Abstract(s)
Este estudo foi desenvolvido no âmbito da Unidade curricular de Dissertação / Projeto /
Estágio do Mestrado em Engenharia Mecânica – Ramo de Gestão Industrial do Instituto
Superior de Engenharia do Porto, com aplicação em ambiente industrial numa empresa
metalomecânica da indústria automóvel.
O projeto desenvolveu-se na secção de inspeção e embalagem de produto acabado da
empresa IETA S.A., fornecedora de estruturas metálicas, com o objetivo de minimizar as
reclamações recebidas por defeitos originados no processo de fabrico. A abordagem a este
estudo iniciou-se pelo registo e análise de dados e consequente formulação e
implementação de melhorias ao processo de fabrico, com recurso a metodologias e
ferramentas Lean.
A existência de um problema relacionado com o processo de fabrico em vigor permitiu o
conhecimento dos hábitos de trabalho e a apresentação de propostas de melhoria ao layout
fabril e ao método de trabalho em vigor na secção. A análise dos problemas existentes
possibilitou a identificação de oportunidades de melhoria em outras áreas do processo,
revelando-se o poder das ferramentas utilizadas na análise de dados.
Este estudo de investigação revelou ser muito enriquecedor e motivador tendo
proporcionado a aplicação de conteúdos científicos Lean em ambiente industrial ficando
provada a mais-valia da sua implementação.
A aplicação das ferramentas e metodologias Lean estudadas permitiram efetuar uma
análise cuidada dos dados conduzindo a propostas de melhoria vantajosas e compatíveis
com as necessidades da empresa. As propostas apresentadas, apesar de não terem sido
todas implementadas, resultaram num impacto positivo no processo de fabrico com uma
eliminação expectável de 38% dos defeitos reclamados.
This study was developed within the course of Thesis / Project / Internship of the Master Degree in Mechanical Engineering – Industrial Management branch from the Polytechnic of Porto, School of Engineering, with application in industrial environment in a metalwork company of the automotive industry. The project was developed in the final product inspection and packaging area of the company IETA S.A., tier 1 supplier of metal structures, with the goal of minimize claims of defected parts with defects caused by the manufacturing process. The approach of the study began with the record and analysis of data and consequent improvement formulation and implementation to the manufacturing process using Lean Manufacturing technics. The existence of a knowing problem related with the manufacturing process allowed the knowledge of working habits and the presentation of improvement proposals to the plant layout and to the work method. The analysis of the existing problems enabled the identification of improvement opportunities in other areas of the process, revealing the power of the tools used to analyse data. This investigation study reveals very enriching and motivator having proportionated the application of scientific Lean principles in an industrial environment getting tested the added value of its implementation. The application of the studied Lean tools and methodologies allowed a meticulous analysis of data conducting to advantageous improvement proposals compatible with the company needs. Although they have not all been implemented, the presented proposals resulted in a positive impact in the production process with estimated elimination of 38% of claimed defects.
