Minimum Quantity Cooling Lubrication (MQCL) using nano cutting oil, called NFMQCL, has been a novel solution to bring out the superior cooling and lubricating performance, which is begun to use in machining difficult-to-cut materials. This work aims to investigate the cutting force components in hard milling of Hardox 500 steel with coated carbide tools under MQCL conditions using Al2O3 nano cutting oil. The effects of the nanoparticle concentration, cutting speed and feed rate on the cutting forces Fx, Fy, Fz were evaluated by Analysis of variance (ANOVA) to bring out technical guides for further studies and application. The obtained resuls revealed that the improvement of machinability due to superior cooling lubrication created by NFMQCL environment. The optimal set of input parameters was determined through multi-objective optimization.
