X, Y, Z (entry optional, other axes also possible):
For pallets and fixtures, the programmed coordinates are referenced
to the machine datum. For NC programs, the programmed
coordinates are referenced to the pallet or fixture datum. These
entries overwrite the datum that you last set in the Manual mode of
operation. With the miscellaneous function M104 you can reactivate
the datum that was last set. With the actual-position-capture key,
the TNC opens a window that enables you to have the TNC enter
various points as datums (see table below):
With the arrow keys and ENT, select the position that you wish to
confirm. Then press the ALL VALUES soft key so that the TNC saves
the respective coordinates of all active axes in the pallet table. With
the PRESENT VALUE soft key, the TNC saves the coordinates of the
axis on which the highlight in the pallet table is presently located.
Position Meaning
Actual values Enter the coordinates of the current tool position
referenced to the active coordinate system.
Reference
values Enter the coordinates of the current tool position
referenced to the machine datum.
ACTL measured
values
Enter the coordinates referenced to the active
coordinate system of the datum last probed in
the Manual operating mode.
REF measured
values
Enter the coordinates referenced to the machine
datum of the datum last probed in the Manual
operating mode.
If you have not defined a pallet before an NC program, the
programmed coordinates are then referenced to the
machine datum. If you do not define an entry, the datum
that was set manually remains active.
