PROCESS FOR CONTROLLING ELECTRICAL DISCHARGE SHAPING

A process for electrical discharge shaping a workpiece by impressing a pulse voltage across a working gap between the workpiece and an electrode, wherein a waveform of the pulse is controlled by effectively discharging the pulse. The working gap is controlled, so as to contribute to stable processin...

description A process for electrical discharge shaping a workpiece by impressing a pulse voltage across a working gap between the workpiece and an electrode, wherein a waveform of the pulse is controlled by effectively discharging the pulse. The working gap is controlled, so as to contribute to stable processing, depending upon the controlled pulse waveform. A pulse time width is divided into three intervals. When the discharge is formed during the first time interval the electrode movement is controlled to increase the working gap. When the discharge is formed during the second time interval, the electrode movement is controlled to maintain the working gap. When the discharge is formed during the third time interval or no discharge is generated, the electrode movement is controlled to decrease the working gap.
