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.
