Programme

AIM OF THE COURSE. The course in Manufacturing Technology provides the student with the basic knowledge of the main mechanical processing technologies. Specifically, the course aims to illustrate, transversely, the traditional processes of transformation and mechanical processing, starting from the study of the properties of the materials and related techniques of characterization and arriving at a detailed analysis of the technologies and related processing parameters, as well as the productive context in which they fit. The course aims to provide the student with all the tools to define the processing cycle of a component and to highlight the links between the parameters of the process, the properties of the raw material and the final properties of the semi-finished / finished product. The contents of the course will pour, in a first introductory part, on the study and understanding of the micro / macroscopic properties of the materials and related analysis techniques. Subsequently, the main processing technologies will be examined, such as the manufacturing processes for casting, the processing by plastic deformation, the machining operations for chip removal and the connection processes. Every single processing technology will be analyzed in terms of operating principle, type of production context and technological criticality.
