FIG. 6-2-4a Integrated Torque Rate Method Incremental Sampling
If no judgment is desired for any or all stages, the high and low limit values should be deleted
from the PARAMETER SET screen by first selecting the item, then depressing the DEL key
on the keyboard. Upon completion of the fastening process, the System will output the
highest and lowest incremental torque rate value measured during each stage. These values
will be output as 1st, 2nd, and 3rd RATE HIGH and LOW.
3rd Rate High
Maximum 3rd Torque Rate
3rd Rate Low
Minimum 3rd Torque Rate
2nd Rate High
Maximum 2nd Torque rate
2nd Rate Low
Minimum 2nd Torque Rate
1st Rate High
Maximum 1st Torque Rate
1st Rate Low
Minimum 1st Torque Rate
NAME AS OUTPUT
DATA
For all control operations the High and Low Torque Rate limits are set by determining the
acceptable limits from a study of known good and bad assemblies.
