Effect with a free rotary axis
Programming notes
For the positioning behavior with the COORD ROT
and TABLE ROT transformation types, it makes no
difference whether the free rotary axis is a table axis
or a head axis.
The resulting axis position of the free rotary axis
depends on an active basic rotation, among other
factors.
The orientation of the working plane coordinate
system also depends on a programmed rotation; for
example, by means of Cycle 10 ROTATION.

Multiple-axis machining | The PLANE function: Tilting the working plane (option 8)
The control positions the free rotary axis to 0
The control orients the working plane
coordinate system in accordance with the
programmed spatial angle
SPA and SPB equal to 0
SPC equal or unequal to 0
The control orients the free rotary axis in
accordance with the programmed spatial
angle
The control orients the working plane
coordinate system in accordance with the
basic coordinate system
At least SPA or SPB unequal to 0
SPC equal or unequal to 0
The control does not position the free rotary
axis. The position prior to tilting the working
plane is maintained
Since the workpiece was not positioned, the
control orients the working plane coordinate
system in accordance with the programmed
spatial angle
