Typical manufacturing errors often become noticeable by identical or very similar changes in the measurement signals. If the changes in the signal curves to be monitored for certain errors are known, these can be stored as a sample in the software. The process monitoring system responds immediately when it recognizes the pattern again, and notifies the machine operator of the detected error type. The special advantage of stored sample curves is that the recognition works independently of the set envelopes. This can reliably detect the errors even in case of coarse envelope settings.
