Performance and evaluation of vegetable oil-based fluids as future cutting fluids in turning of duplex stainless steel

Abstract

This experimental study article analyses the machinability of Duplex Stainless Steel when turned using various wet coolants, including as (Coconut, Mustard, Soyabean oil). Cutting speed, feed, depth of cut, nozzle inclination angle, pressure, and standoff distance are all input process factors. The output response parameters were considered such as thrust force, machining zone temperature, tool wear and surface roughness. In this experimental study, Taguchi technique was used to design the experimental runs under three different level combination of process parameters. The experimental result indicates that the turning performance has been improved at coconut oil condition over the other coolant conditions and it produces the uniform surface finish throughout the length of the workpiece.
