Coherix, Inc. and PEMAlliance Announce Successful Completion of High Definition Metrology Project

Ann Arbor, Michigan, October 27, 2014 — A project involving High Definition Metrology 3D Analysis, conducted by Coherix Inc. and PEMAlliance, brings new light to manufacturing distortion problems.

Dwight D. Carlson, Chariman and CEO of Coherix, Inc. and Chairman of PEMAlliance, announced the successful completion of the NIST ATP HDM (High Definition Metrology) 2 Micron Project. The PEMA NIST ATP HDM 2 Micron program teamed Coherix, Inc., Ford Motor Company, U.S. Department of Commerce National Institute of Standards & Technology, University of Michigan, Kettering University, Roush, MAG and Trumble, Inc. to develop the next generation of in-line process control. Carlson noted, “The last several months have focused on finalizing the project and member companies performing final audits — it’s now time to announce our results.”

HDM is a powerful tool that enables the comparison of a part in its “as build” state to its “as designed” CAD model. The “as build” state differs from the “as designed” state by the amount of what we call manufacturing induced distortion. HDM has the capability to first show a vivid 3-dimensional (3D) picture of manufacturing induced distortion and then provide measurements of the distortion. The project’s three primary areas of focus were:

    1. HDM 3D analysis of the machined surface to enable optimization of the cutter path, optimization of periodic tool changes and confirmation of first part right after start up and tool changes — enabling rapid set up and validation of machine tools.
    2. Location and dimension of features such as holes, ports and slots. Robust 3D HDM has speed, accuracy and flexibility for feature analysis, a significant tool to perform in-line feature analysis.
    3. Surface defect detection and classification of porosity, scratches, cracks, dings and dents, difficult to diagnose due to random occurrences.

Member companies have the responsibility to commercialize the products identified from the research and then deploy first for member companies’ use; second to US automobile companies and their first tier suppliers; third to other companies doing non-automotive manufacturing and ultimately global deployment. “The PEMA NIST ATP HDM 2 Micron Project was a great success and we are excited about the project’s results and what it means for the industries we serve,” said Carlson.

Coherix is a privately held, global supplier of high-speed, high-definition 3D visualization and inspection solutions designed to improve the management of manufacturing processes. Headquartered in Ann Arbor, MI the company has technical centers in Europe and the Asia Pacific region. Coherix products are being utilized around the world at companies such as Intel, Amkor, BorgWarner, Ford, Honda, Allison Transmission, Chrysler, General Motors, Micron, Infineon, John Deere, Volvo Technology Transfer and Aisin among others.
