Objectives

BACKGROUND

In the present global market, there is an increasing demand for highly sophisticated functions of workpieces at a low cost and a tendency to use both sub-contracting and outsourcing. With those goals, computational systems assume increasingly importance. CAD and CNC systems are major examples of those systems that are progressively been integrated in leader industries. With so high importance in nowadays industry, it is crucial that mechanical engineers know deeply their main characteristics and functions as well as have the ability to handle and process the geometrical and non-geometrical information involved.

SPECIFIC AIMS

Develop the students' capacity to handle geometric and non-geometric information in the development and production areas. To implement computational programs that allow the processing of the information retrieved from software packages common in those areas. To identify and use the diverse characteristics inherent to the drafting programs and numerical control machines (CAD and CNC systems).
Technical skills acquired in this Unit are important for disciplines like, for example, Manufacturing Processes, Introduction to Machine Design and Final Mechanical Project.


PREVIOUS KNOWLEDGE

- Principles and rules for the execution of technical drawings (Technical Drawing Unit).
- Principles and rules for indication of dimensions and related tolerances (Technical Drawing Unit).
- Ability to read drawings of objects in orthographic representation and to make the correspondent pictorial representations (Technical Drawing Unit).
- Basic knowledge about Manufacturing Processes and Product Development techniques (Introduction to Manufacturing Processes and Product Development Unit).
- Knowledge of the main fundaments and paradigms of computer programming.


PERCENTUAL DISTRIBUTION

Estimated percentual distribution for the scientific and technological contents:
- Scientific component: 40 %.
- Technological component: 60 %.


LEARNING OUTCOMES

At the end of the course, the students should be able to:

1) Know usual CAD/CAM systems as well as to use their main functions;
2) Develop definition and assembly drawings using CAD systems;
3) Use CAD systems to accomplish 3D modelling of mechanical systems components and their assembly;
4) Use CAD systems to obtain automatically assembly drawings of mechanical systems previously modelled and definition drawings of their components;
5) Develop computational programs to process information of common CAD/CAM systems;
6) Know the main principles of numerical command systems and associated machine tools;
7) Develop numerical command programs for milling and turning lathe machines.

Teaching methods and learning activities

Exposition of the different themes in theoretical-practical classes with analysis of examples. Several themes are suggested for practical assignments. In practical classes, some particularities are presented and some exercises are suggested, to be done on the computer, to apply the concepts and to the evaluation in class. The last classes are reserved to a more intense support to practical assignments.

Software
