O/T Subprogram call

[TheePres]

Im running a multiple part program on Fanuc 18i, using subprogram call. This machine needs more memory, so i have to save each individual sub to memory card before loading next batch of programs for secondary operation. Very time consuming.

Is it possible to have sub programs imbedded in main program and call them by block # instead of Prog # ?. I seen this done on Fadal, but find no reference to this function in Fanuc manual.

 

2nd option would be to DNC directly from flash memory card, has anyone done this ?

[crazy^millman]

No not from Flash But look for James response about 2 or 3 months ago he covered this very well. We are thinking of going ot this with 512mb cards.

i have never seen a fanuc control that can do local sub calls. its a bummer

[Tim Johnson]

If you macro it up I THINK you can;

 

N1 ~ N100 BLAH,BLAH BLAH

N101#501=103

N102GOTO12301(GO TO BLOCK 12301)

N103 ~ N12300 BLAH AGAIN

 

N8765M30

 

N12301 ~ 12400 DO WHAT YOU NEED

N12401GOTO#501

 

Note: I've never tried this but it should work.

If you are low on memory space,how would this help?

Curious though,it would be nice to do that on a fanuc like I can on my Okuma.

That way there is only 1 program to load to the stinking machine!.

If you DNC in tape mode you can search for specific

block #'s. I do it all the time w/ our 16i control.

 

PEACE

TheePres, I see that you are runnung an 18i control and I may be off base a little, but I am looking at a 6M operator's manual and it says in here, that if you give an M99 with a "P" code being a block number, it will skip to that block number. With some massaging, you could probably get it to work. If you like I could fax these pages to you.

DNC From PCMCIA Card

[specv]

This is the way we do it...

 

N8T[#701]M6

N9T[#703]/M26

(4.0 DIA 5 FL FACE MILL)

N10G65P9222A4.981

N11G4P1M26

N12G0G55X-2.1438Y-22.1612S5000M3

N13G43H1Z1.

N14#656=1701

N15M98P1191

N16G54X2.156Y4.1773

N17G43H1Z1.

N18#656=2701

 

Then the sub would look like this:

O1191(0188.P01/PAL1/TOOLSUB)

(4.0 DIA 5 FL FACE MILL)

GOTO#656

N1701

N1X-2.1438Y-22.1612

N2Z.1

N3G1Z.01F100.

N6Y2.1612

N7Z.1

N8G0Z10.

N9M99

(4.0 DIA 5 FL FACE MILL)

N2701

N1X2.156Y4.1773

N2Z.1

N3G1Z.01F100.

N6Y-20.1773

N7Z.1

N8G0Z15.

N9M99

N19M98P1191

specv ,

What do the 1701 and the 2701 #'s represent?

[specv]

Well we use macro #'s to call tools, so #701 is tool #1. we needed a way to tell if the tool was used again in the same program or a different operation so the first time the tool is called we write #656=1701, the second time or second operation is called then we write 2701, third is 3701 and so on... then when we get into the sub we then put a goto statement in the top of the sub to go to the particular code we need to run. so if there are multiple parts we just keep the #656 number the same and keep calling the sub

[Craig-B]

I use a method something like Specv, but a little different. You must have custom macro B on your machine for it to work

[TheePres]

Thanks for responses, looking at your macro codes just now, seems like gibberish

 

I'll print ths out, take a look tonite and almost positive I can solve that code.

 

This method will not solve memory issues, was just after keeping all subs under same File in flash card, for ease of operators, as they currently have to transfer files individually from card for each set of parts

 

Now off to read James post on flash cards.

 

Thanks all

[wtsylvester]

yes like robp says... you can M99 P(line number)

 

follow that sub with a M99 and it should return to line after the first call..works on our mori/makinos

 

you say,

but find no reference to this function in Fanuc manual.

Heck the mori manaul has more legal disclaimers than answers
