OVERVIEW

Through an integrated approach that combines theory and practice, the teaching of Manufacturing Technology prepares students to understand production processes, equipping them with the necessary skills to tackle the challenges of modern manufacturing and innovate in a continuously evolving technological context. The course focuses on:

  • Mechanical metrology for the geometric, dimensional, and surface analysis of machined products, where students will learn measurement techniques and the use of measuring instruments;
  • Theoretical models and dynamics involved in subtractive processes, with a focus on turning, milling, drilling, and grinding;
  • Additive manufacturing, examining the operating principles and industrial applications of 3D printing methods for polymers and metals;
  • Joining processes through welding and adhesive bonding, introducing the main techniques, principles, and applications.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides knowledge about mechanical metrology for geometric, dimensional, and surface-finishing analysis of machined products; and metal cutting, considering the basic theoretical models, the main processes and machine tools. The course also provides the fundamentals of additive manufacturing, welding, and adhesive bonding.

AIMS AND LEARNING OUTCOMES

At the end of the course, the student will be able to:

  1. make measurements of length using instruments normally found in the production departments of industries;
  2. understand the main parameters for evaluating the microgeometry of surfaces and the operation of dedicated instrumental apparatus;
  3. employ simple theoretical models (kinematic, dynamic, thermodynamic) to evaluate forces, powers, temperatures as a function of the cutting parameters adopted;
  4. deterministically evaluate tool life;
  5. classify and select tool materials on the basis of their chemical-mechanical characteristics;
  6. understand the operation of the main metal cutting operations and related machine tools;
  7. recognize the main additive technologies and know their potential and limitations;
  8. understand the criteria behind the selection of the most suitable joining method for the material and application.

PREREQUISITES

Elements of calculus and geometry, precisely derivatives, integrals, and trigonometry.

Basic concepts related to material properties, stress, strain, hardness

TEACHING METHODS

Teaching consists of lectures, during which the lecturer will also show physical pieces and films to facilitate understanding of the various aspects of the technologies/processes covered.

Lectures will also be given in the laboratory, where it will be possible to see tools, equipment and machines used in subtractive and additive manufacturing processes and joining methods.

EXAMS

EXAM DESCRIPTION

The exam consists of a written test and an oral test, both held on the same day. Only those who pass the written test are allowed to take the oral test.

The written test focuses on the theory of chip removal cutting and the related machining processes. It consists of an exercise made up of several questions, formulated on the basis of the exercises provided on Aulaweb and covered during lectures. The test is considered passed if the candidate has correctly completed more than half of the questions.

A positive result in the written exam cannot be carried over to subsequent sessions.

The oral test, the outcome of which determines the final grade, consists of one or more questions aimed at assessing the student’s acquired knowledge and may concern any of the topics covered during the course.

The exam topics are those discussed during lectures in the current academic year.

IMPORTANT NOTES:

  1. If the number of registered students is high, a fully written test may be administered, consisting of one calculation exercise and one or more theory questions (open- and/or closed-ended). The rules for carrying out the test and the relevant evaluation criteria will be explained to students at the beginning of the teaching period, published on the course's Aulaweb page, and in any case recalled via a notice on Aulaweb in the days leading up to the exam date.

  2. Students with certification of Specific Learning Disorders (SLD), disabilities, or other special educational needs are invited to contact the instructor at the beginning of the course to agree on teaching and examination methods that, while respecting the learning objectives, take into account individual learning styles and provide suitable compensatory tools.

  3. Registration for the exam must be completed exclusively through the relevant portal at servizionline.unige.it starting 20 days before the exam date and up to 5 days before the exam; late registrations will not be accepted.
    Students who fail to attend the exam without having withdrawn or notified their absence in advance will be subject to the "exam-skipping" rule, meaning they will not be allowed to participate in the immediately following exam session.

ASSESSMENT METHODS

The student in the written test must demonstrate understanding of the topics explained in the lectures and the ability to solve problems starting from the definitions and models studied. The reference topics of the written test are metal cutting and related main machining operations.

In the oral examination, the student's preparedness is ascertained by testing the student's ability to process the information received in the lecture, demonstrating not only mnemonic learning but above all a mature assimilation of concepts.
