Help!
I am fabricating my own engine mounts for 2 riggers and need to cut about 1/8" deep by 5/8" wide out of the ends of the engine rails. I am using high strength 2024 aluminum and using a
High-Speed Steel Three-Flute End Mill for Aluminum in a variable speed drill press to cut the aluminum held in a bench vise. I know my upright heavy duty drill press can develop some good speed but I have now heard there is a chart for such a thing and depending on the type of aluminum determines the RPM needed. Can anybody help with the RPM so I dont burn out the bit? I am not a machinist and dont know the terms really well but I believe I have and end mill for a box or square cut. The mill bit is from McMaster-Carr stock number 2716A62 http://www.mcmaster.com/#catalog/121/2489/=wygjjx
Any help would be appreciated.
