A Review on Study the Methods and Applications of MQL using Natural Oils

In the present study it has been surveyed that, the metal industries using the cutting fluid has become more problematic in terms of employees health and environmental pollution. Micro lubrication are also known as minimum quantity lubrication (MQL) serves as an alternative to fluid cooling by reducing the volume of cutting fluid used in the machining process; but not significant health concerns. In the present day to diminish the negative effects associated with the cutting fluids, researchers have developed new bio based cutting fluids from various vegetable oils. MQL machining was performed much superior in cutting zone temperature enabling favorable chip formation and tool wear, with enhanced the tool life and surface finish. This review paper present the effects of minimum quantity lubrication (MQL) by vegetable oils based on the lathe performance of low alloy steel as compared to completely dry and wet machining in terms of tool wear, surface finish and surface roughness.
