Defining The Working Plane With The Spatial Angle: Plane Spatial - HEIDENHAIN TNC 620 User Manual

The PLANE Function: Tilting the Working Plane (Software Option 1) 11.2
Defining the working plane with the spatial angle:
PLANE SPATIAL
Application
Spatial angles define a working plane using up to three rotations
of the coordinate system; two perspectives that have always the
same result are available for this purpose.
Rotations about the machine-based coordinate system:
sequence of the rotations is first around the machine axis C,
then around the machine axis B, and then around the machine
axis A.
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, 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.
