Abstract (en)
[origin: DE19812133A1] The method involves measuring the change in pressure or force that occurs when the machine's working piston (4) comes into contact with the workpiece (27, to detect the start of a change of shape, e.g. the start of the riveting process. A conversion force is displayed or computed throughout the whole process by measuring pressure or differential pressure. An Independent claim is also included for a shaping machine, especially a riveting machine.
