Mechanical Engineering, Publication in the Diário da República - Despacho nº 14312/2015 - 02/12/2015

5 ECTS; 1º Ano, 2º Semestre, 15,0 T + 45,0 PL + 3,50 OT

Lecturer
- Luís Miguel Marques Ferreira

Prerequisites
Previous kowledge of geometric solid projections, cuts and sections and axonometric perspectives.

Objectives
To enable students to 3D Computer Aided Design (CAD). Advanced dimensioning: dimensional and geometrical tolerances, fittings, surface finish. Machine elements drawings.

Program
1. Dimensional tolerances and surface finish
Introduction
ISO Dimensional tolerance standards
Drawing tolerances
Fittings
Recommended fittings
Control of dimensional fittings
Surface finishing quality

2. Geometric tolerances
Geometrical vs Dimensional Tolerances
Geometrical tolerance symbology
Using geometrical tolerances in practice

3. Technical drawing of welded joints.
Welding processes
Welding symbology
Using welding symbols in practice

4. Machine components.
Connection elements
Mechanical springs
Bearings
Machine components

5. Advanced application in CAD
Solid modelling
Mechanical components data bases

Evaluation Methodology
Students are assessed by individual theoretical-practical work carried out throughout the semester (40%), and by a final work of a practical model (60%).

Method of interaction
After the exposure moments of the theoretical concepts, several practical exercises in CAD will be solved. The SolidWorks® software will be used as a tool to apply the theoretical concepts and to solve practical exercises.

Software used in class
