In this video, you’ll: review collisions for toolpath adjustments and confirm tool holder clearance.
00:11
The Simulate tool detects collisions in toolpaths and provides information that helps you adjust toolpaths to resolve these collisions.
00:22
Open the file Stock Collisions.f3d in the Manufacture workspace.
00:29
A setup and the toolpaths required to manufacture this part have already been applied.
00:36
Before machining, it is good practice to review the toolpaths in a setup to make sure that there are no collisions.
00:44
In the Browser, select Setup1, and then, on the Toolbar, Actions panel, click Simulate to open the Simulate dialog.
00:56
From the Simulation player controls, click Play.
01:02
In the canvas, notice that there are some red marks along the Simulation player timeline.
01:08
These indicate collisions.
01:11
Speed up the playback.
01:14
You can see that, as the simulation moves through the collisions, the tool turns red at the moment when it collides.
01:22
Notice that the collisions in these toolpaths are caused by the tool colliding between the tool holder and the top of the part.
01:30
Close the Simulate dialog.
01:33
To resolve these collisions, you need to edit the toolpaths in which they occur.
01:40
From the Browser, right-click the toolpath Adpative1.
01:46
From the shortcut menu, select Edit.
01:50
In the Adaptive dialog, enable Shaft & Holder.
01:55
Then, expand the Shaft and Holder Mode drop-down.
01:59
Select Detect tool length.
02:04
With this selected, the tool is automatically extended further out of the holder
02:09
to maintain the specified safe distance between the shaft or holder and the workpiece.
02:16
In the Holder Clearance field, specify .1.
02:21
Click OK.
02:23
The toolpath recalculates and displays in the canvas.
02:28
Now, in the Browser, other toolpaths indicate errors.
02:34
Select all the toolpaths and then, from the Toolbar, Actions panel, select Generate.
02:42
The toolpaths update.
02:45
From the Browser, select the Warning icon next to Adaptive1.
02:51
A dialog displays and indicates that “the tool length has been updated to ensure that the holder doesn’t collide with the part”.
03:01
Close the dialog.
03:03
Simulate the setup again.
03:06
As the simulation plays, on the timeline, you can see that the initial collisions are gone,
03:13
but that there are other collisions which occur later in the timeline.
03:18
Once the simulation arrives at the collision, in the canvas, review the interaction between the tool and the part.
03:27
Notice that the flute length of the tool is not long enough to machine the face of the part.
03:34
Close the Simulate dialog.
03:37
To resolve these collisions, edit the tool.
03:41
In the Browser, right-click Adaptive1 and select Edit Tool.
03:47
The Edit Tool dialog displays.
03:51
Open the Cutter tab.
03:54
Here, you can make the cutter longer.
03:57
Under Geometry, in the Shoulder length field, enter 1.25.
04:04
In the Flute length field, enter 1.125.
04:10
An error displays, indicating that the length below the holder must be larger than the shoulder length.
04:16
Increase the Shoulder length to 1.2, and then click Accept.
04:23
The toolpaths should now be free of collisions.
04:28
In addition to reviewing toolpaths for collisions, the Simulate tool also indicates gouging and excessive stock.
04:37
To see this, from the Browser, expand Models, CAM Root:1.
04:45
Toggle OFF the visibility of Base Bracket 1.
04:49
Now, under Setups, click Setup1 and, from the Toolbar, Actions panel, click Simulate.
04:60
From the Simulation player controls, click Play.
05:05
In the Simulate dialog, under Toolpath, ensure Mode is set to Tail.
05:12
Under Stock, ensure Colorization is set to Comparison.
05:19
In this instance, in the canvas, a large area of the part is colored red,
05:26
which indicates gouging.
05:28
Close the Simulate dialog.
05:32
To resolve the gouging issue, edit the toolpath that causes it.
05:37
From the Browser, right-click 2D Contour2 and select Edit.
05:44
From the 2D Contour dialog, open the Heights tab.
05:49
In this case, the information within the Heights tab can be left as-is.
05:55
Open the Passes tab.
05:58
Under Stock to Leave, in the Axial Stock to Leave field, enter 0.
06:05
Click OK.
06:08
Simulate the setup one more time.
06:12
Now, the only gouging that remains occurs during the chamfering toolpath along the part,
06:18
but that gouge is desired in this case, as it has not been modeled on the part.
