For wheel having a free contour, the user is always responsible for the cutting edges. Only
when a wheel is newly created or for deleted wear values, the cutting edge values are set by
default once, depending on the dressing angle. The default setting is done for angle = 0, like
for a simple vertical wheel, i.e. the odd cutting edges (D1, D3, D5) are on the left-hand side
and the even cutting edges (D2, D4, D6) on the right-hand side, taking into account the en-
tire wheel width.
The default setting for inclined wheels is arranged so that always all reference points are
identical. There is no distinction between left-hand and right-hand sides. In his/her DIN-ISO
dresser program, the user can define new cutting edges. For this, the NC syntax must be fol-
lowed. Any changes will be accepted only after the first complete dressing stroke and not
while shaping. Reference points are compensated as it is done for standard wheels.
Diameter and width monitoring will also be active only after both diameter and wear are in-
cluded in the particular D number. Thus the user can modify additional reference point in the
free contour. However, the left-hand and right-hand cutting edges regime must be main-
tained since the compensations are always taken into account (left-hand side negative, right-
hand side positive) as they are for standard wheels.
