Cycle run
Touch Probe Cycle 1 measures any position on the workpiece in any 
direction.
1
The touch probe moves at rapid traverse (value from FMAX 
column) to the starting position 
1
programmed in the cycle.
2
Then the touch probe runs the probing process at the probing feed 
rate (column F). During probing the TNC moves simultaneously in 
2 axes (depending on the probing angle). The scanning direction is 
defined by the polar angle entered in the cycle.
3
After the TNC has saved the position, the probe returns to the 
starting point. The TNC also stores the coordinates of the touch 
probe position at the time of the triggering signal in parameters 
Q115 to Q119.

Danger of collision!
Pre-position the touch probe in order to avoid a collision 
when the programmed pre-positioning point is 
approached.
The probing axis defined in the cycle specifies the probing 
plane:
Probing axis X: X/Y plane
Probing axis Y: Y/Z plane
Probing axis Z: Z/X plane
