Is there a better way to do this? (4th axis circular milling)

[Anonymous]

I struggled a bit with generating a circular groove on a cylinder, but with some advice here, found that I could generate the form by not going a full 360°. this prevented the "Can't unwind cyclic geometry" error. I then thought that I had the machining figured out by using 2D Adaptive Clearing. This resulted in a toolpath on the surface, but not to depth. I then added a negative value for the depth and got the machining to go to the proper depth. MY question is, is there a better way to approach this problem? I'd like to be able to machine the profile without having to leave that little sliver of material, but am more interested in a good result in the profile itself. My Screencast omits the editing of the toolpath to create multiple depths but shows my thinking on accomplishing the process.(One could also simply use a single depth, but that would be a personal / material / cutter preference).

Hi @Anonymous

Thanks for posting! This is a known issue for our development team, who are working to remedy it.

I like the work-around that was presented on the other thread and here! Another potential workaround could be to draw a sketch on a flat plane and then wrap its toolpath around the cylinder, as illustrated in the screencast below:

Using this technique should allow you to avoid leaving the small sliver of material! Please let me know if you have any questions.

Thank you Paul. The one thing that I have noticed about FUSION 360 is that the development team is very responsive and the online support is extremely helpful. I hope that this gets addressed in the near future. I'll give that process a try and post back here what I find out.

Thanks again

Hey,

What I've noticed is to do a wrap tool path without leaving that wall, is to create your part with the original origin of the cylinder on the y axis. So if the y axis is your cylinder the wrap tool path works.

I have no idea why, but that's what I figured out.
