Notes:
A miniaturized Electrical Discharge Machine (EDM) device based on ultrasonic motor hasbeen developed to machine micro-holes in narrow space. In this mechanism, the electrode is drivenwithout need of electrode holder, so that the mass and inertia of slider are greatly smaller, and feedingfrequency of electrode can be raised compared to the conventional miniaturized EDM devices. This isa significant improvement that the electrode’s driving means varies from plane driving to line driving.Because of its advantage of compact size, the miniaturized EDM device can be fixed on robot.Differential Reciprocating Driving Method (DRDM) for EDM electrode is proposed. Feedingresolution of electrode reaches 0.5μm in stepping style, while resolution reaches 40nm in differentialreciprocating style, and all above characteristics create preconditions for micro EDM machining. Theholes with figures of Φ90μm inclined circle and inclined Y have been machined
