In this video, we'll create a Lathe groove toolpath.
00:06
After completing this step, you'll be able to create a groove toolpath and edit a tool.
00:12
In fusion 360, we want to carry on with our CAD CAM Lathe dataset.
00:16
The next thing we want to do is create a single groove toolpath.
00:20
So we're going to select turning in single groove.
00:24
We need to select an appropriate grooving tool so we'll go into our Lathe library and we're going to select OD grooving.
00:32
We'll select and then we need to make our geometry selection.
00:35
But let's note our feeds and speeds and note that we are using constant surface speed
00:40
because we're going to be entering the stock and the radius value is going to be changing,
00:45
using constant surface speed we'll adjust the rpm based on our values.
00:50
Next, we want to select our geometry.
00:52
I'm going to select this back edge but let's note the tool preview.
00:57
You can see that the tool is actually cutting away more than intended because the alignment right now is set to middle.
01:03
If we said it to back, notice that it goes to the back side of that contour.
01:08
If we set it to the front, then our tool is on the correct portion.
01:12
Notice that we also have the groove alignment tip and cut through.
01:17
We're going to use a tip alignment and we're going to leave all the other settings as is and say okay.
01:23
The tool comes in and cuts the groove. However, our tool actually has a radius corner.
01:29
So when we look we're not getting a clean cut through the groove because this is just a recess for us to thread, it's probably fine as is.
01:37
But let's go ahead and make a change to our tool.
01:40
We're going to expand the toolpath, right click on the tool and select "Edit tool".
01:46
Inside of here our insert is defined in millimeters as a square end and you'll notice as we go down.
01:52
The thickness value is three, the width is 2.2 and it has a corner radius of .8.
01:58
Our groove is actually 2.75 mm and we don't want the corner radius.
02:03
So we're going to set this to 0 which will be a custom value. And we're going to say 0.
02:09
Now we have a perfectly square grooving tool that's the exact width of our groove, but we need to go ahead and regenerate our single group.
02:17
We'll go up to actions and select "Generate".
02:20
Now the tool goes in and we no longer have the radius corner. It cuts everything as expected.
02:26
At this point, you can see that the outside of our part is matching the design intent.
02:31
We've created our roughing and finishing toolpaths as well as our grooving toolpath for the entire outside of our part.
02:37
Let's go ahead and navigate back to home view, and let's make sure that we save the design before moving on.
