Taguchi Analysis on Cutting Forces and Temperature in Turning Titanium Ti-6Al-4V

Abstract

Titanium alloy machining is hindered basically due to its high chemical reactivity and low thermal conductivity. The present work is focused on investigating the effect of process parameters on machinability performance characteristics and there by optimization of the turning of Titanium (Grade 5) based on Taguchi method. The cutting speed, feed and depth of cut were used as the process parameters where as the cutting force and temperature ware selected as performance characteristics. The L9 orthogonal array based on design of experiments was used to conduct experiments. The degree of influence of each process parameter on individual performance characteristic was analyzed from the experimental results obtained using Taguchi Method. The cutting speed was identified as the most influential process parameter on cutting force and temperature.
