Obiettivi dell'insegnamento

The objective of the ADVANCED MANUFACTURING PROCESSES (AMP) class is to lead the students to master the most relevant advanced processing technologies, with special reference to processes with growing industrial importance and applied in different sectors, including automotive, aerospace, biomedical and energy. Additive, joining, shaping and subtractive manufacturing processes will be addressed, with a focus on the most innovative issues and at the key enabling technologies. New “Industry 4.0” digitalization tools will be explained through relevant examples.

The course starts from the classification of advanced machining processes, based on the elementary mechanisms and for each process presents the basic principles, the most relevant industrial solutions, the machines and the main applications. Numerical and PC-based exercises, semester projects, visits to laboratories, companies and trade fairs integrate the program.

Risultati di apprendimento attesi

After successfully taking credits for the AMP class, the students will achieve the following results.

For each manufacturing process, they will know the basics, the main capabilities, processable materials, the achievable geometries and tolerances, the productivity performances, the typical systems and machines.

They will master physical, numerical (simulation) and empirical models that will allow them to understand the sensitivity of the processes to the main process variables. Through numerical exercises, the students will learn how to quantitatively implement the models.

They will be able to select the appropriate technological processes for a given product, considering technical, economic and environmental issues.

Through reading and writing the semester project, they will familiarize with the scientific research, they will have a clear understanding of the state of the art and they will learn how to communicate the results of research activities.

Modalità di valutazione

The final exam will consist in a written test, where the student will have to solve some numerical problems and to answer some theoretical questions

This test allows to verify knowledge and understanding, application of knowlege and understanding, learning skills.

Before the first call of the winter exam session, the students, organised in groups of 4 or 5, must prepare a semester project, assigned by the teacher at the beginning of the course. The semester project is part of the evaluation, which can yield up to 2/30 additional points.

After the written test, an oral discussion will follow, allowing to assign the final grades, also checking communication abilities.
