Feeds and Speeds 6061
Hello Forum
Due to obtaining conflicting information from online calculators, I approach the forum requesting feeds and speeds for profile cutting 6061 Al using a; 0.375" 4 flute rougher end mill going to a depth of
-1.5" using a HSM milling operation. What say the forum? Thank you!

control make and model
maximum spindle speed of the machine
does the machine have high speed machining ?
how much look ahead does the control have
what are the feed rates that the machine can obtain
what kind of tool holder are you using --end mill,er collet style,ect.

Re: Feeds and Speeds 6061
If you can find a 2 or 3 flute endmill it would work better.
I would break the depth of cut in half and do .75 at a time with HSM. 1.5" might be too much for one go at it. I usually do a 30 - 40% stepover.
If you have good coolant to evacuate the chips I would max out the RPM and do a feedrate of about .004 to .005" per flute. If I'm using a 3 flute at 7500 RPM I usually program the feedrate around 100. ipm.
