Description

System and method for determining pore characteristics of a pore Technical Field The present disclosure relates generally to manufacturing and inspection, and more particularly, to a system and method for determining hole characteristics of holes formed through manufactured parts. Background Parts manufactured from stacks of material layers, such as composite, metallic, or polymeric materials, are typically secured together using fasteners that extend through aligned holes in the material layers. However, such stacks of material may exhibit misaligned apertures, gaps in interface regions, or other inconsistencies. Although this inconsistency may be small, even a small inconsistency may be out of tolerance, depending on the intended field of use of the resulting part. For example, aerospace parts may have particularly tight tolerances. Thus, it may be desirable to identify and resolve such inconsistencies. Unfortunately, identifying such inconsistencies and determining the pore characteristics of the pores remains complex and time consuming. Accordingly, those skilled in the art continue to conduct research and development efforts in the field of inspection and analysis during the manufacture and assembly of parts. Disclosure of Invention Examples of a system for determining a hole characteristic of a hole, a measurement tool for measuring a hole, and a method for determining a hole characteristic of a hole are disclosed. The following is a non-exhaustive list of examples according to the subject matter of the present disclosure, which may or may not be claimed. In an example, the disclosed system includes a measurement tool and a controller. The measurement tool is configured to measure the hole and generate data representative of the hole. The controller is in communication with the measurement tool and is configured to determine at least one of the hole characteristics based on data from the measurement tool. In another example, the disclosed measurement tool includes a housing, a collet, an optical probe, a linear drive, and a rotary drive. The collet is coupled to the housing and configured to engage a portion of the bore. The optical probe is configured to extend through the collet and into the bore, scan the wall of the bore, and generate data representative of the wall of the bore. The linear drive positions the optical probe along the scan axis. The rotary drive positions the optical probe about the scan axis. In an example, the disclosed method includes the steps of (1) extending an optical probe into a bore along a scan axis, (2) rotating the optical probe within the bore about the scan axis, (3) scanning a wall of the bore, (4) generating data representative of the wall of the bore, and (5) determining at least one of a plurality of bore characteristics based on the data.
