Objectification of FMEA method parameters and their implementation on production engineering

Marián Bujna , Paweł Kiełbasa


We applied the conventional PFMEA (process Failure mode and effect analysis) and identified the RPN risk number on production engineering (the work process on the lathe). Then we added the costs of failures to the method and applied Extended FMEA. After determining the costs and calculations, we identified the ERPN (extended risk priority number). We compared the individual methods and we also compared the proportion of failures in total risk generation (RPN - ERPN). We proposed an action. Finally, we evaluated the applicability of individual methods and models. The ERPN, in contrast to the conventional PFMEA, specifies the risk number. After including the costs necessary for elimination of the failures and costs arising from failures, we have obtained another risk prioritization. The use of the economic effect of the FMEA brings not only an increase in the quality and reduction of defective products, but also the influence of the financial costs on the creation of the risk number.
