Abstract
A method for manufacturing laminated parts in which spacing of individual laminas is maintained during the manufacturing process. As the laminas are stamped from strip stock material, a staking lug is formed in each lamina. The staking lug comprises an attaching lug, having a corresponding attaching cavity on an opposite surface, and a separation lug. The mating attaching lugs and cavities keep the spaced stack in a single unit configuration while the separation lug ensures adequate spacing between individual laminas for annealing and/or insulation of the individual laminas. The staking lug is preferably formed in one stamping step in a punch press machine, and eliminates the need for rotation of the laminas or alternate stamping methodologies, simplifying the laminated part manufacturing process.
