In this lesson, we will create a 3+2 pocketing toolpath.
00:07
After completing this lesson, you'll be able to create a multi-axis position contour toolpath,
00:12
simulate toolpaths to validate motion and create a duplicate toolpath and modify its parameters.
00:20
In Fusion 360, we will carry on with our multi-axis positioning design.
00:24
If you had any difficulty, you can also upload the supply data set, multi-axis positioning V9.
00:31
At this point, let's take a look at what's been done.
00:33
So we understand what has to happen next.
00:36
We've done a roughing operation as well as outside profile, taking care of the top pocket, then drilling and tapping the top four holes.
00:46
We then moved on to some multi-axis positioning operations to spot and drill the four large holes on each arm.
00:54
At this point, we want to take care of the counter bores on each of those positions.
00:60
In order to do this, we will need to do another 3+2.
01:04
But in this case instead of drilling, we're going to be using a 2D contour.
01:08
The reason that a 2D contour works in this case is because we've already predrilled these holes.
01:13
So that way we have an entry position in the center,
01:16
it will be much easier for us to come in with a 2D contour or another circular operation such as a bore.
01:23
But in this case, we will select 2D contour, and we want to use tool number six, which is a 3/8th flat.
01:30
We've already used this tool before, so it should already be in our documents.
01:36
Once we select the tool, we will go to our geometry, and we need to select our tool orientation.
01:42
Once again, we need to select the Z axis,
01:44
and this can be done by selecting either a face we want Z to be normal to or by selecting a cylindrical face, and it will align its axis.
01:53
After we make that selection, we can see that Z is in the correct orientation.
01:58
At this point, we now need to select our contour.
02:01
We're going to be creating a 2D contour at the bottom, and you can see that we have the arrow on the appropriate side already.
02:10
In the heights section, it's automatically and go based off that selected contour.
02:15
So in the past this section, we simply want to make sure that we're not doing any roughing or multiple depths.
02:20
We're going to move on to our linking parameters, and we'll leave everything as default for now and simply say ‘okay’.
02:28
Once the operation is created, we can see a preview on the screen but before we go ahead and create duplicates,
02:35
let's take a look at what is actually being machined with that operation.
02:40
So the tool comes in, you can see that it plunges, and then it creates that pattern.
02:46
We're going to go back to the previous operation and play through again.
02:50
But this time I want to slow it down a little bit.
02:52
I want to see how it engages the stock to see if we need to add a roughing pass.
02:58
As it goes in, it's actually machining, which tells me that it's removing too much material in this single pass.
03:07
There are a couple different ways that we can handle this.
03:10
We can add a secondary pass or a roughing pass or inside of our linking parameters,
03:16
we can either have it ramped down or give it a predrill entry position.
03:21
In this case, I'm going to select the predrill position being the center and say ‘okay’, allow it to regenerate and then simulate it one more time.
03:31
What we should see now when we simulate is that the tool is going to be entering at the center of the hole,
03:37
and then moving its way around and making the cut.
03:41
However, with that predrill position, we now have a warning with our toolpath.
03:45
It says it cannot use drill positions because keep tool down is not activated.
03:51
So we need to check that setting inside of our linking parameters for keeping the tool down.
03:57
If we use keep tool down and we say ‘okay’, we should allow it to regenerate and no longer have that warning.
04:04
We will simulate one last time before we create any duplications just to make sure that everything is working properly.
04:11
Everything looks good, and now that we have a handle on the operation, we can duplicate it and take care of some of the other geometry.
04:18
I'm going to rotate the body around, and then I'll duplicate my 2D contour, I’m going to right click,
04:24
and I'm going to select duplicate and then the new duplicate will right click and edit.
04:30
Remember we first need to change the tool orientation, so I'm going to reselect a Z face.
04:36
Then I need to reselect the chain I want a machine,
04:41
because we've also gone in and given it a predrill position, we will have to come back and make sure we select that as well.
04:48
Once we have all these settings, we can say ‘okay’ and allow it to create this new operation.
04:53
So you can see we've taken care of the two counter bores,
04:56
but we're not ready to quite pattern these yet because we have to machine a little bit more geometry.
05:01
Before we do that, let's go back to our Home view and save the design before moving on to the next step.
