W4: Grinding-specific tool offset and monitoring functions - only 840D sl
18.2 Tool offset for grinding operations
Minimum wheel radius and width $TC_TPG3 $TC_TPG4
The limit values for the grinding wheel radius and width must be entered in these
parameters. These parameter values are used to monitor the grinding wheel geometry.
Note
It must be noted that the minimum grinding wheel radius must be specified in the Cartesian
coordinate system for an inclined grinding wheel. A signal is output at the PLC interface if the
grinding wheel width and radius drop below the minimum limits. The user can use these
signals to define his error strategy.
Current width $TC_TPG5
The width of the grinding wheel measured, for example, after the dressing operation, is
entered here.
Maximum speed and grinding wheel peripheral speed $TC_TPG6 $TC_TPG7
The upper limit values for maximum speed and peripheral speed of the grinding wheel must
be entered in these parameters.
Requirement: A spindle has been declared.
