In this solution video for practice exercise 1, you’ll: plan the order of operation,

00:07

perform stock prep, design the fixturing method, ensure collision avoidance,

00:13

and evaluate cutting forces, optimize operations, and perform CAM setup for multi-axis fixturing.

00:21

Open the file Plan and Setup Work.f3d in the Manufacture workspace.

00:28

This part needs to be manufactured using a 5-axis vertical machining center.

00:34

Review the features of the part to begin determining how it can be machined.

00:39

From the ViewCube, select Top.

00:43

Most of the part can be machined from the topside, while secondary features can be machined from the side.

00:51

Now, determine how to hold the part.

00:55

From the Browser, expand Models > CAM Root:1.

01:02

Then, toggle ON the visibility of the dovetail holder and spacer.

01:07

Notice that the part is larger than the dovetail holder, which grants access to all sides of the machine.

01:15

Now, from the ViewCube, select Front.

01:20

You can see that the part is resting directly on top of the dovetail holder.

01:25

The dovetail can be cut at the same time as the floor of the part is finished.

01:31

Next, create a CAM setup.

01:35

From the Toolbar, Setup panel, select Setup.

01:40

The Setup dialog opens and stock displays in the canvas, encompassing the entire assembly, including the workholding.

01:50

To mitigate this, from the Setup dialog, under Model, click the Model selection prompt.

01:58

Then, in the canvas, pick the body of the part.

02:03

The stock updates.

02:05

Next, orient the work coordinate system.

02:09

In the canvas, pick the stem of the X-axis arrow.

02:14

Then, pick a face that the X-axis will be perpendicular to.

02:20

The work coordinate system is now properly oriented.

02:25

Back in the dialog, open the Stock tab.

02:29

Expand the Mode drop-down and select Fixed size box.

02:35

Then, in the Round Up to Nearest field, enter 0.

02:41

Now, update the size of the stock.

02:45

In the Width (X) field, enter 6.

02:48

In the Depth (Y) field, enter 2.

02:52

Finally, in the Height (Z) field, enter 1.75.

02:58

Review the size of the stock from the right side.

03:02

The stock is evenly distributed around the part.

03:05

For this part, it is ideal that all stock is above the part, with no stock remaining below it.

03:12

In the dialog, expand Model Position and select Offset from Bottom (-Z)

03:20

and then, in the Offset field, enter 0.

03:25

Open the Post Process tab.

03:28

Under Machine WCS, in the WCS Offset field, enter 1.

03:34

Before completing the setup, ensure the work coordinate system is positioned where you want it.

03:42

You can either choose to leave the WCS on the stock, or you can position it on a 0 point on the fixture.

03:51

For now, leave it on the stock.

03:55

Click OK.

03:57

Save the file.
