System and method for verifying the dimensions of airfoils

摘要

A computer-implemented method and an apparatus for verifying geometries of airfoils (130) includes the steps of providing a part (110) having an airfoil (130) 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 (130) based on the primary datum system measurements; calculating a first deviation between the intended positional geometry and the actual positional geometry of the airfoil (130); measuring a plurality of sets of points of at least one secondary datum system; determining an actual feature geometry of the airfoil (130) 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 (130); and performing a verification of the intended positional geometry and the intended feature geometry of the airfoil (130) based upon the first deviation and the second deviation.
