Abstract(s)
Este projeto de dissertação apresenta como principal objetivo a uniformização do processo produtivo, mais concretamente do fabrico de caixas em estruturas para moldes. A organização dos recursos e a uniformização dos processos de fabrico, permite aos intervenientes ter apenas acesso às informações essenciais para a produção e a uniformização do processo de fabrico permite tornar o conhecimento acessível com utilização de uma linguagem standard, por outro lado permite uma rastreabilidade maior das operações com controlo mais rigoroso, permitindo processos de melhoria. Para o desenvolvimento deste projeto foi necessário realizar pesquisas mais exaustivas sobre a temática maquinagem, ferramentas utilizadas, tipos de fixação de ferramentas, tipos de fixação de peças, operações de maquinagem e de que forma os moldes para injeção de plástico são constituídos. Após esta primeira abordagem foi necessário entender o processo produtivo, de forma a assimilar as práticas da empresa e perceber de que forma poderia atuar para atingir os objetivos propostos. Numa primeira fase, foi realizado um inventário das ferramentas utilizadas e foram desenvolvidos documentos de apoio com as ferramentas e os parâmetros de corte definidos pelos fabricantes. Após esta primeira fase, foi realizado um levantamento dos processos de fabrico de caixas registados na base de dados da empresa, de forma a avaliar os procedimentos adotados e assim adaptar os novos procedimentos à dinâmica da empresa. O principal objetivo foi permitir a uniformização do processo de fabrico de forma a tornar a informação acessível a todos os colaboradores e, de uma forma indireta, permitir avaliar o processo e proceder a melhorias a curto e longo prazo. Para efetuar este trabalho recorreu-se a Software CAD e CAM, essenciais para o apoio à produção. No final do projeto, verificou-se melhorias na seleção dos parâmetros de corte das ferramentas e foi validado um dos procedimentos.
The main objective of this dissertation is to standardize the production process, specifically the manufacture of boxes in structures. The organization of resources and the standardization of the manufacturing processes allows the participants to have access only to the essential information for production and the standardization of the manufacturing process, using a standard language this way will make this easy access to everyone on the other hand allows a greater traceability with close control, enabling improvement processes. Was necessary to carry out an extensive research about CNC machining, tools used, types of tool clamping, types of part clamping, machining operations and how plastic injection molds are made, this was made to facilitate the development and improving the dissertation. In order to assimilate the company's practices and understand how it could act to achieve the proposed objectives was necessary understand the production process. Initially, an inventory of the tools used was made and supporting documents were developed with the tools and cutting parameters defined by the manufacturers. In the first stage, a survey of the box manufacturing processes registered in the company database was carried out in order to evaluate the adopted procedures and thus adapt the new procedures to the company dynamics. The main objective on this project is to enable the standardization of the manufacturing process to make information accessible to all employees and, indirectly, to evaluate the process and make short and long term improvements. To carry out this work, we used CAD and CAM Software, essential for production support. The organization made some improvements due to the project specific on the selection of the cutting tolls and only one procedure was validated.
