Abstract
A method for machining a workpiece is provided, wherein drilling of the workpiece and subsequent countersinking of the bore, obtained by the drilling, in the workpiece are performed by means of a drilling/countersinking tool in a machining process, wherein the drilling/countersinking tool in the machining process while being axially rotated is subjected to an axial feed movement relative to the workpiece that reaches a counterbore terminal position, and wherein the axial feed movement is superimposed by an axial vibration, wherein, when reaching a predefined frequency lowering position of the axial feed movement by the drilling/countersinking tool, the frequency of the axial vibration is lowered to a final machining frequency, and the machining process is continued at the final machining frequency as the maximum frequency of the axial vibration until the counterbore terminal position is reached.
