Abstract
A method of controlling a rotary impact tool includes activating a motor to provide torque to a drive assembly, providing rotational impacts to a torque stick coupled to an anvil of the drive assembly in response to a reaction torque on the drive assembly exceeding a threshold value, and sensing a position of the anvil with a position sensor. The position sensor transmits a first signal indicative of the anvil rotating in a first direction and a second signal indicative of the anvil rotating in a second direction, where the second direction is a rebound angle of the anvil. The method further includes calculating a torque transferred from the torque stick to a workpiece by multiplying the rebound angle by a torsional stiffness value of the torque stick and deactivating the motor in response to the torque exerted on the workpiece being substantially equal to a torque limit.
