Metal cutting operation is one of the manufacturing industries operations that can benefit tremendously from the application of nanofluids as coolants. Nanofluid is one of the recent inventions in the field of Nanotechnology. Nanofluids can be simply thought of as fluids prepared by the suspension of nanoparticles (1 – 100 nm) in a base fluid. This is done in order to improve the thermophysical properties of the base fluid as regards it intended application. However, from available literature research as shown that nanofluid does have improved thermophysical properties compared to other fluids under same application as well as positive effect on the machining parameters. In addition, there is still the need for standardization in it mode of preparation, percentage by volume of its inclusion in the base fluid, nanoparticle size and it application. Therefore, this paper presents some recent experimental investigation on the use of nanofluids as coolants in metal cutting operations.
