In many milling operations the cutting tool must step over and make several adjacent cuts to complete machining a feature As a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is usedJul 01 32 Every mill is limited in cooling surface area and therefore limited to the maximum amount of energy that can be used for grinding This dictates the installed motor power for a mill The nominal energy density of a mill is the available energy per volume of milling chamber Energy Density = Installed Motor Power kW Mill Chamber Volume liters
