Prediction of Process Parameters in Turning of Titanium Alloys using Response Surface Methodology

Manufacturing of titanium products is difficult because of its machining. The demand for titanium products is increasing rapidly in the applications of surgical components, nuclear reactors, boilers, human in-plants, automobile industries. Because of the inherent properties like high heat resistant, high strength, high chemical reaction with other metals, machining of titanium alloys is always a challenge for manufacturers by using innovative methodology and machining techniques to improve theproductivity of titanium components. The present study is carried out on three different titanium alloys which are used for machining titanium alloys (Ti-Grade2, Ti-6al-4v, Ti-6al-4vELI) with uncoated carbide tools used. Total experiments are performed under dry environment for reducing the cost and optimizing the parameters of surface roughness and cutting force to predict the value design of expert software, ANOVA used. Machining of titanium alloys with uncoated carbide inserts in a dry environment is not suggestible, machining of grade – 5TI-6AL-4V) with uncoated carbide inserts in a dry environment is good and it will deliver better surface roughness and cutting force compared to other two titanium alloys. Optimal cutting conditions are speed 171.59 m/min, feed 0.12 mm/rev, depth of cut 0.70mm titanium (TI-6AL-4V) grade 5, surface roughness 0.647μm, and cutting force 119.182N.
