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.

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.
Parameters:
D: Measuring axis – axis in which the measurement is to be
made
K: Incr. meas path w/ Ri. (the algebraic sign determines the
probing direction) – maximum measuring path for probing
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: Err. 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 – 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 (machine-dependent)
Orient the touch probe in the programmed probing direction
before each probing operation.
P: PRINT outputs
0: OFF – do not display measuring results
1: ON – display measuring results on the screen
H: INPUT instead of measure
0: Standard – obtain measured values by probing
1: PC test – simulate touch probe cycle on the programming
station
