Abstract

The invention relates to a method for machining a surface of a metal workpiece (20) using a turning tool (10) comprising a tool body and a first cutting insert (1) arranged at a front end (8) of the tool body, wherein the method comprises:- a first entering step (31) in which the turning tool (10) is moved towards a first end (41) of a longitudinal portion (21) of the workpiece along a first entering path (L1) that is transverse to both a longitudinal direction (Z) and a radial direction (X), such that the first cutting insert (1) cuts chips from the longitudinal portion (21) of the metal workpiece (20) at an entering angle (E1) of a first cutting edge (2) of the first cutting insert of 60°-120°; and- a longitudinal turning step (36) in which the turning tool (10) is moved along the longitudinal direction (Z) away from the first end (41) and towards a second end (42) of the longitudinal portion (21) such that the first cutting insert (1) cuts chips from the longitudinal portion (21) of the metal workpiece (20) at an entering angle (E2) of a second cutting edge (3) of the first cutting insert of 10°- 45°.
