Abstract

A method for inspecting components includes providing a plurality of different three-dimensional component CAD models with each three-dimensional component CAD model of the plurality of different three-dimensional component CAD models sharing at least one common geometric feature. The method further includes generating an inspection sequence for the at least one common geometric feature, collecting feature manufacturing data for the at least one common geometric feature during manufacturing of a plurality of different components corresponding to the respective plurality of different three-dimensional component CAD models, analyzing the feature manufacturing data associated with the at least one common geometric feature, modifying the inspection sequence for the at least one common geometric feature based on the analyzed feature manufacturing data, and inspecting components based on the modified inspection sequence.

6 . The method of claim 5 , wherein the step of analyzing the feature manufacturing data includes determining one or both of a process capability (Cpk) and a process performance (Ppk) for the at least one common geometric feature.

7 . The method of claim 6 , wherein the step of modifying the inspection sequence includes reducing the inspection frequency for the at least one common geometric feature when the one or both of the Cpk and the Ppk is greater than a predetermined threshold value.

8 . The method of claim 6 , wherein the step of modifying the inspection sequence includes reducing the number of inspection measurements for the at least one common geometric feature when the one or both of the Cpk and the Ppk is greater than a predetermined threshold value.

9 . The method of claim 1 , further comprising indexing the at least one common geometric feature by assigning the at least one common geometric feature a unique identification code.

11 . The method of claim 10 , wherein the feature manufacturing data includes an inspection history of the at least one common geometric feature.

12 . A system for inspecting components, the system comprising:
a processor; a database in signal communication with the processor; and memory in signal communication with the processor, the memory containing instructions recorded therein which, when executed by the processor, cause the processor to:
collect component manufacturing data for at least one common geometric feature during manufacturing of a component, the component corresponding to a three-dimensional component CAD model which is one of a plurality of different three-dimensional component CAD models in the database sharing the at least one common geometric feature;
analyze the component manufacturing data;
