Teaching description

Teaching program is provisional and may be subject to changes

You must have passed the Examination of Mechanical Technology. The contents of the Industrial Design Drawing and knowledge of Technical Industrial Design are also useful.

The course aims to deepen the aspects related to manufacturing technologies applied in aeronautical constructions, with particular reference to the materials selection and application and the related transformation technologies. Materials/technologies solutions will mainly be used for the construction of airframe and motor structures. The aspects of the "Machinability of materials for aeronautical application" in terms of cutting processes will be discussed. The study and the classification of light alloys for aeronautical application, as well as superframes for airframe and motor application, will be addressed. In particular, the main aspects related to the metallurgy and workability of Alluminum alloys and Nickel and Titanium superalloys will be studied taking into account the comparison with real applications. In the field of plastic deformation technologies, the basic principles of Super Plastic Forming and its applicability to the aeronautics industry will be illustrated. At the same time, aspects regarding assembly operations will be dealt with, in particular those relating to welding of metal materials and the riveting of components. We will then proceed to a technology analysis of the application of composite materials to the aeronautical sector. On some aspects discussed in the theory section, numerical exercises will be carried out to familiarize with the physical quantities that characterize them and laboratory exercises will be focused on Finite Element simulation tools for the machining and forging processes. Moreover, the course aims to provide an overview of Additive Manufacturing processes, explain their underlying physical principles, discuss current research and an appreciation for why AM is so important to many branches of industry. In order to take maximum advantage from the capabilities of additive metal technology in the most economical way, will be studied how to design for this technology by following its principles. At the same time, the aspects relating to the design for additive metal manufacturing (DFAM) concept and, the act of integrating product design and additive manufacturing principles into one activity, will be illustrated. Laboratory exercises will be carried out by 3D printer with FFF (Fused Filament Fabrication) and Wax Jet Printing technology, in addition to laboratory exercises that will be focused on tools for the finite element simulation of additive processes.

During and a the end of the course, the student should be able to acquire:
- An in-depth knowledge of materials for aeronautical application and processes for their transformation;
- A basic knowledge of the Alluminum alloys, Nickel and Titanium superalloys characterization;
- A basic knowledge of the Additive Manufacturing Technologies in terms of characterization and use;
- A basic knowledge of composite materials use for aeronautical applications;
- A basic knowledge of the Finite Element manufacturing processes simulation with specific focus on machining and forging.
- Knowledge for characterization and use of Additive Manufacturing technologies.
- Basic knowledge of Design for Additive Manufacturing.

Attività frontale di 81 ore.

Written, oral, written and/or oral.
The exam consists of two consecutive parts:
- A first written part (its duration is about 1 hour) in which the student have to solve a task related to the topics discussed in the course; the test aims to determine the student's ability to carry out calculations related to the physical quantities that characterize the processes discussed during the course;
- The second oral part (which begins immediately after the written part) in which the student discusses both the written part and other contents of the course, in order to illustrate their understanding and knowledge level of the topics discussed and the ability to deliver it to perform relevant kinematic and dynamic analyzes.
