Effectiveness of Vegetable Oil based Nanofluids in Machining of Steel

Abstract

The present work illustrates formulation of coconut oil based nanofluids with nano boric acid (nBA) dispersions. These nanofluids are utilized in machining as cutting fluid to test their viability. Experiments are performed in turning AISI 1040 steel under dry, conventional cutting fluid(CCF) and nanofluid. Cutting forces, cutting temperatures, tool wear and surface roughness are measured under varying cutting conditions. It is seen from the results that vegetable based nanofluids has greatly improved the machining performance compared to other lubricating conditions. Simulation work is done in order to carry out a comparative analysis between experimental and simulation results. The reduction in cutting forces and cutting temperatures were found to be far better than the conventional cutting fluid. Thus the coconut oil based nanofluid is found to be effective in the utilization of machining both as lubricant and coolant.
