Yield Control
This strategy detects the yield of the fastener and reports
the torque and angle that resulted from the fastening
event.
Controlling by detecting Yield is very beneficial on joints
where clamp load varies greatly relative to final torque.
This strategy can be used alone or combined with other
strategies as steps in a parameter set. As an example, a
common fastening strategy could be three steps:
Torque Stage – To set a minimum threshold
Yield Stage – To control clamp load
Angle Stage – To attain a specific bolt stretch above
Yield
Yield Target % is programmable with a default setting
of 50%.
The lower this value, the more sensitive the strategy will
be. Too low could cause early and false detection.
The higher this value, the less sensitive the strategy will be. A more pronounced change in slope
is required for the yield to be determined.
The measurement is joint specific and 0% when parallel to the slope determined to be the elastic
range and 100% is when the slope is horizontal.
Joint Rate parameters have default settings of 5 samples every 20 degrees. This resolution can
be adjusted if needed.
