“…Initially, this technology found its application in shaping the surfaces of conductive hard-to-machine materials with complex physical and mechanical properties [7]. Over time, the scope of this technology expanded to include materials with low electrical conductivity, such as ceramics and composites [29,33].…”

“…Electric arc welding, proposed in the 1800s by Vasily Petrov, remained the main method of shaping using electric discharges for quite a long time [5]. As stated in 1938 by L.A. Yutkin, the electrohydraulic effect [6] became the motivation for the development of the method of electro-spark processing of metals, founded by Boris and Natalia Lazarenko [7]. On 3 April 1943, the priority in the discovery of a fundamentally new method of metal April 1943, the priority in the discovery of a fundamentally new method of me cessing was confirmed by these USSR authors.…”

Electrical discharge machining (EDM) is a highly precise technology that not only facilitates the machining of components into desired shapes but also enables the alteration of the physical and chemical properties of workpieces. The complexity of the process is due to a number of regulating factors such as the material of the workpiece and tools, dielectric medium, and other process parameters. Based on the material type, electrode shape, and process configuration, various shapes and degrees of accuracy can be generated. The study of erosion is based on research into processing techniques, which are the primary tools for using EDM. Empirical knowledge with subsequent optimization of technological parameters is one of the ways to obtain the required surface quality of the workpiece with defect minimization, as well as mathematical and numerical modeling of the EDM process. This article critically examines all key aspects of EDM, reflecting both the early foundations of electrical erosion and the current state of the industry, noting the current trends towards the transition of EDM to the 5.0 industry zone in terms of safety and minimizing the impact of the process on the environment.

“…However, soviet scientists exploited the destructive properties of electrical discharges for constructive use and developed a controlled method of metal machining to machine metals by vaporizing material from the surface of the metal. Furthermore, in the 1950s, Lazarenko EDM systems that used a resistance-capacitance type of power supply were widely used in EDM machines, and later acted as models to enhance EDM [3].…”

In this study, the effect of nickel powder mixed dielectric fluid on Electrical Discharge Machining (EDM) performance of mild steel has been carried out. Peak current, tool/electrode diameter and concentration of powder are the process parameters. The process performance is measured in terms of material removal rate (MRR), tool wear rate (TWR), and surface roughness (SR). The experiment has been designed using a Full Factorial in Design of Experiment (DOE) software. The research outcome is to identify the important process parameters that maximize MRR and minimize TWR and SR. The experiment has been carried out using 2 levels of current (3.5 A and 6.5 A), tool diameters (14 mm and 20 mm) and Nickel powder concentrations (0 g/l and 6 g/l). The weight of the mild steel work piece and copper electrode are measured before and after each run. Based on the results, current is the most significant parameter affecting MRR, TWR, and SR. It was also found that with added nickel powder in the dielectric fluid, the tool life is longer and surface roughness of the work piece is improved. Furthermore, it was shown that both MRR and TWR increased with the increase in tool diameter. However, SR was improved as tool diameter increased but its effect was not very significant. ABSTRAK: Dalam kajian ini, mutu keberhasilan campuran serbuk nikel cecair dielektrik pada Sisa Mesin Elektrik (EDM) ke atas besi ringan telah dijalankan. Arus tertinggi, alat/diameter elektrod dan ketumpatan serbuk adalah parameter kawalan. Pencapaian proses diukur dari segi kadar penyingkiran bahan (MRR), kadar penggunaan alat (TWR) dan kekasaran permukaan (SR). Eksperimen ini direka bentuk dengan menggunakan perisian Faktorial Penuh dalam Rekaan Eksperimen (DOE). Hasil kajian ini adalah untuk mengidentifikasi kepentingan parameter kawalan yang mengoptimumkan MRR, meminimumkan TWR dan SR. Eksperimen ini dijalankan pada 2 peringkat arus elektrik (3.5 A dan 6.5 A), diameter alat (14 mm dan 20 mm) dan ketumpatan serbuk nikel (0 g/l and 6 g/l). Berat bahan uji seperti besi ringan dan elektrod tembaga diukur pada sebelum dan selepas setiap ujian. Berdasarkan keputusan, arus elektrik adalah faktor paling ketara yang mempengaruhi MRR, TWR, dan kekasaran permukaan. Turut didapati pada setiap pertambahan serbuk Nikel ke dalam cecair dielektrik, jangka hayat alat turut bertambah dan kekasaran permukaan pada bahan uji turut bertambah baik. Selain itu, kedua-dua MRR dan TWR bertambah dengan setiap pertambahan diameter alat. Sebaliknya, kekasaran permukaan bertambah baik dengan pertambahan diameter alat tetapi kesannya tidak ketara.

This paper aims to optimize the machinedsurface as well as to study the effect of current strength andwire speed on wire cut machining on AISI 1045 steel againstthe timing of roughness of straight gear surface. The surfaceresults analyzed are the surface roughness values obtained byconducting surface roughness testing. Variations of currentused are 3 amperes, 5 amperes, and 7 amperes, while the wirespeed used is 8mm / min, 10 mm, min, and 12 mm / min. In theprocess of wire cut machining is used a brass cutting materialwith 0.25 mm wire diameter. The results showed that thegreater the current and wire speed used then the surfaceroughness value will be lower, otherwise the smaller currentand wire speed used then the surface roughness value will behigher. The results of data analysis using ANOVA analysis,correlation, and regression method obtained optimal conditionto get low surface roughness value and fast cut time that is at 7amperes current with wire speed 8 mm / min.
