Please note while programming:
Danger of collision!
To prevent a collision between the touch probe and the
workpiece, enter a low estimate for the nominal diameter
of the pocket (or hole).
If the dimensions of the pocket and the safety clearance
do not permit pre-positioning in the proximity of the touch
points, the TNC always starts probing from the center of
the pocket. In this case the touch probe does not return to
the clearance height between the four measuring points.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
The smaller the angle, the less accurately the TNC can
calculate the circle center. Minimum input value: 5°.
