  1. MEP201Mechanical Engineering Drawing1st semester 2005-2006 S R Kale. --- Lecture #1 Types of Drawings and their uses in Engineering Projects

  2. Until now : Machine Drawings Prepared and used by • Mechanical engineer • ME diploma holder • Machinists, fabricators, welders, assemblers End result • Component, (sub)assembly drawing(s) • After manufacturing – component, sub(assembly) or machine Lec. 1 - Drawing types

  3. Next step • Someone uses the machine • Not interested in component level details • Needs overall information about the machine Needs different types of information Lec. 1 - Drawing types

  4. Types of drawings • General Arrangement / Layout drawing • Schematic / Process flow diagram / Flow diagram • Process and Instrumentation (P & I) Drawing • Control system diagrams • Piping drawing • Wiring diagrams • Process engineering drawings • Project management drawings Lec. 1 - Drawing types

  5. Example from engineering 1MINI BAJA Bought out – engine, variable drive, brakes, tyres, steering column, shockers, + Manufactured – frame, drive, suspension, + Put them together AND make them work for the race (just like F1) Lec. 1 - Drawing types

  6. Example from engineering 2CSC AIR CONDITIONING PLANT Bought out – compressor, motor, heat exchanger, pumps, cooling tower, valves, switchgear, instruments, blowers, belts, controls, + At site by others – foundation, building, … Fabricated by vendor – frame, pipes, + Pictures of CSC A.C. plant room – slide show Assemble AND make them work 365 x 24 x 7 Lec. 1 - Drawing types

  7. Example from engineering 3 BADAGRAH NALLAMINI HYDRO-ELECTRIC PLANT Visit on 28 June 2004 Lec. 1 - Drawing types

  8. Users of these drawings • Civil engineers • Architects • Electrical engineers • Chemical engineers • Machine builders • Plant designers • Fitters, welders, masons, machinists, • Plus … Lec. 1 - Drawing types

  9. Lecture Summary • Besides machine drawings, there are several types of drawings; • Information about machines - to be communicated with non-ME engineers as well as non-engineers; • Integrating role; • Inter-disciplinary nature of technology Lec. 1 - Drawing types
