Let's return to the Knife part.
00:16
We managed to nest it properly and give it a sufficient distance between the parts with enough material left.
00:25
But how can we get the detail that we want in the final part?
00:31
In order to do that, we bring the sheet through the "Create 3D Model" command to an Inventor Assembly.
00:39
I use the defaults here.
00:46
From here, we can go to the CAM environment and create some setups.
00:54
The fact that the part has such intricate details like grooves,
00:58
and there are steps in there and holes means that I cannot finish this part with a cutting operation or a cutting setup alone.
01:08
So it needs to be a mix of milling setups and a cutting setup.
01:14
So my first setup will be a milling setup.
01:18
And I use this as a start point.
01:22
I use my stock that came from nesting as my stock for the setup.
01:33
I'll make my stock invisible for now so that allows for easier picking.
01:41
So at this point, I'm in a milling setup, so I can do traditional milling operations.
01:48
So for instance, I could do a drill operation with a drill that I've set up in my personal library.
01:58
This is one of the holes.
01:59
I also make it select all same diameter holes.
02:07
I see that the hole is not going really through the part.
02:12
So I add a negative offset at the bottom of the part.
02:22
That's my first milling operation.
02:26
The next milling operation would be to carve out the step or the groove.
02:32
So, I create a 2D pocket operation and I use a flat mill tool here for my library.
02:45
Geometry I want to mill out this portion here.
02:52
I want to limit that milling to just that face so that I'm not cutting into neighboring parts.
03:01
I also want to remove the stock to leave.
03:06
I don't need this because my tool is small enough to handle that detail.
03:12
And here is my pocket operation.
03:16
I use a similar operation for the groove so I can duplicate my first pocket operation and then change the geometry in my second operation.
03:27
So I can select as pocket here and my stock that limits the pocket,
03:41
oh, I missed that pick.
03:48
So now I have a drill, a pocket, and another pocket.
03:55
Those two pocket operation are just on one of the instances.
03:59
So if I want to create that on all the parts, it's very easy to create a component pattern.
04:09
And there you go.
04:11
So now let's have a look at the bottom side of the part.
04:17
You see, it has a curved nature and which we also want to cut out.
04:25
So here again, we need another setup.
04:29
Let me first bring back my stock here.
04:34
So it requires a second setup with the Z flipped in this direction.
04:46
And my stock is my existing part.
04:56
For this card phase, I think a correct 3D milling operation would be a scallop operation.
05:04
So I'm using scallop here with a ball mill tool.
05:10
And geometry, I want to machine, is just limited to this face here.
05:25
This is the face I want to machine, not this one.
05:37
The scallop doesn't have a correct step over.
05:41
So I'll make it a little bit fine, finer like a 0.025 inch, to get less scallop height.
05:53
So here you go on one part.
05:56
Here again, we can put it in a pattern to machine all the parts.
06:11
So we now have the milling operations correctly set up.
06:18
The only thing that remains to be done is to actually cut out the parts.
06:23
So we use the exact same procedure.
06:26
We create a new setup, this time cutting operation
06:31
and we use same part and we activate the setup.
06:46
So the 2D profile command, let's say it's Plasma Cutter,
06:54
the geometry that we want to cut out is not as easy to find as we would think.
06:60
So, the first pick would give me this.
07:03
If I pick again and then I can extend my selection.
07:10
And this is the profile that I really want.
07:19
Here again, I have a 2D profile on one of the parts.
07:24
To get it on all of them, I just use a component pattern.
07:36
So now we have set up all the operations to do a simulation.
07:52
And I'll run through it slowly.
07:56
So you see the pocketing operations.
08:06
I mean, if I wrote it here, you'll see the scallop operation at the bottom.
08:15
And then finally, the cutting operation with a couple of collisions
08:30
due to the head hitting the part, but that can be easily solved.
08:37
So if you then look on top side here,
08:42
you see that I correctly have cut out the parts, in the full detail, after the nesting.
08:54
Thanks for watching.
