Jürgen Hierold: If the part's geometry does not match the reference value, perhaps because the metal part has flexed, the screwdriver process and the torque parameters selected automatically adjust to the changed shape of the metal sheet. Only once this has occurred is an enable signal emitted so that the screwdriving process can start. Finally, the last step is to check the condition of the joining process. The parameters are individually analysed, compared against the reference values and, if they are within the tolerance range, confirmed with an “OK” message. This method ensures continuous quality control.
