Torque + angle controlled untightening
In addition to monitoring the untightening of the fastener, the system monitors the number of degrees reached while
maintaining a residual torque in the fastener.
The control phase starts IF torque > breakaway torque
The recorded values are the following: final torque and final angle
Spindle stop
IF torque ≤ target torque OR torque > safety torque
OR angle > max. angle
Accept report
IF torque < safety torque
AND min. torque ≤ final torque ≤ max. torque
AND min. angle ≤ final angle ≤ max. angle
Angle + torque controlled untightening
The recorded values are the following: final torque and final angle
Spindle stop IF angle ≥ target angle OR torque > safety torque
Accept report IF torque < safety torque
AND min. torque ≤ final torque ≤ max. torque
AND min. angle ≤ final angle ≤ max. angle
