Coining
Definition
Coining is a closed-die forming operation, usually performed cold, in which all surfaces of the work are confined or restrained ,resulting in a well-defined imprint of the die on the workpiece . It is also a restriking operation used to sharpen or change an existing radius or profile.
Coining
Principle--plastic deformation
●Acold forming process ● Certain surface forms are produced with low material displacement ●The thickness of the material in the starting stock is altered.
