Optimization of the radial cutting force in turning operation of inconel718

In this paper, the Taguchi method is used to optimize the Radial force in Turning Operation of Inconel 718 using Carbideinsert with PVD (Physical Vapor deposition) coated of TiAlN and TiN. The process parameter, cutting speed, feed rate, and depth of cut, have been selected for investigation. Experiments were conducted on the basis of Taguchi’s L9 orthogonal array. The Signal to noise ratio (S/N ratio) and the analysis of variance ANOVA (general linear model) are applied to optimize the effects of the selected process parameters on Radial force. The results show that speed is the most influencing factor followed by depth of cut and feed. The confirmation experiments validate the results of the findings.
