I have a Pcnc1100 S3, I bought a 3 flute 2" face mill to use on some 6061, It looks like I could run about 475rpms at 2ipm feed rate? does that seem about right? I don't know at what depth of cut.

Aluminum I ran max spindle speed with a 2" ripper mill. A good starting point would be max speed at .05 deep 1.8" step over at 30ipm. Flood cool if you can.I was using a solid r8 holder, not TTS
