Abstract

The use of cutting fluids during machining operations creates several occupational health risks and many environmental effects as well. However, it is important to reduce the environmental burdens without sacrificing the production rate and product quality. Among various techniques to achieve these goals, the minimum quantity lubrication (MQL) technique has shown promise as an environmentally friendly machining process. Previous investigations suggest that the rake and flank faces of the cutting tool undergo different types of interactions between the tool and workpiece materials. The tribological and thermofluidic phenomena occurring at these two places are quite different. The rake face generates more heat, and the resulting tool wear is responsible for catastrophic failure of the tool. On the other hand, wear at the flank face is more responsible for the surface finish.
