A highfeed mill requires a light axial depth of cut but when run at this light depth the tool permits feed rates higher than milling cutters with more conventional designs the reason is chip thinning the key to a highfeed mill is an insert with a largeradius curve to its cutting edge see figure 10.
A smaller ball interpolated exposes more of the surface to a faster moving cutter leading to a better finish but the smaller cutter can flex more hence the need to balance these two factors if you have a 4th axis or 5axis mill you can try sturz milling to combat the slow moving tip see below for details.
