Specifying the model, chuck, and safe Z

00:10

A setup specifies what you want to machine and how.

00:14

A setup is the first thing you create in the Manufacture workspace,

00:18

and it is used to contain manufacturing operations.

00:23

For this video, open the file Lathe CAM Setup.f3d.

00:30

In this example, you want to apply a CAM setup to apply lathe toolpaths.

00:38

On the Toolbar, change the workspace from Design to Manufacture.

00:43

In the Manufacture workspace, there is a Home View

00:46

already set up for the part so that you can look at it more appropriately.

00:52

Now this view is active, you must define the work coordinate system and the stock.

00:59

On the Toolbar, in the Manufacture workspace, Milling tab, Setup panel, click Setup.

01:08

The Setup operation dialog opens to SETUP1.

01:12

By default, in the Setup tab, under Setup, the Operation Type is set to Milling.

01:22

For this example, expand the drop-down and select Turning or mill/turn.

01:29

Now, in the canvas, Fusion finds the center of axis rotation.

01:35

To change the direction of the Work Coordinate System, in the Setup operation dialog,

01:41

under Work Coordinate System (WCS), select the checkbox next to Flip Z Axis.

01:50

In the canvas, the Z axis flips to the front.

01:55

To change the orientation of the X axis, in the canvas, select the X axis arrowhead.

02:03

Alternatively, in the Setup operation dialog, you could select the checkbox next to Flip X Axis.

02:12

Also in the Setup operation dialog, you can configure your Safe Z.

02:18

Expand the Safe Z Reference drop-down.

02:22

Here, you can reference three points: the work coordinate system origin, the Stock front, and the Stock back.

02:33

For this example, leave the reference set to Stock front.

02:39

In the Offset field, type “.5” to change the safe offset to be in front of the stock.

02:48

To specify which model you want to machine, under Model, next to Model,

02:54

click the selection tool, and then, in the canvas, select the part that you want this setup to be applied to.

03:03

In this case, the selection indicates that a Body has been selected.

03:09

You can see that the stock is now applied to that part.

03:15

You can also specify where the chuck is located in the dialog.

03:20

Under Chuck, leave the Chuck reference drop-down set to Model back, but,

03:26

in the Offset field, type “-.5” to specify the amount of space to be offset.

03:34

In the canvas, you can see that this specification

03:37

puts the part inside the chuck, so you need to change the specification.

03:43

Back in the Offset field, type “-.4”, and in the canvas,

03:49

the part is brought to the front where the chuck is.

03:53

In this example, a chuck has been inserted into the model as a solid model,

03:59

but be aware that you do not actually need this chuck.

04:03

You can use the chuck reference in the Setup operation dialog to specify where the chuck starts.

04:11

In the dialog, open the Stock tab.

04:14

This is where you can see the setup for the existing stock.

04:19

Under Stock, in the Mode drop-down, notice that the stock is a Fixed size cylinder.

04:28

To change the outside diameter, in the Stock Diameter field, type “2.75”.

04:37

In the Length field, type “3.5”.

04:42

In the canvas, click Left on the ViewCube to look at the part from the side.

04:48

You can see that the stock is currently split,

04:51

and that half of it is in the front, and the other half is in the back.

04:58

Back in the Setup operation dialog, under Stock, expand the Model Position drop-down,

05:05

and click Offset from front to offset the stock from the front of the part.

05:12

In the Offset field, type “.05” to specify how much you would like to face off.

05:21

Now, when you use the ViewCube to look at the part from the side view,

05:26

you can see that most of the stock is held on in the chuck.

05:31

Move the view around to observe how some of the chuck is offset from the front of the part.
