TOLERANCE (Cycle 32)
Fast contour milling is adapted to suit both the TNC and
your machine by the machine manufacturer. Your
machine manual provides more detailed information.
The TNC automatically smoothens the contour between two path
elements (whether compensated or not). The tool has constant
contact with the workpiece surface. If necessary, the TNC
automatically reduces the programmed feed rate so that the
program can be machined at the fastest possible speed without
+jerk+. As a result the surface quality is improved and the machine
is protected.
A contour deviation results from the smoothing out. The size of this
deviation (tolerance value) is set in a machine parameter by the
machine manufacturer. You can change the pre-set tolerance value
with Cycle 32 (see figure at top right).
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 Cycle 32 reactivates the
pre-set tolerance:
