A computer-implemented method for determining a property of a machine, in particular a machine tool, without metrologically capturing the property, comprising: - capturing of one or more first time series of one or more physical measurement variables of the machine; characterised by the further method steps: - detecting changing points in the one or more first time series; - extracting pattern-sequence instances from the first time series on the basis of the detected changing points; - producing a plurality of pattern-sequence classes in accordance with the extracted pattern-sequence instances, wherein the pattern-sequence classes each comprise a plurality of pattern-sequence instances having a certain commonality; - ascertaining 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 ascertained characteristic and/or using the time curve of the ascertained characteristic; wherein one of the following method steps is carried out after the production of the pattern-sequence classes: - assigning the pattern-sequence classes to operating states of the machine and/or a component of the machine and/or a tool of the machine according to operating state information provided by a control unit of the machine; or - assigning the pattern-sequence classes to operating states of the machine and/or a component of the machine and/or a tool of the machine according to operating state information provided by an operator of the machine or a system which is superordinate to the machine, such that a pattern-sequence class is selected which is assigned to an operating state which is characteristic of the property of the machine to be determined. - capturing of one or more first time series of one or more physical measurement variables of the machine; characterised by the further method steps: - detecting changing points in the one or more first time series; - extracting pattern-sequence instances from the first time series on the basis of the detected changing points; - producing a plurality of pattern-sequence classes in accordance with the extracted pattern-sequence instances, wherein the pattern-sequence classes each comprise a plurality of pattern-sequence instances having a certain commonality; - ascertaining 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 ascertained characteristic and/or using the time curve of the ascertained characteristic; - detecting changing points in the one or more first time series; - extracting pattern-sequence instances from the first time series on the basis of the detected changing points; - producing a plurality of pattern-sequence classes in accordance with the extracted pattern-sequence instances, wherein the pattern-sequence classes each comprise a plurality of pattern-sequence instances having a certain commonality; - ascertaining 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 ascertained characteristic and/or using the time curve of the ascertained characteristic; wherein one of the following method steps is carried out after the production of the pattern-sequence classes: - assigning the pattern-sequence classes to operating states of the machine and/or a component of the machine and/or a tool of the machine according to operating state information provided by a control unit of the machine; or - assigning the pattern-sequence classes to operating states of the machine and/or a component of the machine and/or a tool of the machine according to operating state information provided by an operator of the machine or a system which is superordinate to the machine, - assigning the pattern-sequence classes to operating states of the machine and/or a component of the machine and/or a tool of the machine according to operating state information provided by a control unit of the machine; or - assigning the pattern-sequence classes to operating states of the machine and/or a component of the machine and/or a tool of the machine according to operating state information provided by an operator of the machine or a system which is superordinate to the machine, such that a pattern-sequence class is selected which is assigned to an operating state which is characteristic of the property of the machine to be determined.
