Thread cutting with endlessly rotating spindle

In the case of thread cutting with an endlessly rotating spindle (G33), the contouring motion is synchronized to the passage of the spindle rotation through zero. Therefore, the thread can also be cut in several, successive passes.

To achieve a good machining result and to minimize contour errors, feed forward control can be selected for the spindle and for the contouring axes.
