MP6507=1:
The measuring tolerance depends on the size of the tool
radius. This prevents the probe feed rate from being
decreased to zero when a tool with a large radius is being
measured. The TNC adjusts the measuring tolerance as

Displaying the results of tool measurement
In the program run modes of operation, you can select the TEXT / TOOL
PROBE STATUS screen layout. The TNC then displays the program text
in the left and the measuring results in the right screen window (see page
I-4). The measuring results that exceed the permissible wear tolerance
are marked with an asterisk (*I, and those that exceed the permissible
breakage tolerance are identified with the letter B.
