Machinability Study in Turning of Ti-6Al-4V under CO2-based Vortex Tube Cooling System

The study on the machinability of titanium alloys provides new ways to minimize difficulty levels machining due substantial heat accumulation. To improve machinability, pivotal factors such as accumulation and cutting temperature must be regulated. In this study, a turning operation was performed Ti-6Al-4V reduced by supplying cooled CO2 gas through vortex tube connected with two nozzles. Variations in force, temperature, surface roughness speed, feed, depth cut were recorded. Subsequently, responses compared for single nozzle tube, dry, compressed air environments at different speeds. Cutting force followed similar trend which increased decreasing increasing feed cut. all three variables. proposed cooling system provided better results terms roughness, while marginally higher observed dry
