“…Electrical discharge machining (EDM) is classified into many types which is wire EDM, micro EDM, die-sinking EDM, dry EDM, and powder-mixed EDM. The voltage within the spark gap zone growths to a point where the fluid ionizes and becomes conductive, resulting in the production and discharge of an electric pulse, which starts the process [4,5]. Many manufacturing companies are currently employing a variety of dielectric fluids, including hydrocarbon oil, mineral oil, and deionized water, among other options [6][7][8].…”

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.

“…Material is removed in electrical discharge machining (EDM) by a series of electrical discharges between an electrode and a work piece in the presence of a dielectric liquid or gas. The selection of dielectric fluid is a main consideration for EDM performance because dielectric fluid plays such an important part in every electrical discharge machining operation [15][16][17][18]. It performs a variety of activities in addition to transporting condensed metal particles from the spark gap region, all of which have a significant impact on the process's effectiveness.…”

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.

“…During the EDM process, it has been found that a significant amount of workpiece material moves from the workpiece surface to the tool surface and vice versa. In addition, continuous combustion of cutting fluid produces carbon residues that appear as visible black films on the machined surface, reducing EWR [18][19][20][21].…”

Electrical Discharge Machining (EDM) is a widely utilized commercial method for generating a variety of forms of materials that are used as the fundamental material in a wide range of industries. Vegetable oil as the dielectric fluid is one technique for assuring EDM's long-term viability because it is ecologically benign and biodegradable. This article presents experimental investigations on the influence of electrical discharge machining (EDM) input parameters on electrode wear rate (EWR) while using EDM oil and vegetable oil as dielectric fluid. Kerosene which is known as conventional oil for EDM has been used as a benchmark to compare the feasibility of the EDM process by using a different type of dielectric fluid which is RBD palm oil. Peak currents (Ip) in the 6 to 12A range and pulse durations (ton) in the 50 to 150 µs range were chosen as the major factors for this study to improve the efficiency of EDM operation. Scanning electron microscopy (SEM) was used to observe the morphology surface characteristics of the copper electrode and the migration of workpiece material elements to the tool electrode. The EWR increases with increasing peak current, although it is inversely related to pulse duration. The lowest EWR for kerosene and RBD palm oil is 0.0416mm3/min and 0.0480mm3/min, respectively, at the same IP=6A and ton=150µs. Simultaneously, the highest EWR for both kerosene and RBD palm oil was at the same IP=12A and ton=50µs, which is 0.1725mm3/min and 0.2425mm3/min, respectively.
