Introduction to Manufacturing Technologies

Materials – materials science and engineering fundamentals

In the theoretical classes, the expository and inquiry-based methods are used. In the theoretical–practical and practical classes, students become familiar with the main manufacturing operations of metallic materials by chip removal machining and welding, using different mechanical measuring instruments.

The Laboratory Component has the following operating conditions:

• Use of a lab coat and appropriate personal protective equipment (PPE) suitable for the activity being carried out;
• Compliance with the mandatory laboratory safety rules.

C1 – To know the materials classes and materials’ life cycle.

C2 – To know and understand the working principles of the main processes available for the manufacturing of components and the main advantages and limitations of each one.

C3 – To gain critical thinking and ability to analyse problems in order to identify, among these processes, the most suitable for the manufacture of a particular component that has specific requirements for use with a biomechanical purpose.

C4 – To perform fundamental operations of some of the manufacturing technologies, in a laboratory environment.

CT1 – To perform teamwork in a laboratory environment.

CT2 – To acquire abstraction and data interpretation skills, to achieve alternative solutions to a problem.

The assessment for the course unit may be carried out through periodic assessment or a final examination. The final grade reflects a weighting of 50% for the mastery of theoretical content and 50% for the comprehension and application of practical content, as taught in class.

The first written assignment (or midterm exam) is held halfway through the semester and covers the content effectively taught up to that moment, in both theoretical and practical classes.

Should the student fail to achieve a passing grade in the continuous assessment, they will automatically transition to the final examination assessment method. The final examination takes place during the periods defined by the academic calendar and encompasses all content taught throughout the semester.

Periodic Assessment:

Two Written Tests (PE1 and PE2), with a minimum passing score of 8.0 out of 20 in each.

Final Grade, FG = PE1 (50%) + PE2 (50%)

Approval in the course unit requires a final grade (FG) of 9.5 values out of 20,

Assessment by Examination (Normal, Recourse, Special and Monthly Periods):

Written Examination (PE) with a minimum passing score of 10 out of 20.

Final Grade, FG = PE
