Abstract(s)
Na indústria metalúrgica de precisão, o rigor e a eficiência são cruciais. Para que tais ideais sejam alcançados, os diferentes processos de maquinagem têm de ser pormenorizadamente analisados e exigem um controlo contínuo, desde o início do processo até à sua conclusão. Este trabalho irá focar-se na análise dos processos de maquinagem, no controlo de qualidade e estudo de não conformidades, com o intuito de analisar o impacto na sustentabilidade da empresa. Para análise dos processos de maquinagem, ter-se-á em consideração o toleranciamento e grau de acabamento em peças maquinadas, os sistemas de fixação de peças e ferramentas, bem como o desgaste das ferramentas. Relativamente ao controlo de qualidade, será efetuada uma análise aos sistemas convencionais e avançados de controlo. Serão abordadas as vantagens dos sistemas avançados de controlo e de que forma podem influenciar a qualidade do produto final. Irá analisar-se as ferramentas da qualidade e a importância de elementos estatísticos para a análise de não conformidades. Depois de analisada a qualidade, é consequentemente fulcral avaliar os métodos práticos usados para garantir essa qualidade. Em termos práticos, será abordada uma vertente empírica vivenciada na empresa de acolhimento. Depois da caraterização do fluxo produtivo, será efetuada a identificação e segmentação de problemas, sendo estes problemas de não qualidade ou de carência na classificação de fornecedores. Com vista à consolidação das vertentes bibliográfica e prática, serão posteriormente indicadas as diferentes formas de resolução de problemas de não qualidade, o modelo de classificação de fornecedores, e também os fatores que podem ser influenciados pela não qualidade. Pretende-se, deste modo, transmitir uma ideia do impacto da qualidade na sustentabilidade de uma indústria metalomecânica.
Accuracy and efficiency in the precision metallurgical industry are crucial. In order to achieve these ideals different machining processes have to be analyzed in detail and it is necessary a continuous control from the beginning of the process to its final. This academic work will focus on the analysis of machining processes, quality control and nonconformity studies, in order to analyze the impact on company's sustainability. For analysis of the machining processes, there will be taken into consideration the tolerance and level of finishing in machined parts, holding systems for parts and tools, as well as tool wear. Regarding quality control, an analysis will be made of conventional and advanced control systems. The advantages of advanced control systems will be addressed and also how they can influence the quality of the final product. It will be analyzed the quality tools and the importance of statistical elements for analysis of nonconformities. Once the quality is analyzed, it is therefore crucial to evaluate the practical methods used to guarantee this quality. In practice, an empirical case will be studied accordingly with the experience in the host company. After the explanation of the productive flow, the identification and segmentation of problems will be carried out, being these non-quality problems or lack of suppliers’ classification problems. In order to consolidate the theoretical and practical aspects, there will be explained the different ways of solving non-quality problems, a classification model of suppliers was created and also the factors that may be influenced by non-quality were identified and fixed. The aim is to convey the impact of quality on sustainability in a metalworking industry.
