In this video, you’ll :

00:07

Analyze the supplied drawing and/or model and select the appropriate manufacturing process.

00:14

When reviewing a model to determine the appropriate manufacturing process,

00:19

it is often the case that more than one process may be required to manufacture it in the most efficient way possible.

00:28

Open the file Stock Selection.f3d.

00:32

This part could be milled, but because it is circular, it would be more efficient to lathe it first.

00:40

So, the first step in preparing this model for both the lathe and milling processes is to copy it to create a lathe model.

00:48

The lathe model will then be used in the setup for the milling process for this part.

00:55

In the Design workspace, from the Browser, expand Bodies and then select Body1.

01:02

Right-click Body1 and, from the shortcut menu, select Copy.

01:08

Then, right-click the Bodies folder and select Paste to paste it into the same location as the original part.

01:17

The Move/Copy dialog displays, but do not make any changes.

01:22

Simply click OK to close the dialog.

01:26

Back in the Browser, toggle OFF the visibility of Body1.

01:31

Select Body2.

01:33

Click twice slowly on the name to activate the text field.

01:39

Enter “Lathe” to rename it.

01:42

Now, to create the lathe stock body, you can delete the features that would be milled from the Lathe body.

01:51

Select the holes at the end of the fingers and then, from your keyboard, press DELETE.

01:59

Continue to select holes in the model and delete them.

02:03

There are other ways to select features.

02:06

From the Toolbar, in the Solid tab, expand the Select drop-down.

02:12

From here, click Freeform Selection.

02:16

Now, in the canvas, click and drag your cursor clockwise to create a freeform, closed shape with a solid line as its boundary.

02:27

This is an inclusion selection that selects only objects within the boundary.

02:33

Now, click and drag your cursor counterclockwise.

02:37

A freeform shape displays, with a dotted line as its boundary.

02:42

This is a crossing selection, and it selects all objects within the boundary, even if those objects extend past the dotted line.

02:53

Click and drag your cursor clockwise to create an inclusion selection of one of the pockets at the edge of the part.

03:02

From your keyboard, press DELETE.

03:05

The pocket is deleted.

03:07

Delete all the pockets using this process.

03:11

This is an efficient way to delete areas of a model.

03:15

Now, continue to select any sloping faces of the model and delete them.

03:21

Press CTRL as you select the adjacent faces, and then press DELETE.

03:27

The program automatically heals the model into a solid form.

03:36

Next, select the mating faces of the fingers and delete those.

03:44

Again, the model heals itself.

03:47

Once you have finished healing all the holes and faces, the part appears as it will be after it is lathed.

03:56

Now it is time to set this body as the starting stock for the milling process.

04:04

First, toggle OFF the visibility for the Lathe body, and then select Body1 to make it active.

04:12

Expand the Workspace picker and select Manufacture.

04:17

In the Milling tab, select Setup.

04:21

The Setup dialog for this part displays.

04:24

On the Setup tab, leave the Work Coordinate System (WCS) as it is.

04:31

Open the Stock tab.

04:34

Expand the Mode drop-down and select From solid.

04:39

Now, from the Browser, under Models, navigate to Bodies and select Lathe to designate the lathe model

04:47

as the stock that the milling process will begin from.

04:51

Save the file.

04:53

Now, the model is prepared to be lathed and milled.
