Objectives

To provide the students with complementary knowledge both theoretical and practical, about advanced manufacturing processes .The following technologies will be studied:
- welding and cutting
- metal forming,
- structural adhesives bonding
- electrical discharge machining).

Learning outcomes and competences

It is expected that at the end of the course, the students are able to:

- Understand the principles and concepts required to theoretically analyze the advanced processes studied .

- Identify in which situation the advanced processes studied should be used.

- Design structures obtained by welding, metal forming, adhesive bonding and electrical discharge machining.

Eligibility for exams

Class attendance according to Article 7th  of FEUP evaluation rules.

Calculation formula of final grade

The different topics studid (Welding (W), Metal Forming (MF), Structural adhesives (SA) and Electroerosion (E)) are assessed by a theoretical test (TT) and a practical lab work report  (PR). The final mark (FM) is given by:

 

FM = Average TTs (W, MF, SA, E) * 0,5 + Average PRs (W, F, SA, E) * 0,5

 

A minimum mark of 6 is required in each component.

Examinations or Special Assignments

Not applicable.

Internship work/project

Not applicable.

Special assessment (TE, DA, ...)

Special evaluation in accordance with 9.1 b) and c), 9.2 to 9.4 of Article 9th of FEUP evaluation rules.

Classification improvement

Test to improve final mark in accordance with Article 10th of FEUP evaluation rules.

Students can select part or all the topics when registering for final mark improvement
