Create a 3D scallop toolpath on a fillet

00:02

In this lesson, we're going to create a 3D scallop toolpath on a fillet.

00:07

After completing this lesson, you'll be able to: Create a 3D scallop toolpath and use Avoid Touch Surfaces.

00:15

For this lesson, we’ll be using our fsae rim front setup.

00:19

We've already taken a look at clearing out the majority of the material using 2D and 3D contours as well as a 3D scallop to clean out a flat area.

00:29

But now we want to talk about using a 3D scallop to clean out an external or an external edge fillet.

00:36

Now these are two different approaches or uses to the scallop operation.

00:40

So we want to make sure that we understand the differences that we need to go through when we're setting them up.

00:45

To get started, we're going to use our 3D drop-down and select Scallop.

00:49

We'll be using that same 1/4” ball and again aluminum finishing.

00:54

For our geometry in this case, what we're going to be using is Avoid Touch Surfaces, but specifically we want to use touch surfaces.

01:03

This means that we're going to select specific areas that we want to focus on.

01:08

And in this case, we want to make sure that we're selecting just the surfaces of interest.

01:14

If you make too many selections, if you accidentally select the entire body,

01:18

then make sure that you restart your selection and you only grab the surfaces.

01:23

Whenever you hover the cursor over an edge, it will try to default to selecting the entire body.

01:29

So we need to make sure that we are using just those faces.

01:34

I also want to note that some of the options that get turned on by default, such as machine areas using boundaries.

01:41

So I want that to be my option because I'm not going to actually select a machining boundary.

01:46

I want to use these surfaces.

01:48

And I'm going to change my boundary overlap to be 0.125, that's half of my tool.

01:54

And I want to allow the tool to move around and have enough freedom to be able to cut that geometry.

01:60

In the Passes section, I also want to make some adjustments to this default value for stepover.

02:05

I'm going to use a relatively small value because we're dealing with a small external fillet.

02:11

I'm going to have to make a lot of passes to clean that up.

02:15

We're gonna say OK, and allow it to generate. So you can see that the scallop is moving back and forth along those surfaces based on our selection.

02:24

This is a great way to clean up this fillet.

02:26

But let's take a look at Simulate to make sure that it works as we assume.

02:31

I'm going to hit Play and allow it to move back and forth and just take a look at how it's cutting the geometry.

02:38

We can speed it up and you can see that it's moving back and forth cleaning up that based on those passes we set.

02:44

What we want to make sure happens here is that the tool cuts all the way down the fillet.

02:50

Everything looks pretty good, there's a small remnant here, but I'm pretty happy with the results.

02:55

We can spend a little bit more time adjusting some of those settings,

02:59

but this is a great first pass for this operation and allowing it to clean up that geometry.

03:05

If we do want to make any adjustments, we can extend that boundary just a little bit more and we have 0.125.

03:13

We can maybe take it up to 0.15, a little bit more than half of that tool.

03:17

That should allow the tool to go just a little bit farther and clean up that geometry.

03:22

So once again, I'm happy with the results.

03:24

Everything looks pretty good.

03:26

And inside of this in-process stock, we can turn off the cutting moves and take a look at the results.

03:32

The resolution from in-process stock is going to be lower.

03:35

The mess generated is going to be lower than that in Simulate.

03:39

So when we're looking at this, we shouldn't be too concerned with the surface finish here, but more in the fact that the geometry has been machined.

03:47

We haven't made any adjustments to the toolpath past those initial selections.

03:51

And again, I'm happy with this result.

03:53

So I'm going to go back to more of an isometric view.

03:56

I'm gonna fit to screen and I'm going to save this so I can move on to my next step.
