Turbomachine component machining method

An component manufacturing method includes scanning a first surface (58) of a component (50) to determine a location of pocket surfaces (78) of the first surface (58). The method machines apertures (62) in the component (50) from a second, opposite surface (56) of the component (50). The apertures (62) each have a cooling air inlet (64) within one of the pocket surfaces (78) and a cooling air outlet (66) within the second surface (56).
