7.7 Chained transformations
SW 5 and higher supports
two
transformations one
after the other, such that the motion elements for the
axes from the first transformation are input data for
the chained second transformation. The motion
elements from the second transformation are
effective for the machine axes.
•
With SW 5
,
the chain can contain
two
transformations.
•
The
second
transformation must be "
Inclined
axis
" (TRAANG).
•
The first transformation can be any of the
following:
–
Orientation transformations (TRAORI),
incl. universal milling head
−
TRANSMIT
−
TRACYL
−
TRAANG
Applications
−
Grinding contours that were programmed as side
line of a cylinder operation (TRACYL) using an
inclined grinding wheel e.g. tool grinding.
−
Finish cutting of a contour which is not round and
which was generated with TRANSMIT using an
inclined grinding wheel.
Prerequisite for using the activation command for a
chained transformation is that the individual
transformations to be chained to one another and
the chained transformation to be activated are
defined by means of machine data.
The supplementary conditions and special cases
specified in the individual descriptions for the
transformations also apply to a chained
transformation.
