ABSTRACT
Electrochemical discharge machining a non-traditional metal removal process, which is mainly utilized to machine non-conductive as well as conductive type materials (silicon nitride, glass). This process is generally preferred owing to the key advantages, such as the possibility to manufacture the 3D complex geometrical shape of hard (diamond, carbide, tool steel) and brittle materials in micro, macro, and nano levels and produce micro holes with low residual stress, low surface roughness, and high efficiency. In addition, ECDM process has an emerging application in biomedical domain and traditionally been utilized in specialized sectors (defense, aerospace industries), manufacture nano particles, and where components with highly complicated materials of complex dimension/shape are needed. In this chapter review, the history of ECDM process, working principle, distinct process parameters, distinct types of materials used, ECDM variants, and future research possibilities are also described so that this book chapter could become the torchbearer for the coming researchers that are working in the area of ECDM.
