Análise de falha durante o processo de conformação de folhas de aço para trinchas

Abstract

Any production process is subject to the most diverse types of failures, which can generate from small reworks to very serious accidents. This work used the FMEA methodology to survey the failure modes present during the mechanical forming process of a tinned steel strip for the manufacture of a component of the painting brush fabrication line. For this, the supply of feedstock was analyzed, performing a bending test to compare batches of material received. It was also evaluated the bending steps and the impacts of the adjustments during the setups of the machines and their sets of tools for the bending process. With this study, we can verify that the state of conservation of the tools and the adjustments made during the setups of the machines are crucial parts in the prevention and control of failures.
