Abstract
An improved method for manufacturing a vacuum port manifold having a plurality of ports each having a planar sealing surface derived from an intermediate unitary structure having a compound curved surface at least in part. The planar sealing surfaces are formed by machining selected planes across the corresponding compound curved surface.
