Abstract

This study presents the Failure Modes and Effects Analysis (FMEA) is a systematic approach that identifies potential failure modes in a manufacturing and final assembly operation caused by manufacturing process deficiencies. The FMEA also is a tool used to prevent problems from occurring. The FMEA is a methodology used by the manufacturing industries to analyze and discover all potential failure modes of a process function, identify the effects these failures on the process and how to correct and mitigate the failures or effects on the process. The Process FMEA is applied on manufacturing processes in the industry i.e. foot switches to reduce the failure modes and preparing the preventions and recommended actions to reduce the failure as much as possible, reduce costs and improving the product quality. The study discusses steps to conduct the Process FMEA methodology. The research by observation and collect data of failures occurred at the paint line and final assembly section in the manufacturing processes. The Risk Priority Number (RPN) is calculated with a suggested severity, occurrence and detection evaluation criteria table provided as a guide to find the ranking for the failures occurs. The discussion regarding the results and how to improve the failures with the recommended actions is given. These actions are meant to reduce the Risk Priority Number (RPN), so that the method of Process Failure Mode and Effects Analysis (PFMEA) is effective to use for this foot switches manufacturing processes. To surpass the expectations or demands of customers, the FMEA is compulsory to apply on the products and manufacturing processes and also the PFMEA brings more benefits to the customers and organizations.
