Requirements
You can only activate tool monitoring if the tool-specific grinding data $TC_TPG1 to
$TC_TPG9 are set, see
/FB1/Function Manual Basic Functions; Tool Offset (W1).
According to the machine data settings, tool monitoring for the grinding tools (types 400-499)
can be automatically activated when the tool selection is activated.
Only one monitoring routine can be active at any one time for each spindle.
Geometry monitoring
The current wheel radius and the current width are monitored.
The set speed is monitored against the speed limitation cyclically with allowance for the
spindle override.
The speed limit is the smaller value resulting from a comparison of the maximum speed with
the speed calculated from the maximum wheel peripheral speed and the current wheel
radius.
Working without a T or D number
In the machine data, a default T and D number
