Process for monitoring processing plants

Abstract

A method of monitoring and/or controlling machining plans having time-dependent machining parameters includes measuring desired time-dependent machining parameters as a measured curve, generating time-independent numerical values from the measured machining parameters, and entering the time-independent numerical values into a classifier distinguishing between normal states of the machining plant and abnormal states of the machining plant. Training vectors regarded as abnormal can be filtered out from training vectors available by determining a distance of each training vector from every other training vector with a selected measure of distance for filtering of the abnormal training vectors, the training vectors having components made of time-independent numerical values, and the classifier can be trained with training vectors.
