Objectives

The aim will be to provide students with the knowledge and methods of graphic communication in preparation for subsequent training activities in the fields of industrial technical design, applied mechanics, mechanical design and processing.
i. knowledge and understanding.
The main expected learning outcomes are the following:
• Know the role of technical design in the production cycle;
• Understand the importance of unification norms and systems;
• Know the main devices for manual and automatic drawing;
• Know the main methods of graphic representation;
• Understand the relationships between the design of a mechanical component and the mechanical processes necessary for its realization;
ii. applying knowledge and understanding.
• Ability to drawing the usual geometric constructions;
• Ability to drawing an object in an orthogonal or axonometric projection;
• Ability to drawing an object in section;
• Ability to dimension the drawing of a mechanical component;
• Ability to read the drawing of an assembly;

iv. communication skills.
• Ability to communicate with the technical means typical of the design, to specialists and non-specialist interlocutors and within working groups, employing, in particular, the methods of bi and three-dimensional graphic representation for the description of mechanisms, machines and plants.

Prerequisites

None

Contents

1) Unification norms and systems (3h).
2) Multiview projection (3h lesson, 3h tutorial). Central and parallel projections; the orthogonal projections according to the method of the first dihedral and of the third dihedral. The views from non-orthogonal directions to coordinated planes.
3) The sectional views (3h lesson, 6h tutorial). The cutting plane; half-sections and partial sections; conventions of representation of the sections.
4) The dimensioning (3h lesson, 6h exercise). Use conventional dimensioning techniques to describe size and shape; create and read a drawing at a specified scale; correctly place dimension lines, extension lines, angles and notes; dimension circles, arcs and inclined surfaces.
5) Overview of dimensional tolerances (3h lesson). The ISO system of tolerances. Describe the nominal size, tolerance, limits and allowance of two mating parts. Identify a clearance fit, interference fit and a transition fit. Describe the basic hole and basic shaft systems.

Teaching Methods

The course has a total duration of 30 hours, divided into 15 hours of frontal lessons and 15 hours of exercise. The lessons are held in a traditional way through the use of the blackboard and the discussion of schemes, drawings and rules. The exercises consist of graphical tests, related to the course topics, that the students start in the classroom and normally finish at home. The mode of performance of each exercise is illustrated by the teacher and commented with references to the theoretical concepts and regulations.

Verification of learning

Learning the concepts is verified through the evaluation of the graphic tables assigned during the course and through the final exam. To be eligible to take the final exam, all the tables assigned during the course must be delivered and a positive evaluation can be made in each of them. The final exam consists of a graphical representation of a mechanical component with listed orthogonal projections. Suitability is determined based on the student's ability to graphically represent mechanical components according to current norms.
For the evaluation of the exercises and the final test, the following elements are taken into account: a) Clarity in the representation, b) Respect of the rules of representation, c) Correctness of the graphic constructions. These elements contribute equally to the formulation of the final judgment.
