CNC mills for 3D carving are round on the bottom. They're called ball mills. From top down, shown are .500, .250, .125 ball mills and tapered mills of .125 x .5mm radius and .250 x 1mm radius. The ones I most often use are the top two. Cutting parts with a CNC is a process. It's not quite 3D and a bit more than 2D.

Here are a few suggestions: The stepover should be between 1/3 and 1/10 of the tool diameter. Use a larger stepover, in the 1/5 to 1/3 range, for soft materials that cannot hold detail well. Use a smaller stepover, in the 1/5 to 1/10 range, for hard materials or materials that can hold significant detail like metal and jewelers wax.
