Waste cooking oil as a bio-cutting fluid in turning operation

Abstract

In this study, waste cooking oil is used as a bio-cutting fluid in a turning operation.  The minimum Quantity Lubrication (MQL) technique is implemented while machining operation.  Aluminium rods are chosen for the surface finish test.  The experiments are conducted on a CNC milling machining and the experiments are performed at different spindle speeds (300, 500, 700 and 1000 rpm) and depth of cuts (0.1 and 0.2).  Furthermore, the waste cooking oil is injected into the workpiece using MQL setup at different pressures (1bar, 1.5 bar and 2 bar).  From the experimental trails, it is observed that at 1000rpm and 0.1 depth of cut, the smooth surface finish is observed for an aluminium rod when compared to dry and other conditions.
