Abstract: The invention relates to a method for machining a workpiece, comprising the following steps: providing, in a receiving portion of a numerically-controlled machine tool, a measuring probe that comprises a stylus, said measuring probe being configured to emit an output signal that is at least partially and at least approximately proportional to a deflection of its stylus, and the progression of said output signal at least approximately reproducing a contour of a workpiece; determining, in a preparation phase, at least one correction function for at least one section of the output signals relating to the associated deflection of the measurement probe stylus; storing characteristic variables of said at least one correction function in the measurement probe or a machine control unit associated with the machine tool; at least partially continuously tracing the contour, in a tracing phase, of a workpiece clamped in the machine tool but not yet fully machined, using the stylus of the measurement probe provided in the receiving portion of the machine tool; correcting the output signal of the measurement probe using the characteristic variables of the correction function; supplying the corrected output data to the machine control unit associated with the machine tool; calculating the corrected output data with machine coordinates of the contour to be produced, for machining the workpiece clamped in the machine tool, such that control commands for the machine tool are received; and machining the workpiece clamped in the machine tool using a tool that is provided in the receiving portion of the machine tool.
