Abstract

The simplest machining method for eliminating undesired material from a workpiece using a single point cutting tool is turning. Appropriate cooling and lubrication save production lead time, machining costs, and environmental impacts controlled by cutting fluids. The impact of cooling cum lubrication techniques, such as minimum quantity lubrication with typical cut-ting fluids, minimum quantity lubrication with nanofluids, and minimum quantity lubrica-tion with hybrid nanofluids, on turning performance metrics were thoroughly reviewed. The effect of these cooling solutions on results, such as cutting temperature, cutting force, surface roughness, tool wear, and chip morphology, has been extensively reviewed and addressed in the literature. Moreover, the nanoparticle types, size, concentration, base fluid types, and lu-brication for nanofluid and hybrid nanofluids with minimum quantity lubrication have been considered during the study. The review of the relevant literature indicates that outcomes are significant. The impact of these cooling solutions on cutting temperature, cutting force, sur-face roughness, tool wear, and chip morphology has been thoroughly examined and addressed in the literature. The review of relevant literature indicates that outcomes are significantly improved when minimum quantity lubrication with nanofluids and hybrid nanofluids is con-trasted with alternative cooling techniques. It is possible to reduce substantially pressures, cut-ting temperatures, surface roughness, and tool wear. Different kinds of nanoparticles, particle size, concentration, and nozzle inclination angle are the most critical factors in optimizing heat transfer rate and minimizing tool wear. Aluminium oxide (Al2O3) is the most commonly used nanoparticle in minimum quantity lubrication applications involving nanofluids and hybrid applications because it forms a coating between the workpiece and cutting tool contact, reducing friction. Additionally, the coefficient of friction significantly slowed. In addition, the minimum quantity lubrication with nanofluids also improves the colour and shape of the chip’s morphology.
