Note:
Cylindrical grinding begins with S2.
Flat grinding begins with S1.
The conversion is done internally, for an entered value of 1.
For standard wheels (vertical and inclined), the D numbers are allocated a fixed meaning
(refer to the "compensation values" figure below). Based on the geometry data, this
allocation is always set by default for setting up and dressing.
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 made for angle = 0, in
the same way as 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 entire 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. The user has the
option of redefining the cutting edges in a dressing subprogram. For this, the NC syntax
must be followed. 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
included 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
maintained since the compensations are always taken into account (left-hand side negative,
right-hand side positive) as they are for standard wheels.
