Chapter 6 Fastening Operation
PAGE 6-29
●Rate Check
Three torque rate areas capable of judging the rise of torque vs. angle (slope) can be used to monitor the
fastening operation.
A rate start torque (angle) and a rate end torque (angle) set the boundaries of each area and the torque
slope (slope of the torque vs. angle) between the two points is calculated to make the judgment once the
end point is reached. (Example: 25N•m÷100deg=0.25N•m/deg).
The fastening operation is ended when the measurement value of each rate falls outside the the high and
low limit ranges.
The start torque (angle) and end torque (angle) of the respective rates can be set freely without any relation
to the order of the rates and the set values of the other rates.
