5.2 Turning cycles in CYCLE mode
The "Thread" cycle allows you to produce cylindrical/tapered external
and internal threads with a variable lead, as well as transversal
threads. The threads may be single or multi-turn.
Infeed is automatic. You can select one of two infeed variants, i.e.
constant infeed per cut and constant cutting cross-section.
Whether the thread is left-handed or right-handed is determined by the
rotational direction of the spindle and the feed direction.
This cycle can only be applied on machine tools that have a speed-
controlled spindle with position measuring system.
the menu "Directory" offers you the option Parts program manage-
ment. You can store parameterized dialog forms in this directory as a
file and later call them up again (see Section "Parts Program
