Create a facing toolpath

00:02

In this video, we create a facing toolpath.

00:06

After completing this step, you'll be able to create a facing toolpath and modify toolpath parameters.

00:13

In fusion 360, we want to carry on with our gear housing for CNC mill.

00:18

Now that we've created are set up, we're going to create our first toolpath which is going to be a facing operation.

00:24

Typically you do a two D face operation to clear the top side of the part to make sure that you have a nice plane or face.

00:31

We're going to start by selecting our tool,

00:33

and we can do this by going into our cam DFM library and taking a look at tool number eight are 2 inch face mill.

00:40

Note that there's only a single default presets,

00:43

so we don't have to worry about selecting the correct one but we always want to validate our feeds and speeds.

00:49

Next in the geometry section, fusion 360 automatically knows where the stock boundary is based on this yellow box,

00:56

it knows how much material there is and if we navigate to the heights section it knows that it's starting at the top of the stock,

01:03

and its machining down to the top of the model so we don't have to adjust any settings there either.

01:09

In the past is section we can make adjustments for things like the past direction.

01:14

the extension, which is how much we wanted to overlap the outside of our part.

01:18

If we have any additional offset values.

01:21

If we want to modify the step over amount which is based on the tool diameter and if we wanted to cut both ways or just a single direction.

01:29

We also have some other options, for example use chip thinning,

01:32

which changes the way that it reduces the chip load as it's entering the cutting edge.

01:38

If we have a lot of stock on the top of apart and we have a tool that can only take away a small cut, we might want to use multiple depths.

01:45

In this case, just a single pass will do.

01:48

We use the default linking parameters but note that we have several that are kept on by default such as allow rapid retract and keep tool down.

01:56

We're going to leave all these as default and say okay allowing it to create our toolpath.

02:01

Notice on my screen that I have a stock preview of what's been done.

02:05

If you don't see a stock preview, make sure to go to utilities and turn on your automatic in process stock generation,

02:12

and in the bottom center section of your canvas area you can display the in process stock.

02:17

Once we've created our first toolpath, let's go ahead and save the design before moving on to the next step.
