Surface roughness and surface damage analysis of titanium alloy (Ti6A14V) in high speed turning process using refrigerator air as coolant

Abstract

Recent developments and chaos on climate change has led to researchers and scientist’s world over to rethink and bring impactful changes to the current manufacturing processes. Current manufacturing trends require large usage of cutting fluids for lubrication during machining. This leads to increase the cost of production in industries. Also due to some harmful additives present in cutting fluids for better lubrication effects, are polluting the environment and leading to affect the health of operator during machining. With the aim to reduce the effect of cutting on environment, Refrigerated Air as Coolant has been adopted by various machining and grinding applications. In this work, the high speed turning of Titanium alloy (Ti6Al4V) is carried out using refrigerated air as a coolant. In order to maintain a good surface integrity and to improve the machinability of Ti6Al4V experiments were conducted by varying different machinability variables. The machinability variables such as speed and feed rate were varied and its influence on surface damage and surface roughness were measured and analyzed.
