Dyagnosis System for the Elimination the Observed Faults During Deep Drawing

In this paper the use of fuzzy system modeling in expert system for the purpose of detection and elimination of faults in the technology of deep drawing is considered. The evaluation function estimates the possible causes of the faults and suggests actions taking into account the folowing criteria: the product price, time of use, level of disturbing technological process, and standardisation of tool parts and technological parameters. The expert system can eliminate the observed faults in three groups of actions. The actions can be related to workpiece material, tool, technological parameters, and to their interactions.
