Setting data:SD42930 $SC_WEAR_SIGN is enabled in N90, i.e. the wear must be evaluated
with a negative sign. The compensation is vectorial (<CorComp> = 1), and the compensation
vector must be added to the wear (<CorMode> = 1). The geometrical relationships in the Z/X
plane are shown in the diagram below:

The geometry component of the tool remains unchanged due to <CorMode> = 1. The
compensation vector defined in the WCS (rotation around the y axis) must be included in the
wear component such that the total tool length in Fig. 3 refers to point P
2
. Therefore, the
resulting wear component of the tool is given by the distance of the two points P
1
and P
2
.
