Abstract
Smart manufacturing, a key aspect of Industry 4.0, focuses on Additive Manufacturing (AM) as a revolutionary approach. Unlike traditional manufacturing methods, AM involves layer-by-layer material addition to create parts. AM offers advantages such as improved finish, reduced manufacturing steps, and minimized material waste. Wire Arc Additive Manufacturing (WAAM) is a notable AM process for manufacturing metallic parts using cost-effective equipment, which saves materials and reduces environmental impacts. However, the accumulation of excessive heat in previously deposited layers during interpass deposition leads to macro and microstructural defects. To ensure high-quality and structurally sound products, controlling interpass temperature in the WAAM process is crucial. This work aims to develop a forced air-cooling system for WAAM, employing a microcontroller for integral control, a temperature sensor for interpass temperature measurement, a compressor for supplying gaseous fluid, and an actuator to control airflow. The system operates after each layer deposition to decrease the interpass temperature until reaching the desired level. The results demonstrate the system's functionality, enhancing manufacturing speed while reducing the time required to achieve the desired interpass temperature. This research contributes to understanding the influence of interpass temperature on WAAM-produced parts and paves the way for further studies in this area.
