5.2 Turning cycles in CYCLE mode
Function
If the soft key "Stop Turn CD" is selected, then the cycle is stopped
after the thread change depth is reached and the thread is machined
(e.g. for measuring the thread depth).
To continue the cycle, press the NC Start key.
If the soft key "Noncut" is selected, no further cutting depth infeed
takes place, e.g. for smoothing the flanks.
If the soft key "Single cycle" is selected, only one thread cut is
executed per thread.
The next thread cut takes place with NC Start.
If the "Single block" soft key (PROGRAM mode) is selected, the
thread is fully machined.
The NC stop key can be pressed at any time to interrupt tool feed. An
NC Stop during thread cutting triggers a retraction from the thread
cutting. With NC Start you can continue machining from the start point
where the thread cutting was interrupted.
