Abstract: Investigating the cooling and lubrication effects of MWCNTs-based nanofluids with surfactants in reducing cutting force and surface roughness compared to dry and wet is the main focus of this study. Besides this, searching out the optimal settings of process parameters including cutting speed, feed rate, depth of cut, and cutting environment in milling Ti-6Al-4V alloy is another prime objective. Box-Behnken design (BBD)-based response surface methodology was employed for experimental design. To predict the chosen responses, quadratic models were developed. Analysis of variance (ANOVA) results showed that the cutting environment has the highest significance, with a variation in cutting force and roughness of about 76.5% and 49.9%, respectively. Both responses were lowered significantly in nanoMQL over wet. Optimisation using the composite desirability approach results that 32 m/min cutting speed, 22 mm/min table feed, 0.75 mm depth of cut, and NanoMQL were the optimal solution within the selected boundary constraints.
