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: "Universal tapping cycle G31", Page 347
G32 cuts a simple thread in any desired direction and position
Further information: "Single thread cycle G32", Page 352
G33 conducts a single thread cut. The direction of the single
thread cut is as desired
Further information: "Thread single path G33", Page 354
G35 cuts a simple cylindrical metric ISO thread without run-out
Further information: "Metric ISO thread G35", Page 356
G352 cuts a tapered API thread
Further information: "Tapered API thread G352", Page 357
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.
