Abstract :Challenges in machining Ti-6Al-7Nb titanium alloy have forced researchers to investigate new advanced machining methods. In this study, the effects of dry and minimum quantity lubrication (MQL) cutting conditions on the cutting forces and cutting temperature in conventional and ultrasonic vibration assisted turning of Ti-6Al-7Nb alloy were investigated experimentally and numerically. Ultrasonic vibration assisted MQL (UVA-MQL) method provided improvement in cutting performance compared to all other methods in terms of cutting force and cutting temperature. The experimental results and numerical results were in good agreement and the underlying reasons for the improved cutting mechanism were revealed

Keywords :Finite element analysis, Minimum quantity lubrication, Ti-6Al-7Nb, Ultrasonic-vibration assisted cutting.
