Abstract

PURPOSE:To provide a control method for electric discharge machining, using pulse voltage for the machining, in which time width of the pulse is divided into three parts and the voltage impressed at these three parts is changed so as to control the gap between electrodes depending on the condition of electric discharge, whereby stable electric discharge can be maintained during machining.
