One of the promising solution to improve the hard machining performance is the application of Nanofluid Minimal Quantity Lubrication (NF MQL). The presence of nanoparticles not only improve the cooling lubrication of the based cutting oil but also create more lubricating mechanisms in the cutting zone. This paper aims to study effect of MQL using nano cutting oil on the hard milling process. The Box-Behnken experimental design was utilized to investigate the effects of input variables on the responses. The obtained results indicated that the concentration of nanoparticles, cutting speed and feed rate cause the strong influences on the surface roughness and cutting forces. Also, the appropriate ranges of input variable values can be determined for the required outputs. Moreover, the better cooling and lubricating effects were reported and the machinability of carbide inserts was improved by using Nanofluid Minimal Quantity Lubrication.
