Super alloy, Inconel 718 is widely used in sophisticated applications due to its unique properties designed for the engineering applications. Due to its peculiar characteristics machining of Super alloy Inconel 718 is difficult and costly. The present work is an attempt to make use of Taguchi optimization technique to optimize cutting parameters during high speed turning of Inconel 718 using tungsten carbide cutting tool. Taguchi method is a powerful Design of Experiments (DOE) tool for engineering optimization of a process. It is an important tool to identify the critical parameters and predict optimal settings for each process parameter. Analysis of variance (ANOVA) is used to study the effect of process parameters and establish correlation among the cutting speed, feed and depth of cut with respect to the major mach inability factor, cutting forces such as cutting force and feed force. Validations of the modelled equations are proved to be well within the agreement with the experimental data.
