Learning objectives
Knowledge and understanding: capacity to precisely interpret technical drawings, including symbols relating to mechanical machining operations. Knowledge of the main types of connections and transmissions.
Expertise: Ability to draft, freehand or with the use of set squares, technical drawings of mechanical components based on elevations or isometric drawings. Ability to assign tolerances and surface finish requirements based on the necessary component functionality.
Independent interpretation: Development of an adequate autonomy in the analysis of mechanical systems so as to correctly represent their individual components.
Communication skills: Further to production of correct and complete graphical representations necessary for conveying the form of simple mechanical components, students will acquire specific vocabulary inherent to mechanical drawing through frontal lessons and provided teaching material.
Interpretation capacity: Ability to interpret technical drawings and extract three-dimensional forms from them. Capacity to apply related knowledge where necessary (e.g. relationship between component functionality, design and production method).
Prerequisites
Important prerequisite is knowledge of the fundamentals of physics.
Course unit content
The course consists of 2 modules, Design and Technology, 6 CFUs each module
The Design module provides students with the fundamentals of industrial technical drawing. Initially the course covers the bases of mechanical drawing, orthogonal projections of simple and complex bodies, sections and axonometric projections. Subsequently, more specific topics will be covered including interpretation and arrangement of geometric dimensioning, surface finish and dimensional and geometric tolerances required for component functionality. Finally, the main types of permanent and releasable connections will be covered with particular attention to threaded connections, welded joints and mechanical transmissions. Practical exercises will be given during lessons throughout the entire course, covering all of the treated topics.

Bibliography
Slides used throughout the course will be available to students in PDF format via the Elly online platform, together with all teaching material and practical exercises covered during lessons. To download this material, students must log on to Elly and register for
- DISEGNO E TECNOLOGIE DI PRODUZIONE – Module 2
Further to material provided within the course, students can expand upon covered topics by studying from the following texts (in Italian):
1. M. Carfagni, R. Furferi, L. Governi, Y. Volpe - Esercizi di disegno meccanico. Zanichelli
2. Manfè, Pozza, Scarato. Disegno meccanico. (3 volumi), Principato.
3. Caligaris, Fava, Tomasello, "Dal progetto al prodotto", (3 volumi), Paravia
Teaching methods
The course is assigned 6 CFU for a total of 48 hours, with 2 hours/week assigned to lessons and 2 hours/week to tutorials. Themes covered in the course will be presented during lessons, both from a theoretical point of view and through practical examples. Refinement of the presented topics will be provided during subsequent tutorials, where students will resolve practical exercises.
Assessment methods and criteria
Common rules for both modules of the course:
- The exam in its entirety consists of a written assessment comprising both modules of the Design and Manufacturing Technology course and an optional oral exam comprising one or both modules.
- The two modules of the Design and Manufacturing Technology course are not separable.
- The written and oral exams are not separable and therefore must be undertaken in the same round.
- To pass the written exam, a minimum grade of 16/30 is required in both modules.
- There will be no mid-term assessments.
- All students that do not achieve a pass grade can view their marked exam through appointment with the course coordinator.
Specific rules for the Design Module:
The written exam is 2 hours in length and comprises two tasks:
- Task 1: preparation of a technical drawing of two components based on a small assembly drawing. Further to simple graphical representation with orthogonal projections, it is necessary to indicate dimensions, surface finish and tolerances necessary for complete component functionality.
- Task 2: response to a question relating to part of the theory covered during the course.
Written exams are assigned grades from 0 to 30, with the two tasks weighted 24/30 and 6/30, respectively (tasks 1 and 2).
The oral exam, which will begin with a discussion of the written exam, aims to verify the candidate’s ability to discuss and reason in relation to any of the themes addressed during the course. The maximum variation in grade with respect to the written exam is +/- 3 points.
