I need help converting 3d file for CNC machining.

[TxBabyHuey]

So the guy at the toy company wants us to try to get the Identity Disc CNC'ed.

We have a budget but it's flexible. The aluminum is going to cost about $120 and we are trying to stay in the range of $400-$500 for the whole disc to be machined or lasered out.

I have the file all ready as an .obj but I can also export it as an .stl.

The .obj is saved as quads and the .stl saves in triangles.

I would rather have someone help me convert the file from an .obj.

But if someone can help I would really appreciate it.

The guy at the toy company has a 3d printer that can print in plastic which for us I would think would be ideal because after he prints it he will have to clean it up. It will be a lot easier to clean up a plastic model than a aluminum model.

Even with the aluminum model he would have to make a mold, then shoot one out and clean that up.

And after we CNC it out of aluminum I will still have to ship it to california and he will still have to clean it up.

So I basically need to get a quote from Rebel Scums guy and the ones I was exporting from Maya were turning into rats nests.

Someone has to be able to help. And if someone lives in the Southern california area who can possibly CNC this out it would be two birds with one stone.

We are still trying to get him to print it there but I definitely need a backup.

Once again here is the disc. There will be a disc, the rings, and the backing.

Little " fuzzy " on what you need done ?

I can help you with a conversion, but if you have
Rhino you can export out ot STL with that...

Provided whomever built the Disk made it watertight
to begin with ? Also, not sure how this design works ?

When you compare the third image with the first I am wondering
how you are doing this ? Are the slotted out area's in the
third image going to be " capped " by the rings in the top image ?

Which would mean the Rings { in BLUE } would need to be made separately
but not shown as seperate pieces ?

You can PM me if you need some help...

yea i'm confused... why don't you just use the stl and print it from that?

 

[Rebelscum]

I *think* it's because if he wants to cnc it the cnc programming doesn't support .stl.

 

[TxBabyHuey]

Yeah I shot the .stl file to Phil's guy who has a cnc machine and it came out as a rats nest.

So the rings are separate and will be about .25" inch thick and will be cut out of it's own piece of aluminum.

Honest I don't care if it is cut out of wood, I would rather have that.

So the disc itself will be 1.5" thick and 10.5" wide.

Yeah the rings just sit in those cavities and I created these lips for them to sit in.

The toy company will have to clean these up anyway so I don't mind if there will be cnc marks.

The file of the disc itself is in quads. When I export as an .stl it becomes triangles.

So I have never worked with a CNC program before but I would rather it be exported as quads.

I am shooting Wolvster a pm here in a minute

PM replied too..

But so you know, converting it to STL format it WILL
convert all quads to triangles. You don't have any choice
in the matter there... If you bring the files BACK as OBJ's
you will see what I mean...

Also, not sure what you mean by " rats nest " ?

Again, this might have something to do with what
file TYPE the CNC machine requires to cut your parts ?

Well I export from .obj to .dxf if I am not mistaken.

When I sent Rebel Scum the file from a .dxf his guy opened it and it was apparently all over the place, as is the points were just pointing in obscure directions and the file was screwed.

His guy said that a .dxf file was acceptable but not ideal, as a .stl is not ideal.

I believe the file they need is a studio file. So from Maya (the program I used to model it) I can export as an .obj, .stl, but I was hoping someone can take the .obj and export it in another program so there are no issues.

pm sent

 

[TxBabyHuey]

Emailing you the file now...

Let me know how it goes.

I really am hoping someone can convert the .obj file.

Once again I have never messed with a CNC studio program, if I send a low polygynal model can those programs smooth?
