Method for milling thread.

Method for milling thread.

(OP)
What method(operation type) is the best for milling thread (in one pass)?

Take a look at the picture in the attachment.

RE: Method for milling thread.

What version of NX?

Do you need a machining answer or modelling?

What is the scale of the picture length and Outside Diameter are enough to describe it.

From a process point of view Lathe Thread Roller Thread grinder or even a milled 4th approach might be applicable. What is you're preference and why would you just thread cut it using lathe?

Best Regards

Hello hudson888.

- NX6
- machining
- lenght 12mm diameter 4mm
- it's impossible to use lathe becase of material - Zirconium oxide It is very fragile before baking, so I use XZC mill and made profile with method "VARIABLE CONTOURE" with SURFACE AREA as drive options. The same method I tried to use for thread but with no result.

Bailar,

For these situations we drive the tool using a modeled helix curve. I'm not at work so I'll post a prt file on Monday.

It would be great! Bill.

RE: Method for milling thread.

With a 4th Axis on the machine that's more of less what we used too.

RE: Method for milling thread.

Bailar,

You may be able to us a thread milling operation.  See the atteched part.
There is a thread mill operation as well as a fixed contour using a helix as the drive curve.

You did not say what the pitch of the thread is.
Thread milling is not your "standard" operation.  It is actualy a UG Open routine and is quirkey.  However it does work once you have all the parameters defined correctly.  It uses the feature information from the Symbolic Thread feature.
