ABSTRACT:- Minimum quantity lubrication is a technique to have the advantages that cutting fluids bring yet keeping their use at minimum. Signify MQL and MQL with nanoparticles was selected in this study as the cutting fluid for turning of steel (SS 316L). The hard turning was at various cutting speeds (100, 150, and 200 m/min) and feeds (0.1, 0.15, and 0.2 mm/rev) and depth of cut (0.4, 0.6, 0.8) take place. The machining responses were surface roughness, and cutting forces . Design of experiments was applied to quantify the effects of cutting parameters to the machining responses.Empirical models surface roughness, and cutting forces were developed within the range of cutting parameters selected. Box-Behnken technique was used to decide no. of experiments. Analysis of variance (ANOVA) was performed to determine the significance parameters at a 95% confidence interval. All machining responses are significantly influenced by the cutting speed, feed, depth of cut and also MQL with nanoparticles.
