Investigation of the Effect of CuO Nanofluid in Minimum Quantity Lubrication Machining

Abstract

Nanofluid is a new class of fluids engineered by dispersing nanometer-size solid particles into base fluids such as water, ethylene glycol, engine oil, cutting fluids, etc. Researches have shown that the thermal conductivity and the convection heat transfer coefficient of the fluid can be largely enhanced by the suspended nanoparticles. Recently, tribology research shows that lubricating oils with nanoparticle additives (MoS2, CuO, TiO2, Diamond, etc.) exhibit improved load-carrying capacity, antiwear and friction reduction properties. These features make the nanofluid very attractive in some cooling and/or lubricating application in many industries including manufacturing, transportation, energy, and electronics, etc. In this study, the effect of CuO nanofluid in minimum quantity lubrication machining was investigated.
