G83 Peck Drilling Cycle (Deep Hole) for Haas CNC



G83 Deep Hole Peck Drilling Canned Cycle Explanation

G83 Peck Drilling Cycle G-code is modal so that it is activated every X and/or Y axis move, and it will rapid to that position and then cause this canned cycle (Drilling) to be executed again, until it’s canceled (G80).

Haas CNC control gives us more flexibility when dealing with Deep Hole Peck Drilling (G83).

Haas CNC has two formats of G83 Deep Hole Peck Drilling Cycle.

The first and widely used one is just like the Fanuc CNC control format as stated below
This G83 drilling cycle format is briefly described here G83 Peck Drilling Cycle (Deep Hole) for Fanuc

G83 Peck Drilling Cycle Format

G83 X_ Y_ Z_ R_ Q_ F_;
X Y – Hole position data
Z – Z-depth (feed to Z-depth starting from R plane)
R – Position of the R plane
Q – Depth of cut for each cutting feed (depth of each peck)
F – Cutting feedrate

The second format for Haas CNC G83 Deep Hole Peck Drilling Cycle is below

G83 Peck Drilling Canned Cycle Format – I J K Options

G83 Peck Drilling Cycle with I J K Options

G83 Peck Drilling Cycle with I J K Options

G83 X_ Y_ Z_ I_ J_ K_ R_ F_;
X Y – Hole position data
Z – Z-depth (feed to Z-depth starting from R plane)
R – Position of the R plane
I – Size of first cutting depth
J – Amount to reduce cutting depth each pass
K – Minimum depth of cut
F – Cutting feedrate
The first pass will cut in by I, each succeeding cut will be reduced by amount J, and the minimum cutting depth is K.

Haas CNC G83 Deep Hole Peck Drilling Cycle Setting

Setting 22 – As the tool pecks deeper into the hole, with each peck it rapids out to the R-plane, and then back in to a constant specified distance above the bottom of the hole that was created by the previous peck. That specified distance is defined in Setting 22.
