4.19 Thread cycles

Overview of thread cycles

G31 machines single threads, successions of threads and multi-
start threads defined with G24, G34 or G37-Geo (FINISHED PART).
G31 can also machine a threading contour defined directly after
the cycle call and concluded by G80
Further information:
G32 cuts a simple thread in any desired direction and position
Further information:
G33 conducts a single thread cut. The direction of the single
thread cut is as desired
Further information:
G35 cuts a simple cylindrical metric ISO thread without run-out
Further information:
G352 cuts a tapered API thread
Further information:

Handwheel superimposition

If your machine features handwheel superimposition, you can overlap
axis movements during thread cutting in a limited area:
X direction: Maximum programmed thread depth depending on
the current cutting depth
Z direction: +/- a fourth of the thread pitch
Refer to your machine manual.
This function must be set up by your machine
manufacturer.
Remember that position changes resulting from
handwheel superimposition are no longer effective after
the cycle end or the Last cut function.
