Learning objectives
At the end of the course students will have acquired knowledge and skills related to CAD/CAM tools and systems and related methodologies, technologies and functionalities, as well as unconventional manufacturing processes such as laser materials processing, additive manufacturing (AM), ultrasonic machining, water jet cutting, abrasive water jet cutting, electrical discharge machining, friction welding and electrochemical machining. Teaching will be carried out according to a systematic approach based on the modelling of these processes, in order to allow interpretation and understanding of the laws and mechanisms on which they are based. For each unconventional manufacturing process, the advantages and limitations compared to traditional machining and potential in the production of specific components will be analysed.
Prerequisites
Physics, Chemistry, Mathematical Analysis, Design, Manufacturing Technology
Course unit content
The objective of this course is to study CAD/CAE/CAM technologies and systems (Computer Aided Design/Computer Aided Engineering/Computer Aided Manufacturing) for product design, as well as planning and programming of production and manufacturing processes for mechanical components. The course includes the study of unconventional manufacturing technologies for which the use of computer numerical control (CNC) is essential: laser materials processing, additive manufacturing (AM), ultrasonic machining, water jet cutting, abrasive water jet cutting, electrical discharge machining, friction welding and electrochemical machining.
