摘要:

This paper gives the results of an investigation into the design and drawing practices of eighteen engineering organisations in New South Wales. The object of the investigation was to explore the possible economies to be obtained by the adoption of common basic engineering standards in industry. The work incorporates the techniques of a similar project carried out by the Commonwealth Scientific and Industrial Research Organisation, and consists of examining the dimensions and tolerances placed on the detail drawings of a gear pump by the eighteen co-operating industrial firms. The Paper includes a study of each firm's analysis of the given functioning requirements, of the limits and tolerances chosen, and of the drawing practices adopted in the various design offices. A notable point has been the use by the Group of the draft revisio to B.S.164 Part I, Limits and Fits for Engineering, and the draft revision to B.S.308, Engineering Drawing Office Practice. The Group used these draft specifications partly to illustrate the use of a comprehensive scheme of preferred sizes, limits and fits and drawing practice, and partly to test their suitability as national standards. Conclusions are submitted dealing with the impact of common basic engineering standards on the economy of Australian engineering, with the suitability of the draft revision to B.S.164 as a national standard and with the use of logical methods of analysing engineering designs as a means to production economy in the individual firm.
