General description | This subject studies the main manufacturing processes of metal casting, polymer processing, plastic deformation of metals and joining processes. It is mainly focused on the forming of metal and plastic components in industrial environments. The fundamentals and characteristics of the manufacturing processes and their relationship with the final structure of the materials and mechanical properties of the parts obtained are studied. | |||||||||||||||||||||||||||||||||||||||

Methodologies |
Description | |
Problem solving, classroom exercises | In order to fix the knowledge, the teacher will dedicate some hours to the resolution of exercises and problems. A series of problems will be proposed to be solved by the teacher and others to be solved by the student. |
Seminars | A seminar will be held, given by the CEDINOX group (Association for Research and Development of Stainless Steel), where the study of stainless steel and the most suitable manufacturing processes for this type of materials and their applications will be studied in depth. |
Assignments | A team work will be carried out on a real case of manufacturing a product or component. For this purpose, a company whose activity is related to the manufacture of a part or product must be visited. Students must submit a report of the work and make an oral presentation of it. |
Laboratory practicals | In the practical sessions (groups B3), students will work with industrial equipment and specific software used for different manufacturing processes. During the development of these practices or at the end of them, students will perform a practical exercise or answer a questionnaire to evaluate the use of these practical sessions. Attendance to the practical sessions is mandatory to obtain a grade in this part. |
Lecture | The lectures will have an eminently theoretical content and will address the fundamental concepts of the subject with a technological approach. During these sessions, the professor will use slides that he will leave for the students beforehand on the Moodle platform. |

Assessment |
Description | Qualification | ||
Laboratory practicals | Students who have attended the practical sessions will be evaluated by completing a questionnaire or practical exercise. | 15% | |
Assignments | A team work will be carried out on a real case of manufacturing a product or component. This work will be evaluated according to a rubric that will be available to the students. The work may be reviewed with an anti-plagiarism program that can perform checks between the work of the students of the current and previous call and against external sources. If plagiarism is detected, the work will not be graded. | 20% | |
Objective short-answer tests | For the assessment of theoretical knowledge, two tests will be given during the semester. The tests will consist of short answers to theoretical questions or multiple-choice questions. | 40% | |
Practical tests | For the evaluation of the applied knowledge, two tests will be carried out during the semester. The tests will consist of solving problems and practical exercises. | 25% | |
Other comments and second call | |||
FIRST CALL: To pass the course it will be a necessary but not sufficient condition to obtain a minimum grade of 3 out of 10 in each of the tests carried out in the block "Objective short-answer tests" and "Practical tests". In case of reaching the minimum in each of these tests, the final grade will be the result of the sum of all the grades obtained throughout the course in all the activities carried out. The result must be equal or higher than 5 out of 10 to obtain a passing grade or higher. The final grade of the students who have not reached the minimums to pass the 1st call, will be obtained from the sum of the block "Objective short-answer tests" and "Practical tests" discarding the grade of the rest of the tests. SECOND CALL: "Objective short-answer tests" and "Practical tests": In case of having reached the minimums in the tests taken in these blocks in the first call, the student will keep his grade for the 2nd call and will only have to take the exam of the tests in which the minimums have not been reached. "Laboratory practicals" and "Assignments": If the Laboratory practicals and/or Assignments have been carried out in the continuous evaluation, their grade will be kept for the 2nd call. In case of not having done them, the student will not have the option of grading in that part . |
