In this video, you’ll: •
00:06
Apply procedural concepts to review collisions for toolpath adjustments.
00:11
The Simulate tool can detect collisions in toolpaths
00:15
and can provide information to help you resolve them by making adjustments to the toolpaths.
00:22
Open the file Collision Adjustment.f3d.
00:26
Some basic toolpaths have already been applied.
00:30
There is a 3D adaptive toolpath that roughs up the material,
00:35
a 2D adaptive toolpath that cleans out one of the open pockets,
00:40
a 2D contour toolpath that cleans one of the fingers,
00:45
a 2D contour toolpath that cleans the inside,
00:49
and a single surfacing toolpath.
00:52
It is good practice to review toolpaths to make sure that there are no collisions.
00:57
In the Browser, click Setup1, and then, on the Toolbar,
01:02
Manufacture workspace, Milling tab, Actions panel, click Simulate.
01:08
In the Simulate dialog, in the Display tab, under Toolpath,
01:13
expand the Mode drop-down, and click Tail.
01:17
Under Stock, leave the Mode set to Standard
01:21
and the Colorization set to Comparison.
01:25
In the canvas, notice that there are some red marks along the Simulation player timeline.
01:31
These indicate collisions.
01:34
When you hover your cursor over each of these red marks, a tooltip displays a description of each collision.
01:42
In this case, the first collision is caused by the holder colliding with the stock.
01:48
On the Simulation Player, you can click Play and watch to see where the holder might be hitting the stock.
01:56
Alternatively, on the Simulation player timeline,
01:60
you can click a point ahead of the red mark so you do not have to wait for the simulation to arrive at the collision.
02:07
Click somewhere close to the first collision.
02:11
You can see that as the simulation moves through the collision,
02:15
the tool turns red in the moment when it collides.
02:20
You can also see the gray of the 3D model through the simulation.
02:25
That shows that when the STL file is removed for the stock,
02:30
you can see the gray underneath, which is another indication that there is a collision issue.
02:37
Now, on the Simulation player timeline, click a point close to the middle,
02:42
where the fifth red collision indicator is located.
02:46
In the canvas, this appears to be another 3D collision.
02:51
Click closer to the end of the timeline to view the last collision.
02:55
The collisions display in the canvas.
02:59
In this case, the tool is not long enough to make the contour around the outside of the part.
03:06
In the Simulation dialog, click Close.
03:10
Review the Scallop1 toolpath and observe that there are some collision issues there as well.
03:17
There are a few ways that you can adjust these toolpaths.
03:21
For the 3D adaptive toolpath, in the Browser, right-click Adaptive1 and select Edit Tool.
03:29
The Edit Tool dialog displays.
03:33
Open the Cutter tab.
03:35
Here, you can make the cutter longer.
03:39
Under Geometry, in the Length below holder field, enter 1.5,
03:44
and then click Accept.
03:47
In the Browser, right-click Adaptive1 again and select Generate.
03:52
This regenerates the toolpath with the changes you just made.
03:57
In the Browser, next to Adaptive1, the progress of the recalculation displays and the canvas updates.
04:05
Now, you must run a simulation to see if you have fixed the issue.
04:10
With Adaptive1 selected, from the Toolbar, click Simulate.
04:15
On the Simulation player timeline, all the red collision marks have disappeared, save for one.
04:22
Click somewhere close to it on the timeline to watch the collision.
04:27
You can see that, this time, the collision is with the toolpath and not with the tool holder.
04:34
But there is enough material to be able to optimize the toolpath and fix the collision.
04:40
With 2D toolpaths, your only choice is to edit the tool manually
04:45
if you want to increase the length of the tool.
04:48
But first, you need to finish off the scallop toolpath.
04:53
In the Browser, select the Scallop1 toolpath and, on the Toolbar, click Simulate.
04:59
In the Simulate dialog, deselect Stock.
05:04
When you simulate the toolpath, you can clearly see that the tool holder is colliding with the part.
05:10
With 3D toolpaths, there are ways of dealing with this so that you do not have to worry about manually calculating this.
05:18
In the Browser, right-click the Scallop1 toolpath and select Edit.
05:23
In the dialog, on the Tool tab, enable the checkbox next to Shaft & Holder to see the collision options.
05:33
Expand the Shaft and Holder Mode drop-down to see the options to trim the toolpath,
05:39
to detect the tool length, and to fail on collision.
05:44
Fail on collision stops the toolpath from calculating once a collision is detected.
05:51
Trimming the toolpath trims the areas of the toolpath where the holder collides.
05:57
For now, click Cancel.
05:59
In the Browser, right-click the Scallop1 toolpath and click Edit Tool.
06:05
In the Edit Tool dialog, open the Cutter tab, and, in the Length below holder field,
06:12
notice that the length is 0.85 inches.
06:16
Click Accept.
06:18
In the Browser, right-click Scallop1 again, and this time click Edit.
06:24
In the Scallop dialog, in the Tool tab, under Shaft & Holder,
06:30
expand the Shaft and Holder Mode drop-down and click Detect tool length.
06:35
Leave the Holder Clearance field set to 0.2 in.
06:40
Click OK.
06:43
Fusion recalculates the toolpath.
06:46
In the Browser, next to the Scallop1 toolpath, a soft warning appears.
06:52
Click it, and a warning opens that says that the tool has been updated from .85 inches,
06:59
which is what the original tool length was, to 1.3275 inches,
07:05
which is what the tool needs to be to maintain the 0.2-inch clearance between the part and the tool holder.
07:14
Now, in the Browser, select the Scallop1 toolpath again,
07:19
and, from the Toolbar, click Simulate.
07:22
In the Display tab, under Toolpath, expand the Mode drop-down and select All toolpath.
07:30
In the canvas, pan and zoom to a very low part of the tool.
07:36
As the simulation plays, you can see that the tool holder no longer collides.
07:42
The tool is still red because, before this, you did not simulate removing the material.
07:49
But, for this example, the only thing you need to ensure is that the tool holder no longer collides with the part.
07:57
Save the file.
