“…Han et al mixed graphite powder with working fluid for EDM electrolytic hybrid machining studies [19], and the experiments showed that the presence of graphite powder divided a single discharge pulse into two or three, attenuating the direct action of the EDM energy on the surface, resulting in a smooth surface. Mandal et al used a powder hybrid electrochemical discharge machining (PMECD) process to prepare micro-holes on C103 niobium-based alloy [20], again obtaining a better surface finish and lower surface roughness (Ra of 0.61 μm).…”

High quality machining of micro-holes has always been one of the challenges in the manufacturing industry, and Electrical Discharge and Electrochemical Hybrid machining (EDM-ECM), a non-traditional machining process for machining difficult-to-cut materials, is prominent in the field of micro-holes manufacturing. This paper investigates the technology and analyses the machining parameters, which are the key factors affecting its performance. The working fluid is at the heart of the proper functioning of hybrid EDM, as its presence makes it possible for EDM and ECM to co-occur. In order to enhance the machining efficiency of EDM-ECM, a triple hybrid machining method based on EDM-ECM is introduced. Finally, the scope of the technique for future research is briefly discussed.

Micro-electrochemical spark machining (µ-ECSM) is an advanced hybrid machining approach to machine materials, irrespective of their electrical conductivity. This article illustrates the state-of-the-art review of the current research on the wear mechanism of micro-tool electrodes used in the µ-ECSM process. The influence of different electrical and non-electrical machining parameters on tool wear rate, inducing dimensional inaccuracies in the fabricated components, has been addressed. The various parameters of the tool, such as the material, surface morphology and texture, shape, and size, which influence the process performance, have been discussed in detail. The requirement for technological development in the tooling area of the µ-ECSM process has been pointed out. A detailed analysis of the aforementioned areas is present in this article.
