ABSTRACT:
A computer-implemented method for verifying geometries of airfoils includes the steps of providing a part having an airfoil having an intended positional geometry and an intended feature geometry; measuring a first set of points of a primary datum system; determining an actual positional geometry of the airfoil based on the primary datum system measurements; calculating a first deviation between the intended positional geometry and the actual positional geometry of the airfoil; measuring a plurality of sets of points of at least one secondary datum system; determining an actual feature geometry of the airfoil based on the at least one secondary datum system measurement; calculating a second deviation between the intended feature geometry and the actual feature geometry of the airfoil; and performing a verification of the intended positional geometry and the intended feature geometry of the airfoil based upon the first deviation and the second deviation.
