Milling speeds and feeds recommendations

Is there any accounting for the inconsistancy of bossing? Go figure! My current boss doesn't seem to object to the cost so why not? I had a previous boss that was touting the benefits of WD-40 and then when I started using it 'consertively' because it isn't cheap, the boss criticised me for using the expensive stuff. I also like Kerosene for cutting Aluminum but am quickly swtching to WD-40 which smells better and seems to work better albiet more costly.

Therefore when surfacing a wide swath, the fly cutter can possibly outperform the trick AB Tool unless we have a larger diameter (1.5') as you suggest. I treid it once on the Bridgeport and it works great but B'port can't take advantage of the high rpm which is limited to a little ofver 3,000rpm. I think we have that same tool which we use on our Haas verticl mill and KOMO router for Aluminum. Tom RE: Feeds and speeds for aluminum milling loojian (Mechanical) 22 Feb 04 04:54 I'd be most grateful for any recommendations or comments on how I might reduce my machining time. Can also try carbide tools, but have hesitated doing so since first attempts 2 yrs ago resulted in lot's of broken tools. Seeems logical that an objective should be to remove the most material at powers close to the rated spindle motor power. I have not yet tried using roughing mills for initial stock removal, though this seems an obvious thing to try. These components took quite a while to mill the first time around at the above.

Am using an inverter for continuously variable speed control between 50-3600 rpm.ДЄm contrmplating the need to mill relatively large (for me) components from blocks of materials, say 3' x 6' x 14' blocks. Spindle motor is rated for 3600rpm/3HP w/2-speed gearbox. I'm using the following feeds and speeds for milling alloy 6061 and Fortal (7075) aluminum plate, bar and billets.Д .250' dia x 2-flute end mill.15 ipm x 2500 rpmД .500' dia x 2 flute end mill.8 ipm x 1250 rpmД®ndmills are center-cutting TiCN coated HSS
