Abstract(s)
Na Ćŗltima dĆ©cada foi observado nas indĆŗstrias a tendĆŖncia de reduĆ§Ć£o do tempo
de setup das diversas mĆ”quinas presentes nas mesmas. A empresa Ricardo & Barbosa ā
empresa onde se fabricam ferramentas e moldes para peƧas do setor automĆ³vel,
energĆ©tico, eletrĆ³nico e ainda, maisrecentemente, aeroespacial ā foi uma das empresas
impactadas por esta tendĆŖncia. PorĆ©m, existiam algumas mĆ”quinas em que esta
reduĆ§Ć£o de tempo de setup ainda nĆ£o tinha sido pensada. Neste caso de estudo foi
implementado um mĆ©todo associado Ć filosofia Lean: Single Minute Exchange of Die
(SMED). O SMED foi aplicado ao serrote para corte de matƩrias-primas presente no
armazĆ©m da empresa. A implementaĆ§Ć£o desta metodologia culminou numa reduĆ§Ć£o
aproximada de tempo de setup da mƔquina em cerca de 43%.
A metodologia usada na recolha de dados foi a metodologia investigaĆ§Ć£o-aĆ§Ć£o,
que serĆ” posteriormente explicada.
De modo a relacionar a implementaĆ§Ć£o do SMED na empresa com o aumento da
sustentabilidade da mesma, foram estudados os diversos impactos nos 3 pilares da
sustentabilidade: econĆ³mica, social e ambiental, sendo esses impactos calculados para
antes e apĆ³s a implementaĆ§Ć£o da metodologia SMED.
Os resultados que foram obtidos permitem concluir que a metodologia impactou
positivamente e negativamente esses 3 indicadores de sustentabilidade na secĆ§Ć£o em
questĆ£o, tudo isto devido Ć reduĆ§Ć£o de tempo de setup
In the last decade, industry businesses have shown a tendency for reducing their machineās setup time. The company Ricardo & Barbosa LDA. ā company that is specialized in making specific molds and tools for the automotive sector, as well as energetic, electronic or, more recently, aerospace ā was one of the businesses that was impacted by this tendency. However, there were some machines where this reduction of setup time wasnāt implemented yet. In this case study, one method of the lean philosophy was implemented: the method Single Minute of Exchange of Die (SMED). SMED was implemented into the semiautomatic bandsaw machine placed in the companyās warehouse that is used to cut raw materials. The implementation of this methodology has made approximately 43% in reduction of setup time. To connect the implementation of SMED with sustainability, there were studied all of the impacts in the 3 main sustainabilityās indicators: economic sustainability, social sustainability and environmentalsustainability, being thisimpacts calculated before and after the implementation of this methodology. The obtained results make us conclude that in this machine this methodology has impacted both positively and negatively those 3 indicators of sustainability, all of that due to the decrease of setup time
