Next, the workpiece 4 is pitch-fed in the direction of the arrow, and shaving is performed by removing the connecting portion 7 by the next punch and die. In other words, the outer contour of the component is finely cut, for example, 0.1 mm, by a punch and die set formed with almost no gap between the punch and the die. In general, the cut edge of the punched plate material is not a clean flat surface, but has a fractured surface, sag, and burr in addition to the sheared surface, and has a shape unique to the shearing process. It finishes beautifully. In addition, although the connection part 7 is fractured | ruptured by the punching of the structural member 101 in the last stage, when laminated | stacked as a deformed member, it provides in the site | part which does not make a surface state a problem in particular. The aspect of the shaving process is the same for the other constituent members 102 and 103.
