Torque angle curve and torque gradient
The torque gradient shows how the torque is applied in the last phase of the Tightening screw
command. This could be used as an indicator to detect if a Tightening command is performed
correctly.
For instance, the torque gradient could be different if:
•
The hole thread is not long enough
•
The hole thread is different from the screw thread
•
The hole thread is not clean (for instance by deburrs from CNC machining)
•
The friction between the screw thread and the hole thread is too low or too high
•
The friction between the screw head and the tighten part is too low or too high
A torque gradient variable is made available to be checked in the robot program.
The graph below shows a normal Torque/Angle curve. In this case has been made with a M4
screw and 2.4 Nm as target torque.
