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 show 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
