METHOD FOR DETERMINING A PROPERTY OF A MACHINE, IN PARTICULAR A MACHINE TOOL, WITHOUT METROLOGICALLY CAPTURING THE PROPERTY

摘要

The invention relates to a computer-implemented method for determining a property of a machine, in particular a machine tool, without metrologically capturing the property, comprising the following method 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.
