Parametric Optimization on Multi-Objective Precision Turning Using Grey Relational Analysis

The quality of a machined surface is becoming more and more important to satisfy the increasing demands of sophisticated component performance, longevity, and reliability. The objective of this paper is to analyze the performance of precision turning of using conventional lathe on Ti-6Al-4 V under dry working conditions. Various parameters that affect the machining processes were identified and a consensus was reached regarding its values. The proposed work is to perform machining under the selected levels of conditions and parameters and to estimate the, cutting temperature and surface roughness generated as the result of the machining process. Based upon the experimental values, Analysis of Variance (ANOVA) was conducted to understand the influence of various cutting parameters on, surface roughness, cutting force, tool ware and cutting tool temperatures during precision turning of titanium alloy. Optimal levels of parameters were identified using grey relational analysis, and significant parameter was determined by analysis of variance.
