G83 Deep hole peck drilling cycle
Centroid CNC12 Acorn G-code · Mill, Lathe
On mills: Deep hole peck drilling cycle
Drills in pecks of Q, rapids fully out to R after each peck, then rapids back down to a clearance above the last depth set by parameter 83.

Addresses
| Address | What it does |
|---|---|
X Y | Hole position |
Z | Hole bottom |
R | R plane |
Q | Peck depth |
L | Dwell at final depth |
F | Feed rate |
How it works
Modal, canned cycle. Cancel with G80.
Example program
T1 M6 ; LOAD TOOL 1, Z GOES HOME FIRST
G54 G0 X0 Y0 ; WORK OFFSET 1
S2000 M3
…
The full 8-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Set the rapid down clearance with G10 P83 R before the cycle. Otherwise parameter 83 is used.
- Leave L out if you want no dwell. L0 still dwells briefly.
- Q follows the implied decimal rules of parameters 245 and 246. Always type a decimal point.
On lathes: Deep hole peck drilling cycle
Drills on center in pecks of Q, rapids out to R after each peck, and rapids back to a clearance above the last depth from parameter 83.

The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Keep X0 unless the lathe has a C axis and live tooling.
- Set the clearance with G10 P83 R or parameter 83 is used.
