Machining a 3D surface when the tool exactly matches it

[JetForMe]

I'm modeling hemispherical cavities in a cube. As it turns out, I have a ball-nose end mill of exactly the same size.

What's the best way to do this? A full 3D path, or some kind of shallow drill operation?

You can use drill, set the hole mode to Selected Points and select the cavity edge.

Then on the height tabs set the Top and Bottom height to Selection, select the edge and set the bottom offset to the depth of the cavity.

Just a note I would use the Counterboring drill cycle as well. This will let you put in a small dwell (.3 or so) so the tool can finish cutting to depth. If not you may find the sizes will vary greatly.
