Abstract(s)
As organizações, encontram-se cada vez mais em busca da perfeição e na melhoria de incrementos de produtividade e qualidade dos seus produtos, promovendo uma maior competitividade no mercado. A competência para satisfazer os clientes, reduzindo o desperdício associado ao chão de fábrica, é diretamente proporcional à qualidade de uma organização. Um dos principais ramos na indústria que tende a ser exigente nos mercados globais e que se encontram em constante evolução, capazes de apresentar uma maior resposta a nível de excelência na produção, é o ramo automóvel. O presente trabalho foi desenvolvido na FicoCables, empresa que se dedica à produção de componentes automóveis. Este estudo teve como finalidade a otimização da qualidade da espiral nas máquinas de corte, pois produziam grande quantidade de produto não conforme, devido à falta de precisão no processo. Assim, o objetivo deste projeto era reduzir o número de boletins não conformes, isto é, a quantidade de espirais que se encontra fora do limite de especificação, analisando a situação atual e desenvolvendo ações de melhoria. A metodologia utilizada na resolução deste problema foi o Lean Six Sigma, onde se utilizou o ciclo DMAIC (Define, Measure, Analyze, Improve, Control). Após chegar à conclusão das causas-raiz que contribuem para a falta de precisão no processo de corte da espiral, foram definidas e implementadas ações de melhoria. Com as ações implementadas, obteve-se um ganho mensal de 1744,52€, tendo sido melhorada a estabilidade do processo, a qualidade da espiral, e a produtividade, promovendo uma redução do número de boletins não conformes.
Organizations are increasingly seeking perfection in improving the productivity and quality of their products, promoting competitiveness in the marketplace. The competence to satisfy customers by reducing the waste associated with the shop floor is directly proportional to the quality of an organization. One of the main branches in the industry that tends to be demanding in global markets and that are in constant evolution, capable of presenting a greater response at the level of excellence in production, is the automotive branch. The present work was developed at FicoCables, a company engaged in the production of automotive components. The purpose of this study was to optimize the quality of the spiral on the cutting machines, as they were producing a large amount of nonconforming product due to the lack of precision in the process. Thus, the goal of this project was to reduce the number of non-compliant bulletins, i.e., the number of spirals that are outside the specification limit, by analyzing the current situation and developing improvement actions. The methodology used to solve this problem was Lean Six Sigma, where the DMAIC (Define, Measure, Analyze, Improve, Control) cycle was used. After being aware of the root causes contributing to the lack of accuracy in the spiral cutting process, improvement actions were defined and implemented. With the implemented actions, a monthly save of 1744.52€ was obtained, where the stability of the process, the quality of the spiral, and productivity were improved, reducing the number of non-conforming bulletins.
