The PLANE function: Tilting the working plane (software option 8) 12.2
Defining the working plane with the spatial angle:
PLANE SPATIAL
Application
Spatial angles define a working plane using up to three rotations
of the workpiece coordinate system; two perspectives that have
always the same result are available for this purpose.
Rotations about the untilted coordinate system:
sequence of the rotations is first around the machine axis A,
then around the machine axis B, and then around the machine
axis C.
Rotations about the respectively tilted coordinate system:
The sequence of rotations is 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.
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 G80 if the entries
in Cycle G80 are defined as spatial angles on the
machine side.
