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 ...
Coining may refer to: Coining (metalworking), a metalworking process; Coining (mint), the production of coins; Coining (traditional medicine), dermabrasion practiced ...
Minting, coining or coinage is the process of manufacturing coins using a kind of stamping, the process used in both hammered coinage and milled coinage. [a] ...
Individuals practice this "coining", also known as cao gio (literally "scratching the wind"), amongst their own family members in many Asian countries, such as Vietnam or in Cambodia known as kaos khyal/kors kha-yal (កោសខ្យល់) literally meaning scratch the wind, and also in their respective emigrant communities abroad.

Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. [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 ...
Progressive Die is a metalworking method that can encompass punching, coining, bending and several other ways of modifying metal raw material, combined with an automatic feeding system. The feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. [1]
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.
A coining press is a manually operated machine that mints coins from planchets. After centuries it was replaced by more modern machines. After centuries it was replaced by more modern machines. Presses came in multiple shapes and with different accessories (to collect the coins, etc.)
