I've lurked the forums for awhile but decided to finally post as I can't seem to find a good answer to a question that's been plaguing me.
I'm doing some prototype work at a small company and long story short: I'm limited to what tools we have on hand to get work done.
The prototypes are being made out of 6061 aluminum and the only end mills I have available are:
1) 2mm 2F coated carbide
2) 6mm 4F coated carbide
3) 20mm 6F carbide
I've spent some time in Machinery's Handbook trying to make sense of the feed and speed tables but they weren't terribly helpful for a constrained situation like mine. From what I've seen here and other places, the best I can do is run at max rpm (10k for me)??
I'd really appreciate it if someone with more experience than I could help me understand what feeds and speeds to use with 6061 and these tools and especially WHY?? I understand that feed/speed is usually a very unique thing, but I'd be grateful if someone could go out on a limb and tell me what they would do in my situation so I have a reference to base my own plans on.
Other bits: machine is a sharp sv2412s w/ 10k spindle, FANUC 0i-MD, and flood coolant.
Thanks in advance!
