Converting to millimeters:
0.0508mm - 0.1016mm and 762mm/min and 1016mm/min.
Thinking through this a bit further: if I went down to 0.05mm I should be able to safely go to 1120mm/min. When I went from 0.2mm to 0.1mm I was able to triple my feed rate. In theory if I go to 0.05mm I should be able to do triple my feed which is 1680mm/min which should halve my overall run-time again.
I'll play around with this on my next run of Aluminum; worst case scenario I just decrease my feed on the fly in Mach3.
I also forgot to mention I'm using an 1/8 endmill. I have one 1/4, I haven't messed with it much since I've had so much success with 1/8.
