Investigation of grinding performance in ultrasonic vibration assisted grinding of Ti-6Al-4 V alloy using minimum quantity lubrication

Minimum quantity lubrication (MQL) is an efficient cooling and lubrication technique usually used these days in grinding operation. It is found to be advantageous for improving the grinding performance in terms of reduced grinding forces, surface integrity and production cost since it offers better cooling, lubrication, and lower coolant consumption. Ultrasonic vibration assisted grinding (UAG) has also shown the improvement in the grinding performance owing to the change in the nature of cutting process in UAG. In this study, the grinding performance of UAG combined with MQL using soluble oil on Ti-6Al-4V alloy is studied through surface grinding experiments. The results show significant improvement in surface finish and reduction in grinding forces are achieved in UAG with MQL grinding process as compared with conventional dry and ultrasonic vibration assisted dry grinding.
