1. A manufacturing method, comprising:
providing a preform component for a turbine engine, the preform component including a substrate and a locating feature at an exterior surface of the substrate;
applying an outer coating over the substrate, wherein the outer coating covers the locating feature;
scanning at least a portion of the preform component and the outer coating with an imaging system to provide scan data indicative of a location of the locating feature; and
forming a cooling aperture in the substrate and the outer coating based on the scan data.
 
16. A manufacturing method, comprising:
providing a preform component for a turbine engine, the preform component comprising a substrate;
applying an outer coating over the substrate;
forming a first section of a cooling aperture in at least the outer coating using a first machining process; and
forming a second section of the cooling aperture in the substrate based on a location of a locating feature at an end of the first section.
 
20. A manufacturing method, comprising:
providing a preform component for a turbine engine, the preform component comprising a substrate;
applying an outer coating over the substrate;
forming a diffuser section of a cooling aperture in the outer coating and the substrate using a first machining process;
forming an indentation in the substrate at an end of the diffuser section; and
forming a meter section of the cooling aperture in the substrate using a second machining process, wherein the meter section is formed based on a location of the indentation.
