In view of green manufacturing, dry machining has drawn much attention from industries recently. Remarkable improvement on tool coating technology has facilitated the complete elimination of cutting fluid in some machining processes. In most applications; however, the cutting fluids are still required due to the high friction and adhesion tendency between work and tool materials and the difficulty of chip and heat removal [1–3]. Therefore, in some applications, an optimal solution for lubrication condition can be found between dry machining and flood cooling. In this regards, minimum quantity lubrication (MQL) is a viable solution to overcome the disadvantages of both dry and flood cooling machining processes.
