Optimum cut settings for carving in hardwoods?

Does anyone have any ideas what the optimum cut settings would be for carving into hardwoods with the smaller 0.8, 1.0, 1.2 bits?

There are no optimum cut settings. All materials have different densities, and require different settings. With the consideration on the size of the bits etc. We did a live outlining some of the theory behinds feeds and speeds and answered many questions regarding bit choice. CNC Bits & Speeds - YouTube
