I can't find them in the "MTB" folders. Anybody know how to do this?

For what reason would you need to look at a G80, a G80 is used to cancel a canned cycle it has no other purpose

[ezzywave]

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

This help ya?

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.

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.

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,
