Abstract
A cutting head for a mill configured to rotate about an axis to remove material from a work piece includes a base surface, a side region connected to the base surface, and a top region connected to the side region. The top region defines a central area and a periphery. A plurality of top teeth are disposed on the top region. The top teeth have cutting edges configured to contact the work piece to remove material. Each cutting edge extends from the central area towards the periphery and includes an axially extending peak portion.

A cutting head configured to rotate about an axis to remove material from a workpiece, the cutting head comprising:
- a base surface;
- a side region connected to the base surface;
- a top region connected to the side region and defining a central area and a periphery;
- and
- top teeth disposed on the top region, the top teeth comprising cutting edges configured to contact the workpiece to remove the material, each the cutting edge extending from the central area towards the periphery and comprising an axially extending peak portion,
- wherein the cutting edges-comprise an undercut face below the flat zone, the undercut face being disposed at a non-zero angle relative to the reference plane parallel to the axis of rotation of the cutting head.
A method of milling a workpiece, the method comprising:
- rotating a mill about an axis;
- and
- removing material from the workpiece with cutting edges of top teeth of the mill, the cutting edges extending from a central area of the top region towards a periphery of the top region, the cutting edges comprising an axially extending peak portion disposed between the central area and the periphery,
- wherein the cutting edges comprise an undercut face below the flat zone, the undercut face being disposed at a non-zero angle relative to the reference plane parallel to the axis of rotation of the cutting head.
A method of milling a workpiece, the method comprising:
- rotating a mill about an axis;
- and
- removing material from the workpiece with cutting edges of top teeth of the mill, the cutting edges extending from a central area of the top region towards a periphery of the top region, wherein each the cutting edge defines a spoke axis which forms a non-zero angle relative to a reference radial line extending from the center of the top region, the spoke axis intersecting the reference radial line at the periphery,
- wherein the cutting edges-comprise an undercut face below the flat zone, the undercut face being disposed at a non-zero angle relative to the reference plane parallel to the axis of rotation of the cutting head.
