During excessive fluid application processing, fluid ends up on the floor, the workers, and the machine, entail serious techno-environmental and biological problems. Very little fluid enters the tool/part interface. Recently, this excess fluid has become another costly control problem. Chemicals of all types introduced into the atmosphere must also be reduced to an absolute minimum. In this paper, the technique of minimum quantity of lubrication (MQL), which is the pulverization of a minimum volume of oil in a flow of compressed air, has been studied in face mill Ti-6Al-4V titanium alloys as one alternative to the use of abundant cooling to suppress the cutting heat resulted from low thermal conductivity and the density of the workpiece material. The results showed that MQL of 125ml/h flow amount was found to be the optimum, and there is no significant difference in temperature between MQL of this flow and wet cooling when low cutting speeds used.
