Example for a machine with a rotary table C and a tilting table A.
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:
U 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.
U TABLE ROT specifies that the PLANE function should
position the rotary table to the defined tilting angle.
Compensation results from rotating the workpiece.

None A+0, C–135 + A+45, C+90
When the PLANE AXIAL function is used, COORD ROT and
TABLE ROT
are nonfunctional.
If you use the TABLE ROT function in conjunction with a
basic rotation and a tilting angle of 0, then the TNC tilts the
table to the angle defined in the basic rotation.
