Example for a machine with a C rotary table and an A tilting table.
Programmed function: PLANE SPATIAL SPA+0 SPB+45 SPC+0
Selecting the type of transformation
(entry optional)
On machines with C-rotary tables, a function is available for specifying
the type of transformation:
8 COORD ROT specifies that the PLANE function should
only rotate the coordinate system to the defined
tilting angle. The rotary table is not moved; the
compensation is purely mathematical.
8 TABLE ROT specifies that the PLANE function should
position the rotary table to the defined tilting angle.
Compensation results from rotating the workpiece.

When the PLANE AXIS function is used, COORD ROT and
TABLE ROT
are nonfunctional.
