Subject fundamentals
The teaching aims to provide the basic knowledge on mechanical manufacturing processes, as well as the ability to describe the geometrical and functional features of a mechanical product.
The course consists of two parallel paths, respectively, related to Mechanical Manufacturing (FM Path) and Communication Graphics (CG Path).
The first path presents and discusses the technological and methodological aspects of the most common processes in mechanical product manufacturing, by analysing and classifying them according to their engineering characteristics.
The second path introduces the student to the practical use of graphical rules and symbols adopted in technical drawings. The graphic language is widely adopted in industrial applications to pass technical information from the experts, or between different companies, and often it takes on the value of a contract. Therefore, the knowledge on technical drawings is necessary for every manufacturing engineer.
The two learning pathways are parallel and highly integrated. They support each other towards a unique goal, to guide the student inside the scenarios of mechanical manufacturing and related engineering problems.
Expected learning outcomes
Knowledge of the principles that underlie the mechanical manufacturing processes most commonly used in industrial applications and the related issues, both technical and economic.
Ability to analyse various manufacturing processes from the different viewpoints: the technology (tools and materials used, processing parameters, energy levels), the organization (work cycles), and production costs.
Ability to identify the critical factors and the drivers that are to improve the manufacturing economy and efficiency.
Ability to compare different production processes in a critical way, according to the morphological and functional requirements of products, as well as the expected quality levels and lot-sizes.
Natural and intuitive learning of the technical drawings language to represent and specify simple mechanical components and assemblies.
Ability to use modern CAD systems for managing information related to the technical documentation of products.
Prerequisites / Assumed knowledge
Calculus
Fundamentals of Physics
Good practice in the use of personal computers and office-automation software tools.
Contents
FM Path
Brief look at the history of industrialization under the engineering perspective.
Presentation of the main production processes and their key factors.
Technological features and dimensioning of parameters for the most common mechanical manufacturing processes and related equipment.
Description and analysis of foundry processes, metal forming processes (rolling, forging, stamping, extrusion, drawing, deep drawing, stamping) and material removal processes (turning, milling, drilling, grinding).
Mentions to the specification and verification of compliance, with special reference to micro- and macro-geometrical features, related tolerances (dimensional and geometric), and surface roughness.
Basic concepts on work-cycles methods and analysis (processing times, economic and organizational aspects).

CG Path
Fundamentals of 2D representation of 3D objects and the rules of graphic communication in industrial environments. Outlining of standards and their purposes.
Fundamentals of Computer Aided Design (CAD), aiming to the representation of simple mechanical products by means of a 3D CAD modeller.
Representation rules for standardized and virtual elements.
Outlining of the meaning of call-outs associated to geometrical and functional features.
Delivery modes
Most of the exercises are carried out in computer laboratories (LAIB), with the aid of Office-Automation and CAD software tools.
Practice computations make extensive use of Spreadsheets.
CAD training makes use of a solid modeller software to perform modelling and drafting of simple mechanical components and assemblies.

Assessment and grading criteria

The exam consists of a theory test and a practice test. The evaluation is unique and includes both the learning paths described. It is made of a total of 60 points, 32 assigned to the theoretical part, and 28 to the practical one, respectively. The overall score obtained is resized out of 30 points to expresses the legal value of the examination result.
The theoretical part consists of a questionnaire made of a sixteen questions: for each question, 2 points are assigned in case of a correct answer, 0 points in case of no answer, and 1 point is subtracted in case of a wrong answer.
The practical part in its turn includes the evaluation of two individual projects reports that must be submitted by the student. The reports refers to the laboratory activity carried out by the student under each learning path. A maximum of 14 points is allocated to each project report. The project report is evaluated after an oral presentation given by the student. The student may also submit the project report and give the oral presentation gradually, during practice.
A student may take the test on theory and discuss the project reports at his convenience, even in different calls. The mark obtained for each part is valid within the same academic year. However, if a student comes back to take a test already passed in a previous call the previous result is definitively cancelled and replaced by the new one.
