Measuring a tool with a tool probe

During automatic measuring, you determine the tool dimensions in the directions X and Z with
the aid of a probe.
You have the possibility of measuring a tool using a tool holder that can be orientated (tool
carrier, swivel).
The function "Measure with tool carrier that can be orientated" is implemented for lathes with
a swivel axis around Y and associated tool spindle. The swivel axis can be used to align the tool
on 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
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.
Adapting the user interface to calibrating and measuring functions
The corresponding windows can be adapted to the measurement tasks in order to
automatically measure tools.
The tool offset data is calculated from the known position of the tool carrier reference point and
the probe.
The following selection options can be switched-in or switched-out:
● Calibration plane, measurement plane
● Probe
● Calibration feedrate (measuring feedrate)

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.
