Abstract
A hybrid metal forming system includes a die cavity defined by a first die and a second die and a press adapted to apply a static pressure over the first die to deform a workpiece against the second die. The hybrid forming system also includes a dynamic loading system coupled to and positioned between, the press and the die cavity.

A hybrid metal forming system comprising:
- a die cavity defined by a first die and a second die;
- a press adapted to apply a static pressure over the first die to deform a workpiece against the second die;
- and
- a dynamic loading system coupled to and positioned between, the press and the die cavity.

A metal forming system, comprising:
- means for moving a die to deform a workpiece under a static load;
- and
- means for indirectly dynamically loading the die while maintaining the static load.
A metal forming system, comprising:
- means for moving a die to deform a workpiece in a elastic-plastic regime;
- and
- means for indirectly loading the die against the workpiece to deform the workpiece in a hyperplastic regime.
A metal forming system, comprising:
- means for moving a die into a desired position by applying a load at a low strain rate;
