Design changes for manufacturing

00:02

In this video, will make design changes for manufacturing.

00:06

After completing this step, you'll be able to use delete to remove fillets, modified design parameters and use chamfer.

00:15

In fusion 360, we're going to get started with gear housing, front cover only.

00:20

We're going to take a look at this design and we're going to be setting it up for manufacturer.

00:24

So as we look at this design and we take a look at some of the details, we notice that there are,

00:30

some areas, there are counter bores, there are champers, there are other things that we really need to take a look at,

00:37

and see if they're required in our manufacturing model.

00:40

The first thing that I want to do is I want to take a look at this backside.

00:45

Now this is going to be the exposed side and I'm calling it the backside because all of the non critical features are here.

00:52

These are simply areas that are giving us a wall thickness to hold on to the bearings that are going to get placed in the design.

00:58

What we really need to consider is in the final design, is this an aesthetic thing or can it be modified to simplify manufacturer.

01:07

And the reason I say that is because with all of these features on the back side or this side that we're looking at,

01:14

when we machine from the other side and we get all of the critical details such as the areas for the shafts and the bearings,

01:21

well, the rest of it is really just cosmetic at that point and we could machine this entire part from one side.

01:29

So if that is true then it's probably best to modify the other side, if we don't really need those details there.

01:37

So we're going to assume that we've got some design liberties here and we're able to take a look at some of the direct modeling tools that we have,

01:45

to get this thing a little bit closer to ready to produce.

01:48

So let's rotate it around and let's get onto a front view and I'm going to zoom out and I'm going to rotate it slightly.

01:56

I'm going to be taking a look at press pull and I'm going to select the top face of the design.

02:02

I'm going to begin to pull this up and then with the dimension dialog still highlighted, I'm going to select the top face of this boar,

02:10

when I do that, I'm going to select "OK" and notice how it left a small scene here.

02:17

Now, the reason it left a small seam is because this is actually a metric designed part and we're looking at it with the unit set to inch.

02:26

So there is going to be a number of decimal places that end up getting rounded, which means that we're a little bit off in terms of this geometry.

02:35

Now it doesn't look that bad, but there is a face division, which means it might be harder for us to manufacture.

02:42

So what I'm gonna do is I'm actually going to start by selecting all of these inside bores holding down the shift key.

02:50

And then I'm going to use modify and delete to bring them all up to the top face.

02:55

Then I'm going to select this entire face and use modify and delete and notice that it's not able to do it.

03:02

But if I select the smaller face and select modify, delete, notice that it gets rid of that entire thing.

03:09

But that's not really what we want to do because we need that geometry.

03:14

So, we need to go in and we need to zoom way in until we find this small side face and it's kind of hard to see, kinda hard to grab.

03:23

But what we want to do is we want to figure out what that actually is.

03:28

Sometimes it can be easier if we go to a true Ortho graphic view and we get rid of that perspective.

03:33

It can be easier to zoom in and actually select that face.

03:37

Also sometimes the material can make this a little bit more difficult but I'm going to hold my mouse over there.

03:42

I'm going to hold down the left mouse button and I'm going to go until I select that small face.

03:48

Another way that we could do this is actually use metric values but sometimes you don't really have that option.

03:53

With that selected, I'm going to hold down the shift key and select this and then I'll go back to modify and delete.

03:60

So that is able to get rid of that small difference between those two faces,

04:05

and again, it's really just a product of the difference between metric and standard when we're rounding those units.

04:12

I like to see perspective you with Ortho graphic faces.

04:16

I'm going to go back to that camera mode but you can always carry on with just an Ortho graphic view.

04:21

Now that we've used press poll and we've used delete to modify the backside.

04:26

Let's take a look at some of the other geometry that we may or may not need because this is a reflective part.

04:32

There are going to be some views when you start to rotate this around that make it a bit easier.

04:38

Now, if you want to simplify the color scheme, you can always go to inspect and component color cycling,

04:43

and if you don't like that color you can always right click on the component and cycle the color until you get to another color.

04:50

These are going to be more of a flat pastel style color.

04:54

You can always go back and turn that on or off at any point in time.

04:57

It really helps when we're dealing with a lot of assemblies.

05:00

So at this point we know that we've got a champ for on all these corners and while we can machine the champ for with it actually in the model,

05:10

we can do it without it in the model as well and simply decide what we need there.

05:14

When we're looking at this, the champ for is really just there to ease the assembly of bearing or a shaft, something that gets pressed in.

05:24

So the actual size of it may or may not be critical.

05:27

So what I'm going to do is I'm going to select all of these chamfers,

05:32

and again holding down the shift key and then we can use delete on the keyboard or go to modify and delete to simply get rid of them.

05:40

And the main geometry, we need the boars and this whole it goes all the way through. Those are all still there.

05:46

But now what we have is a simplified version of this model that lets us go in and grab the edges that we need,

05:54

grab a nice smooth face division if we need to face the backside before we flip it over.

05:59

And all that information is much cleaner than if we have a bunch of chamfers or a bunch of extra edges that we don't really need.

06:06

So at this point let's make sure that we save the design,

06:11

and it's always a good idea to save often because we can always go back to previous versions.

06:17

Now that we've saved it,

06:19

let's say that maybe we just wanted to change the size of the chamfer before it was a metric part and maybe it was just a little bit more difficult.

06:27

So now we're going to go back and we're going to add our own chamfer.

06:31

We're going to select all the edges that were tampered before.

06:35

And we're simply going to manually put .05 as our chamfer edge.

06:40

Notice when we do that, we're getting a warning, it's telling us that it couldn't be created.

06:45

It's telling us that it's basically it's just too big.

06:48

So we can go smaller .01 and you see that's more in line with the size of the features that we're working with.

06:55

So now that we've added that, let's go and select "OK".

06:58

Go back to home view and let's save one more time before moving on to the next step.
