Abstract(s)
Quando um processo depende de máquinas para obtenção de um determinado tipo
de produto, a eficiência de uma secção ou empresa pode ser avaliado recorrendo ao
cálculo do indicador da Eficiência Global dos Equipamentos (Overall Equipment
Effectiveness ou OEE). A aplicação da Manutenção Produtiva total (Total Productive
Maintenance ou TPM) incide e melhora nas três grandezas (desempenho,
disponibilidade e qualidade) relativas ao cálculo do OEE, que permitem ser usadas
como referência para possíveis melhorias futuras.
Este estágio surgiu no âmbito do Mestrado em Engenharia Mecânica e Gestão
Industrial. O estágio foi desenvolvido em ambiente industrial na empresa Ara Shoes
Portuguesa, mais concretamente na secção de injeção ao corte.
O principal objetivo do trabalho foi implementar o estudo do O.E.E e com o auxílio das
ferramentas Lean, como o diagrama de Isikhawa e ciclo PDCA, iniciar um processo de
melhoria continua naquela seção e, consequentemente, aumentar a produtividade.
O principal foco foi a observação de processos, organização do espaço de trabalho,
introdução de documentação para análise do O.E.E. e formação dos colaboradores. O
cálculo do OEE permitiu perceber qual a influência de cada um dos seus indicadores no
desempenho do processo produtivo.
Após a conclusão do trabalho é possível afirmar que os objetivos e trabalhos propostos
à empresa foram concretizados com sucesso, existindo, no entanto, ainda muita
margem para progressão.
When a process relies on machinery to obtain a specific type of product, the efficiency of a section or company can be evaluated by calculating the Overall Equipment Effectiveness (OEE). The implementation of Total Productive Maintenance (TPM) focuses on improving the three main components of OEE—performance, availability, and quality—which serve as benchmarks for potential future improvements. This internship was carried out as part of the Master’s program in Mechanical Engineering and Industrial Management. The project took place in an industrial environment at Ara Shoes Portuguesa, specifically in the injection-to-cutting section. The main objective of the work was to implement an OEE study and, with the support of Lean tools such as the Ishikawa diagram and the PDCA cycle, initiate a process of continuous improvement in this section and consequently increase productivity. The primary focus was on observing processes, organizing the workspace, introducing documentation for OEE analysis, and training employees. The calculation of OEE allowed for the identification of the influence of each of its indicators on the performance of the production process. Upon completion of the project, it is possible to state that the objectives and tasks proposed to the company were successfully achieved. However, there remains significant room for further progress.
