Learning outcomes

At the end of this learning unit, the student is able to :
1	Regarding the common AA references of the program "Masters degree in Mechanical Engineering", this course contributes to the development, the acquisition and the evaluation of the following learning outcomes: AA1.1, AA1.2, AA1.3 AA2.1, AA2.2, AA2.3, AA2.4 AA3.1 AA5.4 AA6.1, AA6.2, AA6.3 More precisely, at the end of the course, students will be able to: identify and justify the choice of a manufacturing process that is best suited to produce a commonly used object. explain, based on the knowledge of the underlying physical phenomena, the influence of a manufacturing process on the mechanical properties of the final product. explain the main challenges of each manufacturing process as well as the existing technological solutions. At the end of the course, students will have a first experience of machining of metal parts in a mechanical manufacturing workshop, experimental techniques used to characterize stiffness, hardening, hardness and toughness in a mechanical testing laboratory.

Teaching methods

The whole course is taught in French.

• lectures (introduced with practical problems),
• lecture notes written in French by the teachers (English reference book available),
• solution of exercises in smaller groups,
• laboratories in groups of 3 or 6 students,
• videos showing processes that are not presented in the lab session

Evaluation methods

The evaluation will account for a written exam assessing the learning outcomes as well as the work perpormed during the semester (participation to laboratories and homeworks on moodle).  The formula used to compute the final grade will depend on the mark obtained at the written exam:
- If the mark obtained at the exam is lower than 9/20 (before rounding off), this mark will represent 100% of the final grade.
- If the mark obtained at the exam is greater than or equal to 9/20, this final mark will be a weighted sum of the exam mark (80%) and the assessemnt of the semester work (20%).
If the written exam is organized is distant mode, the professors may complete the evaluation of some students based on an individual oral exam.
