Hi All,

I was wondering how many of you that have it, use the CAS on your machines?

There was a lot of hype around it while we were looking at the multus (which we did eventually buy). Our tooling suppliers told us that they had models of all their tools, so it would be very simple to load these into the machine.
We've had the Multus now for nearly a month (and tooling) but have not received said files, which is annoying.
I personally feel that CAS is a gimmick, and this was reinforced when one of the Okuma reps mentioned while installing, that it would not stop the turret from a crash while positioning thru it's 180 deg range.

Hearing this, I feel the time spent building up the chuck jaws, part, and tooling, could be left out of my set-up times. I'm not perfect at all. I make mistakes in my programmes all the time, but I find them while proving out the job, and haven't crashed a machine in over ten years.

So..., do you guys use it?
Will it stop the turret before hitting anything?
Will I sleep better knowing the afternoon shift can't hurt it, if left to finish a set-up?

Thanks for listening.
Dave.
ps. here's a link to a video of our first job done on the Multus!

Hi,

Firstly Good choice on the Machine, we love our B400W

With regards to the CAS our application engineer switched it off when he installed the Machine & stated it was very time consuming to put all the relevant info in!!!

I have had a play with it but I have never switched it on & I probably won't, we do a lot of prototyping on it & it's just something else to add to the lengthy set up time!!!

With the tool models Sandvik have links on their website, we used them for drawing the tools up in Mastercam

Hi Jason,

We too, will be doing prototype work and small batch runs, mostly.
We dont want to spend too much time setting up, and I think preparing the CAS will be a big part of the set-up time.
If long production runs are the norm, then I still dont see any need for it. Whats going to happen?

It's a catch 22.

When I install the lathe, I start training with security items first. My students know chuck and tailstock barrier before they start to cut soft jaws.
There are 4 ... 6 Multus of MacTurn machines at Okuma headquarters in Krefeld constantly for repair after collision. If in case, it means instant bankrupcy to our small customers.
Do You catch my idea? If some machine seller engineer says, that You don't need japanese designed safety system, he probably wants to earn some extra on repair after collission. Or colission. Or colisionn, sorry for my English :-)
It very simple, however. I can't imagine working without CAS.

Dave,

You are totally incorrect here, CAS will check B axis turret movement through the full range of 210° If you spent the 10 mins to set it up it can and will save you many hours of potentailly lost production


So..., do you guys use it? --------------------- Yes you bet

Will it stop the turret before hitting anything? ---------------- Absolutley it will

Hi guyz, thanks for your responses.

I've decided to spend the time and get into using the CAS. I don't feel I could explain to the boss why his new m/c has been crashed, when it has the capacity to prevent it.
I have to say that Okuma have done their best to make a control that is not user friendly. Nothing in it is intuitive, and there is a lack of continuity in it's processes.
The .stp files that Sandvik offer on their website are not compatable. They need to be converted to .stl files, and then modified still further to make them usable. I spent all day today with our Okuma rep (G'day mate) trying to get six tools and chuck/jaws/billet setup. He was still going when I left for home.

Our machine has spent the last week being stripped and rebuilt (twice) to re-align the turret.

CAS would not have prevented this.

If a swarf ring that is left from boring a thru hole happens to jam itself into the GAP between the jaws and the tool tip, then that's bad luck. This has happened to me before (on conventional turret m/c's) with no greater damage than a busted insert and or, shim.
So that's what happened on our multus, and it's a HUGE DRAMA! We went back thru the MACMAN and found no overloads, no E/stops, nothing to suggest anything drastic has occured. No damage to jaws, or part. The tool has a mark under the corner of the shim which looks just like what it is, the result of a tip and shim breaking, which is what the operator said happened.
I cant say for sure what really did happen because I wasn't there.

I know I'm having a rant here. It's getting frustrating to still be setting up this machine weeks after it was bolted down. We haven't even started on the bar feeder yet!

hello!
I don´t use cas because it will take far to long time too program it. I change projects and work material from 6mm too 350mm in diameter or bigger, and everything between almost daily.

hy i did not wanted to start a new thread about this; i consider that this one covers important aspects

one way or another is good to have CAS, thus to avoid whatever + optimizations like disabling it during specific codes, thus reducing overload

also machines worked fine until CAS appeared, thus CAS in not a must

an iresponsible programer thinking of bunnies and an novice operator is a problem

thus is not the CAS, but the fact that training and technical schools diminueshed, leaving the market without qualified personel

CAS is here now to protect the machine against unqualified personel

CAS is ok ... setting up the CAS is worst than "removing USB safely" ; is a waste of life

[deadlykitten]

if i could, i would use a 3d real time handy scanner, so to declare CAS in no time; is almost 2017

simple as it appears, implementing it into actual OSP costs

of course, simple and fast is never cheap kindly !

I had big crash on a multus this spring we were not trained on the cas then now we are and it is well worth it. I did about 60.000 damage at that time you can same all of the programs to a setup in cas so you do not have to redo it set on cas each time just call it up like a program i wished i was trained on it when we got the machine the crash happed when I changed a insert T1000 M603 and then i did not hit rest and started the programm boss just came over to talk to me slam. well I learned to put M602 or M603 in my TL= line too to help me not do this ever again
