Okuma memory

[billm01830]

I have an Okuma Cadet that has a very small memory for part programming. I believe there is another section of memory that is much larger but I don't know how to acess it. Can any body help with this.?

[Algirdas]

what is "small" in your opinion?
can you write manually 4kB text?
How many lines (blocks) your part program contains?

[billm01830]

I make programs in MasterCam X5 some contain surfacing and the Okuma will only hold a very small program of this type. I also have proplems with multipul parts even if I use Sub programs. I have to go to a newer machine for these programs. Nothing else I can do.

Thanks

You can add DNC-B (Drip Feed) or DNC-DT (HDD)

BB1: and BB0: are the commands for the different memory.

some contain surfacing
now I understand, why you need more memory
You can add DNC-B (Drip Feed) or DNC-DT (HDD)
it is only solution if.
If your machine is suitable for required work. What maximum rpm is?

[billm01830]

MAX RPM IS 8000 DO YOU HAVE AN IDEA OF THE COST TO UP GRADE TO THE DRIP FEED?

[underthetire]

~5K

MAX RPM IS 8000
how can you imagine to make 3D surfaces with that spindle speed?
This machine is not worth such a retrofit. Cost is high, because the control is not designed for that. It is possible, that from software side there is no possibility just to add a feature, software must be re-compilated at that case ...

play with the filter settings in mastercam , you will be able to reduce the code length
or you can use the split NCI C-hook to split the G-code to a certain file seize (it's 32KB max on the cadet and OSP5000M control)

okuma says they dont offer the DNC-B option anymore for okuma cadet 4020's. the other solution i found was predator dnc as a post processor. the salesman there was telling me that they configure the software to break up the long programs into useable sections all for you. BUT, you have to send and recieve the programs with your own fingers. But at least it breaks the program into custom sections for you.
