Aims

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.

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.

Evaluation methods

Evaluation of the student personal involvement  during the lab sessions (15%) and written exam assessing the learning outcomes (85%).

Teaching methods
  • 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 sessions.
