Abstract

Abstract: In this study, an attempt has been made to investigate the influences of cryogenic coolant on cutting temperature, cutting force, thrust force and feed force while turning the Hastelloy C276 – a nickel-based superalloy. Numerical simulation was carried out using Deform 3D analytical tool for the machining process performed at the optimal cutting conditions using Lagrangian formulation. CNC turning experiments were also performed with different cutting parameters. The results observed from the simulation were compared with the experimental investigations and were found to be in good agreement with experimental results. The results inferred that the cutting temperature was reduced up to 57% by involving machining in cryogenic condition. It was concluding from both the simulation and experiment studies that the machining under cryogenic condition effectively reduces the cutting temperature and machining forces when compared with that of dry condition.
