Z clearance when milling a 2.5in high aluminum box

As always it seems Winston has a related video to this.

The machine can quite a few things to help you out here. If you truely need to come top side down into the box, you could pocket a recess into your wasteboard to get the box lower and then use a long reach endmill. Or you could have it on the front of the machine, similar to something like this: CNC Finger Joint Box
