Category : Fanuc Fanuc Parameters

Messing With Parameters Can Be Fatal!!!!!

Unlock Programs Fanuc Parameter, first of all you’ll need to go to the setting screen and change the parameter write box to a 1.

Cutting Feed-Rate 0% No Movement

When you set you feed-rate override to 0% the machine will not move. Some operators like to use this when proving out a program

All you need to do is make Bit 4 of parameter 1401 into a 1 and the machine will not move even in rapid.

Bits n Bobs

When counting the bits in parameters you count from right to left so the first one on the right is bit 0 or sometimes known as #0

Parameters You may Need to Change

 

1300 Stops over travel alarm

1401 Cutting Feed-Rate 0% stops movement of machine

3101 Clear Screen

3203 Clear MDI Screen

3204 Unlock Program 9000 to 9999 and 8000 to 8999 to Edit

3291 Wear Offset requires Key to Adjust

3401 Calculator Type Decimal Point or Integer

3402 G Codes that are Active When The machine is Turned On

5003 Retain Geometry when you Press Reset

6005 Allows the Use of Local Subroutines (Newer Control)

6050-6059  Allows you to Call a 9000 series Program with a G Code

6080-6089 Allows you to Call a 9000 series Program with An M Code

8134 3453 allows you to use ,R and ,C (Rads and Chamfers)

That’s it away you go.

Oh just one other thing before you go off and cripple your machine forever.

Do yourself a favour take a picture of the screen before you change a parameter. If you aint got a camera then you must have a piece of paper.

Even better back everything up.

Thanks

G92 Threading Single Line Method

Tags :

Category : Fanuc Fanuc Turn Haas Turn Mazak Turn

G92 threading Cycle is something that concerns me. It’s sadly neglected. Now I know you’re probably saying “no one uses that old shit anymore”

Well you could be wrong.

G92 Threading works exactly the same as G76 except you need to programme every pass. This would be a pain in the arse but hear me out.

The Haas G76 cycle does not have any facility for a spring pass. This is where you add extra cuts at the end of a threading cycle to take out any metal left from the tool pushing off.

On a Fanuc control you can put these extra spring passes in as part of the G76 cycle.

Read this if you need to know more.

If you want this on your Haas control or an old Fanuc control then you can do this.

G76 X16.93 Z-25. K1.534 D.485 F2.5

G92 X16.93 Z-25.
X16.93
X16.93

Just add the G92 after your G76 cycle and whatever X figure you want to go to.

The G92 is modal so you will need a G0 move to cancel it. The code above would give you three spring passes.

Here is a load more interesting stuff.

I hope you have enjoyed reading this article.

Fanuc Editing Copy and Paste

Category : Beginners Fanuc New Stuff

Fanuc Editing Oi Model D. This does vary on the age of your control this article is for a newer control (Fanuc Oi Model D).

Read this article if you want to see Fanuc Editing 18i (older control) or this one for older Oi control  copy and paste.

Now I’ll warn you that it’s not a simple process but if you get into the habit of using it you’ll never leave home without it.

I am definitely not going to rant on and on about why all these simple procedures were not introduced years and years ago. Why has the editing on CNC controls generally been so shit over the years?

I am also not going to rant and and whinge about how fuckin complicated it all is.

I mean bloody hell all I want is to take this shit here and join it to the end of this shit here.

I’m not asking  for an “X Factor Audition Here” (Simon if you are reading this my contact details are above) I only write this crap to try and make some money, my really passion is singing and exotic dancing in my underwear. I really want this Simon, just one chance is all I need.

Ten Things You Might Not Know About The Fanuc Sub Program

Category : Beginners Fanuc Fanuc Mill Fanuc Turn New Stuff

Sub Program Fanuc

Here are ten things you might not know about Fanuc sub programs,

Fanuc CNC controls are the most common controls in the world so it might be useful to have a good understanding of how sub programs are called and used.

(1) You Can Call a Sub Program By Name.

Yes you heard it here the program can be called by it’s name or it’s number. When calling by name don’t use the P.

Just put the name of the program in these things <> with an M98 and your away.

M98<ALBERT>

The only problem with this is that the syntax needs to be spot on so if you have got complicated names for your your sub routines then you might be in the shit.

I always call mine names like ALBERT that are easy to remember.

(2) You can use internal sub routines on a Fanuc Control.

Some people call these local sub programs. It just means it’s tagged on the end of your program which makes them nice n easy to look after. A bit like a pet Goldfish or a pet fly.

I bought mine from the local pet store. I asked the assistant if he sold pet flies and he said no. I said “well there are loads in the window”.

Anyway he sold me one (£15) his name is Paul

 

This is not him this is Steve.

Internal Sub-Routines

By typing M98 Q500 your control will look for N500 within your current program. This is great because you can add the sub programs to the end of your main program. Don’t forget to leave big gaps so you can clearly see where and what they are. Oh and mind your P’s and Q’s.

M98 P500 (Call O500 externally)

M98Q500 (Call N500 in main program.

Oh and read this too.

Sub Program

Just one other thing. Watch your n numbers it’s easy to get them mixed up. Try and use a convention.

I Just Love Old Machines

I recently got to train someone on one of these, a Webster & Bennett with Fanuc 10t Control.

Webster & Bennett

It’s what I crudely call a big bastard. But bastard it is not, it can definitely machine some big shit

Webster & Bennett

Like this monster.

Don’t ask me what it is or I would have to kill you. Joking aside I think it’s a water valve. Beware these jacuzzis use a lot of water,

The machine is a Webster & Bennett vertical borer and I think the Fanuc 10t control was possibly a retro fit.

When these start whizzing around even a few RPM it can scare the living shit out of even the most seasoned engineer. And me, well I,m more seasoned than a piece of Nando’s chicken.

G50 on a Webster & Bennett Your Best Friend

Anyway joking aside your best buddy now is definitely G50 get this wrong and it’s fuckin world war three.

Imagine the scenario, you program G96 S180 M3. Spin at 180m/min. Not too fast but…. what if the tool is sat in the middle of the part.

Machine says “come on lads happy days foot to the floor flat out joy riding” and it fucks off like two teenage boys in a stolen Lamborghini.

So without a G50, or the wrong speed, this beast will accelerate to it’s maximum rpm.

Oh and did I Mention it’s harder to stop than a P & O Criuise Ship with 4000 obese pensioners on board?
