Practice exercise

00:00

Open the drawing file Turning Practice.pdf, which accompanies a 3D model that is to be machined on a lathe.

00:13

When reviewing a drawing, you must look for critical dimensions,

00:17

such as the length, height, and diameter of the part, as well as any notes indicating variations in the dimensions.

00:27

Interpreting both the dimensions and any special instructions before machining allows you to recognize workholding requirements.

00:36

You can then prepare the model and choose the appropriate tools for the tool library.

00:43

In this example, notice that the flanges feature tolerances that need to be included when planning the machining of the part,

00:51

as well as length tolerances.

00:54

The tolerances listed indicate that the part needs to be machined at once, instead of being turned at different intervals.

01:02

Now, notice that the note on the drawing reads, “Break all flange edges.”

01:09

The flange edges could be chamfered using the Design workspace in Fusion, or you can add a chamfer toolpath to break the edges.

01:19

Next, review the threaded face of the part.

01:23

The threaded face has been modeled, making the threads difficult to select when working in the Manufacture workspace in Fusion.

01:31

To rectify this, you can delete the modeled threads and, instead, use cosmetic threads that will be cleared out using a toolpath.

01:42

Now, open the file in Fusion.

01:45

While in the Design workspace, select the faces of the threads of the part and delete them.

01:53

As soon as you do, the cylindrical face heals.

01:57

In addition, you could add chamfers to the flange edges using Modify > Chamfer, or you can create a toolpath to chamfer the edges.

02:09

Either method would work to remove sharp edges from the model when it is tooled.

02:15

Next, it is time to configure the tool library.

02:20

Expand the Workspace picker and select Manufacture.

02:25

From the toolbar, expand the Manage drop-down and then select Tool Library.

02:33

The Tool Library displays.

02:36

With Cloud library enabled, create a tool library.

02:41

From the library list, right-click Cloud and then select New library.

02:48

A text field displays.

02:51

Enter a name for the library, such as, “Practice”.

02:56

From your keyboard, press ENTER.

02:59

Now, from the Fusion 360 Library, select Turning – Sample Tools.

03:06

The Turning Sample Tool library displays.

03:10

Select the tools from the library you will need to use to machine the part, such as grooving tools, boring bar tools,

03:19

threading tools, and finishing tools.

03:23

Once they are all selected, right-click and select Copy tools from the shortcut menu.

03:30

Now, return to the Practice library.

03:34

Right-click and select Paste tools.

03:38

As of right now, none of the tools are numbered.

03:43

To number the tools, from the toolbar, select Renumber tools.

03:48

The Renumber tools dialog displays.

03:51

Ensure that both the Start from and Increment by values are correct, and then click Renumber.

04:01

Now, the tools have been assigned numbers in the Practice library.

04:05

Close the library.

04:08

After reviewing and interpreting the drawing, making design changes to the model,

04:14

and configuring a library, you are now ready to begin applying toolpaths to the part.
