Experimental Study of Ultrasonic Vibration Assisted Turning Titanium Alloys with Nanofluid MQL
摘要
Abstract
By combining the ultrasonic vibration assisted cutting with nanofluid MQL,ultrasonic vibration assisted turning experiments were conducted for titanium alloys with different vibration di-rections and cutting speeds.The synergistic mechanism among diamond,graphene,diamond/gra-phene composite nanofluids and ultrasonic vibration was analysed.The results show that all modes of ultrasonic vibration may reduce the main cutting force and increase the compressive residual stress,but the ultrasonic vibration in depth of cut direction may enlarge surface roughness.During the ultra-sonic vibration assisted cutting,graphene nanosheets may generate interlayer shear effect and enhance heat transfer,thus reducing the cutting forces,decreasing the values of surface roughness,and in-creasing the compressive residual stresses.The dominant effects of diamond nanoparticles are scratc-hing and polishing under the conditions of high-speed cutting and vibrations in feed direction,which may reduce the values of surface roughness of Ra to 50％.Diamond/graphene composite nanofluid ex-hibites balanced performances and reduces the main cutting force and surface roughness than that of palm oil in all three cutting modes,namely the speed-depth of cut direction elliptical ultrasonic vibra-tion-assisted low-speed cutting,the speed-depth of cut direction elliptical ultrasonic vibration-assisted high-speed cutting and the speed-feed direction elliptical ultrasonic vibration-assisted cutting.The maximum reductions of main cutting force and Ra were both larger than 20％.关键词
