Performance of silver nanofluids with minimum quantity lubrication in turning on titanium: a phase to green manufacturing

Nowadays industries are looking forward for a sustainable manufacturing. Nanofluid with minimum quantity lubrication is one technology in the areas of green manufacturing, which minimizes the pollution caused to the environments. The aim of this work was to examine the influence of silver nanoparticles-based cutting fluid with minimum quantity lubrication in turning on titanium (grade 2) by changing the environmental conditions. Taguchi's L-27 orthogonal array has been selected to execute the experimental trials. The responses considered are surface roughness, temperature and tool wear. The process parameters selected for this analysis were environment, cutting speed, feed and depth of cut. The principal component analysis was used to determine the optimal conditions in turning parameters. It was noticed that environment is the key parameter in defining the responses. Under optimal conditions, the surface roughness has been decreased by 89%, temperature has been reduced by 44% and wear on the tool has also been reduced. The tool wear and chip morphology were reviewed through scanning electron microscope for a complete study.
