Selecting the type of transformation
(entry optional)
On machines with C-rotary tables, a function is available for specifying
the type of transformation:
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.
TABLE ROT specifies that the PLANE function should
position the rotary table to the defined tilting angle.
Compensation results from rotating the workpiece.
