In work the questions of increase of reliability of agricultural machinery due to application of hardening of a material of the restored details by the vibrational deformation providing increase of quality indicators of their superficial layer at restoration are considered. The matrix of parameters of plastic deformation is presented, the optimal parameters of which ensure the quality of processing of the parts to be restored. The optimal form of the working tool is proved, which ensures a higher quality of processing.

Mathematical dependences of the expression for the deformation force of cylindrical bushing parts from hardened and non-hardened material are obtained depending on the allowance for processing and the slope angle of the working member.

The results of the work provide a basis for substantiating the optimal parameters of the working elements and the technological process of processing when developing the technology of restoring parts by the method of vibrational deformation.
