| Summary: | The unified reference system for the geometric characteristics of the part is the
Cartesian rectangular coordinate system, which is materialized by sets of design
datums that limit the part to six degrees of freedom: three linear and three angular.
ISO standards for geometric tolerances do not use coordinate systems. In this
context, research in the field of increasing the accuracy of parts by introducing
linear and angular coordinates of part elements is relevant.
The paper presents the second part of the article Unified Reference System for
Geometric Characteristics of Dimensional Elements of Parts, which focuses on the
geometric characteristics of cylindrical elements of parts. It is shown that the datums
of cylindrical elements are the axes of cylinders of maximum material capable of
restricting four, two and one degrees of freedom for the part depending on
the functional purpose of the element. The accuracy of coordinating dimensions
should be specified by symmetrical tolerances for linear and angular coordinates
of elements. |
