Effect of Working Tool Parameters upon Plastic Imprint during Orbital Burnishing of Cylindrical Parts

Abstract

The article presents the results of modeling the process of finishing and hardening cylindrical parts by orbital burnishing. A finite element model of orbital burnishing has been developed using SolidWorks software. The model allows determining some geometric characteristics of a plastic contact patch and a plastic indent, during orbital burnishing depending on the parameters of the working tool. The obtained results show that the most significant influence on the size and area of the plastic indent during orbital burnishing is exerted by the angle of inclination of the working tool and the radius of the orbital rotation, the effect of the working tool radius is less significant. With an increase in the angle of inclination of the working tool from 0 to 60°, its radius from 3 to 11 mm, and the radius of orbital rotation from 2 to 6 mm, the length of the indent increases by 1.3–3.6 times, the width – by 1.1–3.0 times, and the area of the hole by 3.7–10.3 times.
