In order to repair the airfoil section of the blade only automatic operation perception the system and manner in order to machine automatically

摘要

A method for repairing an airfoil (34) comprises creating a nominal numerically-controlled tool path based on a nominal shape of the airfoil (34), measuring the airfoil (34) using a displacement sensor (66), capturing differences in the airfoil (34) shape as compared to the nominal shape, creating a three-dimensional map by synchronizing x, y and z coordinates and readings from the sensor (66), modifying the tool path based on the three-dimensional map, and machining the airfoil (34). A system for measuring and machining an airfoil (34) comprises a computer (60) operable for data acquisition and numerically-controlled tool path generation, a numerically-controlled machine (62), a cutting tool holder (64) comprising a plurality of cutting tools (68), and a displacement-sensing probe (66).
