Hello,

I am trying to CNC route an aluminum panel. I can't find data on the alloy, it's a Hammond aluminum project box. It's pretty soft. I am currently using a 2 flute, low helix upcut solid carbide bit. It's 1/8" diameter. The aluminum is .0625 thick and I am cutting at .05/pass. I have tried feeds from 60ipm to 200ipm. RPMs from 7000 to 20,000. Pretty much the exact same result at all settings, it's tearing the aluminum pretty badly and leaving a huge ridge on the top. I am becoming convinced that I am using the wrong bit, but I am not sure what bit I should be using. I did try a downcut bit but that balled up and overheated quickly.
Hoping someone can help me get pointed in the right direction! Happy to fill in any missing data I haven't supplied.

Thank you.
James
