The E. D. F. has been recently developed to metal working which i s one of the high-energy-rate forming processes and this technique is industrially putting into practice.
This paper deals with some propositions on E. D. F. in oposition to the usual E. D. F. with twin rod electrode.
(1) An E. D. F. of single electrode type is characterized by that a work metal to be deformed is used as one of electrodes, resulted in simplification of a forming apparatus and a electrode composition.
(2) An E. D. F. of multi-electrode type has successfully developed for the purpose of plastic deformation of large metalic plate in the same manner as explosive forming.
(3) On the other hand, it is possible to deform a work metal by using water hammering of high-speed and high-pressure water jet which is spouted out from an orifice of the vessel, in which an impulsive high current discharge is generated.
These methods proposed by the authors have many merits it comparison with the conventional E. D. F. process.
