Engraving on 3D part - minimum corner radius

[tysseng]

Hi,

I wish to engrave a logo made up of rectangles, onto a 3D part I assume will be milled (The part will have a cavity and threaded holes on the opposite side of where I wish to engrave the logo).

When running Price/Analyze, I'm told that I have to increase the corner radius to 1.27 mm. However, if I make the logo using through-holes, I can get down to my desired 0.508 mm corner radius.

Can anyone help me figure out a good way of (if at all possible) achieving my goal of ~0.5 mm corners? The depth of the engraving is not terribly important, as long as it is clearly visible after sand blasting/bead blasting the part.

Oh, and I intend to make the part out of 12 - 15 mm thick aluminum. See attached drawing.

I would recommend doing the logo as a 2D item from ~1/16" sheet metal and affix that to the frame.
