【 摘 要 】

The paper considers the issues in and provides recommendations for dimensional analysis performed during the design stage of axisymmetric parts manufacturing processes. Conducting the dimensional analysis with the method proposed in the paper allows: calculating the wobble (rotational error) of the rotating elements that arises during various operations of the manufacturing process; checking for possibilities to ensure the given requirements of mutual spatial arrangement of surfaces for a piece of equipment selected automatically, using verification only where it is justified; determining non-uniformities of machining allowances and performing final calculation of all the machining allowances and intermediate diameter sizes.
