Machine Design prepares engineering students to design and identify how a system consisting of fixed and moving parts ? the so?called ?machine? ? can convert and transmit the energy in the best way to be suited for a specific application. By the end of the semester the student will be able to deal with functional requirements and design specifications, to use a variety of existing mechanical components and devices and their most appropriate domain of application, to determine the shape and size of the machine components and to predict their strength and life, to choose the materials best suited for the application, to take into account up-to-date standards or codes of practice and technological constraints, to employ some suitable analytical models and numerical tools, to deploy the whole design process, and to be able to take a responsible decision based on the best current practice.
This subject contributes to the education of mechanical engineers, as they are required to deal with several functions, at work, from design to production, from operation to maintenance of mechanical systems and machines, in many technical domains as transportation systems, manufacturing processes, energy production, conversion and storage, in aerospace, industrial, automotive, nuclear, chemical applications and even others. Those targets of employment require a good knowledge of machine elements, of fundamentals of design approaches, as well as of technical standards and tools. Machine Design prepares the engineering students to design and identify how a system consisting of fixed and moving parts (the so-called machine, being able to perform work) can convert and transmit the energy in the best way to be suited for a specific application. By the end of semester, the student will be able to deal with functional requirements and design specifications, to use a variety of existing mechanical components and devices and their most appropriate domain of application, to determine the shape and size of the machine components and to predict their strength and life, to choose the materials best suited for the application, to take into account the up-to-date standards or codes, as well as best practices and technological constraints, to employ some suitable analytical models and numerical tools, to deploy the whole design process, and to be able to take a responsible decision based on the best current practice.
Foreword: Machine Design engineers/analysts are typically tasked with designing structural and mechanical components of machines (bolted connections, transmissions, bearings, shafts, couplings, springs, etc.) and the assembled systems which these components are part of. At the threshold professional level the Machine Design engineers/analysts must be able to analyse an existing machine component or design modification to meet given requirements: they apply methods and use existing software according to given specifications and under the supervision of a senior engineer. At the standard professional level the Machine Design engineers/analysts must be able to produce new designs for machine components or systems to meet specified requirements: they choose the appropriate analytical or numerical methods and use them under their own responsibility. As a consequence this Subject Module aims at competences at the threshold level through the study of a selection of representative and complementary classes of problems each requiring a specific treatment (Contents 1 to 5), and introduces students to the standard level by exposure to a semester-long Technical Project where an assembled machine is examined and design alternatives are proposed and compared. In order to develop the required competences applicable to any type of mechanical structure or machine, students are required, by the end of this subject module, to show achievement of the following main points of knowledge: - know the theory, and the experimental evidence in support, which underpin the mathematical models of mechanical components - identify the critical weak points for strength, according to all possible failure mechanisms, evaluate uncertainties and apply the appropriate safety coefficients, assess whether the stresses are admissible - analyse an existing machine component to check whether it meets given requirements - identify the governing parameters in a component design, define the shape and size of machine components, know how to introduce appropriate design modifications to improve strength and life or to upgrade specifications; this may extend, in some selected cases, to propose new designs for machine components or systems while taking full responsibility to that - analyze the mechanical performance of interacting components assembled in a machine, i.e. kinematics, exchanged loads and stresses by means of analytical methods and modelling techniques, whether analytical or numerical - identify among technical solutions compatible with the state-of-art of the availble technologies a suitable architecture and/or mechanism to convert and transmit energy to be exploited in the design operation - know their theoretical background of the relevant standards, codes and regulations which are used in the field and skills: - correctly read the mechanical drawing of a machine or its subsystem, identify parts and their assembly, understand constraints taking account of mechanical and thermal stress conditions, functional requirements, material strength - be able to propose more ways to assemble components into a mechanical system to achieve the same function - be able to apply the theory and the mathematical models to component and machine designs - indentify which data are needed to a design, and where they can be found - deploy the appropriate reasoning to approve a design, and be able to take a responsible decision based on evidence - know how theoretical or numerical predictions or models can be checked with appropriate experimental tests - be able to present, in both oral and written forms, a clear and well-structured set of relevant considerations on design assumptions and results - be able to read, understand and comment technical material from books, manuals and any other source.
Engineers and analysts are typically asked to perform the design of structures, mechanical components of machines (bolted connections, power transmissions, bearings, shafts, couplings, springs, etc.) and of assembled systems. Nevertheless, two levels of skills can be identified. At basic professional level, machine designers and engineers must be able to analyse an existing machine component and to modify the design to fulfil some given requirements. They are used to apply methods and tools (even software) under the supervision of a senior engineer, by resorting to a typical “design by rule” approach. At standard professional level, machine designers and engineers must be able to perform new designs of machine components and systems, to fulfil specified requirements. They use suitable analytical or numerical methods and are responsible for product liability, as they implement typically the “design by analysis”. Therefore, this module deals with a selection of representative and complementary classes of design problems. Each topic requires a specific development. Students are asked to develop a semester-long Technical Project. It consists of a typical test case of mechanical design, which is analysed in detail. Some design solutions are proposed and compared. In addition, some exercises are proposed to students to be solved and added to the technical report. To develop some useful competences applicable to any kind of mechanical structure or machine, students are required, by the end of this module, to achieve the following targets of knowledge and related capabilities. Knowledge: [A] to know the theory and the experimental approaches, which underpin the mathematical models of mechanical components; [B] to identify the critical weak points for strength, predicting several failure mechanisms; [C] to evaluate uncertainties and to apply appropriate safety coefficients against collapse; [D] to analyse a machine component and check whether it fulfils the standards' requirements; [E] to identify the main design parameters of a component, to define the shape and size of machine elements. [F] to know some typical and theoretical background defined by technical standards; Capabilities and skills: [A] to modify a mechanical design, to improve the system strength and to increase its life or to upgrade specifications; [B] to predict the performance of components assembled into a machine, by investigating their kinematics, loading conditions and stresses, through analytical and numerical methods [C] to identify among several technical solutions those compatible with the available technologies and a suitable layout to convert energy and transmit power; [D] to interpretate mechanical drawings of machine and systems, by identifying parts and components; [E] to impose suitable constraints, to bear mechanical and thermal stresses; [F] to propose suitable assemblies of machine elements to satisfy requirements; [G] to apply mathematical models to component and machine design; [H] to identify and set relevant data needed to design mechanical systems; [I] to approve a design and be able to take responsible decision based on evidence; [J] to validate theoretical or numerical models through some experimental tests; [K] to present, in oral and written formats, a clear and well-structured set of remarks describing the design targets, assumptions and results; [L] to read, understand and analyze technical literature, including handbooks, notes and standards. Those knowledges and capabilities are formed during the course and then checked during the exam, in written and oral tests. They are aligned with the targets defined for the Master Degree in Mechanical Engineering (Modello Informativo SUA-CdS 2022-2023, quadri A4b1 https://didattica.polito.it/pls/portal30/sviluppo.vis_aiq_2013.visualizza?sducds=32053&p_a_acc=2023&tab=sA4b1 e A4b2 https://didattica.polito.it/pls/portal30/sviluppo.vis_aiq_2013.visualizza?sducds=32053&p_a_acc=2023&tab=sA4b2 ). They include the knowledge of design methodologies applied to the main machine elements, with respect to their strength, according to technical standards, and even the capability of effectively working in technical teams composed by several professionals.
Attendance of this module requires fluent spoken and written English as a necessary pre-requisite: all lectures and tutorials, and all study material will be in English. Standard mathematics for engineers is sufficient. It is assumed that students taking this subject-module already have knowledge and understanding of the strength of materials principles; in detail, they know and use strain and stress tensors and their principal properties, preferably in matrix notation, their graphical representation through Mohr circles, the two and three dimensional behaviour of elastic materials, the constant force design criteria of brittle and ductile materials (maximum normal stress, maximum shear stress or Tresca, maximum distortion energy or Von Mises). Moreover they master the mechanics of forces and the dynamic of rigid bodies; as to deformable bodies, they master bar and beam problems for tension, bending and torsion, and know ensuing the cross section stress distribution. It would be an advantage if students would have a prior knowledge of basic machine design elements, technical drawing and elements of mechanical machining technologies.

Credits 8, 81 classroom hours (40.5 lecture hours, 40.5 tutorial hours). The total study load for this subject is 200 to 240 total hours, i.e., 25 to 30 hours per credit. This includes classroom hours, self study, completion of tutorials at home and reporting. Class hours are equally shared between theoretical lectures and application tutorials, in order to achieve a balance between knowledge and skills. The subject is organised to allow students to progress incrementally in the development of their knowledge and skills under expert supervision. All lecture materials will be made available on the subject unit website before the class activity. Students are urged to download or print them so to have them at hand to take notes. Lectures on a section of the material will be followed by specific tutorials, where students are required to apply knowledge to working context problems. The tutor will provide organised materials and frames for solutions. However, the students will solve the proposed tasks themselves in small groups (max 3 students) Moreover, there will be a semester-long project, the so ? called ?Technical project?: in order to enhance problem solving capabilities, encourage independent thinking and develop professional reporting skills. For each task, each group of students will produce a final report. The set of all reports will be examined during the final exam. Students are asked to work cooperatively in a small group. The tutor will assist the groups during the tutorial class hours, supporting students in their learning progression and clarifying their doubts. Attendance to both lectures AND tutorials is strongly recommended, this being vital to achieve the expected learning outcomes. The teacher and the tutor are available weekly during the teaching period in order to meet students for consultation; please contact them by e-mail. Tutorials may benefit from using EXCEL or MATLAB. Writing reports with editing software is not required. although a clear and professional presentation is strictly required. Drawing tools (pencil, compass, scale rulers...) are necessary.
This module provides 8 credits, corresponding to 80 hours, equally divided into 40 of lectures, and 40 of tutorials). The study load for this subject is from 200 to 240 hours, including classes, personal study, completion of tutorials at home and reporting activity. - The lectures describe the theoretical issues of this disciplines and related technical standards as well as their relation with manufacturing processes and technologies. - The tutorials propose several exercises and a more complete project referred to as “Technical Report” dealing with the complete analysis of a mechanical system, representing a real industrial or professional application. Classes are equally shared between lectures and tutorials, to allow students learning by doing, by applying theoretical concepts to some simple examples, exercises and test cases. This module is organised to allow students to gradually develop their knowledge and skills, under the experts' supervision. The whole lectures and tutorials’ material is available on the course website. Students can download and print all the shared material in advance, to add notes during classes. Each section of lectures is almost immediately followed by some specific tutorials. Students are required to apply knowledge to some practical problems, to master the theoretical issues. Each tutor provides the organised material and some frames for solving several proposed exercises. Students are required to solve the proposed tasks themselves, being organized in small groups including three persons. The semester-long project, i.e. the so-called “Technical Report”, is aimed to enhance the problem-solving capabilities of students, and to encourage their independent thinking and to develop professional reporting skills. This Technical Report focuses on the structural analysis of a given mechanical system (different each academic year), including all the main elements of Machine Design. Tutors describe the technical problem object of this analysis, during the tutorials, and show a sort of roadmap to be applied to perform the investigation. Each group of students performs then the structural analysis of a given constructive solution, to check the safety margins applied. Other solutions are even investigated, to propose an optimization of the proposed layout or the selection of more suitable materials and components. In this activity, students apply the theoretical issues learnt during the lectures, implement the rules of technical standards, draw the machine elements to understand in details the system behaviour and architecture, respectively. They are even trained in presenting the whole activity performed. For each task, each group of students produces a final report. The set of all reports will be examined during the final exam. Students are asked to work cooperatively in the small group of three persons already set up to solve the proposed exercises. The tutors assist the groups during the tutorials, supporting students in their learning progression and clarifying their doubts. Attendance to both lectures and tutorials is strongly recommended. This is essential to achieve the expected learning outcomes. The teacher and the tutors are available during the teaching semester, to meet (directly or remotely) students for consultation (please contact them by e-mail to agree about a meeting). Tutorials may benefit from using EXCEL or MATLAB tools. Writing reports with editing software is not required, although a clear and professional presentation is strictly required. Drawing tools (pencil, compass, scale rulers...) are strictly necessary.

Exam: Written test; Compulsory oral exam; Group project;
Achieved learning outcomes will be assessed by means of a final exam. This is based on an analytical assessment of student achievement of the expected learning outcomes above described. In regular conditions, being not affected by restrictions induced by the health emergency due to pandemia, which recently occurred, the examination is composed by two main sections: written and oral tests. a) Written test (first day of examination): -) a test, 2 hours long, with closed books, no didactic material allowed, is composed by three questions. Two are related to the theoretical issues of lectures (topics are listed above and contents are those of didactic materials shared via website) and verify the knowledge of theory. One exercise completes this test to assess the problem solving skills of students (this is similar to the exercises proposed during tutorials). Each question scores up to 8 marks. To attend the oral exam, the student must score in the written test a minimum of 12 marks, and particularly a minimum of 4 (50%) marks for each question. The maximum score provided by the written test is 24. This test mainly verifies the following knowledges: [A], [B], [C] and the achievement of these capabilities: [B], [D], [G], [H], [J]. b) Oral test (second day of examination, after the written test and score publication) includes: -) a review of written test, to show the student grading criteria and to receive any student's appeal, supported by appropriate explanations (no score for this step); -) a technical conversation with the lecturer, to verify the student's ability to deal responsibly with a mechanical design problem, by identifying an appropriate application of the acquired knowledge, This part is strictly related to contents of theory, explained during the lectures and documented by slides (up to 4 marks) -) a discussion with one tutor, to whom the student will submit the full set of tutorial reports. The tutor will investigate the effective personal achievement of skills and know how, based on contents of reports. This part is strictly related to the activity performed during tutorials, including the development of the Technical report and the solution of the proposed exercises. (up to 4 marks) This oral test mainly verifies the following knowledges: [D], [E], [F] and the achievement of these capabilities: [A], [C], [E], [F], [I], [K], [L]. The final score is composed by the score of written test, added to the score of the two interviews performed during the oral test. The maximum score is 30/30. in case of exceeding result, the teachers will assign the "cum laude".
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
