| Summary: | A unified reference system for geometric characteristics is based on the classification
of joints of applied mechanics, in which the class number is determined by the
number of degrees of freedom limited by mating elements of parts and has received
the short term «informativeness». Different information content of the bases of
elements that materialize coordinate systems determines different information
content of the coordinate axes – four, two, zero and different information content
of design planes – three, two, one. The paper shows that the information content
of elements in the functions of auxiliary bases and executive elements determines
the number and type of coordinates (linear and angular), with the help of which it
is necessary to set their position in the generalized coordinate system of the part.
It is shown that the accuracy of coordinating dimensions should be specified by
symmetrical tolerances for linear and angular dimensions. |
