“…As stated by Yahaya and Samion, 2 CMFO is fully formulated lubricant, and may demonstrate sluggish movement during forging processes. As a consequence, friction and compression force seem to be reduced during the transition period and metal-to-metal contact between the die and the work material was minimal.…”

“…Friction is one of the key factors for evaluating the tribological performance of palm oil in metal forming process. Zhang et al, 16 has proposed the used of two friction model that is Coulomb friction factor (CFC) as presented in equation ( 1) and Tressa shear factor (TSF) represented equation (2).…”

“…According to Hassan et al, 1 there is a huge amount of pressure to decrease or eliminate the usage of nonrenewable substances, such as mineral-based oils, since they are a substantial source of environmental pollution and have the potential to affect the health of employees. Besides that, as stated by Yahaya & Samion, 2 Scholars are working to develop a replacement lubricant that can meet or exceed the performance of mineral-based lubricants as demand for mineral oils drops. Metal forming procedures, especially cold work processes, need the use of lubricant in order to prevent tool wear, increase tool life, and enhance surface polish.…”

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.

“…Moreover, owing to poor formability of aluminium and aluminium alloys at room temperature, friction tests of alloys focus on plastic working in warm and cold forming conditions. Yahaya and Samion [ 31 ] analysed the friction condition of AW-6061 aluminium alloy lubricated with bio-lubricant in a cold forging test. It was found that the palm oil-based lubricant has good performance compared to a mineral-based oil in terms of surface roughness.…”

Aluminium alloy sheets cause many problems in sheet metal forming processes owing to their tendency to gall the surface of the tool. The paper presents a method for the determination of the kinematic friction coefficient of friction pairs. The determination of coefficient of friction (COF) in sheet metal forming requires specialised devices that ‘simulate’ friction conditions in specific areas of the formed sheet. In this article, the friction behaviour of aluminium alloy sheets was determined using the strip drawing test. The 1-mm-thick 6082 aluminium alloy sheets in T6 temper were used as test material. Different values for nominal pressures (4.38, 6.53, 8.13, 9.47, 10.63, and 11.69 MPa) and different sliding speeds (10 and 20 mm/min.) were considered. The change of friction conditions was also realised with several typical oils (hydraulic oil LHL 32, machine oil LAN 46 and engine oil SAE 5W-40 C3) commonly used in sheet metal forming operations. Friction tests were conducted at room temperature (24 °C). The main tribological mechanisms accompanying friction (adhesion, flattening, ploughing) were identified using a scanning electron microscope (SEM). The influence of the parameters of the friction process on the value of the COF was determined using artificial neural networks. The lowest value of the COF was recorded when lubricating the sheet metal surface with SAE 5W40 C3 engine oil, which is characterised as the most viscous of all tested lubricants. In dry friction conditions, a decreasing trend of the COF with increasing contact pressure was observed. In the whole range of applied contact pressures (4.38–11.69 MPa), the value of the COF during lubrication with SAE 5W40 C3 engine oil was between 0.14 and 0.17 for a sliding speed of 10 mm/min and between 0.13 and 0.16 for a sliding speed of 20 mm/min. The value of the COF during dry friction was between 0.23 and 0.28 for a sliding speed of 10 mm/min and between 0.22 and 0.26 for a sliding speed of 20 mm/min. SEM micrographs revealed that the main friction mechanism of 6082-T6 aluminium alloys sheet in contact with cold-work tool steel flattens surface asperities. The sensitivity analysis of the input parameters on the value of COF revealed that oil viscosity has the greatest impact on the value of the COF, followed by contact pressure and sliding speed.

“…It also goes by the name of palm olein and is most frequently used as cooking oil. Palm oil can be used as an industrial lubricant due to its longer hydrocarbon chain and low unsaturation (Yahaya and Samion, 2022). The number of unsaturated fatty acids and the length of the fatty acid chain both have an effect on the viscosity of palm oil.…”

Purpose The purpose of this study is to investigate the use of micro-pits technology to the problem of tribological performance in a sliding motion. Design/methodology/approach Vegetable oil is a sustainable and economically viable alternative to both mineral and synthetic oils, offering significant savings in both the cost of research and manufacturing. To solve the depriving issue and boost lubrication film thickness, the micro-pits on the surface may function as reservoirs that provide the oil to the contact inlet area. In this research, an aluminium block is used as the workpiece material in an evaluation of a through pin-on-disc tribotester. Lubricating oil in the form of super olein (SO) was used in the experiment. Findings The results show that the friction performance during a rubbing process between a hemispherical pin and an aluminium block lubricated with SO using aluminium alloy materials, AA5083, was significantly improved. Originality/value In this study, a material that breaks down called SO, which is derived from the fractionation of palm olein, was used to use a modified aluminium micro-pit sample that will serve as a lubricant reservoir in pin-on-disc tribotester.
