Help to resolve tool collisions in a 3D adaptive tool path

[t.g.mandel]

Having had recent successes with a variety of tool paths - facing, drilling, thread milling in aluminum - I am starting to look at some of my 3D wood projects. I would like to use a 3D adaptive strategy to remove most of the material, then follow up with other rest machining toolpaths to carve the final finer details. I am able to do the latter when using a 3D pocket then parallel combination, but I keep getting collisions in a few spots when trying 3D adaptive. I have spent an embarrassingly long time trying different parameter combinations, but the truth is I ultimately do not have the experience to know what is causing the problems.

Here is the set up:

And here is success after a 3D pocket (before a parallel tool path):

Here is one collision area that happens repeatedly near the tail:

I also do not understand what settings to alter so that the material is all cut to the same depth, which should be half the model (I will be trying 2 sided milling with this project as well).

The following are images of one of the settings combinations I had tried:

I appreciate any suggestions and insights that can be provided.

Thank you,

Tom

For best chance of a resolution, try to remember to share your Fusion file if possible.

For this issue, try turning on Rest Machining (From Setup Stock).

Thank you for the reply. I have attached the file.

The only tool path that gives collisions is the 2D adaptive - not pocket or parallel.

It is the first one I run so I did not think rest machining was a factor, but I may be wrong.

If you can offer any insights I would greatly appreciate it.

You're using 3D Adaptive, not 2D. And yes, just turn Rest Machining on and set it to "From Setup Stock". No collisions:

Got it - it worked. I have been working on a different project the last few days and forgot it was 3D - thank you.

I appreciate the help,
