Macro Variable

Fanuc 16i control.

 

Hey all, does any one know which system variable reports the current tool number that is in the spindle. I am not looking for #4120 but the variable that actualy reports what the current tool number is in the spindle. #4120 reports the current T code that is programmed, but this will not report the "current tool" in the spindle, if a tool pre-select is programmed.

 

[Charlie Pierson]

Try #4111 - H code after the tool change

[Charlie Pierson]

I forgot , this might only apply if you are using "tool life management"

 

Otherwise test for #4120 after tool change but before ant other tool calls like pre-staging

[Jerome]

Thanks, didn't think of that one.

[Jerome]

did that it will work untill a preset is called

[Rick McAllister]

Jerome,

#999

[Jerome]

What! Satans number!

 

I can not use that number, my machine will become possesed, and vomit on the machinist.

 

Is it realy #999?

[Charlie Pierson]

Jerome,

 

May I ask why you need that variable ??

 

Thought satan's # was 666

 

My documentation shows that #999 is the last in a sequence of the additional common variables option

[Jerome]

We use full radius comp here and I wrote a macro to verify the tool radius value input. I check the input value into the dia offset register with the current tool number in the spindle.

WE have common offset types

H and H shared.

Some of the guys input the wrng value in the past and scrapped parts.

instead of .093 they input .93

[Jerome]

That wad H and D sorry

and is not the number 666 universal as 999 also?

that is why 666 is the number of choice for the bad man..............

[Charlie Pierson]

Are you passing an argument w/ the nominal radius comp and comparing it to the actual value ?

 

I did it that way for height offsets after one of our operators cleaned a tombstone right off of its mounting plate

H value -45.678 instead of -4.5678

or, using positive values

.4567 instead of 4.567

 

thought 999 was satan's number for dyslexics(sp?)

I couldn't find any other reference in my fanuc manual. Could you just use a user defined variable set in the M6 tool change sub. Then you could access it at any time and no the tool actually in the spindle.

P.S. I'll keep an eye open as I use the manual, usually I can't find anything when I want/need it. But then in a couple of weeks, it jumps off the page at me.

How about;

 

code:

---

G91G30X0Y0Z0

M06T08(1/4" THREE FLUTE CARBIDE END MILL)

#501=#4120

BLAH

BLAH

BLAH

[Jerome]

We currently use #630 to store the tool number.

But I would still like to get the system variable for the tool number. Mazak has a system variable for the current tool in spindle and it is handy.

Hi Jerome

[mgsanchez]

Maybe this might help. Haas supports Fanuc 10m macros.

 

For a Haas, Variable #3026 (Tool in spindle, read only)
