Continuous implementation of lubricants from renewable sources such as animal fats, vegetable oils andbiolubricants as metalworking ﬂuids in machining applications was contributed by the increase awarenessfrom human health deﬁciency and bad environmental impacts as well as on sustainable development for
future manufacturing activities. Renewable lubricants from vegetable oils are very attractive as alternative
lubricant source which pose relevant properties such as highly biodegradable, non-toxic, have good lubricating
properties, are made from renewable sources and bear low production costs. Vegetable-based metalworking
ﬂuids from palm oil and jatropha oil are desirable as the alternative to mineral oil that possessed negative eﬀect
to human and environment. The assessment of its performance was conducted tribological and machinability
aspects. Both palm and jatropha oils were chemically modiﬁed through various processes and added with anadditive, such as ionic liquid and hexagonal boron nitride. The tribological properties of the palm and jatrophaoils were further improved in terms of its friction and wear performances by adding the additives. The
machining performances of these newly invented vegetable-based MWFs were evaluated in terms of cutting
forces, cutting temperature, surface roughness and tool life during turning of AISI 1045 medium carbon steel
using uncoated cermet inserts under MQL technique. The thin lubrication ﬁlm formed by the vegetable-basedoils was able to withstand the friction at the tool-workpiece interface, resulted in low cutting force, low cutting
temperature, lower surface roughness value and prolonged tool life. This phenomenon was attributed to theformation of long and branched carbon chains in palm and jatropha oils molecule which increased theabsorption ﬁlm ability. From the results of the tribological and machining performances evaluations, the newly
developed vegetable-based MWFs were signiﬁcantly surpassed currently used synthetic ester thus provides
new opportunities for minimum quantity lubrication-based oil.
