311FORMULAS AND DEFINITIONSSpecific Cutting Force (kc)Specific cutting force is the force required to cut a material, measured per unit area of the material being cut. It is usually expressed in Newtons per square millimeter (N/mm%u00b2).Formula:kc = Fc AcWhen:kc = specific cutting force (N/mm%u00b2)Fc = cutting force (N)Ac = cross-sectional area of the cut (mm%u00b2)
