Patent ID: 8511210

Claim:
A method of cutting a laminated material made of at least first and second plates that are laid one on another and fixed together, comprising: preparing the laminated material in which the first and second plates are laid on one another in a first direction, thereby protruding a part of the second plate from an edge of the first plate in a second direction intersecting the first direction to form a protrusion; holding a layered portion of the laminated material between a pad and a clamp base that are discrete parts with respect to the laminated material in the first direction, so that the edge of the first plate is positioned between an edge of the pad and an edge of the clamp base in the second direction; and cutting the protrusion of the second plate by moving a punch along the pad in the first direction from the second plate toward the first plate, thereby using the first plate as a die to cut the protrusion of the second plate.
