For an improved management of machining information, esp. for a facilitated determination of step features from a sample machining process, a computer-implemented method is suggested comprising: providing a sample machining process for machining a sample workpiece from a sample blank, the sample machining process comprising at least two consecutive sample machining steps performed by the respective tool starting with a respective sample start part and ending with a respective sample end part, wherein the respective sample end part of the respective sample machining step is the respective sample start part of the respective subsequent sample machining step; determining a respective step tool volume corresponding to a movement of the respective tool during the respective sample machining step; determining a respective step volume corresponding to the respective sample start part of the respective sample machining step changed by the respective step tool volume; determining at least one respective step feature corresponding to the respective step volume; and storing the respective step feature in a machining information database.
