Computer Aided Production Engineering
Master of science-level of the Bologna process in Mechanical Engineering - Torino
Master of science-level of the Bologna process in Engineering And Management - Torino
The main aim of the subject is to examine integrated techniques of the design and process utilised in the manufacturing to reduce time to market. Fundamentals is the availability three-dimensional CAD model, in order to exchange of date the standard formats are described. The link between computer aided design and computer aided manufacturing is discussed. Moreover, the additive manufacturing technology are describe to produce complex functional parts, directly without furthermore processing. Finally, to complete the product and process integration, the CAPP systems are discuss to planning process with computer aided.
Expected learning outcomes
The subject would provide students a deepen knowledge of the modern technologies of computer aided manufacturing, developing the skill to select the suitable manufacturing strategy depending on product, manufacturing amount and time compression techniques to reduce product and process development time.
The student will be able to make assessments on the development and manufacturing strategies, to formulate and develop new approaches to achieve greater integration to reduce time and increase the competitiveness of manufacturing companies.
At the end of the course, the student will have to:
1. Know the systems and computer-aided manufacturing software applications on the market;
2. Identify the time compression techniques to reduce the time of product / process development
3. Use additive manufacturing techniques and reverse engineering;
4. Apply these techniques to practical cases.
Prerequisites / Assumed knowledge
The student taking the subject should have technical knowledge of industrial design, three-dimensional CAD modeling techniques, manufacturing technologies in particular burr removal machine and manufacturing cycle. It is necessary that the student have the confidence with the use of computer.

Assessment and grading criteria
The final exam is in the oral form and is shared in two sections: the first one includes the topics of the lectures and the second focuses on the discussion of the essay, corrected by the teacher. At every stage of exam, according to the answers given by the student a grade is assigned. The final grade will be the average of the two grade above, if each is sufficient.
