Determination of accuracy in finishing machining trough surface plastic deformation with account of the phenomenon of technological heredity.

Based on a performed analysis, an analytical method is proposed in the paper, for determining the accuracy during processing, taking into account the mutual influence of the components of the total inaccuracy. This is of particular importance in the processes of finishing treatment, such as surface plastic deformation (SPD), where technological heredity and the formative technological environment play an important role in forming the quality of the finished part. The matrix approach is applied, describing most fully the mechanism of formation of the constituent inaccuracies, taking into account the phenomenon of "technological heredity". The sequence for determining the transformation coefficients is given, by which the degree of mutual influence of the constituent inaccuracies in the interaction of the workpiece with the technological environment at the level of an operation is shown.
