Abstract
A combined analytical and experimental study was carried out to investigate the effect of cryogenic cooling on temperature during turning of pure titanium grade-2. Cryogenic machining investigations were carried out by applying liquid nitrogen (LN2) to the cutting zone. The temperature distribution at the machined surface was predicted using a 3D finite element model. An average deviation of 7.42% was noted for the cutting temperature result, and there was good agreement between the simulated and experimental results. The experimental results reveal that LN2 machining improves cooling and lubrication by lowering the cutting zone temperature. Acceptable tool wear, surface roughness, and favourable chip formation are observed in LN2 machining at higher cutting speeds.
