Abstract: Ultrasonic vibration assisted turning with nanofluid minimum quantity lubrication (UVAT-NMQL) has proven to be an effective means of improving the processing property. To further understand the tribological mechanism of different types of nanoparticles at the cutting zone, four types of nanofluids were employed in the UVAT-NMQL processes of titanium alloy. The results indicate that the carbon nanotubes, with a one-dimensional tubular structure, can exhibit the adsorption filling effect and a similar effect to rolling bearings, effectively reducing the main cutting forces. High-hardness three-dimensional nanoparticles (alumina and diamond) also function similarly to rolling bearings, but they are more susceptible to being squeezed into the machined surface. Graphene and molybdenum disulphide, with two-dimensional lamellar structures, easily spread on the workpiece surface and contribute to friction-reduction through interlayer shear behaviour.
Keywords: UVAT; ultrasonic vibration assisted turning; minimum quantity lubrication; nanofluid; titanium alloy.
