ABSTRACT

2D engineering drawings are tools that are used to communicate design intent of component, assemblies, and products and the aspects that are important to their proper functioning. It is, therefore, essential that the cascaded requirements which have been translated into the design specifications are properly communicated in engineering drawings, primarily for the sake of manufacturing the parts (or assembly). This means of communication enables an easy way of relating technical needs to the members of the purchasing organization who are the liaisons to any potential suppliers. The sooner these drawings are developed in the design process, the sooner supplier feedback may be solicited to identify alternative manufacturing approaches that may reduce cost; or to ascertain primary and alternative processes. Finally, from a systems point of view, these documents provide the rationale on how factors that were called CTQ cascaded down to design specifications and ultimately the final product.
