DIN/ISO: G420)
Cycle run
Touch Probe Cycle 420 measures the angle that any straight surface
on the workpiece describes with respect to the reference axis of the
working plane.
1
Following the positioning logic (siehe „Executing touch probe
cycles” auf Seite 334), the TNC positions the touch probe at rapid
traverse (value from MP6150) to the programmed touch point
1
.
The TNC offsets the touch probe by the safety clearance in the
direction opposite to the defined traverse direction.
2
Then the touch probe moves to the entered measuring height and
probes the first touch point at the probing feed rate (MP6120).
3
Then the touch probe moves to the next starting position
2
and
probes the second touch point.
4
The TNC returns the touch probe to the clearance height and saves
the measured angle in the following Q parameter:

Q150
The measured angle is referenced to the
reference axis of the machining plane.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
If touch probe axis = measuring axis, set Q263 equal to
Q265
if the angle about the A axis is to be measured; set
Q263
not equal to Q265 if the angle is to be measured about
the B axis.
