Hmmm,
My Hitachi Seiki VK45 with the spiffy Seicos II controller manual lists 20 codes not listed by EIA-274D G-code.
G302-305
G322-333
G130, G131
G501, G511

Lables them like GG326 = Square plane, 2-directional (what ever that is)

I am guessing software like Turbo CNC, Master Cam or what ever I choose will not generate those codes.

"What dey fo, an do ah need em?"
and
"how is ah posed to git dem dar CAM to make dat dar code?"

(grin)

Any Cam system with customizable post will be able to generate those codes. As for what they do, I can't help you there.

I am guessing that they are Seicos routines that could be duplicated in the standard G-code set but would perhaps perform various tasks with greater efficiency or reduce the number of blocks needed for a given task. If a post processor is a procedural program (computer code) then there would have to be a logical relationship between pre and post G-code. In other words,

N0001 G0 X0.4541 Y0.000 F20.0
N0002 G WHAT EVER
N0003 MORE G
N0004 MORE G
N0005 AND MORE G

EQUALS
