Ultrasonic assisted grinding process with minimum quantity lubrication using oil-based nanofluids

This paper reports an experimental investigation of the vibration assisted grinding process combined with MQL using oil-based nanofluids with MoS2 nanoparticles. Results are presented in terms of normal and tangential forces, force ratio and ground surface roughness. The results show that imposed horizontal ultrasonic vibration significantly decreases the grinding normal force. Also, MQL using nanofluid significantly decreases the grinding tangential force. Finally, simultaneous application of both techniques reduced forces by around 60%, which is very substantial. It also improved the surface quality.
