Abstract
A turning method for a computerized numerical control lathe includes providing a turning tool having a cutting portion, the cutting portion including a first nose portion, the first nose portion including a first cutting edge, a second cutting edge, and a convex nose cutting edge connecting the first and second cutting edges, wherein the first and second cutting edges are straight or substantially straight in a top view. The method further includes providing a metal work piece, rotating the metal work piece around a work piece rotational axis, and making a first pass where the first cutting edge is active and the second cutting edge is inactive. A first machined surface is generated by the convex nose cutting edge, and during at least a portion of the first pass, an entering angle and an angle, which the first cutting edge forms with the work piece rotational axis, simultaneously varies.
