Adjusting toolpath settings

00:08

You can use the Simulate tool to determine solutions for toolpath issues identified during a simulation.

00:17

For instance, you can use the Simulate tool to see how a stock will look when the part is finished.

00:23

For this video, open the file Turning Simulation Adjustment.f3d.

00:30

Here, a setup has already been provided, along with all the toolpaths needed to create the current part.

00:38

In the Browser, turn off the visibility for the part that you are simulating.

00:43

In this case, that means expanding Models > CAM Root:1,

00:48

and turning off the visibility for Steering Quick Release v1:1.

00:54

Now, select Setup1.

00:58

Then, on the Toolbar, Manufacture workspace, Turning tab, Actions panel, click Simulate.

01:08

The Simulate dialog displays.

01:11

Verify that, under Toolpath, the Mode is set to Tail.

01:17

Under Stock, verify that the Mode is set to Standard,

01:21

and that the Colorization is set to Comparison.

01:26

In the canvas, on the Simulation Player, click Play.

01:31

When the simulation arrives at the profile operation,

01:34

notice that the tool takes a very light cut.

01:39

You now know that you need to step the cut down.

01:43

In the Simulate dialog, click Close.

01:47

In the Browser, under Setup1, right-click Profile Roughing1,

01:52

and, in the shortcut menu, click Edit.

01:57

A dialog opens for Profile Roughing.

02:01

Open the Passes tab.

02:04

Under Passes, in the Maximum Depth of Cut field, type “.15” for 150/1000 of an inch.

02:13

Then, enable the checkbox next to Even Depths of Cut,

02:18

so that you do not have too light or too heavy a cut on the way down.

02:24

Also, enable the checkbox next to Use Pecking so that the tool with take multiple plunge cuts.

02:32

Now, the cuts will be broken up, which works well for stringier materials.

02:38

Now, before simulating the change, you must regenerate the grooving operation,

02:44

since it is a rest machining operation.

02:48

In the Browser, under Setup1, right-click Groove1,

02:52

and, in the shortcut menu, click Generate.

02:56

When the regeneration is complete, in the Browser, click Setup1.

03:02

Again, from the toolbar, click Simulate to simulate the whole setup.

03:08

On the Simulation Player, click Play.

03:12

Now, the simulation shows the desired results, but it also shows that the first cut is too deep.

03:19

On the Simulation Player, use the feedrate slider to slow down the animation,

03:24

and then click Go to previous move to reverse the last toolpath.

03:30

Now you can see that, because of your adjustments,

03:33

it is simulating the chip-breaking action that you are looking for.

03:37

You still need to go back and make a small adjustment to the cut,

03:41

but by using the simulation, you can see that you have increased the depth of the cut,

03:47

and that you have added the pecking cycle to the profiling roughing operation.
