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 431.).

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

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 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
