5.5 Measuring with touch probe
cycles
Paraxial probing G764
Cycle G764 measures with the programmed axis and displays the
measured values on the control screen. The result of the
measurement is saved additionally in the variable #i99. (See "Touch
probe cycles for automatic operation" on page 429.)
Cycle run
From the current position the touch probe moves along the defined
measuring axis 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.
Example: G764 paraxial probing

Parameters
D
Measuring axis: Axis in which the measurement is to be made
K Incremental measuring path with direction (signed): Maximum
measuring path for probing. The algebraic sign determines the
probing direction.
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)
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
