Burrs on turbine blades, discs or blisks are potential failure points, but measuring the complex geometries at speed in a production environment is challenging.  But as MTU Aero Engines in Germany have discovered, the answer is Alicona.  The Alicona Cobot has shown itself to be up to the challenge of automated measurement of difficult to access geometries with demanding tolerances and surface finishes from matt to highly reflective.

Burr formation and unwanted sharp edges are a consequence of turning, milling and grinding and are potential weak points where crack initiation and ultimately breakage can occur.  This is why stringent requirements exist for measurement of edge profiles.

The Cobot delivers the assurances needed, providing automated measurement of the smallest form deviations to single digit µm resolution). Import of the component’s CAD file and programmed test routines automates the pass/fail decision.
