Optimization of Machining Parameters During Dry Cutting of Ti6Al4V Using Taguchi’s Orthogonal Array

Abstract

The present study assessed the effect of control parameter, i.e. approach angle (A), cutting speed (B), depth of cut (C) and feed (D) on the response characteristics, i.e. material removal rate (MRR) and surface roughness (SR) during machining of titanium alloy using Taguchi technique. Experimental trials were performed on the lathe machine using the L9 orthogonal array. Statistical analysis carried out to know the contribution and effect of cutting parameters on response characteristics. From the analysis, it was found that the feed (D) was the most influential factor followed by approach angle (A) which affects the surface roughness (SR) while cutting speed (B) had a most significant effect on the material removal rate (MRR). Subsequently, an optimal control parameter was obtained and modelled for response characteristics.
