| TECHNOLOGIES AND MANUFACTORING SYSTEMS
(objectives)
The Course of Technologies and Processing Systems provides students with the basic knowledge to orientate themselves among the traditional manufacturing processes of non-metallic materials. Specifically, the course allows the development of knowledge on the technologies of polymeric materials, composites and ceramics, materials that occupy an increasingly important weight in modern manufacturing processes. It is therefore a Course complementary to Mechanical Technology that studies the transformation processes of metal materials only. The Course of Technologies and Processing Systems includes elements on processes inherent in powder metallurgy and the related transformation processes. It also provides the knowledge base for the main unconventional and advanced processing technologies, including rapid prototyping technologies. Finally, it provides the rudiments on the so-called "green" technologies and the first indications on the aspects inherent to safety in production processes.
