I've been pouring over Bob Warfield's wonderful site www.cnccookbook.com for the last week. He talks about dry machining aluminum, but it seems his definition of dry is "not flood". I'd like to machine aluminum actually dry and wonder how I should change my feeds and speeds in G-Wizard? From reading Bob's post it seems like I should alter my SFM, but by how much when completely dry is not spelled out.
I will be taking 0.05 WOC, .1875" DOC passes through 6061 with a 3 flute 3/8" endmill made for Aluminum at my roughing stage. G-Wizard suggests 49 IPM @2000RPM on my X3 mill. Any suggestions for a better IPM or DOC (WOC is fixed in my setup)? Can I really run that fast dry?
Attached is a picture of my project for this weekend:
