Performance evaluation of biodegradable metalworking fluids for machining process
Abstract
The widely use of metalworking fluids (MWFs) petroleum-based in the industryhave a negative impact to the environment and human. Thus, various initiatives havebeen undertaken to develop bio-based MWFs especially from crude jatropha oil(CJO). However, the main drawback of CJO is that it has low thermal-oxidativestability. Therefore, the objective of this study is to develop a new formulation ofCJO-based MWFs. The newly developed modified jatropha oils (MJOs) wereformulated using transesterification process at various molar ratios of jatrophamethyl ester to trimethylolpropane (JME:TMP) denoted by MJO1 (3.1:1), MJO3(3.3:1) and MJO5 (3.5:1). Later, the MJOs were blended with hexagonal boronnitride (hBN) particles at various concentrations (0.05 to 0.5wt.%). MJOs with andwithout hBN particles were analysed based on the physicochemical properties,tribology behaviour test, orthogonal cutting and turning proses. From the results,MJO5 showed an improvement at thermal (high viscosity index) and oxidativestability (lubricant storage). MJO5c (MJO5+0.5wt.% of hBN particles) showed theoptimum physicochemical properties. In the contrary, MJO5a (MJO5+0.05wt.% ofhBN particles) exhibited excellent tribological behaviour as reduction of friction andwear, with high tapping torque efficiency. In the orthogonal cutting process, MJO5arecorded the lowest machining force and temperature, thus contributed to theformation of thinner chips, small tool-chip contact length and reduction of thespecific energy. MJO5a produced an excellent result in the machinability test byreducing the cutting force, cutting temperature and surface roughness stimulatedlonger tool life and less tool wear. In conclusion, the MJO5a has a potential impacton the lubricant market as a sustainable MWFs for the machining processes.
