FMEA: Methodology, Design and Implementation in a Foundry

Abstract

Failure Mode And Effect Analysis (FMEA) is a technique to identify and prioritize potential failures of a process. This paper reports the description of FMEA methodology & its implementation in a foundry. It is used as a tool to assure products quality & as a mean to improve operational performance of the process. The work was developed in an Indian foundry, in co-operation with part of the internal staff chosen as FMEA team members & was focused on the study of core making process. The problems identified in the various steps of core making process contributing for high rejection are studied & analyzed in terms of RPN to prioritize the attention for each of the problem. The monetary loss due to core rejection is considered as measure of risk.
