Cylindrical grinding
202 Programming and Operating Manual, 07/2009, 6FC5398-4CP10-2BA0
Sequence of operations
When positioning the dresser in the X and Z directions, the starting position is offset by the
amount of the retraction travel in the positive X direction.
The wheel type (straight, inclined) selected for dressing depends on the entry in the tool-
specific wheel parameter TPC1.
The tool traverses in the +Z direction for dressing and, subsequently - depending on the
wheel type - in the –X direction. Thereafter, the wheel is retracted in the Z axis from the
dresser zero by the retraction travel. When using wheels with a corner radius, a chamfer or a
relief cut, these are machined at the path feedrate.
The starting position (see illustration) is also repeatedly approached at rapid traverse after
retraction in case of several dressing strokes. Dressing at the diameter can be selected to be
either by drawing or pushing, depending on the technology.
With each dressing stroke, the infeed is performed by the programmed dressing amount.
After dressing, the X axis is positioned at the X return position.

X_AB, Z_AB (dressing amount in X and Z)
The dressing amount is the amount by which the wheel is reduced in X or Z when dressing.
When using an inclined wheel, the dressing amount in Z is calculated using the wheel angle
and the X dressing amount.
FFW (retraction travel)
The FFW parameter specifies the retraction travel in both axes X and Z.
