1. A method for vibration or sound analysis of a component to determine if said component is properly working or if a part is properly formed by use of said component, in which vibrations or sounds occurring by one or more operations selected from the group consisting of a) use of said component and b) testing of said component, said component included in a workpiece used for chipping, welding, forming, joining, separating or combinations thereof, said vibrations or sounds are registered and evaluated, wherein a vibration spectrum using said vibrations or sounds is recorded at different times or (quasi-) continuously to create multi-dimensional data based on at least two dimensions selected from the group consisting of time, vibration or sound frequency and vibration or sound amplitude, said multi-dimensional data is subjected to a multi-dimensional evaluation, said multi-dimensional evaluation including a comparison of said multi-dimensional data to reference data to determine deviations between said multi-dimensional data and said reference data.
