or automatically with tool probes.
Turning tools
You can specify the tool offset data, i.e. the length, either manually or automatically using a
tool probe.
Logging measurement results
After you have completed the measurement, you have the option to output the displayed values

Measuring a tool manually

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.
You specify the position of the workpiece edge during the measurement.
Note
Lathes with B axis
For lathes with a B axis, execute the tool change and alignment in the T, S, M window before
performing the measurement.
