Learning objectives

This course aims at teaching the fundamental knowledge for studying the functional and constructive features of mechanical devices, by means of drafted representations that comply with technical standards, and according to their choice as a consequence of the production process.
Students will develop the awareness about technical drafts, both for single parts and for assemblies.

Prerequisites

None

Course unit content

At the beginning of the course there is an introduction about the basics of technical drafting, such as geometric constructions, orthogonal projections, axonometries, representations of surfaces, sections, rotations and reflections, intersections and flattening of developed surfaces.
After some forewords about science of materials, metrology, machining, this course thoroughly deals with typical issues of mechanical drafting, considering most used standards, conventional representations, and most common principles of dimensioning. Relationships with production and control processes are carefully taken into consideration.
Further topics are dimensional tolerances, geometric tolerances and surface roughness.
There is a thorough analysis of separable joints (by means of threaded parts, keys, locknuts and straight-sided splines), fixed joints (welding, soldering) and elastic connections (by means of springs).
Other topics are bearings and seals, along with several application examples, with special emphasis on the methodology which lead to their choice and mounting.
The course deals also with mechanical transmission devices, such as shafts, joints, belts, chains and gears.
Devices for regulation and delivery of fluids are described along with the principles for their adoption.
