Just thought I'd share probably the best work so far done:
Roughed with 5/8" straight flute, finished with 1/8" ball nose and 1/16" remachining... all carbide
it took about 5-6 hrs. very rewarding
used Rhino 3D and MadCAM and planar finishing.
edit: got the feedrates wrong and accidentally discovered my machine is capable of 160 IPM! pretty sweet. Still trying to find the optimal surface finish feed rates, doing 80 right now.
