B6369 - Manufacturing Processes for Nautical Applications

Learning outcomes

The student will learn the basic principles of Design for Manufacturing, Design for Assembly and Concurrent Engineering methods for the Nautical sector. Selection criteria for production processes based on the products properties and the production cost will be studied. Finally, application and programming skills will be acquired using CAD-CAM systems for flexible automation.

Course contents

 

The course aims to provide general training on materials and manufacturing processes currently used in the production of nautical components.

1. Materials

In the first part of the course, metallic and natural materials most commonly used for the manufacturing of boat components will be studied. Their main properties and characterization methods will be described. In detail:

• Metals
• Natural materials (wood)
• Properties of materials and designations
• Materials characterization. Physical-chemical properties, mechanical and technological properties, corrosion resistance.
• Tensile Test, Hardness Test, Resilience Test, corrosion tests, accelerated aging tests 
• Heat and surface treatments.

2. Production processes

• Production systems, classification of production processes and criteria for process selection
• Foundry processes
• Metal forming processes:
• Joining processes
• Machining processes: fundamental aspects and CAD-CAM programming
• Finishing and polishing processes
• Advanced technologies: Laser processing, additive manufacturing, Water jetting, Thermal cutting and plasma cutting, Electro-discharge machining (EDM) and wire cutting (WEDM).

Readings/Bibliography

Powerpoint slides available on UniBo repository.

Teaching methods

Lectures based on powerpoint slides with in-depth analysis at the blackboard; exercises and analysis of industrial cases.

Assessment methods

The exam aims to verify the achievement of the Learning outcomes:

· knowledge of the materials used in nautical sector;

· knowledge of advanced processing technologies;

· ability to analyze and propose  technological cycles, in relation to the adequacy and compatibility of the technologies identified to obtain specific requirements on the finished product;

· team working skills in carrying out the study.

Preliminary or after the final test, the students must discuss the team-working project on the selected technology. The final score is an average of team working project score and written test.

At least, 5 evaluation session will be realized through the accademic year.
