OVERVIEW

Manufacturing technology module introduces students to the fundamental topics for the study of the production processes used by manufacturing industries, specifically metal cutting processes.

AIMS AND CONTENT

LEARNING OUTCOMES

This module provides the tools to study mechanical metrology (including surface micro- and nano-geometry), metal cutting, considering cinematic and dynamic theoretical models, the machine tools, their kinematics, structures, the generation of forms, the transducers and the basic principle of the machine tools numerical control.

AIMS AND LEARNING OUTCOMES

Active participation in the proposed training activities (both lectures and laboratory activities) and individual study will enable students to:

• know the main tools used in the field of mechanical metrology, applied in manufacturing processes.
• apply metrological knowledge in practical laboratory examples.
• employ simple theoretical models (kinematic, dynamic, thermodynamic) to evaluate, under orthogonal machining assumptions, forces, powers, temperatures as a function of the cutting parameters adopted.
• deterministically evaluate tool life.
• classify and select tool materials on the basis of their chemical-mechanical characteristics.
• understand the characteristics of the main machining operations for machining, plastic deformation and foundry, including the main elements of calculation.

The student should also acquire the ability to choose possible production solutions for a given part, identify the main process parameters and their effect on the characteristics of the part, evaluate possible production problems, and acquire general knowledge of machine tools and production system management. To complete the theoretical training, the course includes one or more visits to laboratories and/or companies.

TEACHING METHODS

Teaching consists of theory lectures, application examples and laboratory metrology exercises. Optionally, students may participate in one or more training activities that will be organized through seminars and company visits.

SYLLABUS/CONTENT

EXAMS

EXAM DESCRIPTION

The exam consists of:

• A metrology training activity conducted during the lecture period
• A 20/30 minute written test that if passed with a grade greater than or equal to 18 allows access to the oral test,
• an oral test of 2 questions.

The written test only applies to a single examination.

There will be 3 examination calls available for the winter session (January-February) and 3 examination calls for the summer session (June, July and September). No special calls will be granted outside the periods specified in the course regulations, except for working students enrolled part-time.

ASSESSMENT METHODS

The assessment is made through a training activity, a written test and an oral examination.

The student in the written test must demonstrate that he/she understands the topics explained in the lectures and solve problems from the definitions and exercises carried out in class. The reference topics of the written test are: orthogonal machining, tool life, quality.

The oral examination consists of a test of what has been learned and the ability to critically employ the models and concepts covered in the teaching. Topics not covered in the written test will also be explored in depth by oral interview.
