Switch-in tool monitoring by selecting a tool
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
A standard T number and standard D number can be set per machine data,
which do not have to be reprogrammed and are effective after power on/reset.
Example: All machining is performed with the same grinding wheel.
The machine data can be used to set that the active tool remains for a reset (see "Free D
number assignment, cutting edge number (Page 430)").
