Esta dissertação aborda a otimização de uma Máquina de Controle Numérico Computadorizado (CNC) para realizar solda 3D, uma técnica promissora na fabricação de estruturas metálicas complexas. O projeto, originado por uma atribuição específica, evoluiu de uma CNC inicialmente inoperante para uma máquina funcional e eficiente.
O estudo detalha a estrutura e componentes da CNC, destacando três graus de liberdade nos eixos X, Y e Z, essenciais para movimentos precisos. A máquina, inicialmente apresentando problemas elétricos e de movimentação, passou por uma revisão completa, incluindo a substituição da fonte de alimentação, a reorganização das ligações e a lubrificação dos componentes mecânicos.
O foco na solda 3D guiou a otimização, resultando em experimentos detalhados para aperfeiçoar parâmetros como aceleração e velocidade. Além disso, a adaptação do sistema elétrico para integrar a tocha de soldagem e a resolução de falhas durante a comunicação com o software Gcode Sender foram etapas fundamentais.
O êxito do projeto não apenas transforma a CNC em uma ferramenta de solda 3D funcional, mas também estabelece uma base para estudos futuros. O manual do utilizador em anexo oferece um guia passo a passo para operar a máquina otimizada. Este trabalho destaca a importância da otimização na automação industrial, demonstrando como desafios técnicos podem ser superados para impulsionar a eficácia operacional e explorar novas fronteiras tecnológicas.
This dissertation addresses the optimization of a Computer Numerical Control (CNC) Machine for 3D welding, a promising technique in the manufacturing of complex metal structures. The project, initiated by a specific assignment, has evolved from an initiall y non operational CNC to a functional and efficient machine. The study details the structure and components of the CNC, highlighting its three degrees of freedom in the X, Y, and Z axes, essential for precise movements. The machine, initially plagued by electrical and movement issues, underwent a comprehensive revie w, including the replacement of the power supply, reorganization of connections, and lubrication of mechanical components. The focus on 3D welding guided the optimization process, resulting in detailed experiments to refine parameters such as acceleration and speed. Additionally, adapting the electrical system to integrate the welding torch and resolving communication issues w ith the Gcode Sender software were crucial steps. The success of the project not only transforms the CNC into a functional 3D welding tool but also establishes a foundation for future studies.
