| Summary: | Most lubricants used for machining industry are mineral-based oil thus gives negative impact on environment
and humans because of their toxicity and non-biodegradability. Therefore, vegetable-based oil has been taken as other
initiatives to produce bio-based metalworking fluid (MWFs) especially from non-edible oil (jatropha oil). The aim of this
study was to investigate the turning performance of nanofluids from modified jatropha based-oil (MJO) with the addition
of graphene nanoparticles at various concentrations (0.01wt%, 0.025wt%, 0.05wt%). The performances of MJO based
nanofluids were compared with synthetic ester (SE) as the benchmark oil in terms of cutting temperature, chip thickness
and workpiece surface roughness. From the results, MJO + 0.025wt% graphene nanoparticles recorded the lowest cutting
temperature, and chip thickness with smoother workpiece surface roughness compared to all samples. In conclusion,
MJO + 0.025wt% exhibit superior machining performance and could be potential candidate as sustainable MWFs to
replace mineral based oil for the machining processes |
