“…It has been demonstrated that JO exhibits better tribological properties than other bio-oils, for example, rapeseed oil [10] and is compatible with different sealing elastomers from fuel and lubrication systems [22,23,24]. It has also been reported that the frictional coefficients are reduced by blending JO with mineral oils for different applications, namely, hydraulic fluids [25], engine oils [14], metal working fluids [26,27], automatic transmission fluids [28], drilling muds [29], etc. Negligible changes in terms of wear have been reported by using low percentages (<20%) of JO in blends with mineral oils [14].…”

Bio-lubricants have emerged as a potential and viable way to replace, totally or partially, mineral oils due to their effectiveness in the boundary lubrication regime for different applications, including, automotive engine operation. However, the effect of thermo-oxidation caused by the long-term use of the bio-lubricants on their tribological properties has been scarcely analyzed. In this work, the effect of thermo-oxidation of Jatropha oil (JO), an engine mineral oil (EMO) and a blend made up of 80%vol. EMO and 20%vol. JO (B20) on the tribological behavior of a simulated piston ring/engine cylinder liner interface was studied in reciprocating friction tests at 26 and 100°C. The oils were thermally oxidized and characterized in terms of carbonyl compounds, depletion of ZDDP additives, changes in kinematic viscosity and viscosity index. Friction coefficients, wear rates and scar morphologies were assessed. Thermo-oxidation resulted in significant viscosity increases in JO compared to EMO and B20. Also, it generated increased friction coefficients for JO and B20. However, they were lower than those for fresh and aged EMO. EMO increased the wear rate after thermo-oxidation in contrast to JO. Smearing was generated using most oil samples while severe scuffing was only produced by using fresh JO at 100°C.

“…Noticeable point is that viscosity has significant influence on heat transfer and energy ratio coefficient. Talib and Rahim [67] chemically modified crude jatropha oil to trimethylopropane ester (modified jatropha oil) and proved that this modified oil be a substitute of synthetic ester in MQL. In another research, Talib and Rahim [68] added hexagonal boron nitride (hBN) in different percentages and achieved better machining performance from modified jatropha oil with 0.05%wt.…”

Various types cooling/lubrication techniques are used in machining processes for enhancing machining performances. Conventional way of cooling/lubrication requires higher coolant cost, waste and disposal cost. Not only has that it had many negative impacts on environment and operators health. For attaining highest efficiency of cutting fluids with minimum quantity, different sustainable strategies are tried to develop. In recent decades researchers are worked out on different cooling/lubrication strategies alternative to conventional cooling. This paper represents a comprehensive review of all presently practiced cooling/lubrication strategies and their effects on different aspects such as surface quality of machined component, tool wear, tool life, cutting temperature, cutting forces etc. through analyzing selected papers. The influence of different cutting fluids such as solid lubricants, nanofluids, ionic liquids etc. with their positive and negative impacts is also discussed. The research gaps are also identified for further research works. From review it is clear that the machining performance is highly affected by cooling techniques and coolant types. Selection of proper cooling technique with suitable cutting fluids depends on work material, tool material and cutting variables.

“…A vegetable oil such as palm oil consists of a high percentage of unsaturated fatty acid in the carbon chain. Unsaturated fatty acids contain double bonds which are easily broken with high temperature [9]. This enhances the formation of high lubrication strength film on the tool-chip or tool-workpiece interface.…”

Metalworking fluid acts as cooling and lubrication agent at the cutting zone in the machining process. However, conventional Metalworking fluid such mineral oil gives negative impact on the human and environment. Therefore, the manufacture tends to substitute the mineral oil to bio-based oil such as vegetables and synthetic oil. In this paper, the drilling experiment was carried out to evaluate the efficiency of palm oil and compare it with minimal quantity lubrication technique using synthetic ester, flood coolant and air blow with respect to cutting temperature, cutting force, torque and tool life. The experimental results showed that the application of palm oil under minimal quantity lubrication condition as the cutting fluid was more efficient process as it improves the machining performances.
