Abstract
Precision-machined parts in aviation, automotive, and manufacturing industries have tightly controlled tolerances for the dozens of small geometries spread throughout a single part. These parts can also have stringent specifications for any defects along the surface. The sheer number of measurements needed on each part paired with the volume of parts demands the ability to take not only one measurement quickly, but dozens in a rapid process. Coupling a polarized structured light technique with robotic automation allows for accurate measurements at volume. This paper will discuss automated optical measurements of stationary parts, parts moving on a production line, and rotationally symmetric parts on a rotary stage. The paper will also look at ongoing projects combining the automated polarized structured light method with bright field techniques to accomplish automatic defect identification and inspection.
