Re: CNC Tooling

This thread inspired me to try to push my endmill a little harder on a big job I'm doing the first run of.

Lakeshore Carbide 1/4" carbide square corner 3-flute variable helix ZrN coated.

HAAS Mini Mill @ 6000 RPM. Flood coolant.
Cutting .2 deep, 20% stepover.

It's loving running at 144 IPM. If I had a 12k RPM spindle, I'd probably be able to run it at 300 IPM.

HSM toolpaths really do wonders.
