O presente trabalho integra a unidade curricular Dissertação/Projeto/Estágio do Mestrado em Engenharia Mecânica, ramo Materiais e Tecnologias de Fabrico, do Instituto Superior de Engenharia do Porto concebido em ambiente empresarial na Siemens Gamesa Renewable Energy Blades, empresa produtora de pás para turbinas eólicas. Da necessidade de as empresas serem cada vez mais competitivas e eficientes surge uma busca insaciável pela melhoria contínua, permitindo às que aplicam esta ideologia uma redução de tempos de produção, melhores formas de realizar operações, reduções de custos/materiais e melhores condições de trabalho para os seus colaboradores, refinando ou mantendo a qualidade dos seus produtos. A presente dissertação tem como principal objetivo analisar o impacto do uso de ferramentas Lean numa indústria de compósitos, mais concretamente no fabrico de uma pá eólica implementada, recentemente, na fábrica. A análise inicial consistiu em encontrar possíveis falhas e melhorias, seguida da medição dos ganhos expectáveis, teste das resoluções, avaliação das medidas, decisão da implementação ou não e, por fim, a atualização da documentação referente ao projeto. Na busca do aperfeiçoamento do projeto foi realizada uma pesquisa relativa à metodologia Lean e a ferramentas, como Standard Work, 5S, BoM, Gestão Visual, KPI, para auxiliar o cumprimento do objetivo pretendido. A utilização de ferramentas Lean permitiu reduzir e eliminar quantidades excessivas de materiais usados no processo de fabrico, garantir a robustez na execução de tarefas bem como reduzir o tempo de execução de operações: 70% na tarefa calibração, 75% na montagem de pernos, 85% na criação e atualização de Standard Works e de 99% na marcação da posição de componentes aerodinâmicos na pá.
The following essay is presented as part of the course unit of Dissertation/Project/Internship of the Master’s in Mechanical Engineering, in the field of Material and Manufacturing Technologies, of Instituto Superior de Engenharia do Porto. This project was designed in a business-like environment at Siemens Gamesa Renewable Energy Blades, a company which produces blades for wind turbines. Due to the need for companies to become increasingly competitive and efficient, an insatiable search for continuous improvement has arisen. This allows those who apply this kind of ideology to observe: a reduction of production time, better ways of performing their procedures and operations, cost reductions as well as a cut on supply materials, and overall better working conditions for their employees and associates, all the while refining or, at least, maintaining the quality of their products. The main objective of this dissertation is to analyze the impact of the use of Lean tools in the composites industry, more specifically in the production of wind blade, recently implemented in the factory. The initial diagnosis and analysis consisted of finding possible flaws and ways of improvement. This was followed by sizing the expected gains, coming up with resolution tests, evaluating the necessary measures, deciding whether or not to implement them and, last but not least, updating any and all documentation related to the project. During the search for the improvement of this project, research was carried out regarding the use of Lean methodology, and tools such as Standard Work, 5S, BoM, Visual Management, and KPI, to help achieve the intended objective. The use of Lean tools has allowed for the quantities of materials used during the manufacturing process to decrease and, in some cases, eliminated. It also ensured sturdiness and strength whilst performing tasks as well as reducing operation time: less 70% during the calibration task, less 75% during bolts assembly, less 85% whilst creating and updating the Standard Works, and whilst tagging the placement of aerodynamic components on the blade, it was observed a decrease of 99%.
