PLANE SPATIAL
Function
Spatial angles define a machining plane through up to three rotations
around the fixed machine coordinate system. The sequence of
rotations is firmly specified: first around the A axis, then B, and then C
(the function corresponds to Cycle 19, if the entries in Cycle 19 are set
to space angles).
Before programming, note the following:
You must always define the three space angles SPA, SPB,
and SPC, even if one of them = 0.
The sequence of the rotations described above is
independent of the active tool axis.
