However, extreme heat generated during turning process affects the surfaces of the material. Hence there is an absolute need for a suitable cutting fluid which eliminates the heat produced in the machining areas. This work intends to examine the performance of silver nanofluid-assisted minimum quantity lubrication (MQL) in turning D3 tool steel. This article aims to analyze the surface roughness, chip morphology, cutting temperature, tool wear, microhardness, residual stress, and microstructure of the machined surfaces under various machining conditions (machining environments, cutting speed, depth of cut, and feed rate). Machining environments include nanofluid MQL, oil MQL, and dry cutting. Results indicate that the performance of silver nanofluid significantly influences in minimizing the tool wear, cutting, temperature, surface hardness, and surface roughness consistently comparing with dry cutting and oil MQL. The nanofluid MQL outperformed among the other cooling–lubrication methods in terms of techno-environmental aspect to improve sustainability. Hence, application of silver nanoparticle into cutting fluid can be competently and productively utilized for machining of die tool steel under ecologically cognizant minimum quantity cooling–lubrication, which is the most accepted in industrial applications.
