G32 Single thread pass
Centroid CNC12 Acorn G-code · Lathe
Cuts one threading move locked to the spindle encoder. X and Z are the end point and F or E is the lead. You program each pass and each retract yourself.
Format
G32 X Z F or E
Addresses
| Address | What it does |
|---|---|
X Z | End point of the thread pass |
F | Thread lead per rev |
E | Thread lead, same as F |
How it works
Modal while threading.
Example program
G20 G99 G40 G97 ; INCH, FEED PER REV, RPM MODE
T0101 ; TOOL 1 WITH OFFSET 1
G97 S600 M3 ; THREAD IN RPM MODE
G0 X1.5 Z.2 M8 ; START POINT
…
T0101 ; TOOL 1 WITH OFFSET 1
G97 S600 M3 ; THREAD IN RPM MODE
G0 X1.5 Z.2 M8 ; START POINT
…
The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- G32 cuts only the thread move. Program the infeed, retract and return blocks yourself, or use G92 or G76.
- Start far enough off the part for the axis to reach speed.
