Steep and shallow UNDERCUT

How can I get finer results on undercut with steep and shallow? I know it's still quite new, but I bet someone here has found out something about it.😀

 

Sample file is attached.

"finer results"

Could you please elaborate on what the problem is? Perhaps post an image if that helps?

I could suggest totally obvious things like:

Reduce the Stepover
Reduce the Tolerance

But I guess you know that and this isn't the cause of your problem

I looked at it, the beginning is pretty bad where it retracts a lot for no reason. Maybe lowering the top height by just a tiny bit could help, not sure.  After that about on mid-height there are some areas where the toolpath is not smooth.

In general it is pretty cool tho!  I don't have the extensions enabled at the moment so I can't do anything with the path, but when I get some time I will try them out just for this toolpath.  I feel it is probably possible to do some engine ports now, maybe... it looks like it might work...  It is definitely a step in the right direction! 🙂

Ok.... If you get the opportunity to try it again, and you feel the result is bad, let me know.

If so.. Hopefully I can get hold of your project so that our development team can take a look at it.

Just to clarify, I am not the same person as the OP, I was just adding a useless comment.  I will step out now, but I just want to clarify that OP issue is not dealt with yet 🙄

It is definitely possible to do some engine ports. I have already done this a few times. Best to use tool collision avoidance from point in my experience so far.

Got amazing paths the first time I tried it. But now it's getting a little clumsy. can take a picture possibly of how it will be after machining next week.

yes is definitely the right direction for Fusion 360. Hope there comes a 5 axis roughing cycle soon

Ya I guess it depends on the ports...  I am talking ports that have undercut due to the elbow turn, that was not possible before this new functionality, not in 1 toolpath.  I've done ports too before in Fusion, but required more than 1 toolpath.  I should have specified the 1 toolpath thing.  1 continuous smooth toolpath finishing the entire port that has undercuts areas.
