Electrical Discharge Machining (EDM) is a machining process in terms of thermoelectric that removes metal by discharging a discrete sparks series of the metal and workpiece. The cutting tool in EDM has used an electric spark to cut the workpiece of sample and produce the finished part to the demanded shape. Vegetable oil as the dielectric fluid is one way to ensure EDM's long-term viability because it is environmentally friendly and biodegradable. The main objective of this preliminary study is to compare the uses of modified bio-degradable and conventional dielectric fluid performance for a titanium alloy (Ti-6Al-4V) with a copper (Cu) electrode using a sustainable EDM process in terms of electrode wear rate (EWR). To achieve a concentration of viscosity rate as kerosene fluids, RBD palm oil has been transesterified. The effect of EWR of kerosene and modified RBD palm oil as dielectric fluids was investigated in this paper for response variables of pulse duration (ton) of 50, 100, and 150μs, and peak current (Ip) of 6, 9, and 12A. The morphology of the copper electrode, as well as the migration of workpiece material elements to the tool electrode, were studied by using scanning electron microscopy (SEM). The lowest EWR was recorded at Ip=6A with ton=150μs, which is 0.0416mm3/min and 0.0432mm3/min, and the highest EWR was recorded at Ip=12A with ton=50μs, which is 0.1725mm3/min and 0.2324mm3/min, for modified RBD palm oil compared to kerosene, respectively. The EWR rises as thepeak current rises, but it decreases as the pulse duration increases. The uses of modified RBD palm oil shows slightly different results compared to kerosene.

“…Austenitic grain boundaries are observed by using an optical microscope and the grain size is counted by intercept method according to ASTM E112 and application of image-J. The hardness of both the tested steel 253 MA and 316L were measured by using Vickers Hardness Tester using load of 0.3 N. The creep's plate specimen was prepared according to ASTM E8 by wirecut electrical discharge machining (wire-cut EDM) which it can be machining complex geometries of subsize specimen 20) . The creep rupture test was performed at the temperature constant of 700 ℃ under the stress of 150 MPa by using ZwickRoell Creep Tester.…”

The high chrome heat-resistant steel is commonly used as a part of an ultrasupercritical steam boiler and creep failures are usually observed after the part has been exposed to constant high boiler temperature operation. The heat-resistant steel 253 MA which contains high chrome of about 22 wt.% is usually found to be used for steam boiler pipe, so as it is interesting to investigate and evaluate the behavior of creep rupture of this steel and the relationship with microstructure and mechanical properties. The 253 MA heat-resistant steel material was cut and deformed using cold rolling to about 35% thickness reduction and heated at temperatures constant of 900, 1000, 1100 and 1200 ℃ for 0, 240, 420, 840, and 3600 seconds at each temperature under heating rate of 10 ℃/minutes and then quenched. Another high chrome heat-resistant steel 316L is also used as an investigated steel for validation of the austenite grain growth. The creep rupture test was carried out at a temperature of 700 ℃ and a stress of 150 MPa. The result of this study is evaluated as a modified model which describes the relationship of the Larson-Miller parameters between hardness and austenitic grain size, and it is found that the modified model seems to be in close agreement with another high chrome steel which has been reported in previous work.

“…It also has the advantage of being reusable and not causing harm to the environment or human health when in use [17][18][19][20][21]. Because of its biodegradability and lack of pollutants, RBD palm oil has been found to improve the machining process and is clearly the greatest option for kerosene [18,19,[22][23][24]. To increase the sustainability of the electric discharge machining (EDM) process, Valaki et al, [25] carried out an experiment to examine the technical viability of a recently developed Jatropha curcas oil-based bio dielectric (Jatropha BD) fluid.…”

The type of dielectric fluid is the most significant component that might affect the machining performance of EDM such as material removal, tool wear, and electrode surface roughness. However, the most serious of these issues is the inability to comply with health and environmental rules when the conventional dielectric was harmful to the surrounding ecosystem. One approach to ensure the long-term sustainability of EDM is to use vegetable oil as the dielectric fluid as it is environmentally friendly and biodegradable. To satisfy industrial objectives, the machining industry must ensure that the maximum material removal rate (MRR) can be achieved. This paper investigated the effect of kerosene and refined, bleached, and deodorised (RBD) palm oil as dielectric fluids with different peak currents (6, 9, and 12A) and pulse duration (50, 100 and 150µs) settings on MRR of Titanium alloy. Kerosene was used as a benchmark to compare the performance of the EDM process. The implementation of RBD palm oil recorded the lowest MRR at the lowest peak current of 6A with the lowest pulse duration of 50µs, which is 1.1260mm3/min. In contrast, the highest MRR with a value of 12.1323mm3/min was recorded at the highest peak current of 12A with a pulse duration of 150µs. Overall, RBD palm oil shows an excellent MRR performance for substituting hydrocarbon or mineral oil as a dielectric fluid in EDM applications, improving cost, time, and production efficiency.
