In this lesson, we're going to create a rotary operation.
00:07
After completing this lesson, you'll be able to create a wrapped 2D operation and create a multi-axis rotary operation.
00:16
In Fusion 360, we're going to be taking a look at two new files, rotary wrap.F3D and rotary.F3D.
00:24
We're going to explore different types of fourth axis types of operations.
00:30
The first rotary wrap is going to take a look at using 2D operations, such as 2D adaptive clearing, 2D pocket and 2D contour,
00:40
and unwrapping and rewrapping those to a revolved part.
00:46
There are some limitations to the wrapped functionality.
00:49
It must be a truly cylindrical part.
00:52
It can't be tapered, and it has to be a true cylinder.
00:56
But what we're going to do is we're going to take a look at using 2D adaptive clearing to clear out this wrapped pocket.
01:04
We're going to start by selecting our tool and in our multi-axis tool library, we want to use our quarter inch flat end mill with aluminium roughing.
01:12
Inside of our geometry section.
01:14
The first thing that we're going to do is use the wrap toolpath option.
01:19
I'm going to select the outside of the cylinder, so that it knows that it has a two inch diameter.
01:24
This is important for it to unwrap and rewrap the toolpath.
01:29
The next thing that we need to do is select the pocket.
01:32
This is going to be the base or the root of that wrapped pocket.
01:36
I'm going to zoom out, so we can see exactly what happens when it starts to calculate.
01:41
For our passes, I'm going to turn off stock to leave but use all the other default settings and say ‘okay’.
01:48
As soon as it starts to create this operation,
01:51
you can see that it's creating a 2D adaptive based on a flat part and then rewrapping it around a cylinder.
01:59
If we take a look at this in simulation and we manually drag it over,
02:03
you can see that it's using that adaptive operation and it's rotating around the part.
02:08
Now again, this is not truly how it's going to work on a machine.
02:12
The adaptive motion is going to be moving in X, Y and Z.
02:16
However, the part itself is going to be rotating about the A axis.
02:21
So it's extremely important again that the coordinate system is set up in the appropriate manner,
02:27
so that the X axis is the rotation axis and Z is pointing up at the spindle of the machine.
02:35
Let's go ahead and save our rotary wrap, and we want to move onto our rotary toolpath.
02:41
Rotary is a true multi-axis toolpath.
02:45
You'll notice that it has this small icon on it meaning that it's an extension.
02:50
An extension must be purchased.
02:53
So in order to do this, you have to purchase an extension option.
02:57
I'm going to take a look at the machining extension, and I'm going to be using the purchase one day option, which is 25 cloud credits.
03:06
In order to do this, we get access to a whole host of different strategies.
03:10
We have steep and shallow, we have five axis and collision avoidance,
03:15
and we have many other things that are extremely helpful to multi-axis machining.
03:20
But once again, this is a purchase option meaning you'll need to purchase the extension.
03:25
Often times with these extensions, the first time you access them, there'll be some sort of trial period and you can play around with all the options.
03:34
For our purposes, I am going to use that multi-axis rotary but again, you don't have to purchase it.
03:40
You can see how it works here and see if it's useful to you.
03:44
We're going to select a tool and in this case, I'm going to be using my half inch flat.
03:49
So I'm going to select my half inch flat end mill tool number 7 and aluminium roughing.
03:55
In the geometry section, this is important because we need to set up the rotation or the rotary axis.
04:02
In here, we want to make sure that the rotary axis isn't based on our WCS setting.
04:09
Again in this case, we need to make sure that it's revolving around the X axis, so we can set up our X axis.
04:16
So you can see here that it's now using the X or the revolved axis.
04:21
And also note that we do have some angular limit options that we're not going to be exploring here,
04:26
but we can dictate whether or not we wanted to start and end in a certain orientation.
04:31
Because this is a rotary or revolved type operation.
04:36
The stock settings look more like they do in a turning operation, and we're going to leave them as default.
04:41
But these will dictate things like our clearance are retract and are outer radius.
04:47
For our passes, there are a couple things that we need to dictate.
04:50
Our rotary passes are based on a spiral based on a linear or a line view or a circular.
04:59
If we do a spiral, it's going to be going around the part as if it's a thread.
05:05
If we go back in and we take a look at our line option, it's going to go back and forth along the X axis as it's removing that material.
05:15
And you can see that this gives us a pretty close representation of the geometry.
05:21
And that third option that we have in the past is section.
05:25
Using a circular, we will allow it to go around and then step over in the X direction as it makes its passes.
05:32
So this is not going to give us the cleanest option for this geometry.
05:37
In our case, using the line option is going to give us the best representation of her geometry.
05:44
You could also use a rounded tool, like a ball end mill to get much closer to the final shape.
05:49
You can see even in this case, the flat end mill gives us a pretty good result.
05:54
Let's take a look at this and simulate, so we can get a better idea as to how the tool is moving.
05:59
So you can see that the tool is moving in X and Z simultaneously, and then it's rotating the part about the A axis as it does this again.
06:10
So in a situation like this, this specific toolpath with how we're using it to cut is only moving in X and Z.
06:17
And then it's rotating about the A axis to its next position.
06:21
If we were to use the spiral option, it would be moving in X and Z while it's constantly rotating about the A axis.
06:31
So we have to keep in mind again, the orientation of our X , Y and Z and how critical that is to our fourth axis positioning.
06:39
Once again, this is an extension option.
06:42
And if you want to learn more about the extensions, you can always go into your preferences,
06:47
into preview features and you can go to your workspace manufacturer and just look at what's available with the extension add-on.
06:57
There are advanced arranged, we've got live machine data connection restrict to full axis, split a toolpath and change tool modifications.
07:06
These are things like trim toolpath and delete.
07:10
And all of these options come available to you when you purchase the machining extension.
07:16
You can also come in here and take a look at each of these.
07:20
And there's also a fusion 360 extension’s link that tells you more about each of them.
07:25
For right now, let's make sure that we've saved rotary and rotary wrap.
07:29
And if you haven't purchased the extension to play around with rotary,
07:32
you can also explore some other options that you have and try to machine this geometry with some of the existing toolpaths.
07:39
Once you've saved these, let's go ahead and move on to the next lesson.
