  • System and method for installation and verification of fasteners
    Patent number: 10771004
    Abstract: A method is presented for operating a power tool during installation of a deformable fastener. The method includes: receiving measures of current supplied to a motor of the power tool during operation of the power tool; determining rate of change of the current during operation of the power tool; determining occurrence of the power tool engaging the fastener based on the magnitude of the current supplied to the motor; determining occurrence of the power tool swaging the fastener based on the rate of change of the current; determining completion of the power tool swaging the fastener based on the magnitude of the current and the rate of change of the current; and verifying quality of the installation of the fastener using the determination of the occurrence of the power tool engaging the fastener and the determination of the completion of the power tool swaging the fastener.
