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 equipments used in metal forming will be examined in details. The manufacturing of finished parts, made of metal alloys and metal based composites, is studied and analyzed, particularly 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.

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 industrial scenarios, combined to the evaluation of case studies, provides a practical content for the course, and promotes a continuous updating on evolution and technological innovation.

Modalità di esame: Prova orale obbligatoria; Elaborato progettuale in gruppo;
Exam: Compulsory oral exam; Group project;
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 analysis of the specific characteristics of the different manufacturing processes are considered and discussed. Students, divided in groups made of 2, will also be required to produce and illustrate into details a report on the proper manufacturing technique/s (at an industrial scale) of a given component, assigned during the course. Templates for the correct preparation and writing of the report will be shown during the course and made available on the portal. 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.
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam; Group project;
Expected learning results: Comprehension of the topics illustrated and ability to couple the parts' shape, size and material characteristics to the most proper metal forming process Ability to summarize the most relevant characteristics of each production process and analyze its pros and cons, also in terms of the process economics Criteria, rules and procedures for the exam: The verification of learning takes place through the final examination, which certifies the acquisition of knowledge and skill expectations.

Templates for the correct preparation and writing of the report will be shown during the course and made available on the portal. In the evaluation of the report, particular importance will be given to the approach chosen by the students. The indication of the proposed processing conditions is fundamental for a positive evaluation of the report. The mere description of theoretical aspects related to the production (i.e: without any parameter for the industrial production of the assigned component) will not guarantee a positive evaluation of the elaborate. The final mark will take into account the mark obtained with the report, the level of knowledge of the topics of the exam expressed in the oral exam, as well as the critical analysis and communication skills of the student.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
