Analyzing the possibilities of generating the reciprocating motion and plane oscillations of a working member of a vibratory lapping-polishing machine

Abstract

Vibratory treatment is widely used in various industries for performing finishing technological operations, e.g., lapping, polishing, glazing, strengthening (hardening), etc. The problems of maximizing the treatment accuracy and performance of vibratory technological equipment provide the necessity of optimizing the motion trajectory (path) of the corresponding working member. The main purpose of these investigations is to substantiate the possibilities of generating the translational (reciprocating) motion and plane (plane-parallel) oscillations of the working members of vibratory lapping-polishing machines. The research methodology consists of the following stages: substantiating the ideas of improving the vibratory lapping-polishing machines; designing the dynamic diagrams of the machines’ oscillatory systems; developing the mathematical models to describe their dynamic behavior; numerical modeling of the machines’ motion conditions. The obtained results present the possible motion trajectories (paths) of the working member (lap, polisher, grazer, etc.). The main scientific novelty of these investigations is substantiating the idea and possibilities of implementing various motion conditions of the working member for adjusting the vibratory lapping-polishing machine in accordance with the technological requirements, as well as for increasing the wear-out period and durability (normal operating period) of the working member. The obtained results can be used for improving the performance and accuracy of similar vibratory lapping-polishing machines.
