1. A pulse laser assisted machining method comprising a fine machining process, said fine machining process comprising the following steps of:

  • (a)focusing a laser beam in such a manner that a focal point is located on a workpiece, and that the focal point is separated from a front of the blade of a machinning tool by a microdistance;

    (b) moving the workpiece and the machining tool in relation to each other;

    (c)softening a focused area by an instantaneous laser heating;

    (d)advancing the machinning tool such that the machined material and the softened material are removed together, and that the same machinning mechanism is repeated until a subsequent laser emission.
