Potential of Various Metal-Oxide Nanofluids for Sustainable Machining Application—A Review

The machining process is widely used to manufacture various machine elements for its innumerable application in manufacturing industry. The cutting fluid imparts an essential duty to the machining processes as a coolant and lubricant. With the advancement and innovations in the machining processes, the cutting fluid is under progression, and many novel cutting fluids are developed in last two decades. In recent years, the metal-oxide and non-metal-oxide particle-based nanofluids have drawn attention of the researchers due to their enhanced thermophysical and tribological properties and capabilities as efficient coolant and lubricants. This article reviews the work on potential use of the metal-oxide-based nanofluids for sustainable machining processes reported in the scientific literature over years.
