Development of Palm Kernel Oil Coolant as an Alternative to Soluble Oil Coolant

Abstract

This work presents the development of cutting fluid from local materials (palm kernel oil). The developed cutting fluid from local materials will be compared with the soluble oil. This comparison will be made on the basis of surface finish of the work piece after machining using both cutting fluid. Generally, there are be a few type of cutting fluid in the market and the application of cutting fluid to the machining process will give a few advantage such as producing a good surface roughness etc. the main purpose of this project is to investigate the performance of palm kernel oil application as a cutting fluid in machining operation especially turning operation. The experiment will be conducted using mild steel materials as work piece. Two work piece of equal materials (mild steel) with equal dimension will be turn on the conventional lathe machine using palm kernel oil prepared into cutting fluid as coolant in the turning of one of the work piece, and the soluble oil as the coolant use in turning the other work piece. The cutting parameters used were cutting speed 335rpm, feed rate 0.5mm/rev, and depth of cut is 0.5mm. These entire parameter tester tests will be kept constant throughout the turning operations. Surface roughness value will be taken for each work piece through the surface roughness, this value will represented in graphs and chart, which will show the surface roughness against cutting speed for palm kernel oil (PKO) cutting fluid, cutting surface roughness against cutting speed for soluble oil. The variation of the surface roundness of the work piece (mild steel) at different cutting speed palm kernel oil (PKO) coolant, also differentiating cutting speed for soluble oil coolant. Palm kernel oil performed very well the specific function of soluble oil as cutting fluid which include good chip formation, reduction of heat generation and realization of a good surface finish. The surface roughness value of the work piece will increase with decrease in speed and vice-versa.
