PRESENTATION/OBJECTIVES - Course contents and working schedules.
 

CP1. MECHANICAL TESTS (40%)- Uniaxial tensile test; analysis of the conventional stress/strain diagram. Main mechanical properties. Hardness tests: Brinell, Vickers and Rockwell. Impact test - Charpy and Izod methods. Fatigue test. Test demonstration, if possible.
 

CP2. MACHINING (15%)- Material removal mechanism. Main movements. Turning, milling and drilling. Machines. Demonstration.
 

CP3. CASTING (15%) - Basic concepts. Green sand molding process. Practical work.
 

CP4. PARTS USED IN CONSTRUCTION MECHANISMS (20%)- Dismantling and assembly of working mechanisms. Measurement instruments, standards consulting and graphic representation of separate parts. Identification of parts, including parts list and the drawing of some components will be included in the assessment.
CP5. SEMINARS (10%)- Metrology; others to disclose.

Learning Outcomes

The objectives (OB1 to OB7) are defined and scheduled in a way that demonstrates the coherence of the curricular contents with the objectives of the course unit. Thus, after successfully completing the course unit, the student should be able to:
OB1- understand the working environment of a mechanical engineer;
OB2-identify mechanical properties of materials and applicable tests;
OB3-perform tests and interpret the results;
OB4-describe the most usual manufacturing processes and equipment used, identifying advantages and disadvantages;
OB5-handling tools and identify standard components used in mechanical construction, norms and the correspondent graphical representation;
OB6-understand fundamental notions of metrology, applying them correctly, including the SI units;
OB7 - handling correctly the measuring instruments, being able to use them adequately.
The competencies sought are as follows, providing the student with the ability to:
- Identify key components used in mechanical construction as well as applicable rules and forms of graphic representation;
- Be familiar with the main manufacturing processes and equipment used in the construction of parts, including a main focus on machining and casting, have a perception of advantages / disadvantages of each manufacturing process;
- Perform and understand the results of the most common tests for mechanical characterization of materials (tensile, hardness, impact and fatigue);
- Identify key aspects of metrology, its importance and correct use, including SI units;
The topics covered in class should motivate the research for additional information.
