Abstract
A working electrode is positioned to form a predetermined gap between the working electrode and a surface of a work, and the electrode and the work are submerged in an electrolyte. Pulses are applied to the working electrode to machine the work. A pair of standard electrodes are set in the electrolyte, and electric energy in the form of a pulse is applied to the standard electrodes. Current flowing between the standard electrodes is detected and the current density of the current flowing between the working electrode and the work is controlled based on the detected current.
