Help with Okuma flat turning

[rick kroeze]

Have been trying unsuccessfully on an OSP5020.

Anybody actually have experience with this?

[rick kroeze]

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)

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.

[RODMAN]

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?
