HEM is high axial, low radial stepovers vs traditional low axial, high radial. Dynamic milling is a type of toolpath in CAM programs that keeps cutter engagement consistent no matter the part feature so you can use higher feedrates without having to worry about snapping the tool as it goes into a corner because it will take the corner in several cuts.
Pic related is a rough example of a dynamic toolpath. Notice that there's never any real straight lines and no sharp corners. 95% of the lines that look straight are the tool back feeding through air to position into the next cut. The load on the tool is more or less unchanged throughout the whole toolpath so if a feedrate works in one spot it will work the same anywhere.
