_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
