A Review On Optimization Of Machining Parameters For Surface Roughness In Turning Operation Of Titanium Alloy.

Abstract

Titanium alloy is a high specific strength material and it has excellent mechanical characteristics such as high stiffness, high strength-to-weight ratio, exceptional corrosion resistance and hardness at high temperature, so it is being increasingly employed in various fields such as automotive, aerospace and bio-industry. For machined product, the productivity and the quality are the main important challenges of metal cutting or in production industry during turning processes and inherent characteristics of titanium alloy promote poor surface roughness, heat dissipation from the tool workpiece interface, rapid tool wear. This results in competing manufacturing industries to sustain in the market field. This article reviews the optimization parameters such as cutting speed, depth of the cut and feed rate for the turning operation of titanium alloy and focuses on the analysis of  process details. This study also investigated the machinability of titanium using coated and uncoated carbide tools and the different optimization methods and their related analysis software. The results show the significant improvement in surface roughness, tool life and other evaluating parameters.
