Figure 10-9: Changing the tolerance numerically
Enter the corrected values for the individual parameters.
In the case of force tolerances, you have the possibility to set individual
windows to "not active".
In the case of stroke tolerances, you have the possibility to transfer the
tolerance from the "Working Stroke" to the "Return Stroke" (or vice versa), or
to set the tolerance to "not active".
By using the "Not active" setting, you can hide tolerances (they will not be
taken into account by the quality evaluation) without deleting the tolerances.
Move tolerance data
The curve of the reference force curve shows a characteristic press process.
The length tolerances of the parts can offset the curve on the X axis in the
positive or negative direction.
To be able to monitor press processes of this type efficiently, the tolerances
must be offset as a function of the length of the components. This is done by
the "Move tolerance data" function.
The offset is determined via the intersection of the reference curve with a
stroke tolerance.
