Fundamentals 3.1
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 preset line are directly affective
on the input coordinate system with this assumption.
