Control means for the relative displacement of the electrodes of an EDM apparatus |
摘要 |
In an EDM apparatus in which the relative displacement between an electrode tool and an electrode workpiece is effected by a servo motor, a control system for the servo motor to effectuate the relative displacement of the electrodes at a speed depending from the machining conditions at the gap between the electrodes and from the difference between a reference position signal and a signal representing the actual relative position of the electrodes, such as to limit the relative displacement of the electrodes until a predetermined final relative position has been reached.
