If you go to Throlabs website (this is a US company from where we can buy components), they use some non-standard threads in their parts. Checout this link https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3393&tabname=threading%20specs, and they provide the specs of SM2 Internal thread in which I'm interested. I need to create a custom part which will have internal SM2 thread in it , so that I can connect a part like this (note this has external SM2 threads) to my custom part which will have internal SM2 thread.
I am unable to find anywhere on youtube or on this forum that how can I define such custom thread in solidworks? Can anyone please help?
Note: I'm using SOLIDWORKS 2015.
Here are the specs of internal SM2 thread:
They are using a standard unified thread, just with a non-standard diameter and pitch. Assuming your are having a machinist that knows how to make threads do your part all you need to do is call out the thread designation 2.035" -40 UNS-2B and they should be able to make it.
As for modeling you would do it just like you do a normal UNC or UNF thread, just use the 40 pitch and 2.0188 ID diameter.
