Abstract
The results show that the nanofluids with a volume fraction of 2% have good comprehensive properties for lubrication. However, this study only concentrates on workpiece material—nickel base alloy. Based on literature analysis, researchers have carried out a large quantity of researches on NMQL grinding of different workpiece materials including hard steel HSS, quenched steel 100Cr6, nickel base alloy, Ti-6Al-4V alloy, soft steel CK45, and cast iron. They have mainly focused on grinding force, surface roughness, etc. The heat transfer state of nanofluids is neglected, and the research on the heat transfer mechanism of grinding temperature is lacking. Therefore, grinding temperatures obtained through MQL grinding with different concentrations of vegetable oils-based nanofluids as well as their heat transfer mechanism are investigated through simulation and experiment in this chapter.
