Abstract
A process for manufacturing tooling, e.g., molds, from individual laminations which when stacked in the proper sequence and bonded together define a forming surface. In producing a mold, cut-outs are made by a 4 or 5-axis cutting means in the individual laminations to provide the shaping surface and optionally passageways adjacent the surface through which a heat transfer medium can be made to circulate. Also, selected ones of the laminations may be spaced in the thickness dimension of the mole to provide communication between the mold cavity and a source of pressurized air or vacuum, or the atmosphere.
