Abstract

The present invention relates to a turning method for machining a metal workpiece with a turning tool comprising a cutting edge, which cutting edge includes a cutting nose and a clearance corner, wherein the method comprises the steps of: - determining a final machined profile of the metal workpiece, wherein the final machined profile comprises a main surface and a shoulder surface; - determining a cutting depth; - rotating the metal workpiece around an axis of rotation; - cutting the metal workpiece with the cutting nose by, - a) moving, at the cutting depth, the cutting nose along the main surface, towards the shoulder surface, - b) moving the cutting nose further toward the shoulder surface until the clearance corner is positioned on the shoulder surface, - c) moving the cutting nose away from the shoulder surface, - d) moving the cutting nose toward the shoulder surface until the clearance corner is positioned on the shoulder surface, - e) moving the cutting nose away from the shoulder surface, wherein any of the steps b - e comprises moving the cutting nose towards the main surface, - f) moving, at the cutting depth, the cutting nose along the main surface, further away from the shoulder surface.
