G32 Single pass thread cutting
Mazak (EIA) G-code · Lathe
Cuts one thread pass with the feed locked to the spindle. F is the lead. You program every pass, so G92 or G76 is usually easier.
Format
G32 X(U) Z(W) F
Addresses
| Address | What it does |
|---|---|
X Z | End point of the pass |
F | Thread lead, inches per rev |
How it works
Modal, group 01.
Example program
T0303 (OD THREAD TOOL)
G97 S800 M03 (CONSTANT RPM)
G00 X.73 Z.25 (START OF PASS 1)
G32 Z-.75 F.0625 (THREAD PASS, 16 TPI)
…
G97 S800 M03 (CONSTANT RPM)
G00 X.73 Z.25 (START OF PASS 1)
G32 Z-.75 F.0625 (THREAD PASS, 16 TPI)
…
The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Start Z far enough before the part for the axis to reach speed, at least 2 or 3 leads.
- Use G97 constant RPM. G96 changes the speed and ruins the thread.
