- unless you absolutely cannot create a profile without a 1/8" endmill (this is probably not true, this would mean that you have a radius somewhere that is smaller than 1/8") do not use an 1/8" endmill
- in general, use the biggest endmill you can get away with (we used a 1/2" flat end for roughing and a 1/2" ball end for finishing) this reduces machining time and give you a better finish
- if you have a lot of CAM to run and it's going to take a long time, you should probably use a haas Haas machine (area 51 has one, other places might as well) these are enclosed CNC mills that use flood coolant and can run much faster than the mills in Todd shop or the Deep
