Abstract

Training in CNC machine operation and CAM software, all already existing at LAPRAS. Train the scholarship holder to become familiar with the CAM machines and programs to be used in the project. Part design to study the polishing process. The hybrid process includes AM made by the ROMI machine, with subsequent HSM - High Speed Machining - machining. To improve the surface finish of the piece, it will be polished on the machine itself. Monitoring the manufacturing of DED parts. The designed part will be manufactured in the desired shape for machining experiments. Manufacturing will take place using the hybrid machine with the Hybrid Mfg system directly coupled to the machining center. Preparation of set-ups. The scholarship holder will prepare, with the help of the Mechanical Technician, the machine, fixing devices, tools, CN programs and everything else necessary to carry out the polishing tests. Polishing experiments. The student will follow the preparation carried out by the LAPRAS Mechanical Technician and the carrying out of polishing experiments. Analysis of results and monitoring of other trials. Given the experimental results found and the existing theories and proposed models, the scholarship holder and the researchers will analyze the data. Reports. The scholarship holder, under the guidance of the researcher, will prepare reports in a scientific manner and with all the rigors of academic language. Bibliographical Research: The scholarship holder will be constantly updating themselves through existing publications in the area.
