“…However, MQL gives a significant to reduce the tool wear progression. The existence of mist lubricant from the MQL reduces the cutting force and heat generated from the burnishing and other machining processes [24,26]. Therefore, it decelerates the tool wear progression compared to dry condition.…”

Recently, manufacturing industries have concerned about the utilization of mineral-based metalworking fluids because of the numerous deleterious impacts on the health of workers and the environment as well as the shortage of mineral resources. Due to this scenario, the vegetable-based oils have emerged the researchers’ attention as a suitable replacement for the mineral based metalworking fluids since it is highly biodegradable, low toxicity and renewable resources. Nevertheless, the main problem of the utilization of the vegetable-based oils is that it shows poorer thermal and oxidative stability. The great development technologies had influenced the application of the nanofluids by adding the nanoparticles additives to the base oil as it gives better physical and properties, thus improved the tribological behavior. This study focuses on developing a new green synthesis and formulation of nanofluids from chemically modified jatropha oil by blending with nanoparticles additives such as hexagonal boron nitride (hBN) and graphene at the minimum concentrations (0.01, 0.025 and 0.05 wt.%). The physical testing such as kinematic viscosity, viscosity index and flash point were conducted and compared with commercial synthetic ester (SE). Then, tribological testing was performed by using four ball tribo test and analyses in terms of coefficient of friction, worn surface analysis and surface roughness. From the results, the sample of MJOs had showed an enhancement by providing higher viscosity index. The results demonstrate that MJOg2 provided the lowest coefficient of friction while MJOh3 and MJOg3 had smoother worn surface as it has lowest value of surface roughness in comparison with others sample. It can be concluded that the MJO samples have high potential substitution to mineral-based oil as a sustainable metalworking fluid in machining processes.

“…Next, transesterification process which involved the chemical reaction of JME with TMP (JME:TMP) was conducted in the presence of 1% (wt./wt.) sodium methoxide (NaOCH 3 ) at a molar ratio of 3.5:1 to produce TMP tribostester, which is also known as modified jatropha oil (MJO) [10], [11]. MJO was mixed with hBN and MoS 2 nanoparticles at the concentration of 0.05 wt.% (based on the weight of the oil sample).…”

The development of metalworking fluids has recently shifted the mineral-based oil with vegetable-based oil as a base stock. This is due to the increase of awareness of the society towards environmentally friendly and sustainable criteria, especially in the machining process. Vegetable-based oil from crude jatropha oil is one of the potential candidates to replace the mineral-based lubricant. However, the process of modification for crude jatropha oil needs to be done because the high composition of free fatty acid (FFA) that exhibit to low and undesirable physical properties. This experimental study aims to evaluate the physicochemical properties of newly formulation from modified jatropha-based nanofluids specifically for metalworking fluid with the inclusion of hexagonal boron nitride (hBN) and molybdenum disulphite (MoS 2 ) nanoparticles at a concentration of 0.05 wt%. In this study, the properties of MJO nanofluids were analysed in terms of density, viscosity, water content, acid value and corrosion behaviour according to ASTM standard and comparative analysed with the commercial synthetic ester (SE). The findings of this study shows that MJO+0.05 wt.% hBN (MJOh) exhibited excellent physicochemical properties as it achieved better result for kinematic viscosity at 40°C and 100°C. Additionally, the acid value and water content of the MJOh were the lowest among other samples and excellent corrosion resistant by providing the best microstructure at the workpiece's surface. In conclusion, MJOh has the potential of being a sustainable metalworking fluid for the machining process.
