Studi di Fabbricazione
Knowledge on fundamental aspects concerning the most common engineering materials, technical drawings, mechanical design and manufacturing processes is required.
KNOWLEDGE AND UNDERSTANDING:
The student will acquire advanced knowledge on the activities that allow to transform the mechanical design of the product in the manufacturing one. This knowledge, by integrating notions acquired in the courses of metallurgy, mechanical drawing, machine design, integrated manufacturing systems and manufacturing processes in mechanics, will form the insights that will enrich the knowledge of the field of manufacturing processes and systems, so that the student acquires a clear awareness of the wider multidisciplinary context of engineeringCAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
In order to address advanced design themes, even of considerable complexity, and treat the innovation and development of new products and new processes through the application of knowledge, the student will have able to generate process plans for manufacturing mechanical components, also by means of computer aided techniques, in view of the reduction of manufacturing inefficiencies. This capacity will appear through a series of professionalising skills, such as: 1. the ability to generate the process plan of a product also assessing the industrial cost; 2. the ability to select the type of computer aided process planning approach best suited to the solution of a specific problem; 3. the ability to use the concurrent engineering approach which involves the teamworkTRANSVERSAL SKILLS:
The resolution of individual and group exercises in lecture room will contribute to improve both the learning skills autonomously and the degree of independent judgment, both the communication skills that also stems from teamwork

MECHANICAL DESIGN AND PROCESS SELECTION. Steps of the mechanical design, project typologies, design tools, selection of the manufacturing processes, process classification, process selection strategies, process selection tools, role of the process cost, economic criteria for the process selection, models for the process cost estimation.
PROCESS PLANNING. Fundamental aspects, process planning activities, route sheet, process tolerances, tolerance transfer, relationship between tolerance and process plan.
COMPUTER AIDED PROCESS PLANNING (CAPP). Definitions, variant CAPP system (group technology, preparatory phase and production phase), generative CAPP system (integration between the CAD and CAPP systems, decision logic), semigenerative CAPP system, comparison among the different CAPP systems.
COST ACCOUNTING. Definitions, cost classification and configurations, cost centers, allocation in cost centers, allocation of general production costs (single and multiple allocation bases), direct costing, make or buy decision.
INTEGRATED DESIGN OF PRODUCTS AND PROCESSES. Characteristics and advantages of concurrent engineering, metodologies for the implementation of concurrent engineering, product development multidisciplinary teams, team typologies, virtual teams.
Development of the examination
LEARNING EVALUATION METHODS
The evaluation is based on an oral exam in which the student must answer four questions chosen among the topics of the course.
LEARNING EVALUATION CRITERIA
The student has to demonstrate, in addition to the ability to deal with the main manufacturing processes used in the mechanical industry, the knowledge and the methodological and technological expertises for the design and development of process plans, their optimization and the determination of the associated costs. Aspects, such as the mastery of technical language and clarity of exposition, will also be assessed. Finally, the ability to properly use the acquired knowledge in solving complex problems must be proven.
LEARNING MEASUREMENT CRITERIA
The ability to independently deal with the topics of the course by applying the methods and tools of the process planning, the clarity of exposition, the mastery of technical language are evaulated.
FINAL MARK ALLOCATION CRITERIA
The four questions asked in the oral test have the same weight in the assignation of the final grade. The minimum score, equal to eighteen points, will be achieved by the students who demonstrate sufficient capacity to answer to all the questions raised. The maximum grade, equal to thirty points with honors, will be given to students who have proven full mastery of the topics, exposed in full autonomy and with appropriate technical language.
