- Contents
- Teaching provides the basic skills necessary to design the manufacturing cycle of a mechanical component. The main content covers metal manufacturing processes, typically applied to ferrous-based alloys and aluminium. Classical manufacturing processes such as casting, plastic deformation and machining processes are covered. Welding processes and innovative manufacturing processes such as additive manufacturing, are also covered.

- Educational objectives
- The teaching concurs to train the student in the technical-operational aspects of manufacturing technologies, provides basic techniques and tools for the design of fabrication cycles, including multi-process cycles for the fabrication of mechanical components and assemblies. The main objective of the teaching is to provide students with the basis for manufacturing process evaluation and planning, capable of translating the design contained in a drawing (CAD) into a physical object that meets design specifications. The main learning outcomes will be: 1) Knowledge of the basic principles of applied manufacturing technologies in the field of mechanical engineering. 2) Knowledge of the main manufacturing technologies based on the principles of solidification, plastic deformation, chip removal and additive manufacturing. 3) Ability to interpret indications of dimensional, geometric, and surface finish tolerances and identify correct technological operations. 4) Ability to plan a sequence of operations and steps suitable for making a mechanical component from a semi-finished or solid part. 5) Ability to dimension the process parameters and geometric quantities of the tools required for the manufacturing cycle. 6) Evaluate the effects of parameters on the manufacturing process.
- Prerequisites
- In order to understand and be able to apply most of the techniques described in the teaching, prior knowledge of Technical Drawing and General Physics is necessary.
- Teaching methods
- The course is organized into: - classroom lectures during which the topics covered in the course are addressed; - laboratory and computational exercises consisting of planning manufacturing cycles per part for which technical drawings are provided. The entirety of the teaching materials used during the course - e.g., lecture slides, performed and proposed exercises, tables, videos and other content - is available through the Unistudium platform.
- Other information
- More information is available through the dedicated Unistudium page. The lecturer is available for consultations at the end of each class; consultations with the lecturer in person or through the Microsoft Teams platform can also be arranged at other times.
- Learning verification modality
- The exam consists of two parts: - A written multiple-choice test including both computational exercises and theoretical questions on the entire landscape of course topics. - An oral test. The tests are aimed at ascertaining knowledge of the topics covered. The oral test is particularly aimed at ascertaining the student's ability to correctly plan manufacturing cycles, highlighting critical issues and approaches for their resolution or mitigation. Unless otherwise advised, the two tests are held on the same day, one following the other. The final grade is the arithmetic average of the grades obtained in the two tests. To pass the exam, however, it is necessary to obtain a score of at least 15/30 in the written test.
