Polygonal Turning

[ve2lva]

Anybody can tell me if a PUMA 230 with Fanuc 18i can do polygonal turning. Is there any parameter i have to change or it's a Fanuc Option ?

Thank's

I hate to ask but what is "Polygonal Turning"?

[The Puma Man]

The turning of polygons are machining of any shape that has equal sides e.g. squares hexagons etc. Like what was machined on capstan lathes with a cam operated nutbox 30+ years ago

The Puma Man;

Now you will have someone ask what a cam operated nutbox is. Did you operate a capstan with this ability? Herbert possibly?

Theoretically it would be possible to do this on a CNC lathe because the problem is not any more difficult than rigid tapping but I have no idea if it has ever been implemented.

it's in my fanuc manual somewhere. I'll get back

I did use a capstan with this attachment in my apprenticeship, but that was 40 years ago can’t remember the capstan make though.It was used for turning stainless bolts for b.a.c which is now Airbus UK

Polygonal turning is an optional extra on the puma 450 with fanuc 18t so it might be possible on the 230 with fanuc 18i as long as it has a driven toolpost on the turret, i.e.you can drive an endmill in the toolpost. On the 450 it's a matter of having this facility and finding the Polygonal parameter and turning it on.

If you are using live tooling on the turret it is not really turning; it is milling with spindle orientation.

Now, now then! This is according to the Fanuc manual and a cnc instructor I spoke to. But thinking about it just because you cut an outside diameter with a boring head on a mill you wouldn’t necessarily call that turning, at least I would it. Anyhow thanks for the input it all gives the brain a tingle!

Check 7600 thru 7641 those are all of the polygon turning parameters on a Fanuc 18I if you have a fax number I can copy the pages and fax them to you. Just send me an E-mail and I can do that on Monday.

Oh yae as far as it being an option that I am not sure of but I am sure that the Polygon Turning comes with the live tooling option that you bought with the machine. Now I am going by our Mori's of couse maybe Daewoe might soak ya another few bucks for it. But I do have a list of 9000 option parameters I have come to own I will search at home and see if I have that one.

I thought you needed live tooling for polygon turning. If you have live tooling you will have a C axis. Machining in X and C together will produce the same result.
