I bought a few YG1 end mills. 1,2 and 3 flute and a 3 flute rougher for cutting aluminum. All 4mm apart from the rougher. I am a little confused that the YG1 recommended cutting conditions for the 1 flute (E5E47 series, 4mm) 15000 rpm, 1800 mm/min feed 190 m/min Vc and 0.120 mm/tooth. If I run these speeds on my machining centre, slotting 1.6mm think aluminium, full depth of cut, it cuts perfectly. The edge quality is great and chips clear well. FSWizard however suggests I run the bit 15000 rpm, 519 mm/min feed 0.034 mm / tooth. This results in the aluminum instantly melting and the end mill having aluminum welded to it pretty enthusiastically.
The interesting thing for me is that the 2 flute 45 helix E5521 4mm has YG1 recommended cutting conditions of 10000 rpm 1100 mm/min feed 0.055 mm / tooth. Slower feed (but also slower RPM) than the 1 flute. The 1 flute doc also says it slots at 1.5D where as the 2 slots at 0.5D.
Is HSMAdvisor / FSWizard wrong for aluminum specific end mills? Am I doing something stupid using it? If I attempt to run any end mills at the numbers it recommends they melt and in my wisdom I didn't look at the YG1 numbers first... so a 3 flute and 2 flute got aluminum welded to them. Is the 1 flute the best way to slot 1.6 mm thick aluminum? I'm cutting parts for bending in my press brake. These YG1 alu powers are basically magic compared to what I've used before. I haven't tried the rougher yet. I'm starting to think it won't be worth tool changing some of areas as the 1 flute is so fast.
