Tribological behavior of textured tools in sustainable turning of nickel based super alloy

Abstract In this research study, textured tools were fabricated and used for machining under different cooling conditions. The most important uniqueness of the work lies in the use of textured tools for machining Inconel-718 under dry, Nitrogen cooling and nanofluids (hBN mixed with minimum quantity lubrication) conditions. In the turning experiments, two different level of cutting speed i.e., 75 and 125 m/min and a constant level for feed rate (0.1 mm/rev) and depth of cut (0.5 mm) were considered. The above three conditions were tested and compared with and without the use of textured tools. The tool wear, surface roughness, cutting temperature, micro-hardness of machined samples and chip morphology were investigated under these subjected conditions and at turning parameters. The results demonstrated that the nanofluids with textured tool provide the superior results in comparison with other cooling conditions. These results establish textured tools as a sustainable alternative to the existing cutting tool technology being used in the manufacturing industry.
