ABSTRACT
The cutting fluid plays a vital role by cooling and lubricating the cutting tool-workpiece interface and washing away the chips from machining zone. The conventional fluids may possess good lubrication properties, but poor thermal properties exhibited by them restrict their use as a cutting fluid for commercial purpose. The spreadability of all the cutting fluid samples were investigated on goniometer. The wettability characteristics of any cutting fluid can be determined by the measurement of the contact angle between the solid surface and the droplet. The determination of contact angle is often based on Young’s contact angle equation. The hybridization of Molybdenum disulphide (MoS2) nanoparticles with alumina nanofluid has shown significant improvement in terms of tribological and machining performance. The mixing of alumina and MoS2 in a fixed volumetric ratio enhanced its tribological and machining performances. However, the optimization of mixing proportion may further enhance its performances.
