Coining is a form of precision stamping in which a workpiece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. A beneficial feature is that in some metals, the plastic flow reduces surface grain size, and work hardens the surface, while the material deeper in the part retains its toughness and ...
A coin die itself, has been the main motive for many collectors coins and medals.

[1] This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series ...

A schematic of coining with a backgauge. There are three basic types of bending on a press brake, each is defined by the relationship of the end tool position to the thickness of the material. These three are Air Bending, Bottoming and Coining. The configuration of the tools for these three types of bending are nearly identical.
