Abstract

A method for forming a thread with a predefined thread pitch and with a predefined thread profile in a workpiece, in which a tool is used, wherein, during working movement, a thread generating region forms a thread, wherein the tool is moved during a second working phase further into the workpiece in the same forwards direction as in the working movement, as far as a reversal point, wherein the decelerating movement comprises a rotational movement in the same rotational direction as in the working movement, wherein during the decelerating movement, the axial feed movement is controlled in dependence on the rotational angle of the rotational movement of the tool and wherein the axial feed of the tool during a complete revolution, is smaller in terms of amount than the thread pitchat least during part of the decelerating movement and is zero at the reversal point.
