4th axis threading

[rchipper]

Hello,

 

Can anyone share with me how to program a thread using a 4th axis Haas rotary indexer conected to a Haas Mini mill. In a pickle, need help.

Is it a rotary or is it an indexer. There IS a difference.

_{I'm sorry, it is a rotary, full 4th axis.}

Basically I would like to use a 3mm ball end mill in the spindle, locate at a print specific start point for the thread in X and Y, drop down in Z

to thread depth. Then start A axis rotation and X movement simultaniously to specific end point for thread.

 

Does this help?

Hello,

 

How do I attach a file? This does not appear the same as I remember it. What have I done.

Click on the "MOre Reply Options". You get the attach file option there.

[rchipper]

Right on.

 

Any how here is a generic sketch of what I am trying to learn to do.

Damn I just programmed this thing and realized your on X5. Well anyway, all you have to do is draw the thread un-roled, creat a simple contour and set axis sub roll dia to your minor dia. If you dont do full fourth work, make sure your rotary is setup correctly in your machine def.

Edit: Rotar dia is not set correctly on this pic or file to get the orientation you need. But you get the idea.

JParis,

 

Very nice. I see what you did and appreciate you taking the the time to help a NEW guy. I do have a question, I followed the calculations that you forwarded but I am getting dif. results: Blue line 45.3897= 1.806(thd minor), x 8 rotations x 4(.250 pitch).

I am getting 57.792. Am I not doing this correctly?

No, just did it again, I get the original number

 

1.806 * 8 = 14.448

14.448 * 3.1416 = 45.3898

 

In this case you have 8 full rotations of the helix the 1.806 is the minor Ø the 8 is the number of twists, take that value and multiply by "pi" (3.1416) which will give you a straight line length of the helix laid out straight

FYI, Haas makes almost no indexers.

there is only one Haas brand model that comes to mind that indexes and it is a comparative monster.

even their lat 80's 5c model could interpolate. did it on a Hitachi with m code triggering the programmable box.

They mention "Indexers" OFTEN on their website. Found bunch right here - http://www.haascnc.c...ROTARY#contbody

 

Strange that most if the indexers are of the 5C variety you mentioned. Odd.

If you read the description in all of those "indexers" they are all full rotary, not sure why they call them indexers.

I believe it's actually the "control" until that determines what it is capable of. I think the Tables/Collet are all capable of whatever the end user wants to do, it's just a matter of buying the more capable control unit or the less capable control unit.
