Learning Outcomes
This aim of this course is to introduce the main processes and equipment used in the transformation of metal and plastic materials. Objectives: - Ability to write a preliminary draft manufacturing study for a basic part - Ability to select the appropriate measuring instrument to check the quality of a part

Content
1. Transformation processes of primary molded parts. - Foundry: the main molding processes (fusion and elaboration of metals, sand casting, shell, lost wax, under pressure) and a few rules applying to mold design and part contours - Main processes and equipment for transforming metals: ingot casting, hot rolling, cold rolling, hot forging, drop forging, smelting, sintering, welding (MIG, TIG, etc), cutting, forming. - Main processes and equipment for transforming plastics: properties and common types of plastics, different types of plastic parts, injection, extrusion, blow-molding, rotomolding, calendering, compression, thermoforming, contact molding, projection and filament winding. 2. Dimensional and geometric metrology: Principal measurement and verification instruments, resolutions, measurable tolerance interval, adjustment standards, geometrical tolerance, etc. 3. Functional dimensioning: Analysis of an assembly drawing and calculation of condition dimensions. 4. Manufacturing analysis: Isostatism; drafting of range machining; determine and analyze geometric, technological and economic constraints; select the type of process for the fabrication.

Assessment(s)
N°	Nature	Coefficient	Observable objectives
1	- Functional dimensioning: Starting with the conditional dimensioning, the student must know how to draw dimension chains and calculate the tolerance intervals. - Processes for obtaining primary molded parts: Starting with the technical specifications (design, material and quantity), the student must know how to choose the appropriate process to obtain the primary molded part. - Manufacturing analysis: the student must know how to analyse a drawing and conduct the preliminary draft manufacturing study. - Dimensional metrology: the student must know how to interpret the dimensional and/or geometric tolerance values and select the appropriate verification instruments.	1	Written exam
