The philosophy behind the engineering design primer is to introduce student engineers to the world of engineering design. Most student engineers start in the drawing office as draughtsmen and the majority stay there for the duration of their working lives with little thought of progressing into design engineering. From the authors experience, the drawing office lays a very good foundation for a career in design and allows the student to explore the many facets of design.

The first part of the book introduces the student to the workings of the drawing office together with the working principles of producing a drawing having sufficient detail to enable the part to be manufactured. covers the principles of the design process followed by the design specification or PDS. This is the singular most important document in the design process as it lays down the definition of the design in so far as what the company will produce and most importantly what the customer is expecting.

covers Design for X discussing such items as manufacture, reliability, robustness, maintainability and serviceability. Life cycle costing is also discussed in this chapter.

Quality is discussed in Chapters 6 and 11. It is important for the producer that the customer has the utmost confidence that the product they buy will meet all their expectation.

I make no apology for discussing probabilities and engineering statistics as these items are important when discussing reliability.

The book is rounded off with chapters on material selection, mathematical modelling and configuration management, the later covering change controls. Communication is an important attribute for the budding designer to stand up and confidently and clearly to put his case across for the adaptation of his/her design.

The author wishes the readers every success in their respective design careers and hopes it will provide them many years of employment as, it has for him.

Keith L. Richards is a retired mechanical engineer with industry experience of over 55 years. He served an indentured apprenticeship with BSA Tools that manufactured a wide range of machine tools including the Acme Gridley, a multi-spindle automatic lathe built under licence, and single-spindle automatic lathes; these were built in Britain and widely exported all around the world.

On leaving the BSA, he served as a freelance engineering designer in a wide range of industries, including aluminium rolling mill design, industrial fork lift trucks and was a lead engineer for the mooring system for the Hutton tension leg platform. In later years he became more involved in stress analysis that led to working in the aerospace industry covering landing gear and environmental control systems for both military and commercial aircraft and trailing wing components for the Airbus A380.

Over the last few years the drawing office has seen a massive revolution. Digital draughting has replaced the original method of paper and manual drawing, and alongside this major change there has been a technological revolution in the way drawing prints are now processed and the way data is now transferred to the multi-axis machining centres on the shop floor.

Drawing offices used to be quite noisy with general chatter and heated discussions, now all this has been replaced by a quiet environment with only the clatter of keyboards to be heard. Any major discussions are carried out in side offices to the main drawing area.
