Probing in C axis G765

Cycle G765 measures with the C 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 431.).

Cycle run
From the current position, the element to be probed is moved toward

the touch probe by a rotation of the C axis. When the workpiece

touches the stylus, the measured value is saved and the workpiece is

returned.
The control outputs an error message if the touch probe does not

reach any touch point within the defined measuring path.

Parameters

C

Incremental measuring path with direction: Measuring path of

the C axis (in degrees), starting from the current position. 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 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
