Machining component using scan data of internal artifact(s)

A method of manufacture, comprising:

• computed tomography scanning a component assembly to provide scan data, wherein the component assembly includes a component, a fixture and an external artifact, the component is mounted to the fixture and comprises an internal artifact within an interior of the component, and the external artifact is arranged external to the component;
• determining external artifact data and internal artifact data based on the scan data, wherein the external artifact data is indicative of a scanned geometry of the external artifact, and the internal artifact data is indicative of a scanned geometry of the internal artifact;
• registering a first external coordinate system for the component based on the external artifact data;
• registering an internal reference point for the component based on the internal artifact data;
• updating a machining program based on data indicative of or derived from a location of the internal reference point within the first external coordinate system to provide an updated machining program;
• and
• machining a feature into the component using the updated machining program.
