Swarf toolpath in Fusion

00:03

When using a swarf strategy in Fusion 360, it is helpful to have closed contours to select for the toolpath.

00:11

If your part does not have closed contours where you wish to swarf,

00:15

you can create a sketch for the toolpath to use.

00:18

To begin, with a part to be machined open in the Design workspace, expand Create.

00:24

Select Create Sketch.

00:27

Select the appropriate axis for the sketch and expand Create again.

00:32

This time, select Project / Include > Include 3D Geometry.

00:38

Zoom into the part and select edges to include in the new sketch.

00:44

These edges will act as the base of the swarf toolpath.

00:49

It might be helpful to toggle off the visibility of the model after selecting edges to ensure you have a closed sketch.

00:57

If necessary, use a line sketch to close the sketch.

01:03

Once the sketch is finished, navigate to the Manufacture workspace.

01:10

From the Milling contextual tab, expand MULTI-AXIS and select Swarf.

01:17

In the Swarf dialog, open the Geometry tab.

01:21

Ensure Drive Mode is set to Contours and set Selection Mode to Contour pairs.

01:27

This determines the direction the tool tip faces.

01:30

Select the sketch you just created and then select another contour directly above that sketch.

01:37

Back in the dialog, navigate to the Passes tab.

01:41

Enable Stock to Leave to specify the amount of material that must remain on the part after machining.

01:46

Set the Radial Stock to Leave to 0.

01:50

This is the amount to leave perpendicular to the tool axis, or on the walls of the part.

01:56

Set the Axial Stock to Leave to .01.

02:00

This is the amount to leave along the tool axis, or on the floors of the part.

02:06

Now, simulate the toolpath.

02:08

From the Actions panel, select Simulate.

02:12

Play the simulation and orbit the part to review the action of the swarf toolpath.
