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:
