Sustainability Analysis of Turning Aerospace Alloy Ti-6Al-4V under Dry, Wet and Cryogenic Conditions

Sustainability of a manufacturing system defines its efficiency and productivity. In the world of ever growing energy requirements and depleting resources the need of sustainability is greater than ever. Present research was undertaken to analyze sustainability of turning aerospace alloy Ti-6Al-4V under different cutting conditions including dry, wet and cryogenic. Feed rate, cutting speed and depth of cut were taken as input variables along with cutting condition. Specific cutting energy was analyzed under varying machining parameters. It was found that energy consumption under cryogenic conditions was lower than dry and wet conditions. At speed of 50 m/min cryogenic turning energy consumption was 9% lower than dry cutting and 16% lower than wet cutting.
