Uso da engenharia de processos e ferramentas Lean Six Sigma na melhoria dos resultados do setor de produção de uma fábrica de peças mecânicas ferroviárias

Abstract

This research aims to perform a case study analysis a company specialized in railway parts, components and services for locomotives and freight cars. It is intended to analyze your production process, identify the most problematic item and improve its results through the application of continuous improvement tools Lean Six Sigma. For this, the DMAIC tool will be used (define, measure, analyze, improve and control). In the measurement phase, the parts that presented the most problems were listed and in the next stage it was understood that the central cause of all failures could be related to the cast raw material used for the manufacture of a part called T-pin. Thus, this manufacturing process, replacing the casting method by the forging method. Finally it was found that with this change in the manufacture of raw material was possible to reduce the production time in the factory, meet the promised time to the customer and improve the quality of the parts produced.
