randomized tool changer ( sr-40 mill)

[+/-?]

hey guys......new to okuma mills and had a wierd thing happen.....the tool changer went random. i was at tool 19 in the spindle ( always a drill chuck) loaded tools in through the side when i called up T1 via mdi (T1M6) to start gaging tools and the machine put T19 in T14 slot and gave me T7 instead of T1??
im pretty new to okumas ( 8yr. Haas guy) ..........what could have happened? no one at my shop knows why this happened but insists that it only happens when "new guys" are on it. (go figure)

Thanks in advance- Joey

Okuma does not return the tool into the same pot # as the tool

For example
if you place a tool you want as T1 into Pot#1, which actually contains T15,
but Pot#3 actually contained the T1, and you MDI <T1>, the tool in Pot#3 is what is brought into the machine.
the tool that is returned to the caurosel is put into the closest empty pot

When loading tools, always compare the Tool # to Pot # on the "Tool Set" page before loading

When you say you put the tool into the side, did you mean you put T1 into the pot labeled 1?
If so, you have done it wrong. Tool numbers and ATC Pot numbers are different things. Usually, you load tools into the spindle. If loading tools into the ATC directly, you need to look at the Pot and tool number correlation in ATC page of machine.

edit: damn it, too slow a typist, superman beat me. But yea, what he said

Sure, this happens only with newbies.
Okuma never mix tool numbers, but pots. It's very good habbit to set tool through manual spindle tool set - exactly as is described in manual. You don't care, where Okuma places the tool, You care about offsets, description and tool number :-)
Okuma (depends on control how to access it) has tool list, which is usefull to have for programming, to save together with part program and so on.
good luck

Sorry, cricket
Yeh, it's a b*tch when this happens, all the thinking, spell check, proof read, accept as OK. and more often than not it ends in....the WC

Yes typing lessons are a must for this day and age. But if your machine has that a Fanuc compact keyboard then typing lessons won't help much

right.....but why 99% of the time when i load tools in through the side door in the pockets i want ( t1 in pocket 1 etc.) and leave the turret in what ever postion its in after loading all tools, the machine will still give me t1 when called up with mdi ........this time it didn't? just wondering what caused it so ill know what to look for.

i personally like loading tools in through the spindle but the brass does not.

If the magazine is completely emptied after each run, there does exist a method to reset the T#'s back to pot# ( I've used it a long time ago )

(someone may post that method )

If not all tools are removed,
the easiest method is to write down what tools are in what pot, then load them into the magazine, and then update tool lengths and comps ( MDI in the tool, verify the correct was loaded, set comps and tool measure )

What Steve said is true that is the fastest way, if you are required to load your tools into the side of the machine. If I were you I would explain to the "brass" that it is very time consuming and leaves alot of room for human error (not that I suffer from that, but I am just looking out for the people)

What is happening here I think is the machine is new , so the pot numbers are corresponding to the tool numbers, so unless every time you do a setup you remove all tools from the previous setup, and load the new ones in sequence the spindle starts to put tools back in different pots. But this will not effect anything if you use MDI and load the tools into the spindle. Because the machine keeps track of which tool is in which pot.

what caused it so ill know what to look for
must be some error message, pointing to reason.
Push the button :-)
there is tool management mode on this control, and you can see exactly what tools are set and which pot they are sitting in.
if the pot is empty in deed, but it is described in OSP as is contains some tool, the alarm occurs depending on parameter setting.
