Examples
Example 1: Switching two axes alternating as geometry axis
A tool slide can be traversed using channel axes X1, Y1, Z1, Z2:
The geometry axes are configured so that after powering-up, initially Z1 is effective as 3rd
geometry axis under the geometry axis name "Z" and together with X1 and Y1 forms the
geometry axis group.
Axes Z1 and Z2 should now be used, alternating, as geometry axis Z in the part program:

N100 GEOAX(3,Z2)
878
Function for switching geometry axes.
Note:
GEOAX() without parameter specification activates the basic configuration of the
geometry axes parameterized in the machine data again.
Number of the geometry axis that is to be replaced by the specified channel axis.
Range of values: 0, 1, 2, 3
Note:
0: The specified channel axis is removed from the geometry axis group without
being replaced
1: 1. geometry axis ≙ coordinate axis X (abscissa) of the WCS
2: 2. geometry axis ≙ coordinate axis Y (ordinate) of the WCS
3: 3. geometry axis ≙ coordinate axis Z (applicate) of the WCS
