David,
Forget G-Wizard. I have. It's not that specific and not particularly helpful.

On this thread, I had a go at milling 1050A aluminium cut using a 2 mm 2 flute TiAlN coated solid carbide end mill at 0.1 mm depth per pass, 900 mm/min feed rate, 30 mm/min plunge rate and 12,500 rpm spindle speed. It was a mess but the piece was recoverable with a lot of manual filing. I subsequently realised when trying to use the same cutter a few weeks later on acrylic sheet that it should have been run in the REVERSE direction. D'oh!
I'm afraid that I haven't tried another cut to see how big a difference that would have made, but I suspect it would cut o.k. running with the flutes in the correct direction.
Nevertheless, harder grades of aluminium should mill better and the application of a supply of compressed air to the cutter for cooling and to aid chip removal is highly recommended. I don't currently have a compressor.
