Abstract
A method for forming a cooling hole diffuser in a component includes forming a cooling passage precursor through the component, the cooling passage precursor having a meter center; applying a coating to the component including portions of the cooling passage precursor to create an at least partially coated cooling passage having a meter remnant center that is offset relative to the meter center; and removing material from the at least partially coated cooling passage to form a finished cooling passage, wherein the step of removing material is guided optically based upon the meter remnant center and a correction from the meter remnant center to the meter center.
