What is the meaning of current required in ecm for current?
Answers
Answer:
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods.[1] Its use is limited to electrically conductive materials.
ECM is often characterized as "reverse electroplating", in that it removes material instead of adding it.[2] It is similar in concept to electrical discharge machining (EDM) in that a high current is passed between an electrode and the part, through an electrolytic material removal process having a negatively charged electrode (anode), a conductive fluid (electrolyte), and a conductive workpiece (cathode); however, in ECM there is no tool wear.
