I am looking to do a small machine build that will require machining .75" 6061 Aluminum on a DIY cnc build. I have already done some tests and found that I can machine aluminum successfully.
My question is this. I have several choices of 6061, flat bar, flat plate & cast aluminum plate. I can get the size for what I need in any of these types, but I don't know which to get. I will be doing most of my machining with a 1/4" coated 3 flute EM with some of the thru holes with a 1/8" coated EM.
Any help would be welcome. Here is the site that I am looking to purchase from.
