I just bought a HAAS VF-4SS. I am VERY new to machining. I am trying to mill a .750" wide slot into a 2.500" wide x 2.250" long x .500" thick steel bar. The slot goes all the way through the .500" and 1.375" into the 2.250" side.
I have tried to use a 1/2" roughing end mill to start it and then finish it with a 1/2" 4fl end mill. I keep breaking both.
Any feedback or tips at all will be appreciated.
