Forming aperture(s) in component using scaled CT scan data

A method of manufacture, comprising:

• computed tomography scanning an engine component and one or more artifacts to provide scan data, wherein the engine component includes a first member and a second member on the first member, the first member includes a first member aperture extending through the first member, the second member covers an end of the first member aperture, and the one or more artifacts comprise a first artifact discrete from and arranged with the engine component;
• scaling the scan data using known dimensional data for the one or more artifacts to provide scaled scan data;
• determining aperture data for the first member aperture based on the scaled scan data, wherein the aperture data is indicative of a scanned geometry of the first member aperture;
• determining a first drilling reference based on the aperture data;
• tailoring a formation operation to align a second member aperture to be formed in the second member with the first member aperture already formed in the first member based on the first drilling reference;
• and
• forming the second member aperture in the second member according to the formation operation.

A method of manufacture, comprising:

• computed tomography scanning an engine component to provide scan data, wherein the engine component includes a first member, a second member and one or more artifacts, the first member includes a first member aperture extending through the first member, the second member is disposed over the first member and covers an end of the first member aperture, and the one or more artifacts comprise a first artifact configured as a part of the engine component;
• scaling the scan data using known dimensional data for the one or more artifacts to provide scaled scan data;
