Calibration using a calibration sphere
For manual calibration using a calibration sphere, proceed as
follows:
In the
Manual operation
mode, position the ball
tip above the center of the calibration sphere
Select the calibrating function: Press the
Calibration of TS on a sphere
soft key
Enter the outside diameter of the ball
Enter the safety clearance
Enter the start angle
Enter the number of touch points
Select Length measurement, if applicable
If necessary, input the reference for the length
Probe: Press the
NC Start
key
The 3-D touch probe probes all required touch
points in an automatic probing routine and
calculates the effective ball-tip radius. If probing
from opposite orientations is possible, the control
calculates the center offset.
Check results
Press the
OK
soft key for the values to take effect
Press the
END
soft key to terminate the
calibrating function
The control logs the calibration process in the
TCHPRMAN.html file.
Refer to your machine manual.
In order to be able to determine ball-tip center
misalignment, the control needs to be specially prepared
by the machine manufacturer.
Displaying calibration values
The control saves the effective length and effective radius of the
touch probe in the tool table. The control saves the touch probe
center offset to the touch probe table in the columns
CAL_OF1
(main axis) and
CAL_OF2
(secondary axis). You can display the
values on the screen by pressing the
TCH PROBE TABLE
soft key.
Further information: "Touch probe table", Page 148
During calibration, the control automatically creates the
TCHPRMAN.html log file to which the calibration values are saved.
Ensure that the tool number in the tool table and the
touch-probe number of the touch-probe table match. This
is regardless of whether you want to use a touch-probe
cycle in automatic mode or in
Manual operation
mode.
