Abstract: An integrated automated 3D Optical Scanning and Computer Aided Inspection System for dimensional inspection of precision manufactured parts. The system is based within a portable cabinet having lockable caster wheels for portability and retractably support feet for enhanced stability. The cabinet further includes a part placement area having an optical metrology scanner positioned over a multi-axis robotic arm positioned in the part placement area. The robotic arm is constructed and arranged to grip and manipulate parts within a field of view of the optical metrology scanner. The robotic arm provides multi-axis to rotate and tilt a base to allow substantially every surface of the part to be scanned. Dimensional comparison and analysis software application provide geometric conformance/deviation plus extraction of the dimensions indicated in the part computer aided design (CAD) model.

Abstract: The invention is directed to a method and apparatus for pretreatment an object to be white light scanned to enable accurate and consistent scanning. In those instances where the object part has a reflective or refractive surface or is made from a material having translucent or transparent properties the object must be pretreated to ensure accurate data collection during the scanning process. The object is coated with a composition forming a thin and uniform film of non destructive material coating to enhance the surface contrast characteristics for the mono-chromatic fringe pattern employed in the white light scanning process.
