Abstract: Metal cutting industries are marching towards sustainable ecofriendly manufacturing processes. Nanofluid along with minimum quantity lubrication is the vital combination for sustainable manufacturing. The important objective of this experimental investigation was to evaluate the effect of synthesised monotype (Al₂O₃ and CuO) and hybrid (Al₂O₃/CuO) nanofluid along with minimum quantity lubrication on bearing steel turning by varying the cooling conditions. The response variables surface roughness and cutting zone temperature were selected. For multi-objective optimisation, grey relational analysis technique was utilised to find the optimum condition. Hybrid nanofluid (Al₂O₃/CuO) with minimum quantity lubrication (MQL) cooling condition shown the effective results. The utilisation of Al₂O₃/CuO hybrid nanofluid shown significant minimisation of surface roughness by 66% and 67% compare to CuO nanofluid and Al2O3 nanofluid respectively. Also, effective decrement in cutting zone temperature observed under Al₂O₃/CuO hybrid nanofluid cooling condition by 11% and 10.5% compare to CuO nanofluid and Al₂O₃ nanofluid respectively.
