12.1.5 Find
The screwdriving sample find can be used to facilitate threading the screw.
Sequence of the Screwdriving Strategy:
At the start of the screwdriving level the time monitoring and the angle measurement are
started.
Cyclic torque measurements are performed.
Switching -Off Criteria:
The screwdriving sequence is completed when
• switching off angle or the shut-off torque is reached
• the maximum screwdriving time (monitoring time) is expired
Evaluation:
OK evaluation:
The screwdriving level is considered OK (fault free), if the switching off occurs
via the angle of rotation or the torque.
Not OK evaluation:
The screwdriving level is evaluated as Not OK (faulty) if the torque is outside
the set limits or the screwdriving time has been exceeded.
Parameters:
The following parameters are used in the screwdriving sample:
• Maximum time until the switching off angle is reached (monitoring time)
• Switching off angle
• Shut-off torque
• Torque upper limit
• Speed
• End value creation: End torque/maximum torque
Selectively the result torque can be displayed as end torque (torque at end of
screwdriving) or the maximum torque (maximum occurred torque) in the end values.
