TECHNICAL INDUSTRIAL DRAWING A - L

The course aims at providing the graphic communication concepts and technical drawing, so that the same is able to represent and interpret through the reading of the drawings, the individual components and assemblies of machines, identifying shapes and technological characteristics and functional. The student will also gain an initial knowledge of standardized functional components of machines and design procedures. They will finally be shown the basic elements of computer graphics and solid modeling.

1. DESIGN FOR THE DESIGN - STANDARDS AND INSTRUMENTS FOR DESIGN The technical design and its evolution. The design behind the industrial design. Conventional representation standards, dimensional scales. Standardization and unification. Industrial Unification. national and internazionali.Strumenti unified regulations for the design 2. PROJECTIONS AND SPELLING isometric projection of a point in space, the Monge theorem. Orthogonal projections. European screening method, American and arrows. Outline of subsidiary plans. Unified axonometries: orthogonal and oblique. Isometric, dimetric and cavalier. Theorem Polhke. 3. SECTIONS AND INTERSECTIONS Sections and representation standards. Sections in planes parallel to and competing plans. Outline of interpenetration between solidielementari 4. Dimensioning The dimensioning. Main types, special quoting conventions, classification of shares. 5. TOLERANCES DIMENSIONAL AND GEOMETRIC Errors and tollernaze. dimensional tolerances, types of coupling, ISO system. Tree-hole pair. Outline of geometric tolerances. normal numbers. Surface condition, roughness and surface finishes. 6. CONNECTIONS shaft-hub couplings by hot forcing. Sticks, tabs, splines and plugs. The threads, the main thread types (metric ISO, gas, Whitworth, trapezoidal, saw-tooth, Edison, etc.), The main elements of a thread. The main threaded elements, screws, bolts, studs, nuts and bolts classes. Notes on welding and on nails. 7. MOTION TRANSMISSION AND OTHER PARTS OF THE MACHINES sliding bearings. thrust bearings. Rolling bearings, ball bearings, roller bearings, conical, in the cages. bearing graphical representation. Selection criteria and their assembly. transmitting the rotary motion (transmission ratio, friction wheels). Sprockets, type and their representation seals and gaskets. Soft. 8.
