Abstract
In the present work, a hybrid modular machining technology was designed for machining of Ti6Al4V alloy. Ultrasonic machining was integrated with vortex tube based spot cooling system with CO2 gas as working fluid for achieving the cumulative advantage of both, which is termed as Spot Cooled Vibration Assisted Turning (SCVAT). Its performance is evaluated and compared with Conventional turning, Vibration Assisted Turning and Vortex tube based spot cooling under constant machining conditions. The vibration and cooling parameters were also kept constant wherever applicable. The results showed a significant reduction in cutting temperature (30.98%), surface roughness (65.97%), and tool wear (75.03%); however, cutting forces are increased slightly compared to dry cutting. Compressive surface residual stresses were generated on the machined surface in SCVAT.
