Process failure modes and effects analysis (PFMEA): A structured approach for quality improvement in the metal forming industry
- 503 Downloads
Failure modes and effects analysis (FMEA) is one potential tool with extended use in reliability engineering for the electrical and electronic components production field as well as in complicated assemblies (aerospace and automotive industries). The main purpose is to reveal system weaknesses and thereby minimize the risk of failure occurrence. The FMEA technique is used in the design stage of a system or product (DFMEA) as well as in the manufacturing process (PFMEA). Currently, the implementation of quality systems (such as ISO 9001, QS9000, TS 16949, etc.) requires the establishment of preventive procedures; therefore, the use of risk analysis methods, such as FMEA, is mandatory. This paper introduces the use of this technique in a critical process in the metal forming industry.
