摘要： A manufacturing method is provided during which a substrate aperture is formed through a substrate of a preform component for a turbine engine using a first machining process. A coating system is applied onto the substrate to provide a coated substrate. A coating aperture is formed through the coating system using a second machining process that is different than the first machining process. The second machining process includes percussion laser drilling. At least the substrate aperture and the coating aperture collectively form a cooling aperture through the coated substrate.
