“…Crack formation/surface integrity was also studied by the researcher [132]. A fairly large percentage of research is devoted to the analysis of EDM processing of workpieces made of nickel-chromium [98,133,134] and aluminum alloys [80,120,124].…”

“…Initially, the main developments related to the numerical simulation of the process of electrical discharge machining of materials were based on the geometric modeling method (GMM), the finite element method (FEM), and the finite difference method (FDM) [10,82,115,133,[188][189][190][191]. GMM is associated with the construction of workpiece and tool surfaces within the framework of micro-geometry (shape deviation, roughness, etc.)…”

“…Over the past decades, process modeling has been developed using FEM, molecular dynamics model (MDM), and field model (FM) [18]. Moreover, FEM models have recently been widely developed [133,191], including those using the ANSYS (ANSYS Inc., Canonsburg, PA, USA) [110,196], ABAQUS (Simulia Corp., Providence, RI, USA) application software packages [81], and COMSOL Multiphysics (COMSOL Inc., Burlington, VT, USA) [197]. However, the MCE cannot investigate the formation and evolution of defect structures during a discharge at the atomic level [76].…”

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.

“…The material removal is achieved through melting and evaporation caused by high frequency electrical discharges of a conductive tool electrode (shortly, electrode) [2]. Fortunately, features such as workpiece hardness and melting temperature, which are effective in machining processes, are not important for this process [3]. Furthermore, the cutting force and its negative effects on workpiece do not occur in EDM because the electrode and the workpiece do not get into any contact during operation [4].…”

The volume of material removed from the workpiece by a pulse (Vv) in the electric discharge machining was quantitatively determined using a multi-physics simulation model in ANSYS CFX software. Electrical heating is used in the model to simulate the plasma channel formation by defining the boundary and time-controlled current density initial conditions. Time-dependent physical properties at plasma temperature were used to reflect the actual processing environment. The heat was transferred from the plasma channel to the workpiece by electrical heating from the electrode, and Vv was calculated by means of the amount of heat transfer. The calculated Vv values for AISI4140, Ti6Al4V and Inconel 718 workpieces were lower than the experimental results and the difference was observed to change between 38.3% and 46.9%.
