr) of 0.8 mm. TOPSIS and ANOVA were used to assess the experimental results to determine the most favourable factors that were superior and suitable for selecting the optimal variable condition.
