Abstract
Nowadays, the use of lubricant in metal forming processes using vegetable oil is highly desired because it is a renewable resource and has a high biodegradability relative to mineral oil. Non-renewable resources, such as mineral oil, have been widely used from the outset because of its ability to act as a reservoir to the wearing contact that functions as a film material or supports chemical transformation into a film material. This article is highlighting the use of refine bleached and deodorized (RBD) palm stearin as a bio lubricant in ring compression test by benchmarking with unlubricated sample and Daphne oil using annealed aluminum AA6061 as a workpiece material. The test undergoes four different formation that is 10, 20, 30 and 40% at room temperature, that will be compare to finite element method, to predict the friction of each test. From the result obtain, palm stearin has improved the Tresca shear friction (m) from 0.4 to 0.3, but when compare to Daphne (0.25), RBD Palm stearin has higher shear friction. From the wear observation, it shows that RBD palm stearin has a very high in surface roughness value (about 7.4%) when compare to the Daphne oil.
