Resumo(s)
Nos últimos anos, tem-se vindo a testemunhar uma crescente competitividade ao nível
do setor automóvel. A possibilidade de escolha de inúmeras características num veículo, isto
é, o seu forte fator de customização, além de trazer vantagens competitivas para as empresas
do setor, tem vindo a conferir um nível de complexidade extremamente elevado a todo o pro-
cesso de conceção e fabrico de um automóvel. Adicionalmente, os avanços tecnológicos veri-
ficados nos últimos anos, possibilitaram a incorporação de variadas funcionalidades com ca-
riz tecnológico nos automóveis. Estes passaram a ser altamente dependentes de numerosos e
variados sistemas elétricos, contribuindo para o aumento da referida complexidade.
A elevada dependência dos sistemas elétricos tem repercussões ao nível da produção
de cablagem, que tem que apresentar padrões de qualidade elevados. Desta forma, o processo
de fabrico e testagem destes produtos tem vindo a tornar-se cada vez mais complexo e exi-
gente, por forma a ir ao encontro das necessidades da indústria automóvel. A elevada varia-
bilidade que a cablagem apresenta, reflete-se na necessidade da produção de equipamentos
de teste altamente variáveis e, por isso, com um elevado fator de customização. Este elevado
fator representa um desafio em termos de eficiência ao nível dos processos produtivos.
A adoção de tecnologias de Indústria 4.0 provou conferir flexibilidade aos processos
produtivos dos mais variados contextos industriais, aumentando a eficiência dos mesmos,
sem comprometer a qualidade, os custos de produção e os tempos de ciclo de fabrico dos
produtos. Assim, a aplicação deste tipo de tecnologias no contexto industrial da produção de
equipamentos de teste de cablagem poderá revelar-se benéfica.
O estudo de caso abordado ao longo da presente dissertação tem por base o contexto de
uma empresa de equipamentos de teste de cablagem. Analisou-se o processo produtivo da
fase de maquinação dos equipamentos de teste e, após a recolha de dados acerca das ativida-
des desempenhadas durante o processo de maquinação, procedeu-se ao levantamento de to-
das as ocorrências que contribuem para atrasos e quebras produtivas. Com base na informa-
ção recolhida, e com o intuito de agilizar e melhorar o processo produtivo da empresa, foi
proposta uma rede de soluções composta por tecnologias de Indústria 4.0 e baseada no con-
ceito de Internet of Things, que, no contexto das metodologias de fabrico da empresa, poderá
tornar o sistema produtivo mais eficiente e menos propício a falhas.
In the last few years, an ever-growing competition in the automotive industry has been witnessed. The high customization factor, which is present in the automotive industry, that is, the possibility of selecting countless different features in a vehicle, brings competitive ad- vantages to stakeholders. However, it also brings a high level of complexity to the production process of a vehicle. Additionally, the current technological developments have enabled the integration of countless technological functionalities into vehicles. These vehicles have be- come highly dependent on countless electrical systems, which also contributes to an increase in terms of complexity of the production process of the vehicles. The dependency on such electrical systems has repercussions in the production process of vehicle cable harnesses, which must comply with high-quality standards. Thus, its produc- tion process has become highly complex in order to meet the automotive industry's require- ments. The high variability of the cable harnesses causes a pressing need of producing highly customized test equipment, which represents serious challenges regarding the efficiency of its production process. The adoption of Industry 4.0 technologies confers flexibility to several different produc- tion processes, increasing their efficiency without compromising the quality of the products, their cost, variability, and cycle time. Thus, the implementation of such types of technologies in test equipment industrial units for cable harness factories might present itself beneficial. The case study presented throughout this thesis took place in a cable harnesses test equipment company. The machining phase of the test equipment was analysed and, after the collection of the data regarding the activities performed during this phase, the occurrences that caused production delay or breaks were collected. Furthermore, in order to improve the production process, a network of I4.0 solutions based on the concept of Internet of Things (IoT) is proposed by considering the company's manufacturing methodologies in order to make the machining phase more efficient and less prone to faults.
