As opposed to example 6, parameter _CORCOMP = 3, and so the _GEOAX parameter can
be omitted. The value contained in _CORVAL[0] now acts immediately on the tool length
component L1, the rotation in N80 has no effect on the result, the wear components in
$TC_DP12 are included in the geometry component together with _CORVAL[0], with the result
that the total tool length is stored in the geometry component of the tool, due to $TC_DP13,
after the first SETTCOR call in N100.

In N90 the setting data is enabled:
SD42930 $SC_WEAR_SIGN (sign of wear)
i.e. the wear must be valued with a negative sign.
The compensation is vectorial (_CORCOMP = 1), and the compensation vector must be added
to the wear (_CORMODE = 1). The geometric conditions in the Z/X plane are shown in the
figure below:
