Abstract
This research shows with superior lubricating, heat-conducting properties, and proper market price, Al2O3 and MoS2 nanoparticles have broad application prospects as lubricant additives. This work has been researched, and most researches are restricted to using one kind of lubricants to machine specific workpiece or multiple workpieces. There has been no systematic and detailed analysis of grinding performances from cutting mechanisms and debris formation mechanisms of different workpieces. Therefore, analysis of signal to noise ratio(S/N), variance, microstructure, and morphology analysis were used to study the influence of different typical nanofluid lubricants on the grinding performance of different materials in this chapter. Results showed that the optimal grinding parameters are using nodular cast iron and MoS2 nanofluid. Compared with other lubricants, MoS2 nanofluid can exert a significant effect on reducing wear of grinding wheel. In order to reduce surface roughness, MQL lubricating oils of the following sequence can be used: Al2O3 nanofluid, MoS2 nanofluid, and pure palm oil.
