Abstract (en)

[origin: WO2015197448A1] In a method for finish machining of peripheral surfaces of rotationally symmetrical workpiece sections on workpieces, a finishing tool (100) comprising a pressing force in a pressing direction (AR) is pressed on the peripheral surface to be machined when a peripheral surface is machined. In order to produce material removal, the workpiece is rotated about a workpiece axis (192) and an oscillating relative movement is produced between the finishing tool and the workpiece In order to produce the oscillating relative movement, the finishing tool is moved back and forth along an oscillation direction with a predeterminable oscillation stroke length and oscillation frequency. A linear movement of the finishing tool running parallel to the workpiece axis is superimposed on the oscillation movement over a linear stroke length. A pivoting movement of the finishing tool about a pivot axis running perpendicular to the workpiece axis and to the pressing direction is superimposed on the linear movement and oscillation movement. A pivot position of the finishing tool is controlled in relation to the axial position of the linear movement. In this way, different axial surface line profiles can be produced in a targeted manner by means of finishing in order, for instance, to obtain a convex shape of the workpiece sections.
