A New Milling 101: Milling Forces and Formulas
Workpiece Material K FactorsTool Cutting Edge Anglein GeneralDifferent angles at the cutting edge generate different-thickness chips. For example, a 45-degree cutter has equal radial and axial forces, making it less demanding on spindle bearings and enabling higher feed rates. This is usually a good choice for face milling as it provides a smooth entrance and exit to the cut while offering high surface finis...
