Fixed point calibration

If you want to use a fixed point as the reference point in manual measurement of the tool length,
you must first determine the position of the fixed point relative to the machine zero.
Test socket
You can use a mechanical test socket as the fixed point, for example. Mount the test socket
on the machine table in the machining space of the machine. Enter zero as the distance.
Distance gauge
However, you can also use any fixed point on the machine in combination with a distance
gauge. Enter the thickness of the plate as "DZ".
To calibrate the fixed point, use either a tool whose length is known (i.e. the tool length must
be entered in the tool list) or the spindle directly.
The position of the fixed point may have already been determined by the machine
manufacturer.

3. Press the "Radius manual" or "Diam. manual" softkey.
4. Select the cutting edge number D and the the number of the replacement
tool ST.
5. Approach the workpiece in the X or Y direction and perform scratching
with the spindle rotating in the opposite direction.
6. Specify the setpoint position X0 or Y0 of the workpiece edge.
7. Press the "Set radius" or "Set diam." softkey.
The tool radius or diameter is calculated automatically and entered in the
tool list.
