| Contents | The course provides the basic skills necessary for the design, use, and management of measurement chains for detecting mechanical and thermal quantities. The main topics include: fundamentals of the concept of measurement; application of measuring instruments in various fields, particularly in control systems; the concept of measurement and uncertainty; configuration of a measuring instrument; functional block diagrams. Characteristics of measurement chains and signal analysis. Static calibration and static characteristics of an instrument: uncertainty, sensitivity, linearity, repeatability, threshold, resolution, hysteresis, dead zone, scale readability, input impedance; uncertainty in indirect measurements; dynamic characteristics, generalized mathematical model of a measuring system; zero-order, first-order, and second-order instruments; response to canonical inputs; response of a general instrument model to periodic inputs; response of a general instrument model to transient inputs; basics of analog and digital signal analysis, spectra, correlations, transfer functions; main electrical and electronic components of measurement chains for data manipulation, transmission, acquisition, processing, and presentation. Classical systems for mechanical and thermal measurements. Classical systems for measuring lengths, displacements, deformations, solid-body velocities (translation and rotation), fluid velocities, accelerations, flow rates, forces, pressure, acoustic noise, heat fluxes, and temperature.

In case of difficulties (regarding the detailed course syllabus or for consultations), please contact the instructor by email at roberto.marsili@unipg.it, specifying your first name, last name, enrolled course, and degree program. |
| Learning verification modality | The exam consists of an oral test and/or a written test. Oral test consists on an interview of about 45 minutes long aiming to ascertain the knowledge level and the understanding capability acquired by the student on theoretical and methodological contents as indicated on the program. The oral exam will also test the student communication skill and his autonomy in the organization and exposure of the theoretical topics. |

| Contents | L’insegnamento fornisce le competenze di base necessarie alla progettazione del ciclo di fabbricazione di un componente meccanico. I principali contenuti riguardano i processi manifatturieri per metalli, tipicamente applicati a leghe a base ferrosa ed alluminio. Sono trattati processi manifatturieri classici come i processi per fusione, deformazione plastica ed asportazione di truciolo. Processi di giunzione basati su saldatura per fusione. Sono trattati anche processi manifatturieri innovativi, quali la manifattura additiva. |

| Educational objectives | The teaching concurs to train the student in the technical-operational aspects of manufacturing technologies, provides basic techniques and tools for the design of fabrication cycles, including multi-process cycles for the fabrication of mechanical components and assemblies. The main objective of the teaching is to provide students with the basis for manufacturing process evaluation and planning, capable of translating the design contained in a drawing (CAD) into a physical object that meets design specifications. The main learning outcomes will be: 1) Knowledge of the basic principles of applied manufacturing technologies in the field of mechanical engineering. 2) Knowledge of the main manufacturing technologies based on the principles of solidification, plastic deformation, chip removal and additive manufacturing. 3) Ability to interpret indications of dimensional, geometric, and surface finish tolerances and identify correct technological operations. 4) Ability to plan a sequence of operations and steps suitable for making a mechanical component from a semi-finished or solid part. 5) Ability to dimension the process parameters and geometric quantities of the tools required for the manufacturing cycle. 6) Evaluate the effects of parameters on the manufacturing process. |
| Prerequisites | In order to understand and be able to apply most of the techniques described in the teaching, prior knowledge of Technical Drawing and General Physics is necessary. |
| Teaching methods | The course is organized into: - classroom lectures during which the topics covered in the course are addressed; - laboratory and computational exercises consisting of planning manufacturing cycles per part for which technical drawings are provided. The entirety of the teaching materials used during the course - e.g., lecture slides, performed and proposed exercises, tables, videos and other content - is available through the Unistudium platform. |
| Other information | More information is available through the dedicated Unistudium page. The lecturer is available for consultations at the end of each class; consultations with the lecturer in person or through the Microsoft Teams platform can also be arranged at other times. |
| Learning verification modality | The exam consists of two parts: - A written multiple-choice test including both computational exercises and theoretical questions on the entire landscape of course topics. - An oral test. The tests are aimed at ascertaining knowledge of the topics covered. The oral test is particularly aimed at ascertaining the student's ability to correctly plan manufacturing cycles, highlighting critical issues and approaches for their resolution or mitigation. Unless otherwise advised, the two tests are held on the same day, one following the other. The final grade is the arithmetic average of the grades obtained in the two tests. To pass the exam, however, it is necessary to obtain a score of at least 15/30 in the written test. |
