From working tool kinematics to new finishing-hardening processes

Abstract

The purpose of the work is to analyze the kinematics of the working tool in order to create new technological processes of surface plastic deformation. The article is based on the research results of the degrees of freedom of a working tool under the surface plastic deformation of machine parts. The study of degrees of freedom of the working tool allowed to reveal new motions not used earlier at hardening processing. This served the basis for the creation of new process diagrams and new processes of surface plastic deformation including oscillating smoothing, transverse burnishing by smooth plates, change of the working tool rotation axis, centrifugal rolling of cylindrical surfaces. The performed analysis of the degrees of freedom of the working tool allowed to use new motions and create modern technological processes of finishing and hardening processing by surface plastic deformation.
