Cutting force is a remarkable indicator in machining because of its influence on tool strength, machining system vibration, and machined surface quality. In this study, response surface methodology (RSM) was applied to build a predictive model of cutting force in hard milling of SKD 11 steel. The cutting parameters (cutting velocity, depth of cut and feedrate) and SiO2 nanoparticle concentration (wt%) were experimentally investigated to find out their influence on the output response. Empirical data were analyzed using a statistical analysis of variance (ANOVA). The results show that a cutting mode including higher cutting velocity, smaller feedrate and smaller depth of cut under MQL nanofluid conditions (with 4wt% nanoparticle) will achieve the minimum cutting force. In addition, efficiency in cutting force reduction of nanofluid MQL was demonstrated when compared with conventional MQL.
