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.
