The G33 thread cutting mode can cut straight, tapered, face, and multistart
threads that have constant thread leads (use G34 to cut threads that do not
have a constant lead). The G33 thread cutting mode is a mode, not a cycle
and does not generate any extra motion blocks. This mode synchronizes
the thread cutting tool motion with the spindle to allow programming
multiple passes over the same threads.
