8 Measuring axis (1...3: 1=reference axis) Q272:
Axis in which the measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
3: Touch probe axis = measuring axis
8 Traverse direction Q267: Direction in which the
probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction
8 Datum number in table Q305: Enter the number in the
datum or preset table in which the TNC is to save the
coordinate. If you enter Q305=0, the TNC
automatically sets the display so that the new datum
is on the probed surface.
8 New datum Q333 (absolute): Coordinate at which the
TNC should set the datum. Basic setting = 0
8 Measured-value transfer (0, 1) Q303: Specify
whether the determined datum is to be saved in the
datum table or in the preset table:
-1: Do not use. See “Saving the calculated datum,”
page 64
0: Write determined datum in the active datum table.
The reference system is the active workpiece
coordinate system.
1: Write determined datum in the preset table. The
reference system is the machine coordinate system
(REF system).
