Method for monitoring a mechanical joining process, in particular a punch-riveting or clinching process, the joining process being performed by means of a joining tool (12), which has a frame (30), a punch (34) that is displaceable on the frame (30) along a joining axis (38), a die (32) that is mounted on the frame (30), and a hold-down device (40), which is mounted in an axially displaceable manner on the punch (34) and biased in a joining direction, the method comprising the steps, during the joining process: acquiring the punch force (F) exerted by the punch (34), acquiring the relative travel (S R ) of the punch (34) in relation to the hold-down device (40); and plotting a joining curve (60) of punch force (F) over the relative travel (S R ). |
