_CORCOMP is 3, as in the previous example, but the compensation is now effective on the
geometry axis with index 0 (X axis). The tool components L3 are assigned to this geometry
axis due to G17 with a milling tool. Calling SETTCOR thus does not affect tool parameters
$TC_DP3 and $TC_DP12. 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 G18 is active. Since "_CORRMODE = 3", the tool wear in the direction of the X
axis of the WCS must become zero once N100 has been executed. The contents of the
relevant tool parameters at the end of the program are thus:
$TC_DP3[1,1]
: 21.830 ; Geometry L1
$TC_DP4[1,1]
: 21.830 ; Geometry L2
$TC_DP12[1,1]
: 2.500 ; Wear L1
$TC_DP13[1,1]
: -4.330 ; Wear L2
