Electrochemical discharge machining (ECDM) is a machining method for inorganic insulators. In this repot, the relationship between applied voltage, which is a changeable condition during ECDM, and current waveforms was experimentally compared. The effect of the initial gap between a tool electrode and workpiece was also investigated. As the applied voltage was increased, lower frequency components of the current measured during ECDM of soda lime glass in NaCl solution were decreased. The initial gap did not affect the current waveforms. The mixture of long and short pulses accelerated removal at a low applied voltage.
