Abstract

Vegetable oils (palm oil, groundnut oil, shear butter oil and cotton seed oil) have been used as lubricants in the turning operation of aluminum under varying spindle speeds, feed rates and depths of cut and the results compared with kerosene (due to the gummy nature of aluminium metal). The parameters investigated are the chip thickness ratio, surface finish and surface temperature. Their performances when compared with the conventional soluble oil have shown that they can perform the same functions as imported ones in the machining of aluminum. They reduced chip thickness ratio, improved surface finish and exhibited good cooling behaviour at the work piece-tool interface. This performance is due to their high viscosities and the presence of surface active agents such as stearic acid and halogens, such as chlorine which help to reduce surface energy of a liquid and increase its wetting ability or oiliness.
