9.7 Measuring Tools with the TT 110 Touch Probe
MP6507=1: The measuring tolerance increases with increasing tool
radius. This ensures that a probing feed rate is maintained
even for large tool radii. The TNC changes the measuring
tolerance according to the following table:
Tool radius Measuring tolerance
Up to 30 mm MP6510
30 to 60 mm 2 • MP6510
60 to 90 mm 3 • MP6510
90 to 120 mm 4 • MP6510
MP6507=2: The probing feed rate remains constant, however the
measuring error grows in linear proportion to any increase
in tool radius:
Measuring tolerance =
where r = Tool radius [mm]
MP6510 = Maximum permissible measuring error
Displaying the results of measuring
With the STATUS TOOL PROBE soft key you can show the results of
tool measurement in the additional status display (in the machine operat-
ing modes). Measured values that have exceeded the permissible wear
tolerance are indicated with an asterisk
(∗).
