Abstract

The electro-hydraulic plastic deforming method belongs to non-conventional plastic deforming techniques class. The shape of the discharging chamber and of the energy concentrators influences workpiece machining, along with the other parameters of the equipment (electrical pulses, electrodes, space between electrodes, pressure wave transmission medium, way to propagate the pressure wave). The paper proposes a comparative analysis of the geometric parameters of the discharging chambers and of their effects on the technological processing.
