Unable to post assembly file

[jozica.golob]

Hi!

I have some questions regarding DS and animation of a boring head assembly.

When I posted the assembly file, no parts showed up on the other end.

I can open it just fine. When I extract it from a zip file, I only get one file, the assembly, no parts.

So, how do I make it so the parts will show up?

Do I create a new folder and bunch all the part(ipt.) files and the assembly(iam.) together and post the whole thing? That can't work, can it?

This shouldn't be so difficult; I don't know what's going on.

Can someone please explain exactly what I need to do.

Thanks for your help.

Kind regards.

If you are working on a project such as yours - shouldn't you already have a folder with all the files in the folder?

All you need to do is

1. Right click on the project folder and select Send to Compressed (zipped) Folder.

2. Attach the resulting *.zip file here.

If your part files are scattered all over the place (for example if you are using Content Center parts) the go to File>Save As>Pack and Go to have the software gather everything together in one place for you.

Imagine this is the real world with real parts.

You want to put together an assembly.

You go out into the warehouse and collect all of the parts into a box to transport to your workbench.

In the computer world - the folder is your box.

You put all of your parts in the box (folder) to make it easy to transport them all at once (and, simply to keep track of them so that you don't lose any).

If you want to send the assembly to someone else you put all of the parts into a box (either separately or some assembly required or fully assembled) to make it easy to ship to them (or in this case to attach to a internet forum).  Amazon.com has become very good at this.  Imagine getting your box from Amazon without all of the parts....

1. Open the assembly.

2. 

3. 

4.

Hi JD!

Finally! 

Thank you for your gracious reply.

I had absolutely no idea about Inventor projects. Had to watch a video to set it up. It makes a lot of sense.

So here it is, I hope it's all there.

Regarding the questions from my previous post; in DS, the assembly is over constrained. How do I fix it? Maybe deriving the feed collar and the rack and combining them? In animation, when I turn the spindle via angle constraint, it flings out the cross slide.

Thanks again.

Before I start analyzing this I have a question for you -

How much experience do you have running a milling machine or lathe?

If you have experience, what is the first thing you do when setting up a job to run on mill or lathe?

(Answer: Set up a zero position - a datum from which all machine adjustments are referenced.)

I noticed that in many of your sketches you did not do this.

Use the Origin Center Point and fully define your geometry.

Edit: As I go through this it looks like you sort of have the right idea about using the origin, but I dimension or constrain everything - no surprises as I make edits to geometry.

[JDMather]

A lot of your parts make reference to derived from a missing assembly.

Not sure I would have done this.

I recommend that you use sub-assemblies within your main assembly (just like the real world).

[JDMather]

On some of your sketches there are obviously missing dimensions that would be needed to make the part, but when I add the missing dimensions - the geometry is perfect.

How are you creating perfect geometry without dimensions?

[JDMather]

Some of the geometry looks impossible to manufacture (or very expensive).

I notice the material is not assigned.

Inventor Dynamic Simulation takes into account the mass of components.

[JDMather]

I would have placed this casing as my first component in the assembly.

When placing the first component I would right click and select Grounded at Origin so that the orientation is on the assembly axis.

( I would set so that Z axis is centerline of assembly - just like on the machine tool, although this isn't really required.)

Your assembly is at an angle relative to the origin.

[jozica.golob]

I have very little experience on the lathe or mill; even if the parts were corrected for easier manufacture, it would take a very well equipped machine shop to make it. Someday maybe, if I'm stubborn enough.

I got the perfect geometry by drawing a sketch over the parts(cross slide-tool block), copying the sketch and pasting it in a new part file.

Thanks.

That's an excellent job, Rok. Congratulations.

I've added some sub-assys and changed some constraints. Only the updated 2016 files are attached in first Zip. The remaining files are in Update2, so new readers don't need to download Rok's data.

You can test 2 situations:

a) Cutting tool movement alone by driving Verstellwinkel (Default Posrep). Because of the large worm gear ratio only small velocity can be seen.

b) Cutting tool moves together with spindle by driving Verstellwinkel (Position1). Sad to see, that now the tool is moving much too fast (@johnson.shiue)

Surprise! That's what I get when trying to insert additional gear joints.

Blind walking through the menu opens normal behavior.

Inventor re-start didn't help.

[JDMather]

Try going into Tools>Application Options>Hardware tab and set to software graphics.

[WHolzwarth]

No change, Jeffrey.

[JDMather]

Hmmm,

We have been using DS a lot the past 30 weeks and have not run into that issue.

I will have to experiment with this dataset.

Do they come back if you open another assembly?

[WHolzwarth]

New Windows 7 re-boot did it.

[WHolzwarth]

Hmm. Now I'm in DS, trying to activate the movements one after another.

First two rolling joints are moving ok. But Gewindebuchse mit Axiallager.iam does not only a worm wheel rotation, but an additional screwing axial movement.

And this combination seems to be not possible in DS.

New IAM attached

Hi Walter!

Thanks for your effort.

I also got some wierd hiccups trying to drive the angle constraint. The power is cutting out, there's 15+ cm of snow here.

About the DS; you don't suppose a screw joint would work for the worm wheel? I would really like to make the thing work in DS as one complete mechanism. 

I'm out of my depth here.

Screw joint alone would be ok, Rok. But the worm gear joint seems to be not lucky with the axial movement of the worm, induced by the screw.

Ok, here we go. It's been no easy task for me.

Best way for watching is wireframe view with Gehäuse mit Kegelrollenlagern and Gewindebuchse mit Axiallagern set invisible.

Only changed files after my last upload are in Zip
