Fanuc macro B thread....

wow...on topic..imagine that?
Im writing a macro for the milling dept that takes a program processed off
UG and runs the first tool in all the positions, then runs the second tool
in all the positions, etc... As opposed to run all tools position 1, then
run all tools position 2 etc...
The tuff part is the mills are always running, so im having trouble getting
debug time on the machines.
when i do get to the mill I need my proggy real close to good, because I
wont have the luxury of spending a lot of time debugging.
The machines are makinos, a few different models, all with the macro b
option and a hardrive (m198)
I downloaded a few simulators, and im still in the process of seeing if any
of those will help. so far no.
So I figured Id post it here and anybody with skills, or just hates me can
pick it apart and insult me.
Even spelling, be mean!!!
kind of a pre debug.
Here is the main proggy....
IF [#102 GT 8] GOTO 50
G00 G54.#101 X0. Y0.
M198 P#100
#101= #101 - 1
#102=#102 + 1
In the gcode sent from UG....
O0020 ;
IF [#102 > #103] GOTO 100
GOTO #102
****add this to top of program******
N1 T1
N2 T2
N3 T3
*****m99 at end of each toolchange and n numbers at toolchanges only******
N100 *
***add n100 before ending blocks*******
This is version 3, its 90% shorter than version 1.
If you have a better way, hell ill scrap the whole thing in the name of
Id love to have a version 4.
if someone gets to version 4, ill put their name on the first line of the
main program.
Youll be famous......kinda.

you're needlessly complicating things...
There's no need to use macro b for multiple fixturing, all you need is a 2 line sub program to update G54 coordinates for each fixture location that contains nothing but a g10 statement, (along with a subprogram containing the actual toolpath)

********** Thanks for the reply, but what im trying to do is reach into the gcode program and select tool one and run it thru all the positions. Then reach into the gcode again, and grab tool 2 and run it thru all the positions, etc... till all the tools have been ran. The current way is it calls up the program and runs all the tools on that first position, then runs all the tools on the next position. The owner hates all the toolchanges. 90 toolchanges as opposed to 9. Plus the added benefits of rpm control. Nothing worse than each position running from 2000 to 30000 rpm before it goes to the next position. the parts they are cutting (electrodes) are all over the place in x y and z.
thanks again.
The only problem I see is the gcode is on a hardrive in the makino. It takes an m198 to call it up. Not sure yet if the variables pass to the harddrive.
Hopefully today I can get some machine time for debug.

I just showed you how to do exactly that.
There's this thing called a text editor.
You're welcome.
I'm not using variables.

I have a repeating job that is programmed like what you want. 4 vises on the table. 10 tools used.
T1 G54 (vise 1) G0 X Y Z do work G0 Z(clear) G55 (vise 2) G0 X Y Z do work G0 Z(clear) G56 (vise 3) G0 X Y Z do work G0 Z(clear) G57 (vise 4) G0 X Y Z do work Z (clear) Go to toolchange T2 G54 Blah Blah Blah

Nice. But not exactly what Im looking for. I got the positions, everyone is zooming in on the multiple fixturing positions. The thing im trying to do is take a short generic main program in memory, and have it get tool 1 from a gcode program on the hardrive and run that tools code thru 8 positions....then, get tool 2 from the gcode program on the hardrive and run it thru all 8 positions, etc... untill its ran all the tools on the gcode program on the hardrive. This needs to be done without any editing, cutting or pasting. The program on the hardrive is posted out of the cam system by programmers, and the mill operators never see that code. All they do is edit a tiny main proggy in the memory. Your program works fine if the operator edits the gcode. Something im trying to avoid. Seriously, thanks for the reply.

Why would I buy ncplot? It only does simple macros and has no m198. Its useless. Now you would know this if you used it as opposed to memorizing the guys name who made it.
You jb are a POZER.

If this is a one off, probably yes, but I have the impression that "the boss" wants to minimize tool change time on all the programs, so Vinny is looking for a template to "automate" without having to manually edit every program.
Is there any way to revise the post so Vinny doesn't have to manually do this in the future?
Would a stand-alone program that would parse the gcode program, and then write/sort the blocks into separate files by tool no, then recombine the blocks in sequence be helpful? There would still be some manual editing required.

Yep. exactly. 1 electrode typically has 8 tools average, times 8 positions.64 tool changes. Thats for a 3 hour run. they run 20 hrs a day 7 days a week, 3 machines. The wear alone is a major factor. But, the other benefit is quality. The machine runs 8 tools thru an electrode, from 2000rpm to 35000 rpm, then does the next part etc... You cant hold a tenth or two in a situation like that. So this will get tool 1, and warm up the spindle for seconds relative to rpm, The LASER probe the tool for depth and size, then run at that speed thru all 8 parts.
Im down to testing time. its hard when you dont run the machines you need to test in. All im doing here is cutting down on debug time. Well trying anyway.
Last thing to add is the laser probe code, but i need to look at the toolpickup program to steal the line of code that does it.
Sure. The post processors are written in tcl, you could do anything. I thought about that at first, it would be simple to hardcode an index or loop at the begining of the post processor to do this. But then I thought the operator still has to tell how many positions, and what tool he wants to start on etc...and the gcode is too large to fit in memory, so nobody wants them editing that, even to change a few variable prompts at the top. So they are staying with the easy to edit main program in ram at this point.
You could do it in the cam system, simply actually. The post needs set up for sub programs, and they look like they are visually. You get done cutting, and make the 8 copies of your cut. Not the toolpath, just a symbolic reference....done. Now the program posts out sub calls to the interior of the program and does the 8 positions however you defined them, in variables or in offsets. But....the operator might want to cut less or more positions, start and end on different tools, etc... again, loss of flexability.
SO far...a tiny macro calling up the gcode from the programmers seems the easiest, fastest and most flexible.
The main benefits are the programmers are not involved, and the mill guys keep doing things the way they always have, with a few new options. And I get some damn trodes I can use!

I don't think you can append a variable to a numeric value, as you've done with the G54.
I'm no expert (and I'm a turner, not a miller), but here's a stab at it:
------------------------------------------------ % O0010 (MAIN PROG) #27 = 20 (ENTER PROGRAM NUMBER FROM SETUP SHEET) #28 = 8 (ENTER NUMBER OF POSITIONS 1-8) #100 = 1 (ENTER STARTING BLOCK FROM SETUP SHEET) #30 = 10 (ENTER ENDING BLOCK FROM SETUP SHEET)
IF [#28 LT 1] GOTO 50 IF [#28 GT 8] GOTO 50 WHILE [#100 LE #30] DO 1 (BLOCK/TOOL LOOP) #31 = 1 WHILE [#31 LE #28] DO 2 (POSITION LOOP) G00 G[54 + #31 / 10] X0. Y0. M198 P#27 #31 = #31 + 1 END 2 G91 G28 Z0. M20 #100 = #100 + 1 END 1 M30
N50 #3100 = 2 (INVALID NUMBER OF POSITIONS) % ================================================ % O0020 (CALLED PROG) GOTO #100
N1 T1 M99 N2 T2 M99 (...) N10 T10 M99 % ------------------------------------------------
Can think of a few variations on the same theme, but the above code should be enough to get you started at least.

Pretty well describes the overwhelming majority of my work, except my cycle times are on the order of a few minutes instead of several hours.
Which is to say I'd that I'd have gone broke a long time ago had I not figured out how to machine multiple workpieces before changing to the next tool, which is the strategy you appear to still be struggling with here.

Yet, it works...(unlike yours)
Have fun finding a new job...

Considering the parameters of the project was to not cut and paste for an hour, no...yours did not work. Hell, why not just cut and paste the main and not even have a sub if your going to cut and paste your ass off every single friggen run you make? I dont understand why any machinist, no matter how little skilled would opt for wasting time over making time?
? Now you sound exactly like jb. Next you will call me a pot head or a drunk.
The one Im at does drug tests? Your point? Am I going to be called a drunk in your next reply? How about pointing out I cant spell a word? (predictable)
You actually try harder than jb to deflect attention off your skills. You get an A for effort.
The real problem is at your age if you havnt learned how to be productive by now, you never will.
There...cut and paste that gcode boi.

Write the main program once and from then on all you need is to provide a sub containing each tool's toolpath.

Re-reading this, I notice that I've made a few forehead-slapping mistakes. I moved the G28 block to the main program to avoid an extra program call, and probably put it in the wrong place - should go after the "END 1" block (?). Also mistakenly pasted the M20 at the same time. #3100 should be #3000 (you caught that one).
That still won't work. You're trying to do it all in a single loop - if there's more than 8 tools, #101 will decrement to 0, and on to negative values. You'll be calling G54.0, G53.9, ....
Glad to help, but don't count your chickens before the fat lady sings :)

cut and pasting?

I still never got debug time on the machine, so I passed the proggy on to the head of cnc, and explained without debug time, I cant go any further. So he said, lets look at it together, kinda half debug it. So while showing him the code, I noticed it will never loop. So I went back to yours, seen your double while loops, and now I got the logic working. Fixed a few syntax errors. Then I learned the offsets were G54.1 P1 G54.1 P2. That simplified things. So after some rework, and stealing your loop code, we think it will work. Who knows when it will get tested on the mills, but the guy is adapting it to all his fanucs.
So...THANK YOU wrecker. I learned a lot, and I remembered no matter how small and simple the macro is, the stuff is hard to follow the logic. So I went back to commenting the program, made a big difference.
AGAIN..THANKS WRECKER! This was a fun little project.
Here's the finished product:

Again, not tested, but its as far as it can go without running in the machine. Wrecker, if you want your name on the hardcopies of these programs, email me at with your real name. I dont use that email, so you'd have to let me know i got mail there. They have 20 fanucs, all different brands, and they are putting it on all of em. Its the third largest mold shop in Florida...who knows, you might come work down here some day. They got lots of lathes. Two of em are 4 axis. Lathe guys get the most overtime!
Thanks again man!
Now I need a new project! That was cool.
