ABSTRACT:
The invention relates to the cutting of rotating surfaces, especially centric symmetric surfaces (1a) of a metal workpiece (1), especially one made of steel or gray cast iron, also when said workpiece is in hardened state, by means of a geometrically determined cutter (2a) or cutters, wherein the axial extension and the material of the surface to be machined are hardly limited or not limited at all and/or the operating time during machining is reduced according to said method and/or the service life of the tool is enhanced and/or the effect of the twist-free condition is achieved, wherein at least one cutter (2a) that is skewed relative to the rotational axis (10) of the workpiece is guided during a feeding motion (3,3′) in a contacting manner on the rotating workpiece and wherein the machining parameters of the rotational axis, especially the forward feed motion in the direction of feeding and the skewed position (x) of the cutter (2a) relative to the longitudinal direction (z), are chosen in such a way that twisting in terms of the degree of twisting (s) and/or the depth of twisting (t), more particularly the depth of twisting, on the surface being machined is minimized, wherein the forward feed motion includes an axial movement.
