The electrochemical machining (ECM), as a technological method, originated from the process of electrolytic polishing offered already in 1911 by well-known Russian chemist E.Shpitalsky.. It is also used to machine forging-die cavities (die sinking) and to produce small holes. Electrochemical machining (ECM) is an unconventional machining process where material removal is accomplished through controlled anodic dissolution of workpiece. Generally speaking, however, the principle characteristics of electrical discharge machining should give you a sense of whether EDM is a good fit for your application. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Though it is a new process for metal working, the basic principle had been well-known for a long time. In the process, workpiece is taken as anode and tool is taken as cathode.
