Effects of hybrid Al2O3–CuO nanofluids on surface roughness and machining forces during turning AISI 4340

Abstract This paper presents an effort to model the process parameters involved in turning of alloy steel AISI 4340 workpiece material with Al 2 O 3 and CuO hybrid nanofluids using minimum quantity lubrication (MQL) method. In this paper, effect mixing two nanoparticles (Al CuO) different weight percent environmentally friendly water-based cutting fluid, rotational speed, feed rate has been investigated on surface roughness machining forces response The results experiments show that nanofluid containing 0.75 0.25 best output for roughness. Also, composition (0.75 ), lowest value achieved at a 0.08 mm per revolution speed 1000 rpm as well 710 rpm.
