Abstract
A clinching station for securing a first workpiece to a second workpiece includes control logic receiving a punch position sensor output and processing the punch position sensor output and an established position signature to generate a clinching operation status signal. The clinching station includes a punch and die assembly including a punch and a die mounted opposite each other for movement relative to each other along a working axis. A position sensor is configured to monitor the position of the punch relative to the die, and has an output indicative of the position of the punch relative to the die. The established position signature corresponds to an acceptable clinching operation, and allows the control logic to generate the clinching operation status signal.
