Abstract
A method for monitoring a mechanical joining process performed by a joining tool including a frame, a punch that is displaceable on the frame along a joining axis, a die that is mounted on the frame, and a hold-down device, which is mounted in an axially displaceable manner on the punch and biased in a joining direction; and the monitoring method comprises the steps of: starting the joining process; measuring the punch force exerted by the punch; acquiring the relative travel of the punch in relation to the hold-down device; and plotting a joining curve of punch force versus the relative travel.
