The analytic description and design of workpiece geometry for mechanical engineering

Abstract

The prescription and consumption of material and energy to achieve the necessary and required workpiece accuracy in series manufacturing depends to a great extent from the geometrical workpiece tolerances of any kind (roughness, form, position, dimension) which are prescribed for the production and the realisation of these tolerances and therefore for the function of the produced workpieces and their fitness for practical application and none the less of the economy of production altogether. This requirement is of great importance at the time being which is characterized by shortage of energy and raw material. Adequate knowledge in this area is an important presupposition to achieve wastefree production and low costs of manufacturing with high as possible quality and accuracy at the same time. This is of extreme importance in present time of worldwide international competition in industry and production.
