Lathe with fanuc control, need help

[Adaware]

I need som starting help with Fanuc controll. Have used Okuma a long time ago and have forgotten what the programs looked like, g-codes and so on. It's a old Fanuc controll, the lathe is from year 2000 or so.

What i need is something i can refresh my memory with if you can help me?


Step one:
Say that i got a steel axle that is 60mm in diameter. I want to remove 10mm of the end to make it shorter. I want to use a cycle of some sort where i can use the T0202 tool as to roughcut and T0303 as finishcut.


Step two:
Next i want to turn the piece down from 60 to 40mm, 100mm invards. Roughcut and finishcut with a cycle. Same tools as step one.


Step three:
I want to use the subspindel to drill a hole 50mm deep in the center of the piece and i also want to tap (taper?) the hole with m10x1, 40mm deep . I know i can drill the hole in the normal way with rotating piece and a tool that is locked, but i remember how i did it that way so i want it the sub-spindel way
Tap is T0505
Drill is T0606


I think this is enough to start with. Maybe i will post something later asking for more.
Appreciate your help

Did not understand step 3? Did you want rotary tools? need list of M-codes for your specific machine to do that. What kind of machine is it? Brand and model?

[Adaware]

By sub-spindel i mean rotary tools of course. Sorry, bad language of me there
I don't know the M codes right now because i could not find the manual. Can you just write a M code so i can change it later when i find it out?


I didn't follow you completely on the program you wrote so i will ask in a different way so can i understand it better.

Here's something from a program i wrote in the Okuma i used before;

What do i have to do to make it work in Fanuc?
The cycle is in the end as you can see and i would like to have it there since it's easy to find when i'm changing values :P

Thanks for you help
