In this video, we'll discuss Lathe part model prep.
00:07
After completing this step, you'll be able to use direct modeling tools and remove external threads.
00:14
In Fusion 360, we want to carry on with our CAD/CAM Lathe dataset 1.
00:19
We're going to navigate back to the design workspace and we want to take a look at the design that we have and make some adjustments for manufacturer.
00:26
I want to know that this specific design is using Fusion 360 for its creation,
00:32
we modeled the entire part which means that we have our chamfers and our threads all contained in our timeline.
00:39
But if we were dealing with an imported model that didn't contain that information,
00:43
we can still use some of our direct modeling tools to remove or adjust features.
00:48
In order to do this, let's make a quick edit to the external thread by right clicking and editing the feature.
00:55
We're going to change this to a model threat and select "OK".
00:59
I also want to know when we do that, how it produces problems in the rest of the model.
01:04
Our front chamfer is not as intended.
01:07
Now the chamfer on this model is so that we have a lead in for our threading tool.
01:11
But once we change the threads to a model thread we now no longer have that nice crisp edge where the chamfer was applied.
01:19
Let's look at ways in which we can deal with models that have physical threads and perhaps some other features that we might want to modify.
01:26
First, what I'm going to do is, I want to select the chamfers on the inside and outside on these two edges go to modify and select "Delete".
01:36
Fusion 360 automatically will remove and patch the geometry for us.
01:41
Notice that we have something in the timeline called Delete face.
01:45
This can also work for removing physical threats.
01:49
It's important to note that there are many different ways which we can remove threads. One of them is to create an extrude.
01:54
However, in this instance what we're going to do is select the thread faces. Go to modify and select "Delete".
02:02
Now Fusion 360 automatically removes that
02:05
but we want to make sure that we understand the outside diameter is going to be the same as what it was originally for the threaded feature.
02:14
So we need to make sure that we identify this because a detailed drawing might simply show an M50 thread and not a diameter of 49.703.
02:24
Now that we have this diameter back. We can also select that chamfer and hit delete.
02:30
Making sure that we don't have physical threads on the model
02:33
and in some cases chamfers means that our selection process is easier and we can go back and to find those later.
02:39
So at this point we've removed the external thread but she'll know that it doesn't have the physical threads,
02:46
it doesn't have the model threads or even the appearance of threads.
02:50
So we need to still reference are detailed drawing to better identify and understand what this geometry is.
02:56
Let's navigate back to the manufacturer workspace and note that the changes that we made to the model have now affected our set up.
03:04
Let's right click and edit the setup, noting that the operation has missing references.
03:09
So we're going to clear those and we're going to make some new selections.
03:13
If we need to manually select our Z rotation axis,
03:17
we can select a cylindrical face and once we make that selection, everything comes back.
03:22
Fusion 360 had automatically done this for us the first time.
03:25
But after we made changes to our geometry,
03:28
such as removing chamfers and fillets or removing those physical threads, we now have to make our selections again.
03:35
Let's double check the rest of our settings to make sure that our stock is still defined as we intended and all the rest of the settings look okay.
03:42
So I'm going to select "OK". Go back to home view and make sure that I saved before moving on.
