  1. Reconfigurable System for Turbine Blade Finishing Engineering Research Center forReconfigurable Manufacturing Systems

  2. Motivation • Touch robot performs finish machining (of defects) on turbine blades • Blade Inspection Machine performs accurate dimensional measurement of turbine blades

  3. Location Calculator (Relative to the part) Measuring Machine location CAD Model Correction Action Part Robot Robot Location Data Processing Sensor Command + Finished Parts - Measuring Machine Motion Integration of Measurement and Machining • Closed loop integration of measurement and machining • Inspection machine detects and measures defects on turbine blade • Defect coordinates fed to the automatic robot for machining • Robot machines the defects • Inspection machine validates machining

  4. Integrated Hardware XYZ Positioner Turbine blade Non-contact sensor Material removal robot 2 axis rotary positioner Possible addition of vision system for roughness detection

  5. Preliminary Vision System Results gray level threshold original image with angular illumination ROI

  6. Next Steps • Detailed work breakdown structure for project • Technical specifications for hardware and software • Alignment and calibration algorithms • Measurement feasibility with laser system and vision system • Registration algorithms to map to CAD model and specify regions of defects
