creating a concave radius

adventuremetal — Fri, 31 Aug 2018 00:20:58 GMT

I can't figure out how to turn the slot sketch into a concave radius on the attached file. This part is going to be machined and the slot milled with a 1.25 diameter end mill. Any help would be much appreciated.

Thanks,

Roger

A bunch of ways to do this; one- a swept profile -is attached. I'll include a screencast in a moment.

...and a narrative. Or another broken attempt to include a screencast.

With the slot diameter of 0.625" and a 1.25" ball nose end mill, you could just plunge along the intended length to a finish depth of 0.08373" for a shallow concavity.

An even simpler way using only the existing Sketch, an Extrude, Fillet, and Combine:

Thanks for the help. Use of construction plans is something I still need a lot of practice with.
