Minimum quantity lubrication (MQL) has gained significant attention in various research fields and industrial applications for its advantages of being environmentally friendly and suitable for sustainable production. The effectiveness of MQL is increasing significantly by using nano cutting fluid, which can be produced by suspending nanoparticles in the based cutting fluid. This study aims to investigate the effects of MoS2 nanoparticle concentration, cutting speed, and feed rate on MQL hard turning of 90CrSi steel in terms of surface roughness and surface microstructure. The Box–Behnken experimental design was used to analyze the influence of input parameters and their interaction effects as well as to find the optimal set of variables. The obtained results prove the improvement of the machinability of carbide tools due to higher cooling and lubricating performance created by MoS2 nanofluid MQL, which contributes to improve the surface quality and reduce the manufacturing cost. There is an interaction effect between nanoparticle concentration and feed rate which has a strong influence on surface roughness.

“…Consequently, droplet velocities are maximal at the spray axis and decrease in the radial direction due to interaction with the surrounding air. However, it was found that the effective MQL spray angle (φ eff ) is 10°-12° of the spray cone angle (φ) around the spray axis, at flow rate of 90 ml/h and 6 psi air pressure (Park et al 2008). Within the spray angle of approximately 10°-12°, multiple droplets have been agglomerated.…”

Tool wear is a natural phenomenon in all metal cutting operations due to high friction at tool work interface, which affect the tool life, product quality and accuracy of work. For minimizing the friction at tool work interface the cutting fluids or lubricants are used for cooling and lubrication, hence improvement in machining efficiency. But if the quantity and quality of lubricants are unattended or underestimated then it creates problems like soil, water, environmental pollution and also makes the machining process uneconomical. The different cooling and lubrication techniques have been developed today. So it is necessity of present day scenario of machining to work with technology which would not degrade the environment, face the competition and have better quality of products. Different research shows that conventional Flood lubrication is limited by health hazards, misting and sometime uneconomical as compared to other techniques, due to its high discharge rate of fluid. These problems have been overcome by using dry machining. Studies shows that dry machining also becomes non efficient and uneconomical during cutting of harder materials at higher cutting speed, feed and depth of cut, although it is environmental friendly and economical at particular machining level. So to minimize all these Problems of health hazards, non-economy, intense tool wear in case of flood cooling and dry machining, the minimum quantity lubrication (MQL) has been applied in this present research. The effect of varying the nozzle stand-off distance and lubricant pressure have been considered in this study, to find out the best results in terms of cutting temperature. The experimentation has been conducted during turning of EN-31 Alloy Steel with minimum quantity lubrication at flow rate of 150 ml/hr having vegetable based oil. The temperature has been measured by K-type thermocouple .The vegetable oil has been selected due to its environmental friendly behavior and does not produce health hazards, like mineral oil during flood lubrication.
