Abstract: This study examined effect of nanofluid minimum quantity lubrication (NF-MQL) with CuO nanoparticles on Inconel 718 machinability. During turning process tribological properties (surface roughness and tool wear) and chip morphology were analysed. Minimum quantity lubrication (MQL) setup was used during turning process. L18 orthogonal array was used to conduct experimental trial. Nanoparticle size, flow rate, weight % and cutting speed used to analyse tribological properties along with chip morphology. Experimental results shows that cutting speed, particles size and flow rate are significant variable for a surface roughness and tool wear. Abrasive and chipping off wear mechanism was observed. For surface roughness 78.54 m/min cutting speed, 23 nm particle size, 0.3 wt. percentage and 160 ml/hr flow rate are the optimum conditions whereas for tool wear 78.54 m/min cutting speed, 8 nm particle size, 0.2 wt. percentage and 120 ml/hr flow rate are the optimum conditions.

Keywords: Inconel-718; CuO; nanoparticles; roughness; wear; chip; morphology; NF-MQL.
