Abstract(s)
Nos dias de hoje, a sobrevivência de uma empresa no mercado está fortemente ligada ao
fator de competitividade da mesma. O setor automóvel chega a atingir níveis de competitividade
elevadíssimos, sendo por vezes estimulados por quebras ou derrapagens na procura, provocadas
por fatores externos à indústria, como por exemplo a quebra relativa ao vírus covid-19, que
levou as empresas a adotarem estratégias de contenção de custos e aumento de produtividade,
com intuito de se manterem vivas no mercado.
No presente trabalho é exposta uma ferramenta muito versátil e eficaz na resolução de
problemas, com foco na obtenção de resultados monetários positivos. A metodologia em
observação é o six sigma, a sua aplicação tem como propósito a redução de custos em
ferramentas de corte, na empresa Huf Portuguesa.
Atualmente, para além da empresa em análise estar a atravessar uma restruturação interna,
esta sofre também as consequências da pandemia covid-19, pelo que, é necessário criar e adotar
estratégias para o aumento dos resultados operacionais da empresa. Daí que, é necessário
empregar o six sigma na análise dos processos de fresagem das diversas linhas de montagem
da empresa. O projeto de melhoria terá como enfoque o aumento da rentabilização da utilização
das fresas atendendo ao tempo de vida útil das mesmas.
O six sigma, é uma metodologia que quando aplicada corretamente, pode potenciar os
resultados da empresa, isto porque, a estrutura rígida e dinâmica da ferramenta DMAIC
possibilita criar e implementar melhorias estáveis nos processos.
O trabalho desenvolvido encontra-se dividido em duas partes, uma primeira parte com a
revisão literária, no qual inclui uma introdução ao tema, uma revisão ao six sigma e uma
pequena abordagem aos processos de corte, e uma segunda parte relativa ao caso de estudo.
No desenvolver do caso de estudo, constatou-se que os resultados operacionais de uma
empresa podem ser potenciados com a utilização da ferramenta de melhoria six sigma, além do
que, também se verificou que o operário fabril tem uma forte influência no output do processo
de fresagem. Todavia, o que se constatou foi uma dificuldade na utilização correta dos métodos
de análise indiretos. Contudo, também foi possível identificar a importância da uniformização
de critérios de análise, a utilização correta dos dados e a impossibilidade de analisar certas
variáveis de entrada do processo de fresagem.
ABSTRACT: Nowadays, the survival of a company in the market is strongly linked to its competitiveness factor. In the automotive insdustry, it reaches extremely high levels of competitiveness, sometimes being stimulated by declines or shifting in demands, caused by external factors to the industry, such as the crash related to the covid-19 virus, which led companies to adopt strategies of cost containment and increased productivity, in order to stay alive in the market. In this work, a very versatile and effective problem solving tool is exposed, with a focus on achieving positive monetary results. The methodology under observation is the six sigma, its application aims to reduce costs in cutting tools, in the company Huf Portuguesa. Currently, beyond the company in analysis is undergoing to na internal restructuring, it is also suffering the consequences related to the pandemic of covid-19, so it is necessary to create and adopt strategies to increase the company's operating results. Hence, it is necessary to use six sigma in the analysis of the company milling processes from diferent assembly lines. The improvement project is focus on increasing the use of the cutting tools attending on each cutting tools life time. Six sigma is a methodology that, when applied correctly, can enhance the company's results, because the rigid and dynamic structure of the DMAIC tool makes it possible to create and implement stable improvements in the processes. The work developed is divided into two parts, a first part with the literary review, which includes an introduction to the subject, a review about the six sigma and a small approach to the cutting processes, and a second part related to the case of study. In developing the case of study, it was found that the operational results of a company can be enhanced with the use of the six sigma improvement tool, in addition to that, it was also found that the factory worker has a strong influence on the output of the milling process. However, was found a difficulty in the correct use of indirect analysis methods. However, it was also possible to identify the importance of standardizing analysis criteria, the correct use of data and the impossibility of analyzing certain input variables in the milling process.
