Rounded Chamfer edges with basic

[thebeatlesin3d (Christopher Sileo)]

I’m making some simple round and square boxes with lids. For this one I’m using alder.

I see you can get a nice sharp chamfer with a V bit, but can you round over the edges with Carbide create basic?

That must take some pretty crazy tool paths?

I’m an expert model or end a 23 year auto desk user I just haven’t had a chance to jump into fusion to do any serious 3-D carving.

Thanks

Cracking the code - round over letters

Well I feel weird with this being my first post on the forum (hello by the way); but I’ve been silently watching, learning, and perfecting the craft so thank you all. Recently I have been figuring out a way to have round over corners on all of my letters without final finishing with a router, and without multiple passes with an end mill to build it up. So here’s what I have come up with… By creating two contour cut tool-paths in carbide create I am able to first use a tool path for a 1/16 end …

If I understand your question you want a rounded over edge on a box. There are a lot of complicated ways to do it but you could simply use a round over bit. Not just any round over bit. Most round over bits have a bearing. Using a bearing router bit on a CNC is bad. If you could find a round over bit without a bearing, which I think is impossible, you could take a bearing off a round over bit. However most have a stem sticking out that the bearing goes on. That could still potentially cause problems because using a BitSetter would cause the bit to be too high to ever cut the edges. You could compensate for that but it would be some work to figure out how much deeper you would need to set a contour or pocket to compensate for the stem. Also depending on thickness of material you could potentially drag the stem over the spoilboard or material and cause loss of steps.

So if you could get a round over bit with no bearing you could make a custom tool and cut using a contour with no offset to the depth of the round over.

The champher is easier to do with your vee bit but that is an ascetic choice for your design. A round over is possible but problematic.
