Effect of Gas Based Coolant Lubricants on Machinability of Titanium Alloy Ti6Al4V

Abstract:

Machining of titanium alloys generates enormous amount of heat at the chip-tool interface leading to poor machinability. Use of coolants in the form of gas based lubricants is another approach for controlling the temperature at the cutting zone. The current research investigates the effect of gaseous cooling using CO₂ and cryogenic cooling using LN₂ at the tool rake face during machining of Ti6Al4V. The effect of both the cutting environments was analyzed at low and high level of cutting conditions through FE Model highlighting on thermal softening and through the experimental output responses emphasizing on cutting forces, surface finish and chip microstructure, etc.
