“…In contrast, conventional EDM produces cavities with uneven and deep holes resulting from intense discharges. Wong et al 97 first concluded that the introduction of powder increased the gap by a factor of 2 compared to EDM. It was perceived that the effect of added powder in the dielectric was not very significant at lower peak current values.…”

Electrical discharge machining (EDM) is an exigent focus of interest for researchers since its inception. EDM has a wide range of applications due to its non-contact machining process based on the spark erosion method. EDM is a non-conventional machining process with high potential in the recent industrial era. Due to the few limitations of EDM, many hybrid techniques are evolved in recent years. The present review paper elucidates the in-depth mechanism of the material removal process in EDM. Hybrid EDM processes are also reviewed with special attention on powder mixed electrical discharge machining (PMEDM). A detailed comparison between the EDM and PMEDM is presented with a meticulous portrayal of the advancement and evolution of PMEDM. The emphasis is given on significant performance parameters, namely tool wear rate, material removal rate and surface roughness, besides other parameters. In addition, the study also includes different modelling, optimization, and surface analysis techniques on EDM. The paper concludes with the future scope of PMEDM in the fields of manufacturing along with its applications.

Electrical discharge machining (EDM) is an advanced machining method which removes metal by a series of recurring electrical discharges between an electrode and a conductive workpiece, submerged in a dielectric fluid. Even though EDM techniques are widely used to cut hard materials, low efficiency and high tool wear remain remarkable challenges in this process. Various studies, such as mixing different powders to dielectric fluids, are progressing to improve their efficiency. This paper reviews advances in the powder-mixed EDM process. Furthermore, studies about various powders used for the process and its comparison are carried out. This review looks at the objectives of achieving a more efficient metal removal rate, reduction in tool wear, and improved surface quality of the powder-mixed EDM process. Moreover, this paper helps researchers select suitable powders which are exhibiting better results and identifying different aspects of powder-mixed dielectric fluid of EDM.

“…Ni-Cr-Mo steel was machined to identify a relationship between material removal and tool wear ratio, showing that open voltage was the most significant factor in this relation [ 13 ]. A high MRR was achieved in the case of positive extremity, while good surface quality was achieved in negative extremity [ 17 , 18 ]. EDM with respect to economic aspects was discussed, keeping in view the input and output parameters [ 19 ].…”

The electrical discharge machining (EDM) process is one of the most efficient non-conventional precise material removal processes. It is a smart process used to intricately shape hard metals by creating spark erosion in electroconductive materials. Sparking occurs in the gap between the tool and workpiece. This erosion removes the material from the workpiece by melting and vaporizing the metal in the presence of dielectric fluid. In recent years, EDM has evolved widely on the basis of its electrical and non-electrical parameters. Recent research has sought to investigate the optimal machining parameters for EDM in order to make intricate shapes with greater accuracy and better finishes. Every method employed in the EDM process has intended to enhance the capability of machining performance by adopting better working conditions and developing techniques to machine new materials with more refinement. This new research aims to optimize EDM’s electrical parameters on the basis of multi-shaped electrodes in order to obtain a good surface finish and high dimensional accuracy and to improve the post-machining hardness in order to improve the overall quality of the machined profile. The optimization of electrical parameters, i.e., spark voltage, current, pulse-on time and depth of cut, has been achieved by conducting the experimentation on die steel D2 with a specifically designed multi-shaped copper electrode. An experimental design is generated using a statistical tool, and actual machining is performed to observe the surface roughness, variations on the surface hardness and dimensional stability. A full factorial design of experiment (DOE) approach has been followed (as there are more than two process parameters) to prepare the samples via EDM. Regression analysis and analysis of variance (ANOVA) for the interpretation and optimization of results has been carried out using Minitab as a statistical tool. The validation of experimental findings with statistical ones confirms the significance of each operating parameter on the output parameters. Hence, the most optimized relationships were found and presented in the current study.
