Abstract
A milling tool for face milling includes a tool body and a plurality of cutting members arranged successively along a periphery of the tool body. Each cutting member includes a main cutting edge provided for a roughing operation and a subset having a first, a second and a third secondary cutting edge provided for a finishing operation. The first and third secondary cutting edges extend in a direction perpendicular to an axial direction and the second secondary cutting edge extends between the first and third secondary cutting edge. The main cutting edges are situated at the same radial position and the first secondary cutting edges are situated at the same axial position. A first end point of the second secondary cutting edges successively progress radially inward and a second end point of the second secondary cutting edges successively progress radially inward and axially outward along the periphery of the tool body.
