Abstract

See full text

A trim tool for trimming a part having a complex shape. The trim tool defines a plurality of electro-hydraulic cavities that are separated by walls in a lower die of the trim tool. Electrodes are discharged in the electro-hydraulic cavities to drive the panel into engagement with a trim steel edge. The discharge of the electrode severs the panel above the cavity and also across a portion of a wall separating adjacent cavities. Discharging an electrode in an adjacent cavity completes the trim operation above the wall.
