Defining the machining plane with space angles:
PLANE SPATIAL
Application
Spatial angles define a working 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.
Parameter description for the positioning behavior: See
"Specifying the positioning behavior of the PLANE
function" on page 316.
