Hey,

I have small rectangular tensile specimens (gauge Width 0.112) that I need to face down so they are flat. They're 0.182 Wide and 2.0" long. They're thickness varies from one end where it is 0.100" thick to 0.070" thin. I plan on milling an aluminum block so that It is about .050" short of my vise jaws and resting the specimen on there. I'm wondering if anyone has feed or speed suggestion along with depth of cut. I'm thinking either two cuts 0.016 deep or 0.028 and then 0.005.

I plan on using a solid carbide 2 flute 0.25" Diam TiAlN Coated end will at 4,000 RPM with .003 IPT and flood coolant. Is this good or any suggestions?
