Abstract(s)
As tecnologias de fabrico avançada têm desempenhado um papel crucial na melhoria
da qualidade e precisão de dispositivos médicos na área da ortoprotesia. A utilização
de máquinas Computer Numeric Control (CNC) tem permitido a produção de moldes
positivos mais precisos e com melhores acabamentos, reduzindo a necessidade
de intervenção humana intensiva e aumentando a eficiência dos processos de fabrico
de próteses e ortóteses.
Esta dissertação tem como objetivo a requalificação de uma máquina CNC de
três eixos, existente na empresa Padrão Ortopédico, com o intuito de aprimorar a
precisão e a eficiência no fabrico dos moldes utilizados no fabrico de dispositivos
médicos. A requalificação visa otimizar a integração dos componentes do sistema
CNC, sendo o controlo efetuado através de um Arduino Mega 2560, equipado com
o firmware Grbl-Mega-5X.
O trabalho realizado incluiu a análise e reconfiguração das ligações elétricas, a
otimização dos drivers e ajustes no software nos parâmetros de controlo dos motores,
para atingir a precisão necessária. Além disso, foi desenvolvida uma interface
gráfica de controlo, através do software Grbl Controller, que facilitou a operação da
máquina e a sua monitorização em tempo real, permitindo que o processo de fabrico
fosse realizado de forma mais eficiente e com menor margem de erro, beneficiando
diretamente a qualidade e a personalização dos dispositivos ortopédicos produzidos.
Advanced manufacturing technologies have played a crucial role improving the quality and precision of medical devices in the field of orthotics and prosthetics. The use of Computer Numeric Control (CNC) machines has enabled the production of more precise positive molds with better finishes, reducing the need for intensive human intervention and increasing the efficiency of the manufacturing processes for prostheses and orthoses. This dissertation aims to requalify a three-axis CNC machine, currently in use at Padrão Ortopédico, with the goal of enhancing the precision and efficiency in the manufacturing of molds used for medical devices. The requalification seeks to optimize the integration of the CNC system components, with control being managed by an Arduino Mega 2560 equipped with the Grbl-Mega-5X firmware. The work carried out included the analysis and reconfiguration of the electrical connections, optimization of the drivers and adjustments on the motor control parameters, to achieve the required precision. Additionally, a graphical user interface was developed using Grbl Controller software, helping on the operation of the machine and real-time monitoring. This allows the manufacturing process to be carried out more efficiently and with a lower margin of error, directly benefiting the quality and customization of the orthopedic devices produced.
