I am being asked to load a twin spindle lathe with identical tools to cut a production part, and minimize operator interaction with the machine. I understand sub program loops, but this is quite different than anything I have attempted in the past.

The request is to run 30 cycles with tool 1, and then switch to tool 2, run 30 more cycles, and continue through the entire loaded turret. The machine has a Fanuc O series control.

Thanks in advance for any input.

First thing to know is "do you have macro capability?" in MDI, input
#100=1 eob and press cycle start.

I attempted that, and the control won't even take the # sign. This machine is an obsolete Doosan that should probably be in a scrapyard. I'm just going to assume it isn't Macro capable.

Thanks,

Then here's what I suggest:

Create your program, end it with M99

Run a program as a master, and have one line:

M98P1000L30

and end with
M30
%

where P1000 refers the the original program name (I used O1000, and P1000 refers to that program as a sub-program).

The "L" is how many times the sub-program runs before stopping

When the program is done running, edit the O1000 program to use the next tool.

Sorry I couldn't be more helpful, but without macro capability....

By the way... your M98 may have to be different. Refer to your manual, if you have one.
