Abstract

A method for determination of an effective machine use of a machine tool, as well as a machine tool that is configured for this purpose. The machine tool has multiple machine axes in order to move a workpiece and/or a tool. A rotary drive drives the workpiece or the tool in order to remove material. A control unit of the machine tool determines a use duration characteristic parameter (T) and an output power characteristic parameter (L) and determines therefrom a machine use characteristic parameter (M). The use duration characteristic parameter (T) describes a duration during which the workpiece is machined by the tool. The output power characteristic parameter (L) describes the applied or required power in order to effect the material removal. The machine use characteristic parameter (M) is determined by the control unit, such that it can be transmitted to an external unit for further evaluation or processing.
