Okuma PPC help

[Caprirs]

I just started a new job with a company that has thrown me on an Okuma HMC with OSP-200 control and a pallet pool. The guy who ran it previously isn't available.

Oddly, I figured out the PPC schedule of pallets after a day of reading the manuals and pressing the buttons. Scheduling pallets into the pool for automated sequential operations is well understood now.

My problem is the simple part. How do I call a pallet into the machine without scheduling the pallet into the pool and registering a program with the pallet? For example, during set up, I just want to use MDI (or a simple program) to bring pallet #3 out of the pool and into the machine. I have found references in the manuals for:

- M101-M112 for pallets #1-#12
- M60 and M160 to run the APC
- NP command which indicated a Next Pallet command

No where in the manuals did I find examples of how to use the above codes. I tried putting just M112 into MDI but nothing happened. Is there a format for getting a specific pallet into the machine without going through the schedule/register process?

Thanks for any help for this noob.

I have no idea about your Okuma but logic would suggest to put both commands in the program......

M112 (set pallet 12)
M60 (run APC which will get pallet 12 and bring it into position)

possibly?

kind of like doing a tool select first then the tool change.
T12
M6

Thanks for the reply. I did try that exact sequence in a little dummy program. I also tried putting just the M112 into MDI. Hit cycle start and the machine just sat there like it was waiting for something. No alarms and the green/yellow blinky indicator in the upper left corner of the screen flashes as if the program is running correctly. Unfortunately, nothing happens. I know I'm doing something wrong or missing something simple.

I feel like a moron. Standing at the PPC subpanel, I can carry out each pallet to the set up station and then carry in each pallet loading them into the PPC schedule. With the PPC mode switch on (one cycle or continuous), hitting the PPC cycle start on the PPC subpanel will cause the machine to run each pallet in the assigned order.

It seems there is a way of bypassing the PPC schedule and just calling specific pallets into the machine but it eludes me.

NP and M60 in MDI mode shouşd be ok. PPC may be OFF positon.

Thanks for the help. I figured it out. Format should be:

NP=1 (or whatever pallet #)
M60
M02

PPC mode switch should be off.

Not sure what the M101-M112 codes do yet though but they are not for manually calling a pallet into the machine. I'm learning slowly.

We use a macro g119. Inside the library file, palet.lib, is the info to pull out the pallet. Eg
Np=pp
M334
M160
Rts

The m334 talks to the ppc.
To call it in mdi, G119P# (pallet no.)
Use what works for you.
Using macros is a good way to condense you commonly used proceedures. We use them for helical milling, dynamic datum shift, probing cycles, tool setting etc.
