Abstract

International Standard Organisation (ISO) system of limits and fits
used in linear tolerancing is published in relevant international standards and
recommended for use worldwide. Due to ambiguity in these standards, in some
cases the data and the technical terms given in the standard may be
misinterpreted especially when used in automated Computer Aided Design
(CAD) modelling systems. The objective of this research work is to clarify the
procedure of determination of the fundamental deviation of a tolerance. This is
necessary as to radically improve the product development cycle by reducing
the modelling time. In this paper, a new universal formula for the calculation of
the correction ', which supersedes some numerical data from the standard that
could be potentially misused are presented. Some amendments related to the
key technical terms have been offered to bring agility to the linear tolerancing.
