Main themes
  • Methodology in the mechanical workshop and for quality assurance.
  • Basic principles and machine-tools for machining by cutting, erosion and electrical discharge.
  • Basic principles for manufacturing by forming, casting, sintering and welding.
Aims

Regarding the common AA references of the program "Master ingénieur civil mécaniciens", 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.
Evaluation methods

Evaluation of the student personal involvement  during the lab sessions (20%) and written exam assessing the learning outcomes (80%).

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.
Content

The importance of the industry of mechanical production. The challenges in manufacturing.

Machining principles and machine-tool classification

- Machining by cutting : planning and turning, boring and drilling, milling, broaching and tapping.

- Machining by erosion. Rectification.
