In this video, you’ll: determine collision avoidance strategy.
00:08
Open the file Strategizing collision avoidance.f3d in the Manufacture workspace.
00:16
In the Browser, under Setups, select Setup1.
00:22
Notice that the part and the stock are the exact same body.
00:26
This is to aid in the visualization of the toolpath.
00:30
Also notice that the part has small interior features and is rather tall.
00:36
If this part is manufactured in a 3-axis environment, the tools used would require long stickouts.
00:43
Therefore, a multi-axis approach would be much more efficient.
00:49
Begin by applying a 3D toolpath.
00:53
From the Toolbar, expand 3D and select Steep and Shallow.
00:60
This type of toolpath is a hybrid strategy that combines the styles of Scallop and Contour into a single operation.
01:09
In the Steep and Shallow dialog, under Tool, click the Tool selection prompt.
01:16
This opens the tool library.
01:19
From the Fusion 360 Library, select Sample Tools – Inch.
01:26
Under Filters, Type, select Ball end mill.
01:32
The list of tools updates to just the filtered results.
01:36
From here, select the 1/4" Ball Endmill.
01:41
Finally, under Cutting data, select Aluminum – Finishing.
01:48
Click Select.
01:51
Back in the Steep and Shallow dialog, enable Shaft & Holder.
01:57
Then, open the Geometry tab.
01:60
In the canvas, pick an outer edge of the interior feature.
02:05
Back in the dialog, enable Contact Point Boundary.
02:11
This allows boundaries to limit the tool contact points, rather than the tool center points.
02:18
Now, open the Passes tab.
02:21
Under Passes, ensure that Priority is set to Top first.
02:28
Under Steep Passes, expand the Direction drop-down and select Both ways.
02:34
Then, in the Stepdown field, enter .02.
02:39
Under Shallow Passes, leave Type set to Scallop.
02:44
Enable Continuous.
02:47
Generating a continuous toolpath has fewer tool-lifts between passes, which provides a better surface finish.
02:56
Set the Direction to Both ways.
02:60
In the Stepover field, enter .02.
03:05
Next, open the Linking tab.
03:08
Under Linking, expand the Retraction Policy drop-down and select Minimum Retraction.
03:15
This moves the tool straight up to the lowest height where the tool clears the workpiece,
03:21
plus any specified safe distance.
03:25
Click OK, and the toolpath generates, which can take a few moments.
03:32
Once the toolpath is calculated, it appears in the canvas.
03:36
Review the toolpath and notice that it only applies to areas of the part where no collisions with the part itself will occur.
03:45
From the Browser, right-click the toolpath and select Edit.
03:50
This opens the Steep and Shallow dialog again.
03:54
Open the Multi-Axis tab.
03:58
Under Tool Axis, leave Primary Mode set to Vertical.
04:04
Then, enable Collision Avoidance.
04:08
Collision avoidance lets you tilt the tool axis to avoid collisions between the shaft or holder and the part.
04:16
As collisions are avoided, you are able to reach more areas of a part and machine more complex parts.
04:23
Expand the Avoidance Mode drop-down and ensure it is set to Automatic.
04:30
Next, enable Tool Axis Limits.
04:34
In the Maximum Tilt field, enter 110.
04:40
Expand the Areas Beyond Limit drop-down and select Machine at maximum tilt,
04:46
which keeps the tool axis at the limit upon reaching it.
04:51
Click OK.
04:54
With these options selected, the toolpath calculation will take several minutes.
05:01
Once it is finished, from the Browser, select the toolpath.
05:06
Then, from the Toolbar, Actions panel, select Simulate.
05:13
This opens the Simulate dialog.
05:16
From the Simulation player controls, press Play.
05:21
Notice that as the tool descends to deeper parts of the geometry,
05:26
the tool tilts to machine those areas, avoiding colliding with the part,
05:31
and the tool machines the part in the most efficient way.
