Retracting the geometry axes before swiveling
Figure 21-6 Dialog to select the type of retraction
Select the retraction variant in the input field: This is defined in the ONE MILLION and TEN
MILLION position of the system variable $TC_CARR37[n]:
● Retract axis Z
● Retract axes Z, XY
● Retract in the tool direction, maximum or incremental
NOTICE
Collision avoidance
Make sure that the tool and the workpiece cannot collide during swivelling when moving the
tool axes.
Retracting axis Z or retracting axes Z, XY is realized as an absolute machine position at the
values of parameters $TC_CARR38[n] to $TC_CARR40[n].
$TC_CARR38[n] Retraction position X
$TC_CARR39[n] Retraction position Y
$TC_CARR40[n] Retraction position Z
