Defining the machining plane with spatial 
angles: PLANE SPATIAL
Function
Spatial angles define a working plane using up to three rotations of the 
coordinate system; two perspectives that have always the same 
result are available for this purpose.
Rotations about the machine-based coordinate system:
The sequence of the rotations is as follows: First around the 
machine axis C, then around the machine axis B, and then around 
the machine axis A.
Rotations about the tilted coordinate system:
The sequence of rotations is as follows: First around the machine 
axis C, then around the rotated axis B, and then around the rotated 
axis A. This perspective is usually easier to understand, because one 
rotary axis is fixed so that the rotations of the coordinate system are 
easier to comprehend.
Before programming, note the following
You must always define the three spatial angles SPA, SPB, 
and SPC, even if one of them = 0.
This operation corresponds to Cycle19 if the entries in 
Cycle 19 are defined as spatial angles on the machine side.
Parameter description for the positioning behavior: See 
"Specifying the positioning behavior of the PLANE 
function" on page 430.
