This subject deals with manufacturing systems and automated production systems. An overview of modern manufacturing systems and techniques used in manufacturing facilities is presented. The numerical control of machines is introduced, the design of (computer) Numerical Control (CNC) machine tools, such as turning and machining centers, is explained and fundamentals of CNC programming are discussed. Components related to automated production systems, i.e. industrial robots, as well as measurements and inspection principles are investigated. Basic concepts of manufacturing by means of additive techniques (formerly known as Rapid Prototyping) will be analyzed. The subject will also briefly examine unconventional machining such as Electrical Discharge Machining (EDM), electrochemical machining, chemical milling, ultrasound machining, electron beam machining and laser processing. Moreover, in order to have a comprehensive view of a manufacturing system, students will be guided to address some problems of industrial production management, mainly concerning medium-term programming and scheduling, through presentation of formal models from which the more widespread industrial procedures are derived.

The primary objective of this subject is to provide students with an understanding of manufacturing tools and techniques for implementation of (computer-)integrated manufacturing systems. At the end of the semester, students will: - know the structure of flexible manufacturing systems; - know principles for setting automation levels and process integration in relation to production rates; - know the fundamentals of additive manufacturing; - be able to identify design features that make automation difficult; - be able to describe the basic concepts of numerical control; - be able to identify the basic programming methods used in manufacturing; - be able to compare various robot geometries and working parameters; - be able to effectively manage production flow within an industrial firm, moving pieces, lots, tools, transferring information and orders, monitoring the implementation of operations; - to be able to program the workload for all the centres of production and service included in a company, or better, in a production department; - to schedule the progress of the production job under operation, by verifying the coherence with the plans set be able to identify the most appropriate production technology according to the product requirements.

Knowledge of technical drawing rules and of industrial manufacturing technology with particular emphasis on techniques for metal cutting and machining cycles. It is essential that the student has familiarity with the use of computers.

Modalità di esame: Prova orale obbligatoria;

Exam: Compulsory oral exam;

... The aim of the final exam is to verify the student’s knowledge on modern integrated manufacturing systems. The final exam is basically an oral exam. The exam consists of 5 (five) open questions and covers all the material that was presented during lectures and seminars. Theoretical questions may include the request for drawing/sketches or solving simple problems. The exam starts with 1 (one) open question, that requires a written answer, about management of production systems topics; this first part of the oral exam accounts for 7/30. The second part of the exam consist of 4 (four) open questions about all the other topics; this second part of the exam accounts for 23/30. The final score of the exam is given by the sum of the scores obtained in each of the two parts.
