This might be a bit if a daft question but I'm vaguely starting to see the light at the end of the tunnel in my build and I'm just trying to manage my expectations here. What would be considered "good" performance for profile cutting/slotting alu on a DIY 2.2kw gantry type router in terms of dept of cut and feed rates with a decent surface finish? I'm taking about real world numbers for routers here and not the stuff that is spit out by the feed/speed calculators for high speed/ high power VMC's. I've been cutting alu for a long time on my big router and my best surface finish for slotting/profiling is at around 1000mm/min, 0.5mm depth of cut and 14000rpm with a 6mm cutter. I'm hoping for better with the new machine. What's your experience with your machines or any thought on what "good" performance should be?
