Turbine blade measurement using optical 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
- airfoil analysis (leading & trailing edge radii, form deviation, profile twist, etc.)
- fir tree geometry
- profile & areal roughness
