1. A method of detecting a fracture as it occurs in a component during a manufacturing process, the method comprising:

  • positioning an acoustic sensor in acoustic communication with the component;

    performing a manufacturing process while the acoustic sensor remains in acoustic communication with the component;

    providing a signal indicative of acoustic emissions from the component during the manufacturing process to a controller; and

    determining whether the component has fractured based on the signal.
