I want to create an extruded hole with internal threads.
Can SW do the calculations for the pilot hole required?
How do I extruded the hole in the sheet metal?
the hole wizard will do that
Good morning Carl,
If you want to show the actual thread then do it in the flat pattern and it should show when you fold it back up again,
Do you have a sample file??
I do not have a sample file, because I don't know how to create it.
I was searching online and found a program called CATIA. In this program there appears to be a dialog box to plug in dimensions of the finished extruded hole allowing the software to create the sheet metal feature.
Is SW capable of this?
Do you need the actual start and stop showing in your part or would the cosmetic visual be ok.
If you need it in the actual part then there are a few steps to go through, Create a Helix with the pitch etc.. Create an Extrude Cut with the profile of a cut thread, following the Helix curve.
If you just need the Cosmetic Visual then use the Hole Wizard,
Do you have 2012 ??
We are using 2011. I was not aware 2012 was out yet. I’ll look into that later.
Here is the best I could do for a sample.
When I try to flatten the part the extrusion will not flatten.
Good afternoon Carl,
SW flattens sheet metal features, which would be either rolling or bend with a striaght press brake die, what you show is a stamping and that is a lot more difficult to calculate.
If you were to make a part like you show and do a sectional cut in the center of the hole, you would notice the different thickness at the hole area.
Did you try the hole wizard?
Not a lot of help is it......
I know I'm not really answering your question, but this isn't an apples to apples comparison though. CATIA is made by the parent company that makes SolidWorks and it's in a completely different tier as far as price, capability and purpose is concerned. If you have the budget (both time and financially) for CATIA then... go for it? My recommendation is that you figure out exactly what your needs are and then look for a software package that best meets this, as opposed to trying to force a software package to work by coming up with a plethora of work arounds.
Expanding on John's suggestion, which is a very valid one, keep in mind that the more micro level features you add the higher your overhead in terms of the complexity of the model. If this is what you need on a regular basis, you might want to reanalyze your software decisions.
As far as your attached file is concerned, SolidWorks won't flatten that type of feature. The sheet metal module works with simple bends so things like that, or turning parts doesn't work as one would want or expect.
If you are adamant about SolidWorks and you don't do this type of feature often, here's what I would do (in general as applying it to this example is a bit moot):
Take your part with the extrude and make a new configuration that suppresses it. For the flat pattern use that configuration. For the drawing use the original one.
I think there is a modeling error. Both fillets have the same Radius
There should be at least difference of material thickness between fillets (if considered no thinning) where as in this model thickness has increased.
Check the extrusion volume;
Volume=30.709 cubic millimeters
Flat blank (no pilot hole) Volume=29.905 cubic millimeters
So even without a Pilot hole, the extrusion contains extra material.
I didn't realize the discrepancy in the radii. Thanks for pointing this out.
I ended up doing the calculation by hand to find the proper pilot depth to obtain the diameter I needed.
I am still learning how SW functions and I know there are many functions I am unaware of.
I guess extruded hole calculations is not one of them.
Thanks so much for the advice.
Also, in the second picture, how did you show color relative to material thickness?
Also check the attached model's Configurations.
