Abstract : The unexpected force of the shock wave that arises during a momentary electrical discharge in a liquid changes the form of details, shapes them and cuts complex holes and channels in the hardest materials in the course of several seconds. The electrodes are connected with a thin wire. If a sufficiently powerful current source is connected to the electrodes, then the wire, like a fuse, melts and vaporizes in an insignificant fraction of a second. But the path of the discharge has already been 'designated' and a powerful impulse of electrical current, the magnitude of which can be regulated by changing the voltage of the source or adding resistance, jumps across the electrodes. By bending the wire or replacing it with a tape or a tube, we can obtain a 'lightning' of any form: circular, spiral or zig zag. Then the electrohydraulic shock is directed to the necessary place. The wire can even be bent along the contour of the detail and then the detail will receive a stamping blow simultaneously from all sides, as occurs in a hydraulic press.
