Impact of Single and Duplex Cryogenic Jets on Mechanical and Physical Characteristics in Turning of Titanium Superalloys

Abstract:

This analyses evaluates the cutting force , surface roughness, chip morphology, chip–tool interface temperature, tool life, and Single use of a coated carbide tool and double liquid nitrogen jets for friendly superalloy that is extremely difficult to cut being turned (Ti-6Al4V). The rake face was the only focus of the single jet, while the rake and flank surfaces were concurrently hit by the duplex jets. Liquid nitrogen jets provided the highest machining quality, reducing cutting force , temp, hardness, and, apparently, tool life. When equated to dry and single jet assist, the double liquid nitrogen jets increased life of the tool by 60% and 30%. In spite of this, chip manufacture has not changed. Using duplex liquid nitrogen jets to extend tool life, reduce tool costs, lower temperatures, improve surface quality, and most importantly, promote machinability of Ti-6Al-4V superalloy has been accepted as a sustainably booster.
