Experimental investigation of ultrasonic vibration-assisted cryogenic minimum quantity lubrication for milling of Ti-6Al-4V and grinding of Zerodur

Abstract Increasing demands on component properties are leading to the development of high-performance materials for which conventional production methods reaching their limits from an economic and ecological point view. In recent years, two technologies have been developed that show great potential compared machining processes, particularly in such as titanium alloy Ti-6Al-4V. Ultrasonic-assisted leads reduced cutting forces increased tool life. Cryogenic minimum quantity lubrication prevents occurrence high temperatures allows higher material removal rates without a negative impact This paper shows influence ultrasonic-assisted milling grinding processes combination with cryogenic machinability high-strength Ti-6Al-4V Zerodur. The investigation addressed forces, wear, surface roughness. superposition resulted longer life lower wear both grinding. However, roughness was consistently due ultrasonic superposition. Nevertheless, vibration-assisted has difficult-to-machine materials, especially reduction wear.
