Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters.

Abstract:
This contribution deals with a numerical method developed to estimate how the combined effects of several form and dimensional tolerances, to be applied on a mechanical structure, influence the final three-dimensional location of a single constituting element of this. Reference is made to the space program Planck: problems of misalignment in receivers mounted on a short waves measurement instrument have been analysed. A general numerical approach based on statistical methods has been developed to evaluate the propagation of uncertainties associated with the imposed design specifications. This method has to be thought of as a possible general means for the optimisation of tolerancing during the design phase.
