ABSTRACT:
A control and monitoring arrangement for "intelligent" tools is disclosed each of which is preset with a reference value for at least one assembly parameter for each assembly operation by a control unit, and each of which signals the actual value measured by means of incorporated sensors in respect of said assembly parameter to the control unit which compares that measured value to the reference value. In the control unit a plurality of reference values and/or tolerance limits in respect of difference assembly tasks is stored. Each of the tools can be used without particular operating steps, in a freely selectible sequence, for different assembly tasks at different assembly locations. The arrangement has a recognition means which, for each assembly location at which an assembly task is to be carried out, generates a recognition signal for identifying the assembly location and/or the tool, when the tool moves into the area of the assembly location, the recognition signal being transmitted to the control unit and there serving to select the at least one reference value which is desired for the respective assembly task in question and/or the associated tolerance limits.
