This plate was in fact cut on a Haas CNC mill. Machining credit goes to wafertech, our generous sponsor.

Its possible that the white paper background of this photo is making the shiny edges seem dull.

As I was not the machinist on this project, I can't give you the exact numbers. But I was there while this was being made and I can tell you what I remember the machinist saying. Something like 5000 rpm spindle speed with 12 ipm feed rate. The bit was .25" two flute end mill, and I'm pretty sure it was HSS. They did the thickness of the .25" plate in a few separate passes.
