Fillet Design Problem

[TRIGOLICNC]

Hi.....I am trying to generate a fillet ONLY on the highlighted line in the the attached pictures. When create the fillet, it generates up the entire wall length. I understand why it is doing that, but I assume there is a way to generate only what I need? When I machine this feature I want the upper boss to be profiled with square/straight edges, but the lower pocket to have a corner radius. Thanks in advance! 🙂

What I am showing is only one method of how this can be done.

OK....That workaround worked as far as creating the radius, but now that created another problem. Before I split the body i had a toolpath that pocketed the floor of the large cavity. After the split body was applied and then created a combine so they were all one again, i can no longer pocket the floor of the large cavity (no passes to link error). I went back to an old rev to confirm that it was in fact doing what i wanted, it was. What am i doing wrong? Thanks

OK. Don't create tool paths before your done designing the thing 😉

Well... let me take that back. Don't create tool path before you are more familiar with the modeling tools and limitations and workarounds in Fusion 360. That will provide you with a better I understanding which edits your toll paths will survive and which not.

Here's another attempt. If that works in your particular case, I don't know. You've not shared your design.

And another one.

Hi Peter...I have never shared a file before, but I think the link below will work? I assume the CAM features will follow as well even though I had to create the link from the "Model" tab? I removed all of the irrelevant features and tool paths except for the current issue.

1.) The RED, YELLOW & GREEN faces are what I am trying to machine out.

2.) The GREEN features are the fillets I had questioned in original post. I only modified the one small GREEN pocket on the RED feature to show the CAM issue I have. (used your trick from earlier reply...Thanks!)

3.) When you run the first CAM cycle to cut the large pocket you'll see that the YELLOW tool pocket tool paths extend beyond the GREEN cutouts. The RED pocket toolpaths stay inside that boundary and don't extend outside of that feature.

4.) The reason for this question is that when I machine both GREEN pockets with the 2nd toolpath, it will leave a radius in the corner. The break the edge I run a deburring tool along that profile (3rd tool path), the problem is that when the part is modeled with square corners, the deburring tool path follows that contour not knowing there is a really a radius left behind from previous tool and gouges in the corner.

....Unless there is an easier way to get the same result I am trying to do?

Thanks!

I would post this quetion in the CAM part of the forum, and maybe link to this thread. I am not familiar with the CAM in Fusion 360 but I believe the guys in the CAM section will be able to answer this part of the question there.
