* Value of the chaining parameter if the compensation parameter is to be chained.
With this parameter it is possible to define which offset value is used
for grinding wheel surface speed, tool monitoring and centerless
grinding. The value always refers to cutting edge D1.

Length 1 (geometry + wear + base, depending on tool type)
\$TC_TPG9 = 4

\$TC_TPG9 = 5
Length 3 (geometry + wear + base, depending on tool type)
\$TC_TPG9 = 6
*: The tool parameter of cutting edge 2 is chained to the parameter of
cutting edge 1 (see tool-specific grinding data \$TC_TPG2, chain rule).
Here, typical chains are shown and the associated place value is
specified in brackets.
This parameter contains the number of the spindle to which the
monitoring data and GWPS refer.
This parameter defines which tool parameters of the right wheel edge
(D2) and left wheel edge (D1) must be chained (see TOA data). If the
value of one of the chained parameters is changed, it is then
automatically included in the chained parameter.
It must be noted that the minimum grinding wheel radius must be
specified in the Cartesian coordinate system for an inclined grinding
wheel. The length compensations always specify the distances
between the tool holder reference point and the tool tip in Cartesian
coordinates.
