A bit confused here.

MC program has the half inch 2 flute endmill speed rate suggested at 12 ipm, but this does not take into account the depth cut I have set at .125..

I am running 2hp Industrial Hobbies mill around 3,200 RPM. What depth cut should a 7/16 or 1/2 two flute endmill Tin Coated and HSS be doing? If the depth cut is .125 what feed rate should I be running at? Or is .125 too conservative for 6061 aluminum.

The part I am cutting is 25" long about .75 deep with pockets and so forth. Right now with 12ipm feed rate at .125 it is taking about 6 hours. Looking to reduce this time without wearing out stuff
