Abstract(s)
Este projeto desenvolvido em ambiente industrial numa empresa de fabricação de contraplacados de madeira teve como objetivo a identificação de melhorias ao nível do processo de fabrico de uma gama especifica de produtos recorrendo à utilização de ferramentas da filosofia lean. O estudo incidiu principalmente em quatro equipamentos presentes no processo: duas prensas, uma Serra Manual e uma Lixadora/Calibradora. Pretendia-se com a elaboração do projeto de melhoria, atingir um aumento dos valores da produtividade em 3% para as prensas e Serra Manual e de 20% para a Lixadora/Calibradora. No desenrolar do projeto começou-se por fazer uma análise do estado atual do processo, recorrendo ao estudo dos tempos e à elaboração de um mapa de fluxo de valor (VSM) e posteriormente com base nesse estudo identificar potenciais desperdícios e oportunidades de melhoria. Após isto, iniciou-se o desenvolvimento de um relatório A3, sendo propostas contramedidas que visavam corrigir os desperdícios detetados. Depois de uma avaliação, foram selecionadas as medidas a serem implementadas. Construiu-se de seguida um plano de implementação com o fim de eliminar os desperdícios detetados, procurando atingir o valor objetivo selecionado para o aumento da produtividade. Depois de elaborado todo o plano de implementação e concretizadas boa parte das medidas, fez-se uma verificação dos resultados expectáveis, registando-se a previsão de aumentos de produtividade de 20,92% para a Prensa 2; de 1,77% para a Prensa 1; de 7,14% para a Serra Manual; e 25,5% para a Lixadora/Calibradora. Espera-se assim então atingir os objetivos de aumento de produtividade previstos, excetuando-se o caso da Prensa 1. Com este trabalho foi possível aplicar com sucesso um conjunto de ferramentas de melhoria da filosofia Lean obtendo-se resultados significativos. A implementação do presente projeto também permitiu à empresa o desejado aumento de produtividade bem como um reforçar da mensagem de melhoria entre os respetivos funcionários.
This project developed in an industrial environment in a wood plywood manufacturing company aimed to identify improvements in the manufacturing process of a specific range of products using lean philosophy tools. The study focused mainly on four equipments present in the process: two presses, a Manual Saw and a Sander / Calibrator. The aim of the improvement project was to achieve a productivity increase of 3% for the presses and manual saw and 20% for the Sander/Calibrator. In the course of the project, it started by analyzing the current state of the process, using the study of times and the elaboration of a value stream mapping (VSM) and later based on this study to identify potential waste and opportunities for improvement. Following this, the development of an A3 report began and countermeasures were proposed to correct the detected waste. After an evaluation, the measures to be implemented were selected. An implementation plan was then built to eliminate detected waste, seeking to achieve the target value selected for increased productivity. After the entire implementation plan was prepared and most of the measures were implemented, the expected results were verified, with a forecast of productivity increases of 20.92% for Press 2; 1.77% for Press 1; 7.14% for the Manual Saw; and 25.5% for the Sander/Calibrator. Thus, it is expected to achieve the expected productivity increase objectives, except for Press 1. With this work it was possible to successfully apply a Lean philosophy improvement toolkit, obtaining significant results. The implementation of this project also allowed the company to achieve the desired productivity increase as well as reinforce the message of improvement among its employees.
