What is "good performance" for cutting aluminium?

haha, scratching, good one silyavski. So, you're say at 0.5 mm DOC I can save cutters as I don't even have to start the spindle, the machine with just scratch it through :-) Ok maybe I'm too gentle on my tools.
3-6mm is huge. I'd be EXTREMELY happy with anything remotely like that. Is that what you could do on the yellow steel machine?

3mm depth of cut will be fore sure if you don't make a major mistake.

The yellow machine i have never had the possibility to push it to the limit. remember there is only 0.8kw spindle. But yes, i have tried it with 6mm bit at up to 1.5 mm depth 650mm/min as i remember and it cuts it like butter. Now the other thing is not the speed but the finish. Its perfect. Thats more important to me.

That's very good news. You are so right, whatever the speed, the surface finish has to be perfect.

Although the above posts deal with router cutting or milling the cut quality on the part is quite good. You can improve the corners by quite a bit by having external loops or corner routines on them.
