Is this possible to CNC

[valmeidan]

I did an analysis in solidworks and it said a few features are inaccessible, I am assuming it is saying that because of the radius in these grooves. This part will eventually be cast, but for a quick turnaround for proto we want to machine them. Aluminum, plates, overall length of the part is about 7``x 3.5 ``. have a look at the pic attached, can these features be made? alternatives if not possible?

Yes, they can be machined. It will be machined from both sides.

nothing looks particularly odd ... i'd add fillet radius where you have sharp corners. the item (1) ... looks like you have fillet rad on a external corner, which'd i'd probably make sharp!

another day in paradise, or is paradise one day closer ?

Thanks guys, I honestly have no idea how the machine would cut those features as it is a half circle cut into a boss?

Possibly a ball end-mill

have you thought about 3D printing ?

Did SW complain specifically about those grooves?

The one marked 2 is difficult because of the feather edge.
The other two are easy with a ball type end mill.

The features that trouble me are the small corner radii in the
rectangular holes, which require a skinny cutter projecting very far from its collet to clear the adjacent shoulder features.

The #2 as Mike suggests would have to be milled on the flat after the curve. Otherwise the curve cut would push the material out.
What is the size of the part, and radii?
