Turbine blade measurementMeasurement Report

Turbine blade measurement using Focus Variation technique

The measuring object in this measurement report is a used turbine blade, measured with the optical coordinate measuring machine µCMM and a rotation unit (Advanced Real3D). 

In order to analyze the turbine blade, the following parameters are measured: 

  • geometry of a cooling hole
  • defects
  • airfoil analysis (leading & trailing edge radii, form deviation, profile twist, etc.)
  • fir tree geometry
  • profile & areal roughness
