Hello All,
I have been making 3D wooden molds for a few months now; and have learned alot about the shopbot and cutting techniques from this forum.
I am currently working on a mold with 1/8" radiuses. Normally, I would rough out the mold with a 1/2" ball nose and finish with a 1/4" ball nose.
Should I rough out the mold with the 1/2" or 1/4" ball nose? I am concerned about the difference in cutting diameter going from the 1/2" ball nose to the 1/8" ball nose.
The 1/8" ball nose is 1/4" tapered shank end mill.
Also, any advice on feed and speed for 1/8" ball nose in maple wood would be appreciated. I use an online chip load normally if I am cross checking myself.
