Working plane coordinate system WPL-CS
The working plane coordinate system is a 3-D Cartesian coordinate
system.
The position and orientation of the working plane coordinate
system depend on the active transformations in the workpiece
coordinate system.
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.
In the working plane coordinate system the user defines the
position and orientation of the input coordinate system with use of
transformations.
Transformations in the working plane coordinate system:
Cycle 7 DATUM SHIFT
Cycle 8 MIRROR IMAGE
Cycle 10 ROTATION
Cycle 11 SCALING
Cycle 26 AXIS-SPECIFIC SCALING
PLANE RELATIVE
As a PLANE function, the PLANE RELATIVE is effective
in the workpiece coordinate system and aligns the
working plane coordinate system.
The values of additive tilting always relate to the current
working plane coordinate system.
The result of transformations built up on each other
depends on the programming sequence.
Without active transformations in the working plane
coordinate system, the position and orientation of the
input coordinate system and working plane coordinate
system are identical.
There are also 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
input coordinate system with this assumption.
