|1. Sketching of a mechanical assembly.
||The sketching of a mechanical assembly by every student will be proposed. It will include power transmission elements and a high number of standard components. The preliminary process, involving the study, information gathering and analysis, will be performed by groups of three/four students.
|2. Modelling of the previous assembly.
||Once the previous practical work has been corrected and given back to the students, the modelling of parts and its assembly will be performed, using the CAD software that is available at the laboratory. Every student will work on his own, but groups will be made for idea-sharing and collaborative learning.
|3. Making of 2D drawings.
||Detail and assembly drawings will be made from the previous models of the assembly, using the CAD software available. The drawings will contain the bill of materials and all necessary specifications -dimensions, macro- and micro-geometrical tolerances, special indications- needed to guarantee optimal operation of the mechanism to which each part belongs.
|4. Representations for metal-working.
||Solid modelling and plane developments will be performed on a metalworking element, including all the necessary dimensional specifications, using the CAD software available.
|5. Making of a report for functionality and
|A critical analysis will be performed on the design of exercises 1 to 4, containing an estimation of the expected operational conditions, based on the applied tolerances and their combined effect. A study showing how the tolerance costs could be reduced based on the combined effect of all the intervening ones will also be carried out. CAE analysis will be performed on a relevant part of the design. All pieces from the report will documented, applying as much graphical information from the course work as possible in order to achieve a better understanding of the document.
|6. Representation of an industrial facility. Schematics of piping works and other installations.
||A small building of the 'industrial unit' kind, hosting a workshop or small mechanical industry, will be represented using the CAD software available, including drawings with all the necessary dimensions and the corresponding construction details of the metallic structure. The symbolic representation of the various relevant installations in the unit: energy, fluids, etc. will be also carried out.
