1. A method for turning a workpiece with a tool system having an interchangeable cutting insert disposed on an end face of a tool body in a rotationally fixed manner in such a way that an upper side of the interchangeable cutting insert configured as a rake face is oriented perpendicularly to a longitudinal axis of the tool body, and a cutting edge formed between the upper side and a peripheral lateral face of the interchangeable cutting insert projects in a radial direction with respect to the longitudinal axis beyond an outer circumference of the end face of the tool body by way of at least two usable cutting corners and cutting edge portions adjoining the at least two usable cutting corners on both sides, the method comprises the following steps of:
rotating the workpiece about a workpiece axis;
machining a surface of the workpiece with a first cutting corner in such a way that chips generated run off on the upper side of the interchangeable cutting insert; and
changing a chip formation by controlled rotation of the tool body about the longitudinal axis and translational movement, coordinated therewith, of the tool body in a plane, which runs perpendicularly to the longitudinal axis, with a translational movement component perpendicular to the workpiece axis, whereby instead of the first cutting corner, a second cutting corner of the interchangeable cutting insert is now brought into an active cutting position.
