Abstract: A method of predicting machined part variations for design optimization is provided. The method includes receiving computerized specifications for a part and tooling specifications for tooling used for building the part, producing the part using virtual machining based on the computerized and the tooling specifications and producing variations of the part using the virtual machining based on the computerized and the tooling specifications and based on variations of at least some of the tooling specifications.

Abstract: A method of determining wear of a seal element includes rotating a seal plate relative to the seal element and such that the seal plate and the seal element form a rotational sealing interface. The seal element includes an insert embedded in the seal element. A portion of the seal element is worn with a sealing face of the seal plate. The insert is contacted with the sealing face of the seal plate. A portion of the insert is worn to create a wear particle of the insert. The presence of the wear particle in a lubrication oil is sensed with an oil monitoring system.
