1. A method for machining a workpiece using a milling tool, wherein the milling tool engages with the workpiece and a cutting motion is induced between the milling tool and the workpiece, whereina relative first vibration motion between the workpiece and the milling tool, which is superimposed on the cutting motion, is induced in such a way that one or more characteristic values of the first vibration motion and one or more characteristic values of the cutting motion are set related to one another, andwherein parameters are defined to satisfy one or more of the following equations:


  • fv=vs/lw
    φ

    =k5*π

    wherein fv is a vibration frequency of the first vibration motion,vs is a feed rate of a cutting edge on a workpiece surface,lw is a wavelength of a pattern of the first vibration motion, which is formed on the workpiece surface,φ

    is a phase displacement in a feed direction of the cutting edge between several pairs of patterns in adjacent milled tracks, andk5 is a factor ranging from −

    1 to 1.
