O presente trabalho tem como objetivo um estudo para a implementação de metodologias Lean, tendo em vista a redução de movimentações num setor de maquinação computadorizada, procurando aumentar o nível de eficiência e produtividade. O desenvolvimento deste trabalho encontra-se dividido em três etapas, estudo de caso, Layout atual e novo Layout, nas quais foram aplicadas as ferramentas Lean Work Standardizantion, 5S, Kanban, Single Minute Exchange of Die,Visual Management, Standerdized Work Combination Table e Diagrama de Movimentações para o estudo de movimentações do Departamento de Maquinação CNC, otimizando os diferentes postos de trabalho e as tarefas a eles associadas. No estudo de caso com a implementação das ferramentas Lean registou-se uma redução de movimentações em 50%, um aumento na eficiência e produtividade em 8% e 17,78%, respetivamente. Na comparação entre o Layout atual e novo Layout, registou-se uma redução de movimentações de controlo dimensional em 60,61%, movimentações de logística de stocks em 81,74% e movimentações do departamento de desenvolvimento técnico em 91,30%. Com a implementação das diversas ferramentas Lean, concluímos que os objetivos definidos foram concretizados, reduzindo os desperdícios de movimentações nos diversos pontos críticos distribuídos pelo Departamento de Maquinação CNC, aumentando a eficiência, eficácia, produtividade e fluidez do fluxo produtivo.
The main purpose of this study is to implement Lean methodologies with the aim to reduce movements in a computerised machining sector, seeking to increase efficiency and productivity levels. The development of this work is divided into three stages, case study, current Layout and new Layout, in which the following Lean tools, Work Standardization, 5S, Kanban, Single Minute Exchange of Die, Visual Management, Standardized Work Combination Table and Spaghetti Diagram were applied to study the movements of the CNC Machining Department, optimising the different workstations and their associated tasks. In the case study involving the implementation of Lean tools, there was a 50% reduction in movements and an increase in efficiency and productivity of 8% and 17,78%, respectively. In the comparison between the current Layout and the new Layout, there was a 60,61% reduction in dimensional control movements, an 81,74% reduction in stock logistics movements and a 91,60% reduction in the technical development department movements. With the implementation of various Lean tools, we concluded that the defined objectives were achieved, reducing wasteful movements at various critical points throughout the CNC Machining Department, increasing efficiency, effectiveness, productivity, and fluidity of the production flow.
