Activating the datum from the preset table in an NC program
To activate datums from the preset table during program run, use
Cycle 247. In Cycle 247 you define the number of the datum that you
want to activate (see “DATUM SETTING (Cycle 247)” on page 462).
When activating a datum from the preset table, the TNC
resets all coordinate transformations that were activated
with the following cycles:
„ Cycle 7, Datum Shift
„ Cycle 8, Mirroring
„ Cycle 10, Rotation
„ Cycle 11, Scaling
„ Cycle 26, Axis-Specific Scaling
However, the coordinate transformation from Cycle 19,
Tilted Working Plane, remains active.
