- [Instructor] To finalize and clean up the core,
we're going to go through and add some final fillets in.
Now, reason why we're going to put in
these tiny little fillets,
is we want to make sure that the core
represents the final part.
That final part is going to have those tiny little fillets on.
Sharp corners are really difficult, a lot of times,
to get in the internals of a injection mold,
so, tiny little fillets need to be put on to represent.
And, when I say tiny, we're talking absolutely minuscule
like a quarter of a mil, even smaller in some cases,
but, they are there.
Now, to do so, I'm just going to go in to the actual...
Here are the Bosses.
If I go to the Remove for the Bosses, right mouse click,
Define In Work Object, you can see,
those are the faces generated by that remove.
So now, when I come in here, I'm just going to put in
half a mil, .5, you shrink that down a little bit,
move this out of the way,
and I'm just going to pick that face, and that face.
You'll notice that it picked both the top and bottom edges.
Select okay...
Next, I'm going to go to, this Remove here,
right mouse click, and Define In Work Object.
With this, I can, basically, do something similar.
I can come in here, and if I pick this face
you'll see it picks all those.
Now, if you really want to, I'm just going to cancel out,
you can go in to this Body, Define In Work Object,
and, again, it depends on the shape that you're looking for,
you may, actually, be able to simply apply that fillet.
So, there's a couple of areas that you are now able
to apply those fillets to.
If I put it on that, and then I come back up to the Remove,
right mouse click, Define In Work Object,
you can see, that some of those fillets are now in place,
especially down in the wells.
With that, I can now, pick just this top edge here, here,
and work my way around,
to place all those fillets in.
Again, it all depends on where you need
those fillets to be located.
Do you need some of those corners to be sharp?
Do you need all of them to be rounded over?
So, those are the things that are going to determine
where you place, how big,
so on and so forth, those fillets need to be.
Select okay, now, when I go back up, to my PartBody,
Define In Work Object, that core represents,
exactly, the part that's going to be used,
or the tool that's going to be used,
to make the internals for this.
If you, also, have to apply blends, or fillets,
to these corners as well, on the A side,
well that's going to have to happen
here on the outside of that part.
Okay, because, remember, this is on the A side.
The way we treat the A side's going to be a little different.
So, if we modeled the A side similar to the way
the core's been modeled, which you can do,
in a lot of cases it's not truly necessary,
'cause they're just going to take the outside face of that
and just, simply, machine to the outside face,
and that's perfectly fine.
But, in this case, we didn't model it
the way we did the core,
so we'll just go to the remove,
right mouse click, Define In Work Object,
and, add in whatever fillet sizes we need to add in.
My edge, pick my edge,
go back to my PartBody,
Define In Work Object, and just make sure that,
when you save it, and you're done with your part,
that your in work object is your final PartBody.
That way, you know the next person that comes in
and takes a look at it, knows, exactly,
that everything is set.
Everything needs to be where it needs to be.
If somebody's not familiar with Catia,
and the in work object is not the right place,
then, it can get a little tricky for
somebody that's not familiar with this.
So, always go back and do your part body
as your in work object.
Verify everything is there.
If you want to run through the
Thickness Analysis one more time,
Draft Analysis one more time,
it's always good practice to do so.
But, this is basically it, your part is now complete.
You have all the fillets, your core is designed,
and you're ready to send this off to manufacturing.
