Companies strive to improve their profitability and a key element to achieve this is the link between product design and manufacture. Geometric Dimensioning and Tolerancing is a standardised system that when understood and used effectively, can significantly reduce manufacturing costs and improve quality.
It is important to understand that no manufactured part can ever be made to an exact size as specified in a CAD model. There will always be some variation in terms of form, orientation or position due to the imperfections of any manufacturing process. It is a design engineer’s role to detail the limits of this size variation, to ensure that the part will still meet its requirements. Manufacturing engineers must then take this design, and ensure that adequate processes are in place to produce suitably finished components.
Obviously, the tighter the controls applied by designers, the more difficult it is for manufacturers (and therefore more expensive), to produce parts. GD&T is an approach to part design that allows far greater control over form, orientation and position of features, as compared to traditional limit-based dimensioning. Whilst this approach initially sounds complicated, it provides flexibility to greatly control the size and position of features to ensure functional parts, and increase the available tolerance on features. These often larger tolerances can reduce manufacturing costs and reduce scrap rates.
