Comparative studies of ecm, edm and ecam

The characteristics of electrochemical and electrodischarge machining are compared with electrochemical arc machining, a process which relies on electrical discharge in electrolytes to effect metal removal. Since little is known about the nature of this process, investigations of sparks in dielectrics and electrolytes are reviewed. Some relevant applications of edm and ecm are then discussed, and comparisons drawn with the new process
