The invention relates to a method for automatically optimizing material removal during cutting of a workpiece (1) with the aid of a numerically controlled (NC) machine tool. According to said method, the tool (2) is moved relative to the workpiece along tool paths, a control unit precalculates a machining simulation by means of a workpiece model, at least one NC command is executed in the simulation before being actually executed while the removal of material is determined by said NC command, the calculated material removal is compared to a predefined threshold value, the NC command is corrected if said threshold value is exceeded, and the program is executed with a corrected NC command to introduce a secondary tool path (4) such that less material is removed. |
