Teaching Methodologies and Assessment Criteria Exposure of the subject matters by the teacher followed by practical exercises by thestudents. Execution by the students of technical drawings from 3D objects either provided by the teacher or designed from scratch by the students. Training of the interpretation of technical drawings, getting the students to create a 3D object from the 2D drawing provided. Study tour of manufacturing facilities investigating the design cycle of a produtt from design to manufacturing. Project and manufacturing by CNC of a real object from the digital drawings.
Evaluation based on: Written test - TA (85%); home work - TPC (15%).
Final grade - AV = 0,85xTA+0,15 TPC
To reach "FREQUÊNCIA" it is mandatory AV >= 6,0 valores and a minimum attendance of 50%.
To reach approval: AV >= 9,5 valores.
Language Portuguese. Tutorial support is available in English.
