Have been trying unsuccessfully on an OSP5020.

Anybody actually have experience with this?

No one?

Have tried to get tech support from Okuma. They say they've never done it and sort of good luck with that.

Phx,

Do you have the M version... live tooling with the option to do flat turning turned on? (M220-M226)

hi
i have the 5020 without M, and i dont know what the englisch word Flat turning stays for.
i have a OSP 7000 with M.

Might be the same on the OSp7000. If you try a M221 do you get an alarm? If so it doesn't have the flat turning option

Flat turning is a fast process of putting a polygon on a part. It is much faster than doing a X-C contouring operation, although not as accurate. Sometimes it's called poly turning.

If you wanted a part with a hexagon you do approximately as follows:

G50S3000
M5
M222
M3S500
G0X500Z10
Z-5
G1X200F1
X500
G0Z10
M5
M220
M2

Using a 3 flute cutter this should produce a hexagon on the part. The whole program works with no error codes but does not produce the flats. All it does is put 6 equal spaced marks in the part.

See if this helps any (see attached)... Also, make sure you have the tool type defined correctly.

Good Luck,

JR Walcott,

Thanks for the attempt.

Already have those pages. Using that format it doesn't seem to generate the flats. That's the problem. The spindle sync happens but that's it. Some other puzzle piece is required.

I think you are hobbing instead of flat turning. Try turning the work spindle the other direction.

Reversing the work spindle also automatically reverses the M-tool spindle. That would require using left hand tooling. That said I don't see any difference. It still seems to be, as you say, more of a hobbing operation. No motion (change in phase of the two spindles) seems to be happening.

Please describe your cutter, diameter and shape, also part diameter.

Rodman,

Had attempted with 1" dia stock, putting a .875 hex on it. Using a .75 3 flute cutter.

It was just a test so can change anything.

Have you done this before?

That explaines it. Try using a bigger cutter, at least 3''. The cutting action will come from the difference in circumferences and surface speeds. See a demo here, click on product video. Flat turning=Polygon turning=Profilating, basically the same process.

See a demo where?

Also, do the cutting teeth have to be oriented in the holder in the M spindle?

Rick,

Okuma's Customer Support standards are extremely high. If your local dealer can't help you, try emailing Okuma for support (answerman@okuma.com). As an ex Okuma user, service tech. & salesman I'm confident that the level of support you will find, will meet if not exceed your expectations.

Good Luck,

Sorry I missed this post. I have done it many times. You will be needing a larger cutter diameter to make it work better. the smaller the cutter it is to the desired diameter, the more of an arc will be generated.

Hope you got it working...sorry I missed the party...did it clear back in the 80's!

Best regards,

PS> who did you get your polygon head from?

i am sure you reached this one by a link somewhere ... i hope you are not digging :) otherwise, it means that you are bored :)

come on, this thread is way too easy for you :)

Yes, I stumbled on it looking for polygon head info and it made me smile as I took a trip down memory lane. Anybody have any sources for polygon heads? I've got another job that needs them, but they seem to be hard to come by...thus my search :)

I can get lots of cutters through PH Horn, but the head (body) is more difficult. They were typically built with much heavier bearings and mass than a standard live tool.

Thanks for the flaming Superman...I probably deserved it! I guess I should have just started another post rather than hijack this one...but hey...It's a dead one anyway - except for he's maybe got a polygon head and knows the source, right?

Best regards,

PS> Superman, did you move from krypton to be closer to kittens? :) :) :) :) :) :)

Flat turning, polygon turning, Polygon milling, potatoe, potatho. It's for a customer... and you don't OWN me...I think you meant OWE, right? Kindly! :)

i am sorry, i was tired ... i think the difference between 'owe' and 'own' can be tolerated :) just kidding :)

and what is a polygon head ? and it comes with bearings ? please, can you show me such a tool ? i really don't know :)

Does someone know why on my LR15M OSP5020L when I run M221 command spindle and M-tool does not rotate in same direction ?? I need same direction for flat turning

The newer machines all have a parameter that can be switched so that the M-spindle rotation can be corrected. On your 5020 control I do not think it existed at that time. Double check the parameters for a M-spindle setting page.If that doesn't work, try to control by the M13/M14 commands with the M221.

Best regards,
