  • Non-contact measurement for interface gaps
    Patent number: 11920915
    Abstract: Systems and methods are provided for inspection. One embodiment is a method for measuring a hole. The method includes driving a fiber optic probe into the hole, determining a profile by scanning the hole via the fiber optic probe, and determining whether an interface gap exists at the hole based on the profile.
    Type: Grant

  • Dynamic collar swage conformance checking based on swage tool parameters
    Patent number: 11052454
    Abstract: Systems and methods are provided for inspecting fastener installation. One embodiment is a method for inspecting installation of a fastener. The method includes determining an initial distance between a nose of a swage tool and an Inner Mold Line (IML) of a part, operating the swage tool to swage a collar onto a fastener that protrudes through the IML of the part, determining a terminal distance of the nose to the IML during swaging, prior to a pintail of the fastener breaking, and arriving at a conclusion indicating a state of a fastener installation, based on the terminal distance.
