A method I used recently involved a flip op with a radius bit. My radius cutter left a ¼” flat web 1/16” thick between the part and the scrap. I followed this up with a 1/4” endmill and left two ½” 3D tabs in the center of the part. Doing tabs in this manner left the radius cut smooth and unblemished by the tab process. This method is only feasible if it’s OK to have a narrow flat spot in the center of the two radii. In my case, I deliver the parts in the scrap matrix and the customer cleans up the tabs.

Thanks for the explanation and diagram Steve. I was writing my previous reply while you were posting.

I couldn't visualize how to do the tabs and leave a smooth profile on the radius cut, but see how leaving the 1/16" flat can achieve this.

I will ask if the flat would be acceptable as this is a good approach as well. Thanks!
