Preparing threading toolpaths

00:08

Fusion contains functionality specific to toolpaths that involve threading.

00:15

Using the Threading tool, you can easily and efficiently place both internal and external threads on a part.

00:23

In the exercise file, a setup has already been created.

00:28

For this video, open the file Turning Threading.f3d.

00:34

Notice that a setup has already been created.

00:37

The part has been faced, rough profiled, finish profiled, and a hole has been drilled.

00:45

Now, it is time to place internal threads and external threads on the hole.

00:51

To place the external threads, in the Browser, ensure that Setup1 is selected.

00:58

On the Toolbar, Manufacture workspace, Turning tab, Turning panel,

01:05

expand the Turning drop-down and select Turning Thread.

01:12

A dialog opens for Thread1.

01:15

In the Tool tab, under Tool, click the Tool selection prompt.

01:21

The Select Tool browser opens to a document folder titled, “Turning Threading”.

01:28

Select OD Threading, and then click Select.

01:32

Back in the Thread1 dialog, open the Geometry tab.

01:37

In the canvas, select the portion of the model that you want to thread.

01:42

In this case, click the threaded cylinder face.

01:47

In the dialog, the selection tool changes to Face.

01:52

Open the Passes tab.

01:54

In the Thread Depth field, type “.0589”.

02:01

In the Number of Stepdowns field, type “4”.

02:06

In the Thread Pitch field, type “.166”,

02:11

or you could type “1/6” to have Fusion calculate the thread pitch for you.

02:17

Click OK.

02:20

Now, it is time to simulate the threading operation.

02:24

In the Browser, select Setup1, and, on the Toolbar, in the Actions panel, click Simulate.

02:33

The Simulate dialog opens.

02:36

Under Stock, enable the checkbox next to Stop on collision.

02:42

On the Simulation Player, click Play.

02:46

When the simulation reaches the threading operation,

02:49

notice that the tool stops because it collides with the back wall of the part.

02:54

To adjust this, in the Browser, right-click Thread1, and, from the shortcut menu, select Edit.

03:03

The Thread dialog opens.

03:06

Open the Geometry tab, and under Confinement,

03:10

in the Backside Stock Offset field, type “-.05”.

03:17

Click OK.

03:19

With the setup selected, from the Toolbar, simulate the setup again.

03:25

This time, when the simulation reaches the threading toolpath,

03:29

the Threading tool completes the operation with no collisions detected.

03:35

In the Simulate dialog, click Close.

03:40

Next, you need to place the internal thread.

03:43

Pan and zoom the part to see the inside of the hole more clearly.

03:49

From the Toolbar, expand the Turning drop-down and select Turning Thread.

03:56

A dialog opens for Thread2.

03:59

Click the Tool selection prompt, and, in the Browser, this time select 15 – Internal Threading.

04:08

Click Select.

04:11

Back in the dialog, under Mode & Direction,

04:15

expand the Turning Mode drop-down and select Inside threading.

04:21

Open the Geometry tab.

04:23

In the canvas, click the face inside the hole.

04:28

In the dialog, the selection tool changes to Face.

04:33

Open the Passes tab.

04:36

Under Passes, change the Thread Depth to “.05”,

04:41

the Number of Stepdowns to “4”, and the Thread Pitch to “.1”, or 1/10.

04:50

Open the Geometry tab again.

04:53

Since you know that you want to stop the threads a little short,

04:56

under Confinement, in the Backside Stock Offset, type “-.05”.

05:04

Click OK.

05:06

In the Browser, select Setup1.

05:10

From the Toolbar, simulate the setup again.

05:14

This time, the simulation animates the internal threading operation as well.
