Contact Zone Effect Analysis onto the Deforming Rollers Geometrics During the Surface Plastic Deformation Treatment

Abstract

The research studies the problem-solving methods of the parts geometrics in the contact zone depending on the deforming rollers geometrics. The direct and indirect methods are used to solve this problem. Different forms of contact zones were studied. Research results showed that the contact zone form and size do not provide the same working environment. Maximum depth of the roller feeding-in into the part surface and the contact zone volume can be used as such data. This problem solution determines the surface quality influence factors during the parts’ treatment with the surface plastic deformation. The direct method is commonly used to solve the problems about the different deforming rollers geometrics influence and the treatment factors influence on tension in the contact zone and the surface layer quality during the surface plastic deformation. The method consists of determining the contact zone geometric parameters depending on the specific parameters of the deforming roller used in the deformation process. During the indirect method, the arbitrary shape and the size of the contact are defined first, after that, the contact zone correspondence to the type and the size of the roller is determined.
