Abstract(s)
Atualmente, as empresas têm vindo a enfrentar períodos cada vez mais desafiantes. Devido à notória globalização de mercados, alterações de padrões de consumo dos clientes e maiores exigências de clientes existe a necessidade das indústrias de inovar constantemente e ter um foco incessante na melhoria da qualidade dos seus processos. Verifica-se que cada vez mais empresas têm vindo a recorrer a filosofias de ProblemSolving com o objetivo de melhorar a qualidade dos seus processos e produtos. A filosofia Six-Sigma é um exemplo de filosofias de Problem- Solving. O presente caso de estudo foi desenvolvido em ambiente industrial, no grupo empresarial WEG S.A. O objetivo do caso de estudo foi o aumento da vida útil de uma ferramenta utilizada na indústria de motores elétricos através da aplicação da filosofia Six-Sigma. Implementou-se a abordagem DMAIC que permitiu a utilização de várias ferramentas e técnicas da qualidade e da estatística. Na abordagem referida, foram efetuadas três análises a sistemas de medição, uma análise DOE e foi incorporada uma análise de elementos finitos. Foram estudadas e testadas várias sugestões de melhoria. Foi criado um plano de implementação composto pela alteração da ferramenta de inserção de estatores. A nova ferramenta, através da análise FEA, mostrou-se mais robusta e capaz de garantir o aumento da sua vida útil.
Nowadays, companies are facing increasingly challenging periods. Due to the notorious markets globalization, changes in customer consumption patterns and greater customer demands, there is a need for industries to constantly innovate and have a relentless focus on improving the quality of their processes. It appears that more and more companies have been using Problem Solving methodologies with the aim of improving the quality of their processes and products. The Six-Sigma methodology is an example of ProblemSolving methodologies. The present case study was developed in an industrial environment, in WEG S.A. group. The objective of the case study was to increase the useful life of a tool used in the electric motors industry through the application of the Six-Sigma methodology. The DMAIC approach was implemented, which allowed the use of various quality and statistical tools and techniques. In the referred approach, three analyses of measurement systems were carried out, a DOE analysis and a finite element analysis was incorporated. An implementation plan was defined, comprising the alteration of the stator insertion tool. The improved tool, through FEA analysis, proved to be more robust and capable of guaranteeing an increase in its useful life.
