Abstract

During a manufacture method, a component is scanned using a CT machine. The component includes a first member and a second member. The first member includes a first member aperture extending through the first member to the second member. Aperture data is determined for the first member aperture based on scan data. A centerline vector is determined for the first member aperture. The determining of the centerline vector includes fitting a geometric primitive to the aperture data to describe at least a portion of the scanned outer perimeter geometry of the first member aperture. The centerline vector for the first member aperture is determined based on a centerline vector of the geometric primitive and/or a center point of the geometric primitive. A point of intersection between the centerline vector and a reference plane is determined. A second member aperture is formed in the second member according to a formation operation.

Dependent claims

A method of manufacture, comprising:

scanning a component using a computed tomography machine to provide scan data, wherein the component includes a first member and a second member covering the first member, and the first member includes a first member aperture extending through the first member to the second member;
determining aperture data for the first member aperture based on the scan data, wherein the aperture data is indicative of a scanned outer perimeter geometry of the first member aperture;
determining a centerline vector for the first member aperture, wherein the determining of the centerline vector comprises fitting a geometric primitive to the aperture data to describe at least a portion of the scanned outer perimeter geometry of the first member aperture, and the centerline vector for the first member aperture is determined based on at least one of a centerline vector of the geometric primitive or a center point of the geometric primitive;
determining a point of intersection between the centerline vector and a reference plane;
and
forming a second member aperture in the second member according to a formation operation that aligns the second member aperture being formed with the first member aperture in the first member based on the point of intersection and the centerline vector.
