ABSTRACT:
The machining efficiency is markedly increased in EDM by having a plurality of vibration horn assemblies in engagement with a tool assembly at preselected different positions on the surface thereof. The electromechanical transducers in the horn assemblies are individually energized to provide a burst of mechanical vibrations from the vibration output face of the horn member in each vibrator assembly in contact with the tool assembly and to allow the burst to be transmitted to the machining surface of the machining electrode to vibrationally activate a selected area thereof. The plurality of the vibrational bursts produced at the different locations on the tool assembly are combined, by being applied sequentially or at a time, to allow the machining surface of the electrode to be vibrationally activated uniformly over the entire area thereof. The arrangement is advantageously applicable to a variety of electrodes which may be large and to machining a deep and narrow, and/or intricate cavity in the workpiece.
