Using Pattern Recognition Technology for Validation of Model Translation & Comparison
Dr. Jim Gordon, Vice President Development
Kubotek USA, Inc.
Artificial Intelligence technology using pattern recognition has been applied to applications ranging from fingerprint matching by the FBI to image recognition engines for locating for photos on the internet. Applying similar pattern recognition algorithms to the validation of CAD geometry can provide a fast and robust method for insuring the quality of OEM master file data exchange to suppliers. This can be realized using native CAD files as well as industry standard formats like STEP and IGES. This presentation will focus on the application of validating CAD geometry using pattern matching techniques as well as contrasting this methodology to more traditional “point cloud” validation techniques. These same geometry pattern matching principles can be used for comparison applications where one version of a part or assembly can be compared to another version. Every major or subtle change in the geometry can be quickly identified using this technique. This technology has the potential of providing a solid foundation for part search and change control applications for PDM. This could enable the development of advanced PDM tools built not just on searching databases for text attributes, but on discovering the changes made to the CAD model geometry itself. As design data moves from the OEM through the supply chain in to and out of disparate supplier CAD/CAM/CAE software, subtle and sometimes undetected changes can occur altering the design geometry. These changes can be undesirable, affecting quality of the manufactured product. Validation tools can be a critical component of successful OEM master data exchange with supply chain partners. An Aerospace Supplier perspective will highlight applications for CAD Data Exchange Validation as well as Design Change Validation.
