Nano fluids constitute the blending of nano sized (<100 nm) metal and non-metallic grains in traditional cutting fluids. Due to the extensive thermal and tribological properties, nano fluids are preferred for high heat transfer applications. Therefore, the amalgamation of nano fluids in base cutting fluids creates interest to researchers. This paper focuses on summary of different research works conducted on nano particles blended in cutting fluids. Authors have facilitated the functioning mechanisms of various nano particles blend with traditional fluids. Also, the effect of these fluids was analyzed in various machining process like turning, drilling, milling etc. As evident from literature survey, the better surface finish and excellent lubrication were obtained by adding higher concentration of nano particles in base cutting fluids. This is due to the surface improvement effect (mending and polishing) and direct effect (rolling, filming, and sliding) of cutting fluids. Also, the nano fluids are used to decreases the nodal temperature, cutting force, tool wear, power consumption and coefficient of friction. Authors have also found the research gaps for future research.
