G92 Set current position / Single pass threading cycle
Centroid CNC12 Acorn G-code · Mill, Lathe
On mills: Set current position
Sets the current position to the given values in the active work offset only.
Format
Addresses
| Address | What it does |
|---|---|
X Y Z | New value for the current position |
How it works
Stays in effect in the active work offset until changed.
Example program
G92 X-10. ; CALL THIS POSITION X-10
G0 X0 ; MOVE TO NEW ZERO
Example is in inch. Check offsets and clearances first.
Watch out for
- G92 changes the work offset in the WCS table. Most shops prefer G54 to G59 or G52.
On lathes: Single pass threading cycle
One threading pass box cycle: rapid in, thread to Z, pull out with the chamfer from parameter 49, and rapid back. Repeat with a new X for each pass.
Format
Addresses
| Address | What it does |
|---|---|
X Z | Pass diameter and thread end |
R | Taper amount for a pipe thread |
F | Thread lead |
How it works
Modal while threading. Cancel with G80 or a motion code.
Example program
G97 S600 M3
G0 X1.1 Z.25 M8 ; START POINT
G92 X.97 Z-1.5 F.125 ; PASS 1
…
The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- The pull out chamfer is parameter 49 times the lead.
- For a multi start thread, shift the start Z by the lead divided by the number of starts.
