Combining coordinate transformation cycles
When combining coordinate transformation cycles, always make sure
the working plane is swiveled around the active datum. You can
program a datum shift before activating Cycle 19. In this case, you are
shifting the machine-based coordinate system.
If you program a datum shift after having activated Cycle 19, you are
shifting the tilted coordinate system.
Important: When resetting the cycles, use the reverse sequence used
for defining them:
Automatic workpiece measurement in the tilted
system
The TNC measuring cycles enable you to have the TNC measure a
workpiece in a tilted system automatically. The TNC stores the
measured data in Q parameters for further processing (for example,
for printout).
