A contour deviation results from the smoothing. The size of this
deviation (tolerance value) is set in a machine parameter by the
machine manufacturer. With Cycle 32, you can change the pre-set
tolerance value and select different filter settings.
Before programming, note the following:
Cycle 32 is DEF active which means that it becomes
effective as soon as it is defined in the part program.
You can reset Cycle 32 by defining it again and confirming
the dialog question after the tolerance value with NO
ENT. Resetting reactivates the pre-set tolerance.
In a program with millimeters set as unit of measure, the
TNC interprets the entered tolerance value in millimeters.
In an inch program it interprets them as inches.
If you transfer a program with Cycle 32 that contains only
the cycle parameter Tolerance value T, the TNC inserts
the two remaining parameters with the value 0 if required.
