Este artigo aborda a metodologia Single Minute Exchange of Die (SMED), tambĆ©m conhecida por troca rĆ”pida de ferramentas (TRF) que visa reduzir o tempo de set-up das mĆ”quinas numa unidade fabril, com vista Ć reduĆ§Ć£o do lead time de produĆ§Ć£o. A reduĆ§Ć£o do lead time permite uma maior flexibilidade, qualidade e produtividade operacional. Para o efeito utilizou-se a metodologia de estudo de caso numa fĆ”brica de componentes automĆ³vel, em que se monitorizou a evoluĆ§Ć£o dos resultados operacionais, com a implementaĆ§Ć£o desta ferramenta. Assim, o objetivo deste trabalho Ć© analisar se a utilizaĆ§Ć£o da metodologia SMED, reduz o tempo de set-up e o lead time de produĆ§Ć£o. Os resultados permitem concluir que a implementaĆ§Ć£o do SMED contribui para melhorias significativas no setor em anĆ”lise: reduz o tempo de set-up, o stock de peƧas, o nĆŗmero de mĆ”quinas utilizadas e os operadores necessĆ”rios, permitindo com estas reduƧƵes ganhos de produtividade significativos.
This article addresses the Single Minute Exchange of Die methodology (SMED), which aims at the decrease in machineās changeover time of the factory to achieve the shorten of production lead time. The reduction of lead time production allows more flexibility, quality, and operational productivity. For this purpose, a case study methodology was selected in components automotive factory. The evolution of operational results caused by this tool implementation were monitored. Thus, the goal of this work is to analyze whether the implementation of this methodology decreases machineās changeover time and shorten production lead time. The results allow us to conclude that the implementation of SMED contributes to significant improvements in the sector under analysis: it reduces the set-up time, the stock of pieces, the number of machines used and the number of operators needed, allowing with these reductions, significant productivity gains.
