Acme Thread in SolidWorks

[@MrChaso123]

I followed this exact procedure, and it worked great. However, I have 19 more of the exact same holes I want the same exact thread in. What’s a slick way to apply what I’ve done to all 20 total holes?

[@DanAbbott-SMCC]

If the holes are applied as a pattern you can apply these features to the pattern by moving it before you created the hole pattern. It is possible to create a custom thread profile, which would make things a little more streamlined if the holes were not placed as a pattern. Here is a good description of how: support.hawkridgesys.com/hc/en-us/articles/4419921661197-Creating-Custom-Thread-Tool-Profiles-in-Solidworks- It may be possible to save the threaded hole as a library feature, but I've never tried it, so I can't vouch for it. Here's a link to a description on saving library features though. I will try it myself if I get some time. help.solidworks.com/2021/English/SolidWorks/sldworks/c_library_features.htm

Thanks. Making that ref. plane normal to the helix was the trick. very nice expiation. I agree with @mostsoot it does sound like a 3D printer printing a curved or circular outer/inner wall. Ha. ("inexpensive" stepper motor resonance is pretty obvious...) I actually thought the same when I first watched your video... :) Anyway, the dimensions on your trapezoid are for LMC (largest hole) conditions? Nominally, that root depth is 0.5 * pitch (0.5 * 1/6 = 0.0833 - you use 0.0933)?

You're welcome. I am not sure what that noise is, and I agree that it sounds like a 3D printer. I have 10 printers, but they are at work. I made this video in my home office, where I do not have a printer. The only thing I have in here that makes noise is two EGO battery chargers, but I wouldn't have made a video while charging those batteries because it is very noisy. Perhaps some radio frequency problem? I found some differing dimensions for acme threads. I think I used the Machinery's Handbook, but can't remember anymore and it may have been a typo. Obviously, you could modify those dimensions. The purpose of the video was just to show a student how to create a thread using a profile and a helix. The thread tool in SolidWorks doesn't always give a true thread in my experience, so when I do want to create one for 3D printing something with a thread, I usually create the thread this way and reduce the size of an external or increase the size of an internal thread and modify it if it doesn't work.

[@mostsoot]

is that 3D printer sound on background :)

[@DanAbbott-SMCC]

I hadn't noticed the background noise, but no, it is a charger for a EGO battery for my snow blower (or chainsaw, or hedge trimmer, or string trimmer, or lawn mower -- I am a fan).

@@DanAbbott-SMCC come on its cheap stepper motors drivers sound in the background 7:32

I made this in my home office, where the only printer is a laser. Whatever it sounds like, it isn't a 3D printer.
