This article presents an integrated multi-criteria decision making using Entropy, MOORA and COPRAS methods for turning Nimonic C263. Experiments were performed under L27 Taguchi orthogonal array. Dry turning was performed and cubic boron nitride (CBN) was used to turn the alloy. The variables speed, feed and depth of cut were chosen as factors. For each experiment, the shear force component was measured during on line. The insert flank wear was measured after every experiment. The main objective of this paper is to identify the suitable trial to ensure minimum force and flank wear simultaneously. Because of the cost reduction and quality improvement, the controlling factors level should be selected appropriately. Hence, the integrated MCDM technique using MOORA, COPRAS and Entropy was chosen to determine the best experiment out of 27 experiments. Alternatives were ranked and the results were evaluated. The best experiment for minimization of force and flank wear is found to be 125 m/min, 0.055 mm/rev and 0.25 mm. The experimental test were observed with lesser deviation and confirmed that proposal found is more suitable to obtain minimum force and flank wear.
