does calling G55 cancel previous G92?

[Thad]

I'm not much of a Fanuc guy, but doesn't G55 funtion "within" G92? Actually, I've always seen either a G92 OR G54-59, not both. But then again, see the first part of my first sentence. So, my inexperienced answer would be no, it doesn't cancel the previous G92.

I have never actually tried this but it Sounds like an excellent way to crash the machine! Why would you want to use G92 with a new contoller?

 

I last used G92 on a 6M.

 

I think thad has it correct the values would acummulate.

[Tim Johnson]

Calling a G55 should cancel a G92, but I would have the control in single cycle while trying. What are you trying to accomplish with G92?

[fboike]

That depends on if your programming in abs or inc. in abs it becomes zero, in inc its added to it. so yes and no. it depends on the program.

hope this helps.

fboike,

 

Where are you at in Livonia? I live in Westland and work in Canton.

G55 will be a shift from G92. On multi head machines we define the part orgin with G92 then we use G54,G55,.. for head offsets. There are 50 different ways to do this. You can even have a 3rd G52 offset.

Thad,

Major Gauge, Farmington and Schoolcraft.

been hear about 4 years. lots of powdered metal stuff.

[George_Gerhard]

G55 will work from wherever G92 was defined. It is not a good idea or practice to combine the two. G92 is a hangover from older controls, it is not needed on Fanuc controls at all. I never teach it to anyone. Of course you can argue this but after 18 years of teaching customers on multi head machines, I have never had a customer have an accident.

George, that's a great record. 0 accidents. I wish I could say the same. I have wrecked, crashed, and caught on fire several machines. But I run the heck out of them. When people come into my place they can not believe the volume of production we are putting through these machines. The only way I could prevent anything from going wrong is to unplug/unhook and enclose the machine in a glass case.

[Longbow]

fboike, Thad ... you guys both down here in Georgia? Im here in Commerce on I-85 near all the outlet malls. Good to see some home folks here.

[medaq]

Maybe he has lots of positions but only g54-g59 to work with.

 

If that is the case. I use g10 to shove my work offsets in, and call up g54 again.

 

Since alot of my work is fixtured production. I can setup a fixture 2 years ago. Load it back up and be within .001 location from 2 years past. But being production we try and keep our setup down to a minimal, by saving our old offsets in the program.

 

So what I do, since we do not have g54.1 on our enshu.

 

I write in the programs

 

G90

G10L2P1X0Y0Z0

 

Or what ever you want g54 to be. If you want g55 just change p1 to p2, and so on for g56,57,58,59

Anyone have a proven post for a Cinci VCNC750 w/ FANUC 21iMB w/o 4th axis, that they would be willing to share?

These guys will help you alter your post, but

their not giving them away.

Have you contacted your dealer???

 

40+ posts, put your flame suit on.

 

 

PEACE

[GreggT]

I have and I do understand what happens here, I also know that posts are frequently emailed to contributing members from other contributing members. I may not have reached the point of contributing member yet, but it never hurts to ask.

 

I have contacted my dealer, he is Elk Hunting and won't be back until next week. I would really like a clean post now, but I'll wait if I have too. I have a post that is semi working now but requires clean-up to make the machine work properly.

 

Life is hard......

[GreggT]

Oh ya, bring on the flaming. I wear asbestus undis so it really don't matter one way or another.

[Hardmill]

How about starting with what you need to

change on the post you got.

These guys are great about helping with posts.

I did all my own posts but I'm more of a chop

and hack type of post guy.

Give the boys some specifics and see how quick

they solve your problem.

 

PEACE

[GreggT]

Just talked to the actual MC guru and he's saying he has it nailed? I'm more of the design the machine, hand off to MC guru, and then go load stock after he sets up the machine guy. I still haven't got MC learned, kinda waiting for X to show so I don't have to learn it twice. Dealer's saying soon and that it won't even look like 9.1.

 

I should have said:

 

How about a trade. First guy to send me an awesome post with mailing address gets a 12 pack of his/her beer of choice.

 

I am much more relaxed now that I have a Negra Modelo in my hand and the boss has left for the day. Now to get these parts ran.....

 

Thanks Hardmill.

[Hardmill]

I have three 16i-mb controls.

Show me what you code is suppose to look

like (if its even different).

Hi,

What needs tweaking on your post?

 

Don S

[GreggT]

Guess I don't know exactly.

 

We're getting a 3039 THD Alignment Check alarm and a 233 BP/S Alarm right now. Not sure if it's the post or the machine. It's a new install today and the people who placed the machine weren't real help full?

[Don S at Barefoot CNC South]

What post are you using?

Gregg,

I sent you an email.
