Abstract—Recent machining processes have increasingly focused on the application of Minimum Quantity Lubrication (MQL) nanofluid. This research specifically explores the remarkable performance of nanofluid in the hard milling of SKD11 steel. A well-organized series of experiments was conducted to examine the effects of various cutting fluids, including dry machining, MQL, and nanofluid-based MQL, as well as cutting parameters such as cutting speed, depth of cut, and feed rate, on surface roughness, cutting force, and cutting temperature. The Taguchi method and Analysis of Variance (ANOVA) were applied to determine the optimal values for cutting fluids and cutting parameters. The research findings indicate that to achieve the minimum surface roughness and cutting force, the cutting conditions should be performed with a cutting speed of 80 m/min, a depth of cut of 0.2 mm, a feed rate of 0.01 mm/tooth, and the application of MQL nanofluid as the lubrication condition. The conditions to minimize the cutting temperature are a cutting speed of 40 mm/min, a depth of cut of 0.2 mm, and a feed rate of 0.01 mm/tooth. In addition, the findings also demonstrate the significant efficacy of MQL nanofluid in enhancing surface roughness, diminishing cutting force, and decreasing cutting temperature during the hard milling process of SKD11 alloy steel.
