This paper deals with the optimization of turning process parameters of Aluminum alloy 7075 using Taguchi methodology. The cutting parameters considered for the study are feed rate, cutting speed, and depth of cut, with two different tool noses to get minimum surface roughness. The type of insert used was a tungsten carbide, while the coolant was soluble oil performed at 150mL/hr. Taguchi orthogonal array (L9) using nine experimental runs are designed for machining. The results show that the optimum parameters of machining are obtained at a feed rate of 0.3mm/rev, cutting speed 900rpm, depth of cut 1.0mm in the case of nose radius (0.8mm), and a feed rate of 0.5mm/rev, cutting speed 900rpm, depth of cut 0.5mm in the case of nose radius (1.2mm). Confirmation tests with the optimal levels of cutting parameters were done to illustrate the effectiveness of the Taguchi optimization method. Taguchi method is found to be a very efficient tool to obtain an optimum surface roughness.
