Abstract
In a method for machining a workpiece with a machining system, the machining system is controlled with at least one control parameter, which is then adapted during machining of the workpiece based on an instantaneous mass of the workpiece or based on an instantaneous moment of inertia of the workpiece. The instantaneous mass of the workpiece or the instantaneous moment of inertia of the workpiece are dependent on a machining progress and are ascertained with reference to a geometric model of the workpiece to be machined based on a density of the workpiece and an instantaneous shape of the workpiece as determined with reference to the geometric model of the workpiece. The geometric model is updated with reference to a machining simulation.
