Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment | Compensating workpiece

Please note while programming:

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°
Danger of collision!
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.
Make sure that there is no material in the pocket/hole
To prevent a collision between the touch probe and the
workpiece, enter a
the pocket (or hole).
Danger of collision!
Cycles for coordinate transformation must not be active during
execution of the touch probe cycles.
Do not activate the following cycles before using touch probe
cycles: Cycle 7 DATUM SHIFT,Cycle 8 MIRROR IMAGE, Cycle
10 ROTATION,Cycle 11 SCALING and 26 AXIS-SPECIFIC
SCALING
