Abstract
In electrical discharge machining, an electrode is displaced towards a workpiece at a rate controlled as a function of the sparking conditions. The relative position of the electrode and workpiece is measured and, beyond a preset reference relative position, advance of the electrode is slowed as a function of the displacement past the reference position, or is stopped at the reference position, while continuing sparking and allowing withdrawal of the electrode if necessitated by the sparking conditions.
