In face milling, a rotating tool mills the component to create a flat surface. Indexable mills are generally used here. Productivity (stock removal rate) and surface quality (roughness) play a key role in face milling applications.
In many cases, an inclined cutting edge makes sense with face mills. The pressure angle of the cutting edges influences the direction of the cutting forces. Because the forces are distributed equally in transverse and axial forces, a 45° pitch is often the ideal compromise. Higher productivity is made possible by dispersing the cutting forces in equal measure in the direction of the spindle. In the case of thin-walled components, a 90° working angle is recommended in order to reduce the pressure applied on the workpiece. Another option here would be cutters with round inserts. The round inserts flexibly control the distribution of force via the plunging depth. A depth of cut equal to 50 per cent of the insert diameter corresponds roughly to a working angle of 45°.
