Chamfer edges

00:02

Champ for edges.

00:04

After completing this video, you'll be able to

00:07

use Chamfer to deer

00:08

all edges of the caliper

00:12

in Fusion 3 60. Let's carry on with the data set. From our previous example.

00:16

At this point, we need to take care of some of the final finishing operations.

00:20

We've done our two D adaptive to remove the top hat.

00:23

We've used facing to go all the way down to the top of our part.

00:26

We've used our 3D adaptive to rough the rest of the

00:29

caliper out our two D pocket to finish off the various faces

00:33

and a two D contour to finish off the mounting tabs and

00:36

then a two D bore to take care of our counter bore.

00:40

At this stage, we really have our champ on the top of the piston or the button area.

00:45

And then we also have to deer

00:47

the rest of the hard edges

00:49

while some of this detail is not included on a detailed drawing or in the 3D model.

00:54

Oftentimes you'll see notes like break all edges or a specific

00:58

champ amount that you need to use on all sharp corners.

01:01

Very rarely will you have a 3D model that you machine

01:05

that will not have some sort of deer

01:07

or champ on all of the sharp edges.

01:10

So make sure that you do take a close look

01:12

at any prints or models that you are machining.

01:15

In some cases, you might have a model champ.

01:18

And in this case, when we take a look at using tools like a two D champ for tool path,

01:23

we can set the value for our champ for width at zero based on our selection.

01:28

So the first thing that we need to do

01:29

is make sure that we're using the appropriate tool.

01:31

In this case, tool number two, which is our champ for

01:34

MLL

01:35

for our geometry. We're gonna select the top edge

01:38

and then when we move on to our passes section,

01:42

the champ for width value is gonna be zero.

01:44

Whenever we have a model champ,

01:46

that width value will be zero.

01:48

If we have a sharp corner,

01:50

then the width value is gonna be the width of whatever champ or

01:53

deeper we want to use

01:55

the tip offset again,

01:56

is gonna dictate how far down the tip of the tool is gonna drop below our edge.

02:01

In this case,

02:02

we need to be careful and make sure that this amount

02:05

is going to be large enough for whatever tool we have

02:08

for ours.

02:09

We're gonna set this at 0.06 and we can leave the chan for clearance at 0.025 and say,

02:15

OK.

02:16

Using in process stock, we want to validate the champ

02:19

to make sure that it works and we can see exactly where the center of the tool is.

02:23

Remember that we have options to turn on and show the tool on cursor.

02:27

So you can hold the tool here and you can make

02:30

sure that you are cutting with the tool far enough down.

02:33

In this case, I might want to increase that offset.

02:36

So I'm a little bit higher up on the tool,

02:38

gonna toggle off the show tool on cursor which is also control and t

02:42

right. Click on the tool path and make an edit

02:45

this time. Instead of using 0.06 I'm gonna set this 2.09 and regenerate

02:51

once more,

02:52

we can go back down and show the tool and just make sure

02:55

that we're not being too high or too low on that Chamfer Mill.

02:59

Again,

02:59

there are reasons why we want to dictate where

03:01

this happens on the position of our tool.

03:04

In this case,

03:05

we wanna make sure we're not too far down because then we're

03:07

getting outside of where the cutting flutes are or too far up.

03:11

It will also change the surface speed of the tool on the part.

03:15

So again, it's important that we are in a correct area of the tool whenever possible.

03:21

The next thing that we need to do is we need to add a two D Chamfer that will allow us to

03:25

deeper, all the sharp corners.

03:27

So from the two D menu, once more, we're gonna select two D champ

03:30

using the same tool,

03:32

we're gonna select the outside and all the inside edges of all the holes

03:37

we're gonna move our way around

03:40

and note that as we rotate the model around,

03:42

we also want to take care of the geometry on the backside.

03:46

Remember that we used a Bullnose mill to finish off this corner,

03:49

which means there is a small filet in that area

03:52

for our geometry. We need to make sure in the passes section that we do enter whatever

03:57

cham

03:57

width we want. In this case, 0.01 a relatively small debt,

04:02

the champ for tip offset. Again, this is going to be critical.

04:05

We need to make sure that we are using a

04:08

portion of the tool that can actually clear the surrounding geometry

04:12

for us. Again, I'm gonna go down to 0.09 for the tip offset and say, OK,

04:17

we'll be able to get a preview on the screen and see

04:20

exactly where the deeper or the chand tool path is cutting.

04:24

We can see it is able to cut all the way around here.

04:26

And if we look down here,

04:28

it's able to cut into that small filet that was left by the Bullnose Mill.

04:32

Everything so far looks pretty good.

04:35

I'm happy with the results. So I'm gonna go back to a home view,

04:39

gonna click on the activate option to go back to my name,

04:42

view and make sure that I save this before moving on.
