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 Global Program Settings function (option
44) additionally provides the Rotation (WPL-CS)
transformation. This transformation is added to the
rotation (Cycle 10 ROTATION) that is defined in the NC
program.
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.
