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 an Z2 should now be used, alternating, as geometry axis Z in the part program:
