How do the F and A variables work?

[camtd]

Can anyone explain how the following work together? Is there something that is programmed at the Fanuc control that is not in this program?

Thank You

The F and A variables assign a value to variable #9 and # 1, respectively. F is the 9th letter in the alphabet, and A is the first. When you have a value passed through on the G65 line, it can be used for ANYTHING in the sub-programs, like X#9 or G#9. In your case F is used to pass a value for feedrate (F#9) and A is used to pass a value for another feedrate (F#1).

[sinha_nsit]

And when a macro calls another macro (which is called a nested macro), a new set of local variables (#1, #2 etc) are used for the nested macro.

Beege and Sinha hit it on the head. The first line of your program N190 calls program 2353 and when it calls that program #9 is set to 1.5 (F1.5) and #1 is set to 2.9 (A2.9). Now in the program at line N40 your feedrate says F#9, well #9 is set to 1.5 so when the program reads this line it will read F#9 as F1.5

The main reason this is usefull is because if you wanted to change the feed from 1.5 to say 3.5 you only have to change the F1.5 in line N190 instead of having to change it at every feed call in the program.

So if in the main program I put B5.0 then when I go to my subprogram and put
F#2 that will give my feedrate 5.0

If that is correct? I think I get that part now.

Can anyone recommend a verifier to view and help create parametric code?

I have found this one but did not get a price yet

Thank You helping past this sticking point.

[sinha_nsit]

Since I am a teacher, I always emphasize use of correct terms.
A "subprogram" is not same as a "macro."
A macro is called by G65 (plus some other methods), and data can be passed on for use inside it.
A subprogram is called by M98 (plus some other methods), and data cannot be passed on.
A macro has its own set of local variables.
A subprogram uses the variables of the calling program.

Naturally, I would deduct a few marks for this statement (even though what you have in your mind is absolutely correct):
"So if in the main program I put B5.0 then when I go to my subprogram and put
F#2 that will give my feedrate 5.0"

You have to accept me as I am. Some "stupid" teachers are like me only.

Bingo. Absolutely right!!

Sinha….I accept you as you are . I actually learn quite a lot from you. I have always been more hands on along with picking things up quickly and retaining it. However I never retained the proper verbiage of things. So I usually sound like an idiot when talking about a topic to say a “teacher” but I always knew what I was talking about (if that makes any sense). Basically I could never tell you why we had to do something a particular way but I knew that we had to.
