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 426.
