Aplicação do FMEA para proposição de melhorias na gestão da manutenção de uma indústria têxtil.

Abstract

With the high competitiveness in the textile sector, the availability and reliability of machinery has become increasingly essential for companies to beat all their production and sales targets. An unexpected downtime of a certain machinery can lead to several problems, if the maintenance team doesn't have a planned for this type of occurrence, such as loss of productivity and increase in maintenance cost. Faced with this, this study seeks to apply FMEA (Failure Mode and Effect Analysis) – AMFE (Análise do Modo de Falhas e Efeito) in the production process of yarn manufacturing in a textile company, in order to elaborate an action plan that can reduce unscheduled maintenance stoppages. For this, a review of the main maintenance concepts was performed, as well as some tools used to achieve improvements in its management. Then, observations were made in the production lines in order to identify the most critical equipment, the failures related to it and the frequency with which they happen. After the application of FMEA, the tool and 5 Why was used to discover the root causes that led to the failures pointed out. Based on the results obtained with the application of these tools it was possible to propose maintenance actions to correct the most frequent failures of the machinery under analysis.
