Soy oil -- Industrial applications; Metal-cutting; Lubrication and lubricants;


Concerns about the long term supply of petroleum, the instability of its prices, and growing environmental issues have led to a variety of legislative and public support for the use of agricultural commodities in industrial applications. This study is of importance because of environmental and health hazards concerns, and the possibility of reducing operating costs with the elimination of disposal of used cutting oil that the use of biodegradable oil offers to the metal-cutting operations.

The purpose of this study was to investigate the effect of the use of an experimental soybean-based oil as a cutting fluid on surface finish for turning operations. The work piece material used was carbon steel 1040. The cutting oils used were Valcool (water soluble metalworking fluid) and soybean based oil. The experiment was developed using a lathe machine and 9 TPG VC5 Valenite indexable carbide inserts. The independent variables for this study were cutting speed, feed rate, and depth of cut, which had to be determined before the experiment started. The dependent variable was the surface finish. The experiment consisted of three cuts using one insert. Each cut had different cutting speed and feed rate values. A total of 27 measurements were made. The data obtained was analyzed using F-test, t-test, and ANOV A test from Microsoft Excel. The results of this study showed that there was no difference with the use of soybean oil when compared to the surface finish obtained with the use of Valcool oil.
