Manually Measuring A Turning Tool (For Milling/Turning Machine) - Siemens SINUMERIK 840D sl Operating Manual

During calibration, the probe is withdrawn after the first probing, the spindle is rotated by 180°
and probing repeated. A mean value of two values is then determined and entered.
Note
Setting the protection level
The "Calibrate probe" function is only available if an adequate level of protection is set.
Please refer to the machine manufacturer's specifications.

Manually measuring a turning tool (for milling/turning machine)

When measuring manually, traverse the tool manually to a known reference point in order to
determine the tool dimensions in the X and Z directions. The control system then calculates
the tool offset data from the position of the tool carrier reference point and the reference point.
Reference point
The workpiece edge is used as the reference point when measuring length X and length Z.
The chuck of the main or counterspindle can also be used when measuring in the Z direction.

1. Move the calibration tool until it is approximately over the center of the
measuring surface of the tool probe.
2. Select operating mode "JOG" in the "Machine" operating area and press
the "Measure tool" softkey.
3. Press the "Calibrate probe" softkey.
4. Choose whether you want to calibrate the length only, or the length and
the diameter.
5. Click in the selection field "Spindle rotation" entry "Yes" if you want to
perform the "Calibration with rotation".
6. Press the <CYCLE START> key.
Calibration is automatically executed at the measuring feedrate. The dis‐
tance measurements between the machine zero and tool probe are cal‐
culated and stored in an internal data area.
