Has anyone cut aluminum with 40% silicon carbide in it . I cant seem to find any tools that hold up . Does it like light cuts, heavy cuts . I am using Mastercam dynamic milling not having any luck .I am trying DLC coating Diamond Like carbon coating to see if that holds up . It just where's the tool edge down . It doesn't chip the tool more just rounds the cutting edge over . Any help would be greatly appreciated .
Thank you Chris
 
Whats your DOC, step over%, whats the life time of a tool currently? what kind of tooling are you using? HSS, Carbide,.. coating etc. Tools rounding over almost sound like melting, I know with all aluminum it tends to gum up in the cutters flutes.
