A short review on hybrid nanofluids in machining processes

In every conventional machining process interaction of tool interface with that of workpiece results in high temperatures and thermal distortions. Such distortions may lead to change in the surface morphology of the machined workpiece, thus harming the desired finishing of the product. The use of nanofluids as a coolant over traditional cutting fluid help in minimising such problems. In continuation to the past research on nanofluids, the use of hybrid nanofluids in machining operations is attracting the researchers. The synthesis of hybrid nanofluid is done by dispersing two different nanoparticle in traditional heat transfer fluid which can be seen as efficient coolant and lubricant. The hybrid nanofluids are found favourable in terms of thermo physical properties, heat transfer rate and stability. This has led to increase in research on hybrid nanofluids over mono type nanofluids. This paper summarises the application of hybrid nanofluids by various researchers in different machining operations namely turning, grinding, and drilling. Furthermore, the paper deals with the tribological properties of different hybrid nanofluid and the temperature control in the machining operations.
