<CorComp> is "3", therefore, the wear value and compensation value are added to the
geometry component and the wear component is deleted.
The resulting total tool length is thus: L1 = 11.333 + 0.0 = 11.333

<CorComp> is "3", as in the previous example, but the compensation is now effective on the
geometry axis with index "0" (X axis), which for a milling tool, is assigned to tool component L3
due to G17. As a consequence, when calling SETTCOR, tool parameters $TC_DP3 and
$TC_DP12 are not influenced. Instead, the compensation value is entered in $TC_DP5.

The tool is a turning tool. A frame rotation is activated in N80, causing the basic coordinate
system (BCS) to be rotated in relation to the workpiece coordinate system (WCS). In the WCS,
the compensation value (N70) acts on the geometry axis with index 1, i.e. on the X axis because
