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

Note
Tool measurement is only possible with an active tool.

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

During automatic measuring, you determine the tool dimensions in the X and Z axes using a
probe.
You have the possibility of measuring a tool using a tool holder that can be oriented (tool carrier,
swivel).
The function "Measure with orientable tool carrier" is implemented for lathes with a swivel axis
around Y and associated tool spindle. The swivel axis can be used to align the tool at the X/Z
level. The swivel axis can assume any position around Y to measure turning tools. Multiples
of 90° are permitted for milling and drilling tools. Multiples of 180° are possible when positioning
the tool spindle.
Note
Milling/turning machines with a B axis (only 840D sl)
For milling/turning machines with a B axis, execute the tool change and alignment in the T, S,
M window before performing the measurement.
Adapting the user interface to the calibrating and measuring function
The tool offset data is calculated from the known position of the tool carrier reference point
and the probe.
You can adapt the corresponding windows to the measurement tasks in order to automatically
measure tools.
The following selection options can be switched-in or switched-out:
● Calibration plane, measurement plane
● Probe
● Calibration feedrate (measuring feedrate)

10. Enter the position of the workpiece edge in X0 or Z0.
If no value is entered for X0 or Z0, the value is taken from the actual value
display.
11. Press the "Set length" softkey.
The tool length is calculated automatically and entered in the tool list.
Whereby the cutting edge position and tool radius or diameter are auto‐
matically taken into consideration as well.
