Grinding-specific tool offset and tool monitoring (W4)
18.2 Tool offset for grinding operations
Spindle number $TC_TPG1
Number of programmed spindle (e.g. grinding wheel peripheral speed) and spindle to be
monitored (e.g. wheel radius and width).
Chain rule $TC_TPG2
This parameter is set to define which tool parameters of tool edge 2 (D2) and tool edge 1
(D1) have to be chained to one another. When the setpoint of a chained parameter is
modified, the value of the parameter with which it is chained is modified automatically.

Example of parameter chain:
Lengths 1, 2 and 3 of the geometry, the length wear and the tool base/adapter dimensions of
lengths 1, 2 and 3 on a grinding tool (T1 in the example) must be automatically transferred.
