Subtractive and Additive Manufacturing

Recommended Prerequisites

Technical drawing. Computer Aided Design (CAD). Materials Science. Engineering Materials. Elasticity and plasticity. Mechanical Behaviour of Materials. Heat and Mass transfer. Manufacturing Processes.

Teaching Methods

The classes take place in theoretical and theoretical-practical regime. In theoretical classes the concepts and technologies associated with concepts are presented. In practical classes some more aspects of technologies using audio-visual and performed application exercises in the room and laboratory are detailed. Students have an active participation throughout the formative process, being asked to present and discuss the solutions found for the problems and distributed work. Practical classes are also complemented with visits to companies.

Learning Outcomes

The aim of the curricular unit is to provide skills considered complementary in the area of subtractive and additive technologies, in order to provide the student with autonomy in the design and manufacture of mechanical components, using these technologies.

At the end of the curricular unit the student should: (1) know the most usual CAD/CAM systems and know how to use their functions; (2) know the basic principles of numerical control systems and the associated machine tools; (3) develop numerical command programs for machining and additive manufacturing operations.
