MANUFACTURING METHOD OF THICKNESS-VARIED METAL PLATE, MANUFACTURING METHOD OF PRESSED PART, AND PROCESSING MACHINE

摘要

In a manufacturing method of a thickness-varied metal plate, first, a cut plate is manufactured by cutting a metal plate having a constant plate thickness into a predetermined shape. Next, the thickness-varied metal plate is manufactured by rolling the cut plate using a processing machine including a pair of work rolls. Here, a radius of one of the pair of work rolls is varied in a circumferential direction and an axial direction. Accordingly, the thickness-varied metal plate manufactured by rolling the cut plate using the processing machine has a plate thickness varied in two different directions orthogonal to a plate thickness direction.
