Many different surface defects are difficult to classify for a machine operator. These include black dots, specks, holes and folds.
With the help of an assessment of the overall quality, taking into account different customer specifications, the decision for the worker can be simplified and even accepted. Errors are reduced and confidence in the processes is improved.
A rating system calculates the defects occurring according to frequency, severity and position and builds a grade based on them. (School grading system) If this evaluation is coupled with the local operating systems, the production goods can be automatically blocked in the MES.
