Relationship between applied voltage and current waveform in electrochemical discharge machining
Electrochemical discharge machining (ECDM) is a machining method for inorganic insulators.When a tool electrode is fed at a constant rate, the removal rate is often decreased due to enlarging the gap length between the tool electrode and workpiece.In this paper, the effects of the applied voltage, which is a changeable condition during ECDM, and th
