Type of Assessment - Last names A-L
The level of knowledge acquired will be evaluated by three intermediate tests during the course.
Topics of the first test will be: geometric and dimensional tolerances, roughness, stress and strain states, Mohr circles. The second test will be focused on casting and forging processes, while in the third test issues related to machining will be considered.
Students that will not met performance required, will have to undergo a comprehensive written evaluation test (1.5 hour) and an oral examination. Students that will not fully met the performance expectation, will have to give just an oral examination.
Tests and oral examination aim at highlighting the acquired knowledge cc3 e cc12, and verifying the capabilities ca3 e ca10.
