The course is aimed at deepening the knowledge related to the metal forming processes and technologies. After an introduction of the fundamental principles related to the different techniques, processes and the equipment used in metal forming will be examined. In particular, the manufacturing of finished parts, made of metal alloys and composites is studied and analyzed especially in terms of the applications of technology in different industrial sectors

A fundamental aspect of the course deals with the evaluation of characteristics and properties of the finished product, also as function of the adopted technology. A particular analysis will be devoted to the evaluation of the technical/economic aspects, also in terms of the results deriving from quality control. The close contact with the more relevant industries, by means of targeted visits, provides a practical content for the course, and promotes a continuous updating on evolution and technological innovation.

FOUNDRY Principles of solidification of the alloys. Flow diagram and processing cycle typical of a foundry. Models, shapes and dies, traditional and special forming methods. Gravity casting, centrifugal casting and die casting. Investment Casting. Squeezecasting, Rheocasting, Thixomolding. Finishing operations and quality control; typical alloys and their fields of application, quality assurance. PLASTIC DEFORMATION Mold Casting and continuous casting. Recall of the theory of plasticity and of the theoretical fundamentals of the plastic deformation. Hot, semi-hot and cold deformation. Primary and secondary rolling. Forging, pressing, direct and inverse extrusion, drawing, blanking and forming of thin sheets. Residual stresses and analysis of the most common defects. Alloys for plastic deformation, properties and characteristics of the pieces obtained, quality control. POWDER METALLURGY Production Techniques and characterization of the product Pressing in molds: obtainable shapes and limits. Special compaction processes, cold and hot isostatic pressing. Sintering in furnaces: thermodynamic aspects of the process, furnaces and sintering atmospheres. Metal Injection Molding: characteristics and applications, raw materials and production cycle. FAST Techniques: SPS, EDS, CDS Free-form processes and 3D printing. Additive Manufacturing: main techniques and typical products DESIGN CRITERIA AND COST ANALYSIS Technical/economic comparison among the different alternative technologies and selection criteria for process optimization.

ModalitÓ di esame: prova orale obbligatoria; progetto di gruppo;
The verification of learning takes place through the final examination, which certifies the acquisition of knowledge and skill expectations. In particular, the examination consists of an oral test in which the technologies deemed most appropriate for the industrial production of specific components are considered and discussed, together with the analysis of the specific characteristics of the different manufacturing processes. The final mark will take into account the level of knowledge of the topics of the exam, as well as the critical analysis and communication skills of the student.
