摘要：In this paper, the multi response optimization studies of titanium alloys have beenanalyzed by Response Surface Methodology (RSM) and Finite Element Methods (FEM).The cutting speed, feed and depth of cut are taken as input parameters and surfaceroughness, vibrational amplitude, elastic recovery, cutting forces and tool wear have beenconsidered as machining characteristics/responses of the end milling of Ti-6Al-4V. Thedesign of experiments follows the orthogonal array of L27 to perform experiments atthree levels of cutting speed, feed and depth of cut. Two fluted tungsten carbide end millsare used in machining of titanium alloy. The process parameters are optimized for smallervalues of surface roughness, amplitude of cutter vibration, cutting forces and tool wearand larger values of elastic recovery. In this work, numerical simulation is also carriedout to study the machining characteristics for all the experiments. Interaction effect of theprocess parameters on the responses is also studied. These experimental and numericalvalues have been correlated. This analysis is used in online tool condition monitoringwhich improves productivity, machining time and tool life.
