Lubrication is prime requirement of metal cutting industries to assure high quality performance. A lot of heat developed because of high friction during an abrasive material removal process. The conventional method of cooling consumes high amount of coolant but still insufficient to control thermal related problems. The proper penetration of coolant is not possible and most of the fluid goes in waste form. This method is uneconomical and eco-friendly less. The alternative is minimum quantity lubrication technique, in which a minute amount of lubricant with high air velocity delivers directly to cutting zone for effective penetration. The nanofluids have excellent convection heat transfer and thermal conductivity properties. To reduce the excess usage of grinding fluid, nanofluid has recently applied to grinding process using minimum quantity lubrication technique. The MQL based nanofluid technique (nanofluid MQL) gives better cooling and lubricating effects which improves overall grinding performance compared to conventional flooded, MQL and pure nanofluid machining. This literature study provides a review on results obtained for grinding process in different grinding environments. It helps to find the research gap for the researchers to develop green and sustainable grinding process for better results.
