Abstract
The requirement to increase the reliability of the functioning of machine parts and mechanisms while maintaining their minimum cost is considered. It is shown that compliance with this requirement is possible if the blank parts are obtained by cold stamping. However, these blanks have signifi cant shape errors and residual stresses. The infl uence of the shape errors of the base surface of a box-shaped part made of a stamped blank on the accuracy of manufacturing the part has been studied. It has been proved that large errors in the shape of the base surfaces, which are permissible under the conditions of manufacturing technology and operation, are unacceptable when using such surfaces as measuring bases. To reduce the shape error of a large base surface, it is proposed to base a part from a stamped blank during machining and control along two sections of this surface that are remote from each other. These sections must have a minimum deviation from fl atness, for which they are additionally corrected. The design of the mounting device-stand for the implementation of the method of basing on selected areas of a stamped surface of increased accuracy is proposed. The feasibility of such a basing method is confi rmed by the obtained regression dependencies. The application of the proposed method reduces the shape error of the machined surfaces by an order of magnitude and, accordingly, increases the accuracy of parts manufacturing.
