This project was funded by the USAF as a collaboration of a team from industry with academia, as led by the Connecticut Center for Advanced Technology (CCAT). The team collaborated to conceptualize and fabricate 4 physical artifacts for testing. The artifacts have been carefully measured with highly accurate CMMs, with support from AF METCAL and NIST. A methodology for scanning the artifacts has also been developed and an interactive online set of instructions was created to walk the user through the process, guiding them step by step to capture the data properly, and where to upload it for archiving. 3D Systems Geomagic Control software is being utilized to support the analysis of the captured data. To do this, Automation macros and scripts were set up in Control for quickly creating spreadsheets and PDF formatted reports showing the feature measurement values and comparing them to the CMM standard values. We will present the artifact designs, how the procedure is performed, and some results as found by the team participants. It is hoped that this methodology will be considered for adoption by industry as a standard method to help confirm non-contact inspection systems capabilities across all types of systems and brands.
