Dynamic spindle-speed and feed-rate for ball end mill 3D finishing Finishing 3D surfaces with a 3-axis machine and a ball end-mill can be challenging. In a single op, you can have the ball engaged near the tip where the SFM is much lower, and other times engaged near the side where it behaves more like a straight endmill -- and anywhere in between.
