Abstract
The investigation focuses on the validation of nano-coated tool insert with various controlled cutting parameters under different coolants in the turning Ti-alloy. A cutting of aerospace grade-5 alloy has the inherent ability to produce an elevated cutting temperature. During turning operation, it not only damages a tool insert but also damages the surface finish of the workpiece. The regular commercial cutting fluid is inadequate for controlling the wear mechanism and cutting temperature. The wet and cryogenic coolants were used in turning Ti-alloy. The effect of cutting parameters on machining temperature, main cutting force, and surface roughness was identified using optimization of multi-response TOPSIS method. From TOPSIS, the optimized cutting parameter was at cutting velocity (135 m/min), at depth of cut (0.5 mm), and at feed rate (0.102 mm/rev). The tool wear and surface roughness also were analyzed. The results show the AlCrN nano-coated insert under cryogenic (LN2) coolant was better compared to other conditions.
