Optimization of process parameters during turning of Inconel 625

Abstract

Abstract One of the important machining technology is high speed machining, It is used for difficult to machine materials like nickel base alloy, titanium etc. For grinding process important alternative is came in to consideration is hard turning process. In this study, high speed turning operation is carried out on Inconel 625. Inconel 625 material is nickel base material which is having good corrosion resistance, heat resistance alloy etc. It is majorly used in chemical processing, oil and gas industry, nuclear power plant, submarine manufacturing industry. Because of high strength and several work hardening tendency it is difficult to machine. High speed machine of Inconel 625 and other Inconel alloy is severally used in machining of power plant equipment, aerospace components, sub-marine parts etc. The main objective of this experimentation is to examine and observe on response parameter like cutting forces and surface roughness on input parameter such as cutting speed, feed rate and depth of cut. Experimentation was conducted as per Taguchi’s L9 orthogonal array during turning operation. The results are analyzed using analysis of variance (ANOVA) method. This analysis shows the percentage contribution of parameters.
