How Was This Milled?

[Paul in OKC]

It's an optical illusion from that stand point. I agree with the dove tail cutter on a vertical rotary table.

Ok, I can see that the cut gets shallower as it goes toward the center. that explains why the cut is tapered.

But it seems like it would be hard to get a dovetail cutter at such a steep angle. It would seem to me that the shaft of the dovetail cutter would need to be pretty long.



It looks to me like the cut pattern fits this solution as well.

Instead of a conventional dovetail cutter, it looks like a cutter mounted in a universal cutting frame, as used in ornamental turning, would do the job.

As above, the profile of the innermost part of the cut gives away it was a dovetail, I'm pretty sure

It looks to me like it was mounted on a 4th axis and then the head slightly nodded or tilted, something, so that the dovetail could get in there,

It looks to me that it would be cake to make with a horizontal mill and rotary table, even easier if controlled by cnc.

Well, let's have a mill-off......see who can come closest to duplicating that profile.

Is there a bonus if it is done on a lathe?

Dovetail cutter on 5th axis

I think it could also be done on a horizontal with a radius form cutter, on a tilting rotary table, the lines in the cut do not show a small endmill in use, and the corners are sharp. Also the optical illusion could play, is the part concave or convex or flat? Interesting tho

Hhhmmmmmmm where did I put that piece of aluminum plate?
