OSP 200M will only run a toolpath in single block.

[Chris Rizzo]

Program (mill) runs all sorts of dynamic toolpaths no prob, then gets to a simple 2d chamfer and just freezes. What's weird is turn on single block and you can step through the program just fine. Checked all active g & m and nothing is different from a good running program. All moves basic G3's with I J K's.

 

Ideas Okuma guys?

[Greg Williams]

Are any of the Key switchs on/off?,

Handwheel on/off?

Is the door closed correctly?

Is the STM light on?

SIngle block changes the buffer behaviour, have you tried running the file is a different selection method A-B or S MTD/

Does the program work if you copy and past the forst 10-20 blocks into a new file?

 

Can ya post the code if all else fails

[Mr. M]

Put up the code if you can or PM me

[Chris Rizzo]

Thanks fellas! Still no luck.

 

Are any of the Key switchs on/off?,-SET TO PRODUCTION, and tried everything else

Handwheel on/off?- OFF

Is the door closed correctly?- YUP AND LOCKED (WITH LIGHT ON)

Is the STM light on? WHAT'S THE STM LIGHT?

SIngle block changes the buffer behaviour, have you tried running the file is a different selection method A-B or S MTD/ - I'M AN OKUMA ROOKIE, A-B SELECTION BUTTON DOES NOTHING. what's s mtd?

Does the program work if you copy and past the forst 10-20 blocks into a new file?-Still NO GO STILL

 

Hi-Cut is on.

 

It's so weird because the previous tool will run just fine, and not even touching the machine it will tool change, go to the offending op and freeze and only run in single block mode.

 

Here is a program that runs fine;

And the culprit program. Freezes on line 210 and then will only run in single block mode.

Here is what's active, both programs identical active codes.

 

[Greg Williams]

Chris,

 

That sounds frustrating. This is the STM light, The pic is from a lathe but the Mill has the same light. The A-B button on the panel is for something else

 

The differnt run methods A,B and S can be changed when you select the program. The slection is in the top right hand corner

A = Standard method

B = Large Program method

S = No branchs

 

Or something like that as I am going from memry here

[Chris Rizzo]

Thanks Greg,

 

Hmmm our program select window looks different, and I don't recall seeing that choice of program size. It's a 200M on a new Bridgeport/Okuma machine. I'm away from the machine till tomorrow afternoon, but can't wait to get back at it and check. How do you take the screen shots of the control window? Can I plug a keyboard in and hit prnt screen?

 

I turned on the filter in the toolpath, reposted, and it will run fine then. Leads me back to something with the actual code it doesn't like. But you'd think it wouldn't run at all if that was the case....but it WILL one line at a time. The geometry is a gear profile that is arcs and lines. The code you see up there is unfiltered, and still has nice arcs and not point to point.

 

Between this, jamming up the tool changer, and hooking it up to our deep college network I'm learning this machine pretty quickly!

[Greg Williams]

Chris,

 

I use RealVNC to remote to the machine, then a screen grabber. Basically you can use any remote access software, well except windows RDP as it locks the screen.

I have never seen an OSP on a Bridgeport so maybe there are some subtle differences. My hunch is that there is a problem with the code, somewhere down further, turning on the single block changes the program buffer behaviour. I think the error would finally come up after you wore out the cycle start button.

[Mr. M]

Side note, you can just plug in a keyboard and use the print screen function. I will look at this more tomorrow afternoon

[Chris Rizzo]

I think the error would finally come up after you wore out the cycle start button.

 

I almost did that, and my thumb. Just to see it all, I ran all the way through the program in single block....Chamfering a 20 tooth gear, each tooth about 15 lines of code.

 

Here is a link to the machine. A Taiwanese built with all Okuma electronics and drives....and the American name of Bridgeport/Hardinge. Can't imagine how the hell that all came about, but pretty interesting combination of nationalities.. They wanted to compete with Haas/commodity machines I believe. Well put together for an $85k-ish machine. Good sheet metal and design, way better spindle, Okuma control, etc. etc. I like the thing, but the ballscrews are pretty small. It's pretty fast and reasonably accurate. AND a few weird issues with the control. THIS being the latest!

 

Here at the community college I teach at, we have a nice program going with the the Okuma dealer (Gosiger). They needed a presence in Oregon, we needed technology...,.so we started a partnership. We dedicated a nice showroom/shop, and they brought in several machines. Sandvik also stepped up big time and contributed at least $40k of tooling. They bring customers in, we (advanced students and instructors) get to run them, learn and play. . Pretty darn cool.

 

Great relationship. Gosiger get's to demo and sell machines, we provide the trained operator and a student gets a job..... and manufacturing grows back in America

 

(and folks get to see Sandvik tools run at some ludicrous rates....1/8 drill at 85ipm 1" deep x 50 holes)

 

My usual AE is out of town, so I'm fumbling through this on my own with you guys. Thanks again.

 

 

Hell, if I have a problem with my garage door opener, I can usually get a faster (and better) answer here at the mastercam forum that at a garage door forum!

[T_MALENA]

Chris, Sounds like you have some parameter settings out of adjustment. Can you e-mail me the program? I have the same machine here(GX1000 w/OSP200M) and it's sitting idle. I'll load it & run it then we can compare parameters.

[T_MALENA]

Also just ctrl c to copy screen then open wordpad & ctlr v to paste it(using the Okuma control keyboard).

[T_MALENA]

Whats the entire program look like? Dont forget look ahead, you may have a issue with block n555 but freeze on block 200. Look ahead doesn't work the same when in single block. Actually I think single block, high cut on, high cut off all make it perform differently.

 

and you have mail.

[Chris Rizzo]

Thanks T, I'll be going in shorty and get back to you on the mail

[Mr. M]

I ran the part of the program you put up in the GX I have here to make sure I wasn't missing anything, but it ran just fine.

[MotorCityMinion]

Perhaps a little OT here. With beer goggles on, that is one hideous looking screen shot Greg posted. Looks like anti Fanuc / g-gode. Are these guys the "Apple " equivalent of machine tool controllers?

[jeff]

Perhaps a little OT here. With beer goggles on, that is one hideous looking screen shot Greg posted. Looks like anti Fanuc / g-gode. Are these guys the "Apple " equivalent of machine tool controllers?

Looks like IGF code that gets posted at the beginning of the program to define stock shape and other variables.

[Mr. M]

And a macro that is running

[Chris Rizzo]

Thx for all the help guys. Here is the entire code, for anyone who wants to look (or try). T, I'll send it to you offline too. It really sounds like somthing is wrong in the machine parameters.

 

EDIT: the stm light is NOT.

[Greg Williams]

LOL yeah sorry about that. Okuma's run pretty standard Gcode, Basically Okuma code is the same as a FANUC with a few different G and M's here and there.

 

This particular code is basically a MACRO as Mr M said. Here I program the toothpath in mastercam in the front plane. All of the geometry is drawn at Z0. The machine then projects the shape at a depth (V100) on onto a radius (V106) that is on the front of the part. We do lots of different rads, and we want to be able to use the same program for different parts, hence this funky code.

Essentially this is Pythagorean theorem a² = b² +c² or as in this case the radius - (Square root of the (radius² - X position²) and then the same for the Y position. It works a treat

 

Gotta luv the fully editable mastercam posts'

 

G1 X-7.667 Y-13.08 Z=V100-[V106-[sQRT [[V106*V106]-[-7.667*-7.667]]]]-[V106-[sQRT [[V106*V106]-[-13.08*-13.08]]]]

X-7.668 Y-13.28 Z=V100-[V106-[sQRT [[V106*V106]-[-7.668*-7.668]]]]-[V106-[sQRT [[V106*V106]-[-13.28*-13.28]]]]

X-7.668 Y-13.425 Z=V100-[V106-[sQRT [[V106*V106]-[-7.668*-7.668]]]]-[V106-[sQRT [[V106*V106]-[-13.425*-13.425]]]]

 

Back to the issue at hand, As the STM light is not on, this means that the machine is not waiting for a confirmation from something, My hunch is that there is an issue with one of the circles in the program. Does it run with Hi-Cut off? also does it run with a very loose tolerance is Hi-cut, maybe double or triple what you have or 1/2 of what you have?

[T_MALENA]

Ran the program with no issues.

[T_MALENA]

goto your Hi-cut page & check the settings. I compared my screen shots with those already posted & they are pretty much the same. Exactly like the one Chris posted(makes sense they are both GX1000) & similar to Greg's pselect screen - but Gregs looks like a lathe & we have a mill. You're running a normal program with no branch so A-Mtd should be your option(pselect screen). Try looking at Hi-cut settings min feed, min rad, min/max error etc.

[jeff]

E100m control here, your program ran fine.

My HI-Cut options are limited to what you have I believe, so I put my tolerance at .0001" and max feedrate at 1100ipm.

No issues.

What are your Hi-Cut settings at?

[Mr. M]

I think I won't bother running the rest of the code since you all did.

But yeah, post up the high cut settings or you could add them into the program also

 

edit:

High cut sample code

 

G131 F500. J1 E.005 (at the beginning of the cut)

 

G130 (cancel at the end)

[Chris Rizzo]

We got it!!!! (WE meaning you all guys ) Turned Hi-cut off and it ran!

 

Then changed my Hi-Cut from this:

 

 

 

To this, which was your guys' setting:

 

 

 

 

It was the machining tolerance that fixed it actually....

 

All this precipitates a whole bunch of other questions...cause I gotta know.

• The smallest arc on my part was .033".
  
• The smallest arc in the toolpath was .073 ( backplotted and saved geometry).
  
• The value in my hi-cut machining tolerance was .010 which threw it into single block only mode. What's the math that's happening? Okuma apps guys?
  

When this problem started last week in a futile attempt in the header I was putting in G130. The manual says G130/131 will only be functional if Execution mode is set to OFF. I was set to ON, so G130 was doing nothing. Now to start playing with G131 F, E, & J. Do you guys utilize any of this?

 

Beers on me when anyone is in Oregon.

[YoDoug®]

I use the mplmasterOkuma post that has the high speed G131 command in the misc reals. I normally set the control parameters up at around 1500ipm and .0004 tolerance and standard mode. I use the misc real to output G131 F2200 J2 E.01 for dynamic tool paths. Post big loops using mcam filters and watch it zing.
