Performance of Liquid Nitrogen (LN2) on Machining Pure Titanium (Grade 2): A Comparative Study
Year: 2024
Type: article
Abstract: The biggest challenge for manufacturing industries is machining super alloys due to their properties. Titanium grade 2 also comes under the category of difficult cut material. In this present investigation, the green manufacturing technology was applied to cut the titanium grade 2. The comparison study was carried out between dry and cryogenic machining. The turning trails were performed using TiN-coated carbide cutting tools. Cutting force measurements surface roughness as well as the tool wear studies were carried out with the Kistler dynamometer, SURFCOM and SEM analysis. From the responses, under cryogenic cooling 32.5% of main cutting force reduction was observed when contrasted to dry condition at a cutting speed of 282 m/min. The 24 % of improved surface quality was observed under cryogenic cooling approach, more fracture on tool rake face was observed under dry condition and the favorable chip formations were also noted under cryogenic cooling approach.
