The present study investigates the effect of hybridization of two different nanofluids (alumina and molybdenum disulphide) in turning of AISI 304 stainless steel. The hybrid nanofluid was prepared by mixing alumina-based nanofluid with molybdenum disulphide (MoS2) nanoparticles in a fixed volumetric proportion of 90:10. The prepared base fluid (Alumina nanofluid) and hybrid nanofluid in various nanoparticle concentrations of 0.25, 0.75 and 1.25vol.% have been tested for their thermophysical properties at different temperatures. Furthermore, pin on disc test, and contact angle measurement of all the nanofluid samples was conducted to examine their tribology and wettability, respectively. The Response Surface Methodology (RSM) was used to design the experiment for turning. The regression models were developed and experimentally validated for all the three components of machining forces and surface roughness. The machining performances of hybrid nano-cutting fluid are compared with that of alumina-based nanofluid in terms of machining forces and surface roughness. The use of Al-MoS2 hybrid nano-cutting fluid has shown a significant reduction of 7.35%, 18.08%, 5.73%, and 2.38% respectively, in cutting force (Fz), feed force (Fx), thrust force (Fy) and surface roughness (Ra) compare to Al2O3 mixed nanofluid.
