Mechanical Drawing Office

What you will learn

This subject gives you a general introduction to the history of draughting and an orientation of the drawing-office and draughting as a career.  The discipline’s main focus however, is the knowledge required for a mechanical drawing-office.  You will learn the principles of mechanical design and machining. Having this knowledge makes you an invaluable partner in any design team.


Engineering Materials and Heat Treatment

  • Ferrous, non-ferrous metals, alloys and plastics giving properties and uses of different materials
  • Heat treatment


  • Machines: lathe, drilling machine, milling machine, surface grinder and shaping machine • Machining processes: turning, boring, drilling, reaming, counter boring, countersinking, tapping, threading, shaping, milling, grinding, slotting, chamfering and spot facing.
  • Castings and forging
  • ISO limits and fits
  • A visit to a Machine Shop

Measuring Instruments and Freehand Drawings

  • Outside, depth and inside Micrometer, Vernier calliper, Vernier height gauge, Vernier protractor, steel rule, measuring tape, callipers (inside and outside), screwthread pitchgauge
  • Freehand drawings of machine parts with dimensions

Keys, Pulleys, Shaft couplings and Screwthreads

  • Key types, functions, calculations, machining processes
  • Pulley types – purpose, working principles and uses
  • Flange, pin-type flexible, Raffard, universal, Muff, Oldham, Marine and Bibby type shaft couplings
  • Claw, spiral-jaw, single, multiple disc, cone and centrifugal clutches
  • Screwthread profiles

Bearings and Lubrication

  • Plain bearings: radial, thrust and guide
  • Anti friction bearings: ball, roller, spherical, radial, thrust, angular and self-aligning bearings
  • Lubrication

Gears and Gear Drives

  • Gears: rack and pinion, spur, bevel, helical, worm and wormwheel, epicyclic, internal and hypoid gears
  • Gear-tooth terminology and calculations applicable to the construction of a gear-tooth profile

Valves, Pumps and Pipe Fittings

  • Functions of valves, pumps and pipefittings
  • Explanation of work principal and freehand drawings of valves, pumps and pipefittings

Specialist Level

In order to enhance your employability, we add the following learning outcomes to the national curriculum.

  • Project Management
  • Managing a Drawing Office
  • Freehand drawing

Examples of Student Work

This is a theory discipline so most of your projects will be research papers and assignments that test your understanding of mechanical design.

Project assignments include:

  • Measure and Model, mechanical parts
  • Using measuring instruments
  • Visit to a Drawing-Office

    Good morning,

    I’m a little confused about how your courses run- can I take the Mechanical Theory module, fundemental and/or specialist on it’s own? If so how much would it cost and which dates would it run from? Also would it be possible to do the course online and then to write the exams at your campus? I live in Zimbabwe so depending on how long the course I would prefer that optionso that I wouldn”t have to be away from work for too long. I would also like to know the costs for your full program starting in january. Any information you could give me would be greatly appreciated.

    Warm regards

    Matt Robinson

      Hi Matt

      Thank you for taking the time to speak with me on our online chat. As we discussed, I will be sending the relevant information to you shortly.

      I was glad to explain all options that would be best for you and your studies next year.
      If you have any further questions then please let me know ASAP.

      Kind Regards,

    May I please have a breakdown of all the courses and also quotations.

    i have noticed that your programs are basic theoretical, how do we get at an advanced level?

    Also advice, if there is a distance learning option and i would like to have the price list of all the courses please.

    Best regards,
