I'm gearing up to build a machine to do some cuts. My current goal is to cut 6061T6 Aluminum.

I have questions that I can't definitively find answers to via search.

What is the difference between a router and a mill?

Can a router be built to produce the same cuts (and accuracy) as a mill?

Work pieces wouldn't be larger that 12"x8" but will require profile cuts.

This will be the first of my machines and I will be working towards larger machines.
