Method and device for machining a workpiece by cutting or upsetting using at least one tool (67), wherein the workpiece or each tool is rotated about an axis. Each tool (67) is moved longitudinally along an axis parallel to the rotational axis, each tool (67) is simultaneously and transversely moved along an axis orthogonal to the rotational axis, and the workpiece and each tool (67) are translated in relation to each other along an axis parallel to the rotational axis, in combination with said longitudinal and transverse movements, so that one of them is axially reciprocated over a variable amplitude range and synchronised with the rotation of the workpiece.
