Generation of feedback for a part production process based on vibrational testing of parts produced by the part production process. A response characteristic may be identified from vibrational data regarding the parts that is correlated to a process variable of the part production process. The response characteristic may relate to a state of the process variable such that identification of the response characteristic may allow for generation of feedback regarding adjustment of a process control. Such response characteristic may relate to a vibrational metric regarding vibrational data and may comprise identifying a trend in data between a plurality of parts. Also presented are approaches to evaluation of parts, including batch evaluation of parts in which collective vibrational data regarding a plurality of parts belonging to a batch are analyzed. The process control aspects may be performed independently or in combination with part evaluation.

Use of resonance inspection for process control

Resonance inspection of parts in which a resonance standard to which a frequency response of the part is compared is at least in part based on a property derived from testing of a witness coupon that is manufactured concurrently with the part. This approach may allow properties of a material and/or manufacturing technique used to produce the part and witness coupon to inform the resonance standard to improve testing. Approaches are described related to both empirically derived resonance standards as well as model-based resonance standards.

Resonance inspection of manufactured parts with witness coupon testing

Various embodiments relating to resonance inspections and in-service parts are disclosed. One protocol () includes conducting a resonance inspection of an in-service part (). The frequency response of the in-service part may be compared with a resonance standard () for purposes of determining whether or not the in-service part is changing abnormally (). An in-service part that is identified as changing abnormally may be characterized as being 'rejected' (). An in-service part that is no identified as changing abnormally may be characterized as being 'accepted' ().

Utilizing resonance inspection of in-service parts

A part () may be subjected to both a resonance inspection and a surface vibration inspection. Various protocols () are disclosed as to how the results of one or more of these inspections may be used to evaluate the part ().
