I''m finishing a race track shape with a 1/8" ball.

Ballnose Surface Finishes

In this case, to achieve a maximum scallop height of a tenth (0.0001″) for an RA finish of 100, we need a 0.011″ stepover. That''s about 2.2% of the tool''s diameter. Feeds and speeds for ballnosed cutters can be a bit tricky because the effective diameter of the …

Ball nose mill and mill marks? | MCAD Central

 · When using a ball end mill with a small step depth or scallop height, you can, and probably should, boost your feedrate. The reasoning is simple. As the depth of cut gets shallower, less of the tool is engaged in the part. The chip becomes thinner. Radial force becomes correspondingly less.
