ABSTRACT:
A crankshaft (6) is rotated about its axis (7), and all of its crankpins (28, 29, 30), which each respectively have an eccentricity (e) relative to the axis (7), are simultaneously rotary milled by respective allocated rotary milling cutters (34, 35, 36) of a milling cutter set (12). The individual milling cutters (34, 35, 36) each respectively have an eccentricity (e) corresponding to the eccentricity of the respective crankpin that is allocated to be machined by the respective milling cutter. Furthermore, the milling cutter set (12) is rotated at the same rotational speed, i.e. with a rotational speed ratio of 1:1, relative to the rotating crankshaft, while simultaneously the milling cutter set is moved in the X-direction toward the crank-shaft axis to achieve a feed advance. A rotary milling machine for carrying out the method includes a milling cutter set of which the milling cutters respectively have the same eccentricity as the respective allocated crankpins of the crankshaft to be milled, and includes a drive apparatus for achieving the 1:1 rotation of the milling cutter set relative to the crankshaft as well as the feed advance motion of the milling cutter set. In this manner, the milling cutters automatically follow the eccentricity of the crankpins, without requiring a complicated individual guidance.
