Concept to Solution: An Overviewdeep-seated interest in solving such problems. As this seems unlikely, we need to ask why a company might want the solution to an engineering problem. The lifeblood of a company is profit. Remove it and the company will die; increase it and the company will thrive. Engineers are employed for the sam

Records and Communications: The Engineering Drawing, builder and salesman are one and the same person. Today, very few engineering products are produced this way. The product complexity and sophisticated controls needed in the producing organisation (to remain competitive), have resulted in organisations splitting into departments specialising in pa

The Importance of Detail: Tolerancescify one dimension for each feature of the component, and provided it was correctly specified and manufactured, a perfect fit would be guaranteed. Unfortunately life is not like that. Precise absolute measurements do not exist in the real world. When asked the time at midday you are likely to reply

Shape Modifying: Retaining Materialnormally requires the use of expensive equipment to turn the unwanted material into chips of swarf. Although the swarf may be recovered and recycled, its value, weight for weight, will be considerably less than that paid for the original raw material. There are a number of alternative processes that

Joining Techniqueseduce the number of components needed in a product as this simplifies both the manufacturing control and assembly processes. However, the vast majority of engineering products require a number of components and therefore need a manufacturing technique to create the assembly. The technique chosen wil

Designing for Joining and Assemblycost. In general terms, the simpler the product, the easier this will be to achieve. One criterion for simplicity is the number of individual components required. More components mean more joints, more potential tolerance problems, and more variety for the manufacturing system to control, and in the
