Simulating toolpath and machine

00:03

In this video, you’ll: apply concepts required to perform toolpath and machine simulation.

00:10

Open the file Toolpath Verification.f3d.

00:15

In the Manufacture workspace, from the Browser, under Setup1, select a toolpath to display it on the canvas.

00:26

Review each toolpath listed.

00:30

After toolpaths have been created, it is important to simulate the toolpaths

00:36

to ensure that all the stock material has been removed properly.

00:41

Click Setup1.

00:44

In the Toolbar, from the Actions panel, select Simulate.

00:50

The Simulate dialog displays.

00:53

In the Display tab, with Toolpath enabled, ensure Toolpath Mode is set to Tail.

01:03

Then, ensure Stock is enabled, with Colorization set to Material.

01:10

From the Simulation player controls, click Play.

01:15

The simulation plays through each toolpath assigned to the setup,

01:21

including the Facing operation, the Adaptive clearing, the series of 2D Contours, and the final Chamfer toolpath.

01:32

Once the simulation is finished, in the Browser, toggle OFF the visibility of Models.

01:40

The canvas updates to show only the machined stock.

01:45

Zoom into the part and examine the edges and faces.

01:51

Currently, the part looks as if there are no issues with it.

01:56

In the Simulate dialog, expand the Colorization drop-down and select Comparison.

02:04

The part updates with different colors.

02:07

Green indicates the finished part, blue indicates that there will be remaining stock

02:14

and that not enough material has been removed,

02:17

and red indicates that gouging will occur, and the areas where too much material has been removed.

02:24

Zoom and pan to review the part.

02:28

In the interior faces of the part, at the corners,

02:33

the tool is too large to get into the contours of the part, which will leave material behind.

02:40

Also, at the base of the part, some gouging occurs.

02:45

Try increasing the tolerance.

02:48

In the Simulate dialog, in the Stock group, in the Tolerance field, enter, .005.

02:58

With increased tolerance, more gouging is apparent along the Chamfer toolpath.

03:04

In this case, this is acceptable because the chamfer did not exist within the original model.

03:11

Close the Simulate dialog.

03:15

From the Browser, toggle the visibility of Models back ON.

03:21

Then, from the list of toolpaths, select 2D Contour2.

03:27

Notice that the toolpath is below the part.

03:31

Right-click the toolpath and, from the shortcut menu, select Edit.

03:37

Open the Passes tab.

03:41

Disable the Stock to Leave option, and then click OK.

03:46

The toolpath updates so that now, it passes over the material and not under it.

03:53

From the Browser, select Setup1 and run another simulation.

03:60

From the Simulation player controls, press Play.

04:04

In the Simulation player, you can use the slider to adjust the speed of the playback.

04:11

Once the simulation is finished, notice that the red colorization is gone.

04:18

Save the file.

04:20

Verifying toolpaths using simulation is an effective way to ensure the appropriate amount of material is being removed

04:28

while your part is being machined.
