Motivation

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

3
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
Possible addition of vision system for roughness
detection

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
