An apparatus and method for manufacturing laminated parts from a plurality of laminas, in which the laminas for forming the laminated parts are blanked from strip stock material. The laminas and are then cut and stacked to form the laminated part. The apparatus includes a measuring device placed with the die element of the press, for accurately measuring the thickness of successive sections of the strip stock. A controller, such as a computer or a programmable logic controller, receives the thickness value of the strip stock sections from the measuring device.
