How can I look at the G80 cycles on a 31i model B?
I can't find them in the "MTB" folders. Anybody know how to do this?

I meant one of the G80 canned cycles. G84, for instance. I want to see how Fanuc programs a G84 canned cycle.

Hi ezzywave,
Just like most Fanuc's, if you want Rigid Tapping:
( f.e. TAP M8X1.25 Metric )
G95 ( MM/REV )
M29 S500
G84 Z-15. R5. F1.25
G80
G94 ( MM/MIN )
or only G94 mode:
G94 ( MM/MIN )
M29 S500
G84 Z-15. R5. F625 ( FEED = SPEED X PITCH = 500X1.25 )
G80
Check here for the Fanuc 30i-31i-32i Model B Operators Manual.

If you are asking about live-tool canned cycles on a lathe, here is a resource.
Re: How can I look at the G80 cycles on a 31i model B?
Like how to "program" it or how Fanuc makes it work under the hood?
look in the manual posted for the former
The latter is in the software and cannot be seen, that I know of.

Yes! I want to see "how Fanuc makes it work under the hood"!
With a G&L 8000 control you can enter a password which will allow you to view and edit all the G80 thru G89 cycles and the probing cycles. The G&L G84 cycle has 8(?) lines and many M codes.
I want to know how the G84 cycle coordinates the spindle rotation with the tapping axis. Or single point threading on a cnc lathe.
Re: How can I look at the G80 cycles on a 31i model B?
I am fairly certain that it is handled differently on the Fanuc from the G&L. If no one chimes in you can always call Fanuc.
Your G&L sounds like they are using macro calls for those cycles,from a Fanuc viewpoint. And Fanuc allows macro calls from G code but I think the classic canned cycle numbers are verboten.
I think Canned cycles are baked in at a much lower level than even the PMC or Ladder. You can alter several things about them with parameters but beyond that I couldnt tell you,
