Abstract
A method for forming a workpiece by stamping that allows spring back to be eliminated, wherein tooling () is used, at least one of the forming parts () of which includes a cavity () filled with a liquid () and provided with electrodes () capable of generating at least one shock wave in the cavity and through the wall () of the forming part, a blank material () is deformed between the two forming parts under the action of a deformation pressure and, without releasing the deformation pressure, at least one shock wave is generated in the cavity so that the shock wave passes through the blank material orthogonal to its surface. The tooling () and a press () adapted to implement the method are also described.
