A system for forming sheet metal ( ) is disclosed. The system comprises a support plate ( ) that is coupled to a base ( ) and has at least one side plate ( ) adjacent thereto. A clamping mechanism ( ) fixes the side plate ( ) to the support plate ( ) so sheet metal ( ) can be formed.

System and method for forming sheet metal using a reconfigurable tool

Tooling apparatus for three-dimensionally forming a honeycomb core article includes a die having an array of elongated mutually parallel translating pins, each having a pin tube terminating at a tip end and arranged in a matrix for longitudinal movement between retracted and extended positions. The tip ends of the array of translating pins are engageable with an end surface of the honeycomb core article when in the extended position. Each tip end includes a pin tip assembly including an elongated pin tip member having an outwardly projecting bearing surface of shape conformable material on which is mounted a protective thrust pad, an opposed bottom surface, and an outer peripheral surface extending between the bearing surface and the bottom surface. A cup-shaped retainer having a base and an upstanding wall with an outer peripheral surface is provided for mounting engagement with the tip end of each pin tube and has an internal recess with a base surface and an internal peripheral surface. The pin tip member is mounted on the retainer, the outer peripheral surface of the pin tip member engaged with the internal peripheral surface of the retainer and the bottom surface of the pin tip member engaged with the base surface.
