“…The surface roughness at 40% deformation the NA-O has the lowest value of the surface roughness that is 0.543 μm and PS has the highest value of surface roughness of 1.905 μ m. PKO has shown a better performance in surface roughness (0.588 μ m) compared to the benchmark lubricant CMFO at 0.782 μ m. The result of the surface roughness also shows that the effect of different viscosity is not a main concern, as CMFO that has a highest viscosity at room temperature still cannot improve the surface finish of the ring. This result however has a different finding from the previous study by Nurul and Syahrullail (2016) that propose the extruded billet of PS surface roughness has better performance compared to PKO in extrusion test. The test of PMO in metal forming is one of the new approaches of palm oil-based (Rasep et al , 2021) and from the result obtained PMO has a lower surface roughness (0.663 μ m) when compared to the PKO.…”

Purpose Cold forging operation is one of the widely used techniques in industry production. This paper aims to present a case study in highlighting and modelling the use of different type of palm oil-based [palm stearin (PS), palm kernel oil (PKO) and palm mid olein (PMO)] as a bio-lubricant in cold forging process using experimental and finite element method. Design/methodology/approach Ring compression test plays a fundamental role in the understanding of materials science and engineering because of the deformation, friction and wear behaviour. Aluminium (A6061) was used in this test to observe the deformation of the ring with different palm oil and its derivatives by comparing with commercial metal forming oil. Findings The presence of certain type of palm oil-based lubricant has a good performance compared to mineral-based oil in terms of surface roughness but when observed in terms of friction the result shows that palm oil-based lubricant has poor friction performance compared to mineral oil-based lubricant (m = 0.25), where PS has the lowest friction at m = 0.3 compared to PKO (m = 0.35) and PMO (m = 0.38). Research limitations/implications This research is using palm oil in cold forging test to study the friction, formation and stress at certain levels of stroke. The detail of the test is explained in the manuscript as attached. Social implications This research is trying to promote the use of biodegradable material to reduce pollution to the surrounding. Originality/value The originality of this paper has been checked using Turnitin and the result is 13%.

“…According to Nurul and Syahrullail (2016), the lower force recorded in using commercial metal forming oil may be owing to additives used in the industry added which enhances fully developed film layer during compression. PS however shows good potential as a metal forming lubricant with the load only slightly higher when compared to the CMFO.…”

“…From their research, palm oil based has potential to be utilize as metal forming lubricant, where the friction coefficient of palm oil based is somewhat lower compare to the mineral oil based [112]. This finding has been proved by Nurul in 2015 and where it shows that palm stearin has better performance compare to VG 460 and VG 95 (viscosity grade mineral oil) [113][114]. At room temperature, RBD palm stearin exists in a semi-solid state, and it completely transforms into a liquid at 40°C.…”

From their research, palm oil based has potential to be utilize as metal forming lubricant, where the friction coefficient of palm oil based is somewhat lower compare to the mineral oil based [112].…”

Due to its low scrap, high production rates, and higher yield strength of cold-formed products following forming operation, cold metal forming methods stand out as the most beneficial method of metal forming. The use of metal forming process is one of the major aspects in manufacturing process and the utilised of lubricant is extremely vital. When referring to lubricants, the term "bio-lubricant" refers to a stock that is both renewable and biodegradable. Fats and oils, which are derived from fatty acids, may be reacted with alcohols to create esters. It is crucial for the economy, people, and the environment that lubricants be developed and used efficiently. For this article, we scoured the literature and analyzed the most up-to-date research on the topic of metal forming process improvement and the use of vegetable oil as a metal forming lubricant. This research intends as a case study and demonstrating the tribological analysis in metal forming process and the potential of using bio lubricant in the metal forming. Future manufacture of new oil blends from new and conventional oil sources will be offered to the market for a variety of economic and health concerns.
