Probing in two axes G768
Cycle G765 measures the position programmed in the cycle in the Z/
Y plane and displays the measured values on the control screen. In
parameter NF you can additionally define the variables in which the
measuring results should be saved.
Cycle run
The touch probe moves from the current position toward the
measuring point. When the stylus touches the workpiece, the
measured value is saved and the touch probe is positioned back to the
starting point.
The control outputs an error message if the touch probe does not
reach any touch point within the defined measuring path.

Parameters
Z
Target point Z: Z coordinate of measuring point
Y Target point Y: Y coordinate of measuring point
V Retraction type
 0: Without: Only position touch probe back to the starting
point if the touch probe was deflected
 1: Automatic: Always position touch probe back to the starting
point
O Error evaluation
 0: Program: Do not interrupt program run, no error message
 1: Automatic: Interrupt program run and output error message
if touch probe is not deflected within measuring path
F Measuring feed rate: Feed rate for probing. If nothing is entered,
the measuring feed rate from the touch probe table is used. If
the entered measuring feed rate F is higher than the one in the
touch probe table, the feed rate is reduced to the value from the
touch probe table.
Q Tool orientation: Orient the touch probe in the programmed
probing direction before each probing operation (machine-
dependent function)
NF Result variable no.: Number of the first global variable in which
the result is saved (no entry = variable 810). The second
measurement result is saved automatically under the next
consecutive number.
P PRINT outputs
 0: OFF: Do not display measuring results
 1: ON: Display measuring results
H INPUT instead of measurement
 0: Default: Obtain measured values by probing
 1: PC test: Simulate probing cycle on the programming station
