Learning objectives

This course aims to provide the knowledge and skills (i.e., the ability to apply knowledge) necessary to study manufacturing processes and systems, together with assembly of components and industrial products.
The primary objective of this course is to develop skills that allow the student to understand processes involved in the production of a mechanical component within an industrial context based on information within the technical drawing.
To this end, it is essential to obtain knowledge relating to the following topics:
Information contained within the technical drawing in terms of workpiece geometry, materials, surface finish and form and positioning tolerances;
Issues relating to obtaining a certain level of precision during processing and knowledge of the measurement devices necessary for quantification of precision;
Foundry and plastic deformation intended as primary forming processes;
Reversible and irreversible joining techniques;
Machining and machine tools.
The ultimate goal of this course is for students to obtain skills relating to manufacturing of a mechanical component and development of a correct (rational and economical) machining sequence plan that comprises all necessary steps for production.
To this end, it is necessary to develop the following skills:
Study of the primary forming process of a component;
Choice of the raw material (in terms of dimensions, material and primary production process) for machining of a component;
Identification of the sequence of operations necessary for production of the component;
Positioning and reference of the component with respect to the machine tool with appropriate fixtures.


The ability to understand and interpret the information contained in a technical drawing (views, sections, dimensions and tolerances) is considered a fundamental prerequisite for successfully understanding lessons and passing the final exam.
Further prerequisites include basic knowledge relating to engineering materials (metals, alloys, polymers).
To this end, it is considered essential to have passed the DISEGNO E TECNOLOGIE DI PRODUZIONE course.

Teaching methods

The student will acquire advanced knowledge relating to various manufacturing processes employed to transform a project into a finished product. This knowledge, integrating notions acquired in the courses of design, chemistry and production technology, will form a solid foundation upon which students can acquire a clear understanding of the workings of a generic production department.
To become independent in planning the manufacturing of a component and taking care of innovation and development of new products and processes, the student will be required to be able to specify the sequence of operations necessary to produce mechanical components with a view increasing efficiency and process quality.

Assessment methods and criteria

Course assessment consists of written exam.

The written exam has a maximum duration of 1,5 hours and consists of a technical / practical exercise comprising full specification of the sequence of operations for manufacturing a mechanical component based on a dimensioned technical drawing. The goal is to verify the candidate’s skills in choosing the most effective and economically appropriate production cycle.
The remaining part of the exam is aimed at verifying the candidate's competence and knowledge in discussing any topic covered during the course and, if necessary, providing an appropriate graphic representation.
