This ECUE provides knowledge of the various manufacturing processes (Machining, Foundry, Forge, Plastics....).

It also enables you to acquire the classic design rules for mechanical parts, in line with the most common raw material production methods.

On the basis of a specification and/or a definition drawing, students must be able to: choose a manufacturing or assembly process, and draw up the process-related layout.

They must also be able to produce a prototype using traditional machining or a NC "rapid prototyping machine", and check specifications during and after machining. They will also learn about casting and welding during a practical course.

Last but not least, it makes the future designer aware of the problems encountered in the methods office when producing parts from a definition drawing.

This is a basic module on the physical properties of materials and on techniques for dimensioning mechanically simple components or systems.

Material properties are covered using tensile testing, binary diagrams and microstructure.

Component dimensioning involves selecting the most suitable material and defining the geometry to ensure static and fatigue strength. Dimensional analysis can also be used to determine the characteristics of a more complex system, based on experiments carried out on a scale model.

This unit deals with the study of the mechanics of rigid solids. It is the natural continuation of the unit devoted to the kinematics and statics of rigid solids in L1. In this unit, we'll take a dynamic approach and apply the Fundamental Principle of Dynamics. Writing this principle requires knowledge of the external action torsor, studied in L1, as well as knowledge of the dynamic torsor. The latter can be calculated using the kinetic torsor, which for a rigid solid involves the notion of moment of inertia. The main applications studied in this unit concern rigid solids or simple cases of articulated systems of rigid solids. In addition, we will study the special case of contact and friction actions (Coulomb friction) and the Kinetic Energy Theorem.

The first-semester course reviews the grammar essential for oral and written communication(tenses and aspect, asking questions, comparisons and superlatives, passive voice) as well as essential general vocabulary(numbers, measurements, shapes); it also includes an introduction to technical vocabulary(basic building materials, plane engine, bike parts, electronic device) through themed lessons and videos in the field of mechanical engineering.

Finally, numerous activities are offered to promote oral expression skills (presentation vocabulary, simulations, role-playing and board games), so that students are able to describe the specific features, functions and uses of a piece of technical equipment of their choice in an oral presentation by groups of two.

Grammatical aspects are limited to a review of modal auxiliaries.

The vocabulary is much more focused on the various elements involved in the design and operation of different types of heat engines, and on emerging technologies(drones, driverless vehicles, 3D-printing).

Students are also expected to produce a CV in English and practice writing emails in a formal style, so as to be prepared for internship or job-seeking situations where fluency in English will either be necessary or an additional skill.

The practice of expression is always the main objective, with an individual oral presentation at the end of the semester of their second-year project in mechanics.

The aim of this course is to enable students to acquire or consolidate language skills that will be indispensable in their professional lives. Today, English is the language of international communication in the scientific and technical world, both for scientific publications and for conferences and meetings between professionals.

This module is a continuation of the HLME303 module, and introduces the initial analysis tools needed to implement a design approach for mechanical systems. It aims to provide methods for analyzing and dimensioning mechanical systems built on the most widely used technological components.

This module is based solely on lectures and practical work, but maintains a strong interaction with the HLME401 "Technology Project" module, in order to put all the skills acquired into practice on a case study. Initially, the main methods for modeling mechanical systems (functional analysis, kinematic diagrams) will be covered. Then, we'll look at the essential technological components used to guide rotation (plain bearings) or transmit power (belts, gears).

This course provides skills in computer-aided design and mechanism simulation.

In CAD, aspects such as part mode (3D design of a mechanical part), assembly mode (design of a mechanism), drawing of parts or overall drawings will be covered.

The kinematic and dynamic behavior of rigid solid mechanisms will be simulated using CAD/CAM software.

This project enables students from different educational backgrounds to apply the theoretical and/or technological concepts they have learned previously and in other modules of the course, to the study of a proposed mechanical system or a system of their choice (after validation).
