Apply assembly interference inspection tools.

00:05

After completing this video, you'll be able to

00:08

manage assembly components positioned for

00:10

interference detection and mechanical review

00:13

and use interference to check for component overlap

00:19

in fusion.

00:19

We want to get started with the supply data set sample engine,

00:22

assembly interference dot F 3D.

00:25

Under our inspect tools,

00:27

the interference detection is helpful to ensure that our

00:29

components have or don't have the appropriate amount of interference

00:34

in some instances.

00:35

We may have features like press fit bearings that

00:38

need to have a small amount of overlap.

00:40

Better understanding how components fit together in an assembly can

00:43

ensure that downstream during manufacture that everything fits correctly.

00:48

We're going to use the interference tool to

00:49

check interference between the piston and the cylinder.

00:53

Once we've selected our components, we're going to select compute,

00:57

we'll get an interference results,

00:59

dialogue and the opacity of our models will change.

01:02

Anything displayed in red is gonna be an overlap.

01:05

We can see here that we've got a fairly

01:07

large overlap between the piston and the cylinder.

01:10

If we want to double check this in another location,

01:13

then we need to drive the joints to put them in the correct position.

01:17

In this case.

01:18

For example, I'm going to double click on the revolute joint on the crank.

01:21

This is going to bring up a small dialogue. Currently, it's at 100 and 80 degrees.

01:25

I'm gonna set this at zero and hit enter.

01:28

When I do this note that the piston and the crank shaft are in the wrong orientation.

01:33

Oftentimes joints can flip depending on how they're defined,

01:38

rotating a joint and driving it in a different way can oftentimes be required.

01:43

So in some cases, you may need to rotate it slightly

01:46

double click and then add a value.

01:49

Once we're happy with the location, we can capture its position.

01:54

Once we've captured it, we can go back to interference detection

01:57

and check again for interference between the piston and the cylinder.

02:01

Once again,

02:01

you can see that these small pads on the

02:03

side of the piston are showing an interference.

02:06

I'm gonna roll back my timeline before that capture position,

02:11

I'm gonna expand my engine assembly and hide the cylinder.

02:14

And then I want to find where this feature is.

02:17

We can do this a couple of different ways.

02:19

We know that it's on the piston component.

02:21

So I'm gonna to activate the piston component.

02:24

Then I'm gonna select the face that belongs to that feature.

02:27

We can see that it's an extrude feature and

02:29

we're gonna double click and make a modification.

02:32

Currently,

02:32

this feature is a small wee pad on the side

02:35

of the piston and it was created at one millimeter.

02:37

It should have been at 0.1 millimeter

02:40

using interference detection is a great way for us to find this error.

02:44

We're gonna go back to the top level assembly

02:46

and bring back the cylinder and check for interference one more time.

02:50

Now, when we select the piston and the cylinder and we compute the interference,

02:54

we can see that there's no interference detected

02:57

using the interference detection in multiple

02:59

positions for your assemblies is a great

03:01

way to double check to make sure that there's no component overlap.

03:05

Keep in mind that in most cases,

03:07

your assemblies are designed at their nominal values.

03:10

If you are dealing with manufacturing tolerances, for example,

03:14

a plus or a minus value on the diameter of the piston,

03:17

then we would also need to make sure that we double check those values as well

03:22

at this point.

03:22

Let's go ahead and make sure that we understand how we can position our components

03:27

and also how we can use interference detection

03:30

once you're done, make sure that you do save your assembly before we move on.
