METHOD FOR DETERMINING A PROPERTY OF A MACHINE, IN PARTICULAR A MACHINE TOOL, WITHOUT METROLOGICALLY CAPTURING THE PROPERTY
A computer-implemented method determines a property of a machine, in particular a machine tool, without metrologically capturing the property. The method includes the following steps: capturing one or more first time series of one or more physical measurement variables of the machine; detecting change points in the one or more first time series; extracting pattern-sequence instances from the first time series on the basis of the detected change points; producing a plurality of pattern-sequence classes in accordance with the extracted pattern-sequence instances; identifying at least one characteristic of a plurality of pattern-sequence instances of the same pattern-sequence class and a time curve of the characteristic; determining a property of a machine using the determined characteristic and/or using the time curve of the determined characteristic.
