Abstract
In this study, it has been examined that cutting fluids are used in different machining operations to improve machining characteristics. The cutting fluids reduce tool wear, enhance surface quality of the work-piece and reduce cutting temperature. It also helps in carrying away the unwanted chips produced during machining. On another side, the cutting fluids have numerous harmful effects. These fluids causes skin and lungs disease to the operator and it is very difficult to dispose. Because of this kind of harmful effects, a lot of research work has been recently reported towards minimizing the use of cutting fluids or to totally avoid them. Recently, Minimum Quantity Lubrication (MQL) has come into existence as an alternative to conventional cooling. The process mainly focuses on the use of minuscule level of lubricants mixed with pressurized air and sprayed on to the cutting zone through the help of nozzle. This review paper shows the effect of MQL on the machining performance of different workpiece when contrasted with dry machining and flood cooling in terms of temperature, chip morphology, surface roughness and tool wear.
