摘要：This paper presents the results of research on the processing with a multi-contact vibratory hardening tool ball-rod hardener. Theoretical relationships are derived for the calculation of surface roughness, the depth of the hardened layer, and the degree of deformation. The formula for determining the processing time is identified. The technological process reliability with a ball-rod hardener is investigated. Methodology of the process design with regard to its reliability assurance is presented.
