Abstract

A method of detecting a fracture as it occurs in a component during a manufacturing process includes positioning an acoustic sensor in acoustic communication with the component. A manufacturing process is performed while the acoustic sensor remains in acoustic communication with the component. A signal indicative of acoustic emissions from the component during the manufacturing process is provided to a controller where it is determined whether the component has fractured based on the signal.
