LEARNING OUTCOMES

The course aims at:

- providing the basic instruments for representing the shape of a mechanical piece (with hand made sketches, too)

- offering the fundamentals for the definition of the functional features of a part

- illustrating the different joining elements with related criteria

- giving students the essential learning about a 2D CAD system (to be used for drawings) 

AIMS AND LEARNING OUTCOMES

In order to facilitate the learning of the methods of representation of 2D tables to the students, grouped in pairs, themes are assigned that they develop independently. The idea is to take advantage of learn by doing and learn by trial and error. The teacher guides and assists the students without interfering with their reasoning and then asks the students to show the result to the whole class. The teacher then highlights and explains the errors and corrects them in real time.

TEACHING METHODS

Lessons and exercises in computer room.

SYLLABUS/CONTENT

Standardisation: international and national standards. Standard for technical drawing. Drawing types. Shape and size representation of a mechanical part: the graphic model. Hand-made sketches. Orthogonal projections, sections, dimensioning (complying the ISO standards). Overview on axonometric and slanted views. Summary on basic mechanical components.

Manufacturing tolerancing: dimensional, geometrical, surface tolerancing.

Non-permanent joining parts (threaded items, centering elements) and stable joining parts.

Guidelines on the elements shape depending on the manufacturing process and the material used.
