Practice exercise

00:00

After adding toolpaths in order to machine a part, it is important to use the Simulation tool

00:10

to verify that these configurations yield the correct results.

00:15

Reviewing toolpaths using simulation helps to confirm stock removal procedures

00:20

and helps to determine which adjustments are required to ensure collision avoidance.

00:26

Open the file Turning Practice.f3d.

00:31

Simulate the entire setup.

00:34

The Simulate dialog displays.

00:37

Ensure that the Mode is set to Tail, and that the stock Colorization is set to Comparison.

00:45

Now, in the canvas, anything highlighted in blue indicates remaining stock,

00:51

anything in green indicates a finished part, and anything in red indicates a collision.

00:58

For a truly accurate simulation result, play it without the threaded adapter model.

01:05

In the Browser, turn OFF the visibility of Threaded Adapter:1.

01:11

Now, when you play the simulation, you will only see the stock results.

01:17

On the Simulation Player, click and drag the feedrate slider to speed up the simulation.

01:24

Then, click Play.

01:27

If you can verify that the toolpath is working correctly, click Go to next operation to skip to the next toolpath.

01:36

When the simulation reaches the Groove2 toolpath, in the Simulation timeline, notice that there is a red mark indicating a collision.

01:46

When the simulation reaches the Profile Roughing3 toolpath, there is another collision.

01:53

And in the Part1 toolpath, it indicates a third collision.

01:59

From the simulation, you now know that these toolpaths need to be adjusted to prevent collisions.

02:06

In the Simulate dialog, click Close.

02:10

On the Browser, under Models, next to the Threaded Adapter:1 model, turn the visibility back ON.

02:20

Under Setup1, edit the Groove2 toolpath.

02:25

In the dialog, on the Passes tab, note that the UpDown Direction is set to Up and down.

02:35

In the simulation, you can see that, when the toolpath goes across and reaches the finishing pass,

02:41

it goes up the walls when the collision occurs.

02:45

To correct this, set the UpDown Direction to Only down.

02:52

To verify that the collision has been corrected, simulate the toolpath again.

02:57

In the Browser, under Setup1, click the first operation, and, on the keyboard press and hold SHIFT, and select the grooving operation.

03:09

Then, from the Toolbar, click Simulate.

03:13

On the Simulation timeline, notice that all the red marks have disappeared.

03:19

In the Browser, select the grooving toolpath.

03:23

Turn off the visibility of the Threaded Adapter:1 model.

03:28

Play the simulation.

03:31

Adjust the feedrate slider to slow down the simulation.

03:35

Observe that, as the simulation animates the grooving toolpath this time, the collision is no longer there.

03:44

Close the Simulate dialog.

03:47

Turn the visibility of Threaded Adapter:1 back ON.

03:52

Simulate the parting toolpath to verify that it is working correctly.

03:58

Edit Part1 to open the Part1 dialog.

04:03

On the Radii tab, indicate the Inner Radius with a selection, and then in the canvas,

04:09

click the three-quarters-of-an-inch (Inner 3.75 in) hole in the middle of the part.

04:17

Open the Passes tab.

04:21

Enable the checkbox next to Allow rapid retract.

04:25

Then, click OK.

04:28

In the Browser, click Setup1 again, and then turn OFF the visibility of Threaded Adapter:1.

04:37

Simulate the toolpath again.

04:40

On the Simulation timeline, notice that the red collision mark near the parting toolpath has disappeared.

04:47

Play though the simulation to verify that the collision has been corrected.

04:53

Click Go to next operation to scan through all the operations until the simulation reaches the parting operation.

05:01

The only collision indicated is near the boring operation.

05:06

The radii or the tool can be changed later to correct for this collision.

05:12

Understand that, by using the simulation, you can verify that the configurations for the toolpaths are yielding the desired results.
