Effect with a free rotary axis
Programming notes
For the positioning behavior with the COORD ROT
and TABLE ROT transformation types, it does not
matter if the free rotary axis is a table or 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 with Cycle 10 ROTATION

If no transformation type was specified, the control
uses the COORD ROT transformation type for the PLANE
functions

Multiple-Axis Machining | The PLANE function: Tilting the working plane (option 8)
The control positions the free rotary axis to 0
The control aligns the working plane coordinate
system according to the programmed spatial
angle
SPA and SPB equal to 0
SPC equal or unequal to
The control aligns the free rotary axis according
to the programmed spatial angle
The control aligns the working plane coordinate
system according to the basic coordinate
system
At least SPA or SPB unequal to
SPC equal or unequal to
The control does not position the free rotary
axis. The position before tilting the working
plane is maintained
Because the workpiece was not positioned,
the control aligns the working plane coordinate
system according to the programmed spatial
angle
