“…This could cause debris to become trapped inside the lubricant, which would then generate a higher surface roughness at 4.2 s and above. According to Farhanah and Syahrullail, 13 palm oil-based lubricant has a greater surface roughness owing to the creation of the soap layer that squeezed out later during the pressing of the contact surface. This causes the surface to have a more uneven texture.…”

“…High viscosity oil was able to give higher oil layer thickness, that generates significant flow resistance and makes protecting the mating surface difficult. 13,18 Similarly, when the oil viscosity is too low, it may be effective in the border lubrication regime but is readily wiped off during sliding action on the contact surfaces.…”

“…Previous research into the development of PMO as a bio lubricant has been limited in contrast to that of Palm olein, PKO, and PS. 10,11,13 In addition to this, early observations of the physicochemical properties of PMO (see Table 1) revealed that the lubricant has the potential to be used as a bio-lubricant due to the fact that it contains free fatty acid. According to Aiman and Syahrullail, 14 free fatty acid is thought to have the ability to reduce friction.…”

In the past, most metal-forming lubricants used mineral oils or other hazardous compounds as their primary foundation. Due to their non-toxic and biodegradable qualities, vegetable oils have the potential to replace mineral oil as a lubricant. Palm oil's byproduct is presently being researched as a biolubricant in order to expand its market beyond cooking oil. Modeling a finite element approach is one of the excellent predictions in tribological tests, notably in metal forming processes. The purpose of this paper is to serve as a modelling the metal forming process and demonstrate the use of palm mid olein as a biolubricant. The metal forming test is essential to the understanding of materials and engineering research because of the friction, wear behaviour, and deformation it produces. Utilizing aluminum (AA1100) as a specimen, this study compared the results of using palm oil-based metal forming oil to those of using commercial metal forming oil. In order to better understand the forging process, we analyse the material flow patterns of these parts at different die stroke levels. According to the findings, the friction of both tested experiment is slightly different where in ring compression test (RCT) test palm mid olein (PMO) has a higher friction ( m = 0.20 and μ = 0.0937) compare to commercial metal forming oil (CMFO) ( m = 0.15 and μ = 0.075) but in closed forging test, the friction PMO has found to be lower ( m = 0.39/μ = 0.159) compare to the CMFO ( m = 0.42/μ = 0.1675). From the investigated result also, PMO has a potential to be utilized as a metal forming lubricant.
