The result of transformations built up on each other
depends on the programming sequence.
In every coordinate system, program only the specified
(recommended) transformations. This applies to both
setting and resetting the transformations. Any other use
may lead to unexpected or undesired results. Please
observe the following programming notes.
Programming notes:
Transformations (mirroring and shifting) that are
programmed before the
PLANE
functions (except
for
PLANE AXIAL
) will change the position of the tilt
datum (origin of the working plane coordinate system
WPL-CS) and the orientation of the rotary axes
If you just program a shift, then only the position
of the tilt datum will change
If you just program mirroring, then only the
orientation of the rotary axes will change
When used in conjunction with
PLANE AXIAL
and Cycle 19, the programmed transformations
(mirroring, rotation and scaling) do not affect the
position of the tilt datum or the orientation of the
rotary axes
Without active transformations in the workpiece
coordinate system, the position and orientation of
the working plane coordinate system and workpiece
coordinate system are identical.
There are no transformations in the workpiece
coordinate system on 3-axis machine tools or with pure
3-axis machining. The
BASE TRANSFORM.
values of the
active line of the preset table have a direct effect on the
working plane coordinate system with this assumption.
Other transformations are of course possible in the
working plane coordinate system.
