Contact Probing
Contact or touch trigger probing can be used for pre-machining workpiece location and post-machining feature size and position verification, complete with adaptive correction if applicable. The corrections can be either part to part or used for trend correction on a statistical basis.
Turbine Blade and VANE Aerofoils are measured by the patented 6 point airfoil location and correction system. The airfoil is measured at the 6 airfoil datum points in order to determine the ‘actual’ blade position in order to machine the cooling holes in the correct location.
Aero combustor can also be measured for diameter, height and roundness prior to EDM or Laser drilling of cooling holes.
