Ready to manufacture files

00:02

In this video, we'll look at ready to manufacture files.

00:07

After completing this step, you'll be able to use delete to clean up face divisions, inspect hole sizes,

00:12

modify physical materials and create design comments.

00:18

In fusion 360, we're going to start with coupler for mill prep.

00:22

Often times when we talk about ready for manufacture files, it doesn't just mean the overall geometry,

00:29

but in this case you'll notice that there are some face divisions and these can make it much harder for us to select geometry to machine.

00:37

In fusion 360, we might select a face and in order to have that face machine all the geometry we need,

00:43

we want to get rid of these face divisions.

00:46

Oftentimes also when we have to fill it in the bottom corner,

00:50

it's just easier for us to select an edge at the base and use something like a bull nose mill.

00:56

So in this case we're going to take a look at creating some finishing operations to get this file ready for manufacture.

01:04

To get started, I'm going to select this face division and delete on the keyboard.

01:09

Fusion 360 removes the material and then patches the surrounding geometry.

01:14

That makes it much easier for us.

01:17

The next thing that I want to do is I want to go through and select these fillets at the base of the design.

01:23

And once again, this can be problematic because we do need to move around the design,

01:28

and make sure that we don't accidentally select just a single edge and then have to go back and do it all over again.

01:34

So again, we'll hit delete on the keyboard and then we'll go through and we'll select all the other fillets.

01:40

Going to rotate this around zoom in while holding the shift or the control or command keys and then remove those.

01:48

This can be done on all the different edges. And then we'll make sure that we remove this chamfer as well.

01:56

The last thing that we need to remove from this design is the spline on the back side.

02:01

Now in reality the spine is going to be done as a secondary operation using something like a broach.

02:08

But we don't really need the splines inside of the design.

02:11

We want to kind of remove them and then we'll leave a note for what that geometry should be.

02:16

So I'm going to start a new sketch and I'm going to select this top face will create a sketch and use a center diameter circle.

02:24

I'm going to draw a circle that's slightly larger than the splines and then I'm going to draw one that's a little bit smaller.

02:30

Going to make the inside one 8.5 millimeters. And we'll dimension the outside one at 10 millimeters.

02:38

Then we can finish the sketch and we can create an extrude.

02:42

We do want to make sure that we select all the different areas,

02:46

and this can often be problematic but we can also go through back to a view and select everything.

02:54

So once again we'll drag through, you might need to hold down the shift key to make sure you're adding to the geometry.

03:00

And then we can use control or command to simply remove the inside.

03:05

We're then going to drag this down.

03:09

Instead of going to distance, we're going to select to object and select this face and will join the material.

03:15

So now we've added all that material back. I'm going to select this face, go to my comments and capture an image.

03:22

I want to add a comment that gives us information such as 8.5 millimeter I.D. 10 millimeter O.D,

03:32

Spline count 12.

03:36

So now when I post this comment, if somebody comes back and looks at it, they'll be able to see the image in the highlighted face.

03:43

We should also add a few more comments.

03:46

Since we removed the fillets from the base of this design, we need to make sure that we select this edge.

03:52

I'm gonna go ahead and just select a few edges here.

03:56

I'm going to zoom in and I want to capture that image.

04:01

So for this I'm going to say that we want to add a small fillet.

04:05

So I'm going to say use bull nose mill with 0.5 millimeter rad for radius.

04:15

We also want to make sure that we capture information about that chamfer that we removed.

04:18

So once again we'll select that edge, capture an image, and we'll say break all sharps.

04:27

That chamfer was really there just to make sure that we didn't have a sharp edge that would cut any rubber dampers that go between these.

04:35

So once again we can go through and remove all these fillets.

04:37

But this is a great place for us to make sure that we also understand physical materials.

04:43

Inside of the coupler, we're going to right click and select properties.

04:47

Right now, the coupler has an aluminum material and it's anodized blue.

04:52

If we take a look at physical, notice that we have a mass of 22.391 grams.

05:00

Let's go ahead and take a look at what that physical material is by right clicking on the coupler and going to physical material.

05:08

It'll tell us that in this design we have an anodized blue aluminum but if we wanted to make an adjustment,

05:14

maybe the aluminum generic name wasn't enough for us.

05:18

We needed to make sure that we had a specific aluminum. for example, a 7075.

05:24

We can drag and drop that on our design close and then take a look at the properties once more.

05:31

Now you can see that we have aluminum 7075 but we lost that anodized blue appearance.

05:37

If that appearance is critical,

05:39

we can always go back and add the appearance by simply dragging and dropping the blue anodized that's still in this design.

05:47

When we do that, it doesn't affect the material properties. It's only overlaying that appearance.

05:52

So you can see here that aluminum 7075 is still the material name and now the appearances that blue anodized.

06:01

So this is a great way for us to capture that information.

06:04

And even though it isn't strictly required for the manufacturing step, it is important that we capture as much critical data as possible.

06:12

The last thing that I do want to mention is that this part can be manufactured in several different ways.

06:18

We could use this on CNC lathes with C axis operations to create these off axis cutting geometries.

06:26

We could also use it on a mill in multiple orientations or this part could be cast and just final machine.

06:33

Or maybe the casting is close enough because it is holding between rubber dampers and isolating that torque,

06:41

That really means that the dimensions likely aren't that critical with the exception of the spline, which can always be machined after the fact.

06:49

So let's go back to our home view for this design and let's make sure that we save it before we move on.
