Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

This course intoduces to the design of the most usual machine elements. It has also an introduction to metal cuting fabrication processes.
CONTENTS
Intoduction to ISO tolerances. Force determination in a transmission. Preliminary plan of a shaft. Fatigue resistance and criteria. Design of shafts Shaft-hub assembling. Rolling bearing computation. Journal bearings. Gears : spur and helical meshes. Belts and puleys.
Machining technologies: turning and milling operations.

Learning outcomes of the learning unit

After this course, the student will be able to dimension the most used machine elements. This ability will be useful in the integrated project.

Prerequisite knowledge and skills

Prerequisites: Geometry, rational mechanics, elements of strength of materials.
Corequisites: There is a strong relation between this course and the other one, named Processus industriels de mise à forme. It constitutes also a basis for the course entitled Méthodes de fabrication en série and the integrated project.

Planned learning activities and teaching methods

Oral course and exercises which are applications and solution of a desgin project.

Mode of delivery (face-to-face ; distance-learning)

face-to-face course.

Assessment methods and criteria

Part 1: Contnuous evaluation

• The students have to solve several homeworks (mini projects) by groups of two. The assessement is based on the reports.
• Lab reports of the machine tooling tranings.

• Exam includes a part with questions of theory and a part of problem solving (with open books)

• Attendance to the two lab sessions is mandatory to get the credits
• Attendance of 60% to the supervised work sessions is mandatory to get the credits.
• To get the credits, it is necessary to obtain marks greater or equal to 7/20 in both parts. In case of failure, the final mark is the lowest mark of the two parts.

Adaptation of teaching commitments following the COVID-19 pandemic for the May-June 2020 session

Teaching methods implemented : distance-learning

We have been forced to modify the teaching procedure switching from in presence class to remote lecturing using podcast.
Lectures and exercises will be recorded and available to you on the university's website. Discussion forums will be open and virtual classroom sessions will be organized.

Assessment subjects

Everything that has beem covered, either in classes or online is expected to be knowm for the final exam :
- Prelimary draft - Shaft dimensionning - Fatigue - Gears - Bearings - Shaft-hub assembly
Those lessons are not covered and won't be in the exam : - Machining
- Belt and pulleys
- Tolerancing
Projects are taken into account to get the overall grade.

Assessment methods

The exam will take place in a time limited schedule, the wording (including variations specific to each student) will be transmitted electronically. The students will have to scan their answers and send them electronically at the end of the alloted time.
