• In this research work the commercially available powder form of alumina (Al2O3) and colloidal solution of silver (Ag) nanoparticles were mixed with water to prepare the nanofluids (NFs) of different concentrations. The prepared NFs have been used under MQL mode during the machining of nickel based alloy. The results obtained with NFs have been compared with biodegradable emulsion and dry machining. The small contact angle, more spreadability and tiny droplets size of alumina NFs provided reduced cutting forces, tool wear and chip curling during machining. The phenomenon of tribo-film formation has also been observed with alumina NFs which protected the rake face. Further, the nano-ball bearing effect of silver NFs resulted in good surface finish and reduced abrasion wear. •Alumina and silver nanoparticles were mixed with water to prepare the nanofluids.•Nanofluids have been used under MQL mode during the machining of Ni based alloy.•Non-machining experiments have been conducted to study the droplet distribution of the fluids.•Machining with nanofluids provided better results as compared to other conditions.
