I could not find any information regarding generating multiple thread starts, so I decided to post this tutorial.
-multiple thread starts is widely used in manual screw press and even bottle lids.
How to create a two or more thread starts in Solidworks:
Answered with a tutorial: https://grabcad.com/tutorials/how-to-model-a-two-or-more-thread-starts-in-solidworks
Here is the finished parts, it's working perfectly by the way.
what kind of thread is this...?
I believe it's referred to as a triple stub thread
See the pictures I uploaded, all the parts are working perfectly, it's the same as the shown in the tutorial.
but see that is not well done, I'm not sure since it is not good in the photo details
This is a special thread base on the standard ISO metric thread, I'll add some photos when they finish machining the parts.
