Why is it that right after the tool breaks you realize what you did wrong? It seems you can't plunge a 1/2" d 3 fl roughing end mill into aluminum at 132 IPM. oops.
I was leaving too much material for my 1 degree tapered end mill to clean up and just wanted to redo the toolpath out a little father, but I had full depth set for the last pass.
Thank You, Randy
