Custom Thread Calculator (SolidWorks)

[jcoeng]

I'm looking for a custom thread calculator. I have a Machinery's Handbook but I use many non-standard threads. I have tried going through the equations etc. (about 1 year ago, don't have info now) to create a calculator and it seems that there is not enough information to fully define a thread (need to model in SolidWorks). I would like to find or make a thread calculator that can calculate basic thread dimensions for say a 12.5 x 0.75P M Profile thread.

If anyone has resources for custom thread design that they could share I would greatly appreciate it.

thank you,

Jason

KENAT,

Have you reminded yourself of faq731-376 recently, or taken a look at posting policies:

Forgot to say, for a Solid Works specific equation, since I dont' know what value it uses for the diameters (max, min, mean or some other) then I suggest asking in the SW forum.

I have a spreadsheet that does this for Solid Edge but I suspect not applicable for SW.

I have viewed that thread and did find the calculator but it is only for *UN* threads not for M profile.

I would be interested in seeing a spreadsheet for SE as regardless of software, the numbers used to define threads are same.

thank you,

That's my point, they may not be the same. Depending what value is used for the various diameters. Is it a max value, a min value or a mean or something else. For instance at one point SE was set up so that the minor diameter of a female thread was the nominal tap drill diameter.

Didn't realize you were only interested in metric, although the basic thread form is about the same.

Attatched a line from the SE one I have, I did't come up with it and if memory serves it doesn't quite match the pre-programmed SE values for some diameters but is pretty close.
