Okuma LB15 with OSP5000L-G control with IGF

I finally got in a manual a few days ago (thanks metalmuncher!) that goes into great detail pretty much about everything, however, no where can I find where you enter in a program at the control other than putting in info via MDI.

Do I just MDI the program in and then save it some how to memory? Well yeah, duh.....but I can't for the life of me see where to save it into the memory.

The machine has an RS232 but there is not one mention of it in the manual or how to access it or download programs into the control.

I just got in some jaws yesterday for the chuck (finally!!....not too sure if I'll use workholding.com again! :angry:) and have the machine all tooled up and ready to make some chips, but the learning curve is STEEP!

Well, at least for me it is anyways. Still kicking myself for not buying a Fanuc machine..........

Heinz, why don't you have any Okuma DVD's!?!?!? :bawling:

Why do I do this to myself!! I hate not knowing what to do or what buttons to push.....and most of all, I hate trying to decipher the manuals to do it!!

Anilam, Yasnac, Fanuc, Haas.......and now Okuma! I think I need my friggin head examined.......:willy_nilly:

If there is anyone local who has experience on this machine or control, I will GLADLY pay you CASH for your time to come in and give me a crash course (probably could have worded that different) on this machine.

Any and all advice on loading a program at the control, either by hand or via the RS232 would be greatly appreciated.

Maybe it's just me.....most likely is.....but this control seems to be sooooo overly complicated, I could just scream!!

Later,
Russ
 
Hey everybody,

Don't help Wrustle till he finishes his story of "My Ikegai has gone off to a better place".

Kidding.

Can't help ya though, I only speak G code and Mazatrol.
 
Been there - I got a Mits in a cpl yrs ago. :willy_nilly:

You may want to take one of these to take the edge off.

I dont have okuma experience but on a Fanuc you have to set up communication parameters between the machine and some type of DNC software (parity,baud rate ect.) I imagine okuma is the same. I use Machine Link software by controllink systems inc. As for MDI, I dont think an MDI program can be saved to memory. I could be wrong. Okuma had thier own conversational type programming called IGF. Is your lathe equipped with this? Dont get fustrated you will figure it out. Try googling Okuma RS 232

Actually Tom, that's a GREAT idea!! :cheers:

I will hold all of you hostage with that story until someone HELPS ME!! :eek:
 
Russ.

If I recall that machine was close by. Factory full of Okuma’s, and the owner was a decent bloke – re the 30 day guarantee.

Give him a call and see if one of his guys wants to pick up a few cash bucks for Saturday. Some one from there must know that machine well.

Cheers Phil.

Great advise.

When I started out on my lathe I had no clue where to start. I called an old coworker who is a lathe ace and he had me going in a couple hours.
 
I have a few years experience with IGF, but it's been a long time ago. I'd almost have to be in front of the control in order to start remembering how to maneuver around again. Once you get it, you'll love it.

I can try to answer specific questions, but I can't guarantee anything. My memory banks aren't what they used to be.

I do remember that, once you made your program in IGF, you then had to turn it into a G-code program. The two sides of the control between IGF, and the G-code side were quite separate from each other.
 
Wrustle,
To key in a program by hand:

Press Edit Aux button on the Machine Mode line.
Press Edit button (F4) under the screen.
Type in program name. (J1234.MIN) Be sure to include the .MIN extension.
Press write button. (Right side of control)
Type in the program. Press the write key after each line.
When finished typing, press Edit Quit (F7). MAKE SURE YOU PRESS EDIT QUIT!!
Press the Auto key on the machine mode line.
Press the Program Select button. (F1)
You should see PS on the screen. Press the * button.
Press the write button.
This will bring up all the programs in the directory including the one you just typed in.
Cursor up or down till the program you want to run is highlighted using the arrow keys.
Press the write key.

I know this sounds like a lot, but once youv'e done it a couple of times it'll be second nature.
As far as Okumas go, I have been working with them since 1982 and don't think there is a better machine out there. Once you start running yours, I'm sure you will agree.
I have included a sample program for your reference.
Any more questions? Ask away.

Rick

It shouldn't be this difficult. I can try help you out with what i can remember. I'm not infront of the machine right now.

So if you want to write a new program using One touch IGF.Press:
-New Program
-One touch IGF
-Give it a file name.(It has to start with a letter)
-Define your blank dimensions
-Create your program step by step.
-Make sure everything looks good, (use the verify screen to do a dry run).
-Press "Program Create" to automatically write your program in G-code.
-Also save your IGF file in case you want to make changes.
-When you press Program create, it is automatically saved in the directory MD1.
-Call up your program and you are ready to go.

Let me know if this helps..
 
Hey Rick, I'll give it a try, and let you know how I did! Thanks a bunch!

BTW....how can you have multiple "M" codes in a single line? I thought that was taboo!

Best Regards,
Russ

I literally have close to a hunderd Fanuc programs I need to convert and when needed load into the machine. When I get to the "creating a program" part I will be sure to print out what you have here for a reference. Thanks for your help!

Later,
Russ
 
Wrustle,
With Fanucs you are normally only allowed one M code per line. Not so with Okuma. Use as many as you need per line.

Rick
 
Hey, Rudedude,

I'm judging by the control number he gave, it might not have "one touch" igf. It's probably just IGF, which is probably much easier to learn from the beginning.

Also, there are some controls that allow multiple M codes on the same line. My fadal will do it to.
 
Sorry,Russ, no Okuma DVDs.
I decided a long time ago to really concetrate on Fanuc, but there are lots of Okuma's around and you will get some great help from the guys.
How long ago was it that you started with the Ikegai?
Time really goes by, does it not?
Good luck: Heinz Putz.
 
This is a canned cycle I have for turning a simple OD using a rough and finish tool. If you were to use only one tool add the G87 NTURN line on the line after the G85 line. I am guessing you need the N lines in front of each line for that age of controller. It has been quite awhile since I used or seen IGF, used it with the old 8-1/2" floppy on a simulater and on the machine to, but as mentioned above draw your stock and then explain each segment of the shape you want to turn or bore. Chamfers, radius turns etc. Again has been awhile but would be willing to help out.

All letters must be capitals too. Anything in parrenthese will be skipped also so you can put any notes in the program also.

Hey guys, all great stuff here.......keep it coming! Give me all you got.


Question, How the hell do you tighten the bolts for the jaws without the chuck turning?

My other lathe had a spindle clamp, so it was easy.....flip the switch. I don't see any such animal here. What do you do, besides put something in between the jaws and turn the chuck to wedge it against something to tighten the bolts. :confused:

Later,
Russ
