WITHDRAWN: Failure analysis of tyre production process using FMECA method

Abstract

Abstract This paper presents a failure analysis of real industry case using FMECA method. The case study is conducted in a tyre manufacturing industry focusing on the machine components mechanism failures. Field failures record data are systematically analyzed to identify and classify the failure modes, effects and determined the criticality index on the subject under study. The details of step-by-step in applying FMECA according to the case study, the resultsand discussion have been presented accordingly. It is then concluded and proved that the FMECA method is beneficial to rank and prioritize failures systematically and thus help engineering team to perform the improvement project based on the right problem. Keywords : Failure analysis, Industry case study, Failure Mode Effect and Criticality Analysis (FMECA) 1. Introduction Every machine and process in daily manufacturing operations has it owns modes of failure. These modes of failures are where the state of termination of the ability of an item of any part, component, device, subsystem, functional unit, component or system that can be individually considered, to perform a required function takes in place as per definition by SS-EN 13306 [1]. In short, there are two types of failure which are the functional failure and the potential failure. A functional failure is the inability of an item or the component containing itto meet a specified performance standard meanwhile the potential failure is an identifiable physical condition which indicates a functional failure is imminent by referring to Nowlan and Heap [2].
