Abstract
Stamping dies and method for stamping parts using multiple stamping stations with different bottom markers in successive dies that mark the part being produced at selected stations with different markings related to one another, which cumulatively provide an observable completed set of marks on a part such as one finally stamped to readily show whether or not the stamping has been properly executed and to identify any stamping station or stations that is not stamping to specification.
