The prediction of cutting forces in the ball-end milling process

For this milling process with a ball-end milling cutter, the analysis is much more involved than that for other milling cutters inasmuch as the parameters of interest vary with the radial position across the cutting edge. The main reason is that the geometry of the cutting edge on the ball-end mill is curvilinear rather than linear on the end mill.
