Abstract: A method of manufacturing a plurality of parts receives cutting instructions to produce a part based on a nominal model of the part. After cutting a given part, the method measures at least one particular feature of the given part with a coordinate measuring machine and subsequently calculates an error of the given part by determining an initial deviation between the cutting instructions and the nominal model. The cutting instructions are then adjusted based on the error to obtain updated cutting instructions, where the updated cutting instructions have a reduced deviation from the initial deviation with regard to the nominal model. The method then uses the updated cutting instructions to produce another part having a reduced error deviation from the nominal model.
