Electro-hydraulic forming process with electrodes that advance within a fluid chamber toward a workpiece

A system for electro-hydraulically forming a sheet metal part in an electro-hydraulic forming (EHF) machine. The part in a first shape is placed in the EHF machine between a one-sided forming die and a chamber that is filled with a liquid. An electrode is discharged in the chamber to form the part t...

Zusammenfassung:	A system for electro-hydraulically forming a sheet metal part in an electro-hydraulic forming (EHF) machine. The part in a first shape is placed in the EHF machine between a one-sided forming die and a chamber that is filled with a liquid. An electrode is discharged in the chamber to form the part toward the forming die. The electrode is advanced within the chamber toward the part and a subsequent discharge is provided in the chamber to form the part. A gap discharge EHF machine and a wire discharge EHF machine may be used in the system.
