This paper presents the use of soybean as an alternative to soluble oil in machining a mild steel material. A detailed comparison of soluble oil and soybean oil as coolants was carried out. The coefficient of correlation (r) of soybean oil when computed was found to be 0.5, a value that fall in the range of moderate correlation. The performance of the coolant-lubricant was evaluated from its effects on mild steel. In this regard the performance of soybean oil was found to be moderate and may, in the alternative, be used as a cutting fluid.
Keywords: Coolant, Lubricant, Machining and correlation.
