Fixture Object Collision - CNC Machine

lucasliraAU — Mon, 19 Dec 2022 18:34:42 GMT

Hello friends!!

Well, I'm performing a machining configuration as you can see in the image below.
In the fixation option
(Fixture)

I informed Fusion 360 that the Cylinder is a fastener, but when I run an Adaptive Clearing process, it still continues to create a material removal route, disregarding the cylinder as a fastener and making inappropriate collisions for the execution of this process.

someone could give me a support to work around this conflict in the execution of this route.
Thanks for your attention!

Yep, Adaptive and other 3d toolpaths aren't actually modified when a collision with a fixture is made. We are working on improving that behavior, but it's quite a ways out at the moment.

To constrain or restrict your toolpath from violating any area you need, you're going to have to use Boundaries, which can be constructed with sketches. If you could share your file, we can toss a few options at it and get you more detailed answers.

Hi, @seth.madore

Thank you for your attention to this case!

Well I'm leaving my shared file here so that some limitation can be imposed on the cylinder region which is a fixture in my machine orientation!

Thank you very much!

Model available!

Here's the idea:

Here's the result (with no collisions):

Hi, @seth.madore

Thank you for taking the time to provide an efficient solution like the one shared here!

I would like to know, did you create a 2D sketch over the model to determine the selection in (Geometry - Adaptive), did this limit the toolpaths - Am I sure of that?

Yep, a 2D Sketch in the Design space is all that's needed. It doesn't need to be above the part, it can be on any plane or even below the part. I then select that as a Boundary with it set to "Tool Center on Boundary" for containment. You should be able to examine the Fusion file that was uploaded 🙂

@seth.madore

Perfect understanding!

Thank you for your help!!

Greetings, and an excellent week!!
