Abstract
Only a punched end is locally heated while a current value of a heating electrode is stabilized during heating. A forming and processing method includes punching a steel plate, and disposing a heating coil so as to face an end face of a punched end punched in the punching in a non-contact manner along the end face of the punched end and applying a current to the heating coil to generate an induced electromotive force in the steel plate, thereby heating the end face.
